Thanks for that ! It was rather unexpected considering the time I'd spent searching.

15pF and 33pF capacitors harvested from a precision(±0.25hPa)barometer; pin spacing 3.81/4mm. Any details(or even datasheet) would be welcome.

[sharbinger]

These have been eluding me for days now. The inverter buffer and the NAND have been eluding me. Elsewhere there is an inverter buffer, a 74HC14 that is just labeled as a 7414 which has made identifying other unknowns harder.
the IC in the second photo is also completely eluding identification. It's not listed in the board description and this is the best available quality. It's interfacing between a Philips 87C51 and a 16550 UART IC as well as connecting the mcu to a buffered output set and a set of optoisolators for controlling an isolated power supply and a mosfet waveform generator.
I attempted a teardown of the unit I have, but mine is a new model later and the other half is a model revision earlier, so no parts of mine match the schematic 1:1
Any help would be extremely appreciated as i'd love to get this machine working to post an actual repair

easy to find.

I'm currently sorting through a large haul of parts from a closed-down radio/tv sales and repair shop. As the owner has passed away, there's not much additional info available to me. After having spent the last couple of evenings and weekends on Google and looking at old databooks, there are still some unidentified parts left.

First up is a huge bag of identical transistors. They were still in a sealed plastic bag, but the only markings on the bag are the logo and address of the parts distributor (Völkner Electronic, Braunschweig, Germany). As the bag has a 4 digit postal zip code (today 5 digits), the parts must have been made/sold before mid-1993.

Markings are:

Code: [Select]

D-P
S16

Package looks like it could be the "E-Line" aka "Miniplast" variant of a TO-92 (https://en.wikipedia.org/wiki/TO-92#/media/File:Miniplast_vs_TO-92.jpg):


And here's the results from my tester:


Then there's also a huge part (transistor?) made by Texas Instruments. Basically a black cylinder/can with the TI logo and the number 355 on top of it and also the number 980634 printed on the side:


Can anyone here identify these parts and maybe also has a (link to a) datasheet?

Any help would be appreciated.

[helius]

The TI 355 is a germanium PNP: https://www.radiomuseum.org/tubes/tube_ti355.html

[rsjsouza]

Indeed it is probably Germanium, but on a TO-36 package.
https://eesemi.com/to36.htm

It might be the 355 transistor or perhaps a different one. It was not uncommon to have house numbers for specialized transistors like these (one example).

To make things interesting, there is a JEDEC registered 2N355, but for Philco and with a very different package.

MPS-A16

[BlackLotus]

Thanks for your replies

I don't think the small ones are MPS-A16, at least i didn't find any further information (old databooks, etc.) that would indicate so.

After a couple of hours of further research, i now think they are potentially RFT SS216(D), made in former East Germany. I also found an eBay listing with highly similar looking transistors (https://www.ebay.de/itm/125812946187). The only "weird" thing is that the SS216(D) datasheet says the pin order is EBC, but my tester indicates CBE. Was the pin order something that (back in the day) could change sometime, maybe with special orders (or like an "export variant sold to West Germany"), or might have been switched around due to production error?

Regarding the big ones (TI with "355" marking): Not sure whether they really are "TI 355" (like the 1969/70s ones shown on the @helius Radiomuseum link).

But yes, the lower part of mine look quite like a TO-36 package, but the upper part (the "can") is much taller (about 1cm) than spec TO-36. The upper part / can looks a bit like the can (without the flat wide bottom part) on the 970/J252 shown at the bottom of this page, which interestingly also has a 6 digit number on it. They are also similar in design like on the subsequent two museum pages.

The date code 980634 seems to indicate they were made in week 34 of 1956.

Still a bit of a mystery, though.

[helius]

1956 is squarely in the era of germanium transistors; they certainly were not making many germaniums in 1969!

[tigrr]

The only "weird" thing is that the SS216(D) datasheet says the pin order is EBC, but my tester indicates CBE.

However, the original datasheet indicates the correct transistor pinout - CBE. Perhaps you have come across an incorrect datasheet with the EBC marking.

Can anyone identify these 3 ICs?

https://forum.hddguru.com/viewtopic.php?f=10&t=43285 (thread)

https://forum.hddguru.com/download/file.php?id=25972&mode=view (MAY + 70B + A2P + 804)

https://forum.hddguru.com/download/file.php?id=25973&mode=view (BC2G + 740 and AM2K + 750)

"MAY" appears to be comprised of two bucks which power the flash controller cores (there are 3 cores).

