While trying to service an AppleCD 150 (Sony CDU-541-25), I found a cracked component at C315 that I cannot identify.


Assistance in identifying a suitable replacement would be appreciated.

This is a tantalum capacitor.
Are there any markings whatsoever on this capacitor?
Given the size, it could be 10uF 16V or similar, but you can't be sure.

I agree, something is written in the black casing, probably a clue here

Just a quick googling around and I found a photo of the PCB which I cropped.
The C315 is marked C105, which means a 1uF 10V tantalum cap!

You can also use a ceramic 1uF cap in place of

wonderful, much better google-fu than I. Much appreciated, one step closer to installing A/UX...

And I'm guessing bitsavers as the source; to help increase hits

Yes, exactly, good catch!
Hope you get it working. I recapped a similar unit back in 2015 and I remember it had quite a lot of leaky cap damage
