Title: Datasheet Database
Post by: webkraller on October 15, 2009, 05:07:17 pm
This site has a great concept - easily searchable datasheets.
I just thought I'd pass on the resource, and hopefully some of you will be able to contribute to help it grow!

This isn't cheap for a hobbiest, but it's really useful

Ultra Librarian
http://www.accelerated-designs.com/(S(msz2wx55m1tmdb45pm5qyu55))/home.aspx

It has a bunch of parts + foortprints via an online database that then can export to a bunch of different EDA software, you can knock out a new part in minutes.

doesn't contain the whole datasheet, but still very worthfile.

adding filetype:pdf is a good googlism i usually add a -inventory as well to get rid of the part miners.

I'm a Beginner with a capital "B". So I'll certainly give it a try. I've been looking for something better. My biggest issue is in finding an understandable cross-reference. My Mickey Mouse Radio Shack Learning Lab came with transistors simply marked C9014. I can find data sheets easy enough but when I try to find a place to order them they offer NPNs with numbers other than that (but not the 9014). So I need some way of knowing what will interchange. Thanks

There are so many transistors out there it's nearly impossible to cross reference them. You sort of just have to dive into the datasheets and get close, looking for the special bits that are unusual. If you're not doing anything particularly special then almost anything that's the same polarity (PNP vs. NPN) and size (TO92 in this case) should work ok.

Here's a good writeup on selecting a replacement transistor. (http://www1.jaycar.com.au/images_uploaded/transubs.pdf)

Hope that helps some. :)

Can't remember how I found it but it'll search partial part numbers better than Google if you're trying to identify a part.

For me the best place to look for datasheets for jelly-bean components - is http://www.datasheetcatalog.com/ (http://www.datasheetcatalog.com/)
Not google, because in datasheetcatalog you can select datasheets from different manufacturers for a given component.

Usually when searching for components I use two websites: http://DigiKey.com/ (http://DigiKey.com/) and http://www.datasheetcatalog.com/ (http://www.datasheetcatalog.com/) (o, well, and google of course)

But I wanted to tell you about one thing that _really_ speeds up searching for datasheets.
It's a small browser tweak I use - search engines keywords.

For example: If I want to look for BC817 datasheet, I just type "d BC817" (without "", of course) in my browser address bar. And momentarily I'm getting list of datasheets from different manufacturers for BC817 from datasheetcatalog.
The same way I can search for videos on youtube typing: "y SomeVideoNameToLookFor" or on wikipedia "w nuclear reaction", etc.

To add DatasheetCatalog to the list of search engines I've used "Add To Search Bar 2.0" firefox addon (which you can find in list of official addons).
I've included some screenshots - they're pretty much self-explaining.

What's wrong simply grabbing them from the manufacturers website ? All those cyber-squatter sites like all-datasheet and others do nothing else but make you jump through hoops to get a pdf file. And very frequently they present you the wrong one. I have a lot of instances where you land on these sites and the datasheet isn't even there.
Another problem is that they often have old versions of the datasheet with outdate information or mistakes.

my advice : ALWAYS go to the manufacturers site FIRST. if you don't know the manufacturer : go to Digikey or Mouser websites and type in the partnumber. you will get a list of parts: 99.9 % of the parts these guys sell has the link to the REAL datasheet from the manufacturer. Simply click on the icon there and you will have the latest version.

If it's an obsolete part THEN, and only THEN can you use those garbage collectors, and spewers, like alldatasheet, chipfind. There's even an outfit that sells you a subscription to their datasheet collection. These guess essentially sell you PDF files that they do not own , or are licenced to sell. ( yes the datasheets do carry a copyright by their writers and companies that own them)

Google relly needs to make work of eliminating all those datasheet squatter sites.

They corrupt the datasheets, inserting their ads and trashing metadata (set document title to their website name, insert pages and watermarks...). They also pollute the search results with their entries, shifting legitimate manufacturers sites down into oblivion.
I block most of the datasheet sites in my google search for that reason.
I'll take the datasheet from manufacturers site, thank you.

To make life easier i've made a bookmarklet, to find datasheets, this is the code:
Code: [Select]
javascript:

   url="http://www.google.com/search?hl=en&&btnI=I%27m+Feeling+Lucky&aq=f&q=filetype:pdf+datasheet+"+part;

.... with transistors simply marked C9014. I can find data sheets easy enough but when I try to find a place to order them they offer NPNs with numbers other than that (but not the 9014). So I need some way of knowing what will interchange.

Back in the day, I used to rely heavily on ECG Master Replacement Guide for transistor cross references and specs.
I actually pulled 1996 copy off the book shelf, looked up C9014, and found it. (equivalent to ECG123A / NTE123A).
Anyway, all this is available via online search now -

Note that only the main datasheet for a part cannot be enough.

Most (digital) parts have errata sheets, that require careful reading if you don't want to get stuck for DAYS at an odd problem. And you do want to have the most recent version, claiming (hopefully) all the bugs for each silicon revision.

