Trying to rebuild a very old hard drive and need tantalum capacitors. I need 7 of them and have 3 pics of the caps I need.
THANKS in advance!!
Hi there, @slebel!
Here’s what I’m seeing after looking into those capacitors.
For the first photo- looks like part number 399-3721-1-ND.
For the second- that looks to be part number 399-3714-1-ND.
And the third- this looks like part number 399-3781-1-ND.
In the last photo I have 5 caps are they all the same value?
Hello?? :-/
Hello again, my apologies for the delay. I’m looking over the parts in the last photo again. For some reason I thought that just the one at the top was highlighted in your last photo but I see now that you said all of them need to be replaced. I should have an update shortly, I just wanted to let you know that this thread wasn’t abandoned!

Okay, so for that third photo here is what I have. The three tantalum caps that I outlined in red are all the same value, and part number 399-3781-1-ND should still be a good option for those.
The other two are as follows:
The one near the top, outlined in black, is 47uF and part number 399-3793-1-ND should be a good match.
The one on the bottom left, outlined in blue, is 33uF and part number 399-3787-1-ND should be a good match.

Hi Chris I need another set of Tantalum caps on the other side of the board. There are 8 all circled in red. You can zoom the pic to see the #s.
THANKS Chris!!!

Hello Slebel,
For the one marked 225/20k/316, it appears it would be 399-3714-1-ND.
For the one marked 105/35k/315, it appears it would be 399-3702-1-ND.
For the one marked 475/10k/316, it appears it would be 399-3721-1-ND.
For the one marked 226/20k/325, it appears it would be 399-3781-1-ND.
Hi and THANKS for the reply!! I have noticed that the last one the 226/20k/325 is a 226/20k/323 not a 325. Can you give me the right part # for that one please, THANKS!!!

Hello? Need part #
Hello slebel,
It will be the same part number. The 323 or 325 would just be a Date code. First digit is the last number of the year, so 3 is for 1993, 2003, 2013, 2023. The second 2 numbers are for the week of the year, so 23 is the 23rd work week of that year. So the info on the last number would not make a difference to find the part number.
