Help indentifying SMD caps

This is for my beloved SNES. Kind of off-topic, but I know you guys in here rock with this hardware stuff.


SMD caps:
1x 2.2 50A (Yes, 2.2, not 22)
2x 33 25A
1x 47 16A
3x 10 16A

They look just like the ones on an A600/A1200 mobo.
So, what are their specs? Want to buy new ones from futurlec.com, as one of the 10 16A ones were leaking (!).. Managed to clean up the acid, it's all good now.

Should I replace them all since I saw one leaking, or should I just exchange those who look bad? The rest looks perfectly good...

In for a penny, in for a pound. Change em all. if one is leaking then the rest are doomed to follow. As long as the physical size of the replacements is the same and the voltage rating of the replacements is at least equal or higher then you are good to go. Try to get the highest hour rated ones, sometimes you cant compromise on quality

SMD caps:
1x 2.2 50A = 2.2µF x 50 Volts
2x 33 25A = 33µF x 25V
1x 47 16A = 47µF x 16V
3x 10 16A = 10µF x 16V

µF means micro-farad

Okay, all parts ordered Will give this SFC a new life.. It's an almost mint one, in a box.. Paying $8.37 to fix it (for parts and shipping) is for sure worth it.

Wohoo!
Before: No sound at at all from the SNES, and weird behavior
Today: Crystal sharp sound and stable system
What did I do? Exchange all the caps!

Just listen how beautiful my SNES sounds now:

(Recorded from my real Super Famicom of course, silly)

Well, it wasn't easy... I did a trick to make it much easier, albeit makes them more fragile:
You know those small SMD caps with a black socket? I removed the socket, bent the pins down, and soldered the pins right on the mobo.. MUCH easier, but they break too easy, so be careful. I ordered many of them from Futurlec, in case I messed up (as I did, sometimes)...

I changed the through-hole caps as well.. Easier than the SMD ones.. If you feel comfortable with doing these stuff, then I recommend you to do it on your SNES just in case! They die pretty fast when they're old...