Some CPU datasheets have separate user manuals, summary datasheets, or microchip even list each peripheral in it's own document. For a PIC32 there are like 24+ PDF's on 1 chip's page , all with useful information.

Then there are application notes, sample schematics/projects and/or evaluation boards that can be useful for designing as well. These are neither found on these generic websites.

Chances are you won't find these very useful documents easily (or at all) on alldatasheet.com or a like.

You should avoid all the plethora of crap WowLotsOfDatasheets GetYourDataSheetsHere.com sites that are out there, you'll find nothing but ads and banners and crap, and you'll be jumping through hoops trying to find the datasheet.

Do a Google query, and look at the results carefully - pick out the ones that are direct links to PDFs, especially if you see the name of a recognised semiconductor/electronics company in the URL - this approach will help you filter out the crap and go directly to an accurate, usable datasheet with no bullshit.

Or, look up the part using a major distributor such as Digi-Key and from each Digi-Key product page you'll get a direct bullshit-free link to the datasheet with a single click.

I find that the manufacturer is usually the best place to go, as others have said. But sometimes an obsolete part from an old circuit may not be listed. I use these resources in order of appearance, and haven't failed in finding what I am looking for, well, so far!

1. Manufacturer Website
2. Distributors - DigiKey (http://www.digikey.com), Mouser (http://www.mouser.com), Element14 (Newark in USA) (http://www.element14.com), Arrow (http://www.arrow.com).
3. Datasheet Archives - IEEE Datasheets 360 (http://www.datasheets360.com/), and Octopart (http://www.octopart.com).

Octopart is pretty cool as you can search for your parts, and they show you which distributors have it in stock and the price comparison happens in the search results. You can also access the datasheets there. Octopart is owned by Altium, I believe.

I hope this helps someone!

Personally I recommend that beginners don't waste their time with crap like alldatasheet, datasheetcatalog and the like. Just ads and spam.

Try a Google for the part and see what results you get. Look for direct PDF links from the reputable semiconductor companies, or try their websites directly if you can identify the device manufacturer.

Or try a distributor like Digikey. Look up the part and the product page will give you a no-fuss datasheet direct link.

wow what a great thread.

IMO there are two sites which are very useful:
The 1st is the great alldatasheet, it has a large number of parts pdf to download.
The 2nd is the https://upverter.com (https://upverter.com), It has a useful feature named Parts Concierge.
And the best for me is Datasheetr datasheet info site (http://www.datasheetr.com), which is super fast for me to search info when I do design.

https://www.semicon-data.com/index.html (https://www.semicon-data.com/index.html) some PDF's require an active account to be opened .I use it to cross reference older numbers to new ones.

just google the part and within the first page there will be at least two results from datasheet archive sites
i tried this with one diode i have: DECIA7 and no you dont get a datasheet therefore propably a subject for a thread on its own

Can anyone point me to a datasheet for the 2SC2291, it seems pretty non-existent  :wtf:

Here's a public FTP server that's chock full of schematics, datasheets and various other goodies including stuff for laptop motherboard repair.
ftp://helpedia.com/pub/temp
About 100+GB of stuff

where do I find the datasheet for these two SOT23-3 package (Attachment)
Google does not give me much.
SMD code
DFJC -sot23-3
E5JA -sot23-3

I am surprised  ??? that no one ever mentioned about https://components101.com/ (https://components101.com/)

This place has been a life saver for me, it not only provides datasheet but also explains how to use that component or sensor with application circuits. It is especially useful for beginners since it covers a lot of modules and sensor which sometimes does not have a proper datasheet  :-+

The manufacturers website and distributor pages are the best source, those datasheet sites could be out of date or show data sheets from different manufacturers. Many jellybean parts like the 2N7000 come with various specs and pin-outs.

Just wanted to pitch in here as the person that keeps all the documentation on our website up to date. We only keep our own site up to date - we do not have agreements with any of these other sites mentioned to feed them with the latest version of any drawing. As for distributors, we feed our authorised distributors a list of links so they can link direct - if they are taking their own copy we can't guarantee it's up-to-date I'm afraid.

As an engineer I also would go straight to the manufacturer first whenever possible, for the same reasons. However, I do realise that not as many older or obsolete drawings are kept on manufacturer websites, and these sites may be useful for these documents. Other manufacturers may also have larger teams that can ensure documentation is kept updated at other sources.

A lot of data sheets are not available to public...

One more to add:

http://www.datasheetarchive.com/ (http://www.datasheetarchive.com/)

I am fairly new to finding out what part I have. I like salvaging items from boards.

For example I have a part that has d2396 on one line. On a lower line are a  J and a strange T 08 and at the top it looks like an R.

When I did a search for d2396 I got d2396 from Bristol Electronics and I also found a    2SD2396K from Digikey.

Can you tell who made the chip?

Is there any consistency on the markings?

P.S. I saw a video with a guy reviewing a electric vacumn desoldering gun. It made short work of removing chips, etc.

Is there somewhere a look-up-table for all the abbreviations used in datasheets? I get Vr, If etc. but I am quickly lost after that.
