Just as valuable as finding a data-sheet is finding out if a given part is actually available.
I find this website invaluable...

I'm either at my bench, here, or on PokerStars.

I find this site great for finding datasheets:

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.

i use digchip for most of my sheets usually from boards i salvage. i have a whole folder full of the PDFs from there
im a picaxe fan particularly the 08M's

You can use 2N3904 or BC547 for the NPN and 2N3906 or BC557 for their PNP complements.

I like to use the sites where i buy them from Digikey or Jameco usually, some times Jameco cuts out some information, but usualy the important stuff is there, that or i go to the manufacture.

For me the best place to look for datasheets for jelly-bean components - is
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: and (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. - Electronic projects, tutorials, hacks, etc.

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.

here is a transistor database, it also other than the search function lists near drop in replacements for even some of the more obscure stuff, it also for 90% of the stuff lists relevant datasheets for them,

edit: forgot the link

Guess I'll add this handy on-line vacuum tube database for all those tube nuts out there:

Not so much a datasheet website, but this site has got lots of schematics and service manuals for loads of stuff:

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.

I usually just google it like

filetype:pdf datasheet PART

To make life easier i've made a bookmarklet, to find datasheets, this is the code:
Code: [Select]
(function(){if(part=prompt('Search Datasheet','NE555')){

Or simply go here
Datasheet Finder Bookmarklet

I hope this was useful

Another one worth keeping around:

Lots of old databooks here. Unfortunately the site is insanely slow. Like... 56k modem speeds. Not good when the PDFs are 20+MB.