"BC2G" and "AM2K" (?) are two step-down converters which produce 1.2V and 1.8V (?).

I'm wondering whether "MAY" could be a custom PMIC by Marvell. The controller is a Marvell 88SS1093.

Agreed, but that's all I'm going to get. This same guy used to post images that consisted of illegible black rectangles until I shamed him into throwing away his potato camera.

Hello.
I'm using a LilyGo TSIM7600X device and I'm trying to locate and identify the battery charger IC which I was told to be a CN3068 but I wanted to confirm on my device because something is not adding up. Who told me about the IC, was the support themselves. I asked them, because the shcematic says they use a CN3065 but then, my device has a new board revision and I asked support what changed from the last revision to this one and they told me the only thing they changed was the battery charger IC from a CN3065 to a CN3068. But they didn't update the docs.

What I'm finding weird is that the board says that the input for the battery charger needs to be in the range of 4.4V to 6V. However, this seems to be the requirements for the old CN3065, according to its datasheet (4.35V-6V).
The only reference I have for the IC on the board is a "THY" which I have no idea how to identify! Image attached.

How can I confirm this is a CN3065 or a CN3068? Any possibility?

[Fryguy]

Found it - your THY chip is a CN3165 in a DFN-8 package !

[psysc0rpi0n]

www.shotech.de/Datasheet/consonace/DSE-CN3165.pdf

Can you teach me how are you able to reach such detailed conclusion? I mean, From THY alone, how can you tell the brand, model, etc?

[Fryguy]

The schematic already says it is a CN3065 and the hardware around it was not changed , the support told you they only changed the chip - so the chip in question must be something really , really close to a CN3065 . . .

I checked the entire chip family and found the marking THY and the package visible on the photo in the datasheet i posted - same function , pinout , block diagram . . .
My guess is , the CN3165 is a newer version - it's got small differences in it's working behavior .

Close enough ?

Ok, but I was also said that they changed the CN3065 to a CN3068. However, I can't find any major differences between the 2 ICs, at least in terms of input power. I think the major difference is that CN3065 uses a linear current to charge the battery and the CN3068 uses pulsed current or something like this. Also the latter has some kind of heat management that allows more efficiency.

I was just checking the 8 pins of the IC to look for pulsed voltages, and I couldn't find any, which makes me think that there is no CN3068. Or it's still the CN3065 or the CN3165 you mentioned!

Edit:

Another possibility (FH4063D):

https://fordevices.com/UploadFiles/2022-07/16579639382767530.pdf

[Fryguy]

Yes , the FH4063D is the exact same chip as the CN3165 - i'm sure they come from the same factory . . . 

[psysc0rpi0n]

Ok, I got a reply today from the support. And in fact, you guys are right. The CN is in fact the CN3165.

Thanks

Hi.

I need help to identify a few other components because I'm looking for a specific one. I'm looking for a p-channel mosfet Si2301 in my LilyGo device and I cannot find one that matches.
I took a few screenshots of some of the components present on the board of the device. I think I could identify some of them.



A1SH I think it's an Si2301 mosfet


AS20Be
Couldn't find anything matching the schematic.


3401 1RPD
Is this an AO3401 mosfet?


XR1151 3u
Seems to be a XR1151 mosfet.



These 2 are the same screenshot but from 2 different points of view because I couldn't see the references very well in the 1st screenshot.
H3 - Found somethinf in AE, shown in H3.png attachment. Need confirmation, please!

PS: I couldn't add more screenshots so I add here the list of possible references:
UMH1N H1 UMH2N H2 UMH3N H3 UMH4N H4 UMH5N H5 UMH6N H6 UMH7N H7 UMH8N H8 UMH9N H9 UMH10N H10 SOT363 Digital Transistors
Could it be these ones?

J2RD ?? - Couldn't find anything for this one.


T1A
Fisr tthing that showed up were fuses but with 3 legs, I'm not sure it can be a fuse!


DW01S
Schematic shows DW1FA. Not sure they are the same. Need also help here!


A09T
For this one I found several matches but no idea which one would be my case.
Not sure why but I couldn't add more inline attachments to my post. It's the attachment named a09t.png.

A09T AO3400

DW01S DW01

T1A PMBT3904

J2RD ME6217C33
