Looking for the right size capacitors
« on: September 05, 2018, 01:29:04 pm »
I've recently been looking at repairing a game boy where I've found a few of the electrolytic caps that have bulged. They haven't leaked yet, which is nice.
The thing is I can't find the same size capacitors.

Here's the list (w=width=diameter, h=height=length):
Cpu:
  100u 10V x2 w6.5mm h5mm
  10u 16V x2 w4mm h7mm
  1u 50V x2
Power:
  33u 25V x1 w6.5mm h5mm
  100u 10V x1 w6.5mm h5mm
  22u 10V x1 w4mm h5mm
Audio:
  100u 6.3V x2 w4mm h6mm
Lcd:
  100u 10V x2 w6.5mm h6.5mm
  10u 25V x1 w4mm h6.5mm
  1u 10V x5 w3mm h5mm

I've measured the body of the caps with calipers.

I've opened 3 of my game boys and 2 of them are Panasonic brands and the 3rd one is Sanyo, yet I can't find the right one on digikey nor in the sub miniature elcos category on reichelt.
All I've found so far are 5x7mm (WxL).



Does anyone know where I could find these ?

What's the lead pitch? How about using smaller diameter capacitors and bending the leads?

How much clear space is available above the PCB? Could slightly taller capacitors be fitted?

The voltage rating isn't important, as long as it's equal or higher, than what it replaces.

The lead pitch is 0.5mm. The 100u caps have to be straight, but it looks like I have enough space for a taller one like the 5x7mm I found.
I would prefer to have original looking caps though, but if I can't find them then I'll have to get those ones.

Function first. If you get an electrical match and the parts can be mounted securely that should be you concern. I would also pay attention to any special requirements like low ESR. The inside of a box is not for show.

Any reason a ready-made capacitor-kit for the DMG Gameboy won't work?

It's easier and cheaper than sourcing the individual caps yourself.

The lead pitch is 0.5mm.
I'm certain it is not, because the lead pitch can't be equal to or less than the thickness of the leads. (Pitch is the distance between centers of the leads.)
