Default 220uf 16v replace with 220uf 25v?

is it possible to replace 220 uf 16v with a 220uf 25v? I know you can go up in uf by about 10-20% but what about volts?

Thanks
Chase

Depends on the application. One step up in volts is fine, in most cases, and usually within a brand/series there is no trouble.

It depends on the characteristics of the cap you are replacing vs. the cap doing the replacing. Reviewing the datasheets/specs is the best/safest way to be ~fairly~ sure.

Example:
Using a Nichicon HZ (super low ESR) cap where a Nichicon PW (medium low ESR) cap was, may cause problems upstream with the circuit. Same as if you used them the other way around. Circuits are designed using a specific type of cap with x/y/z characteristics which are figured in the engineering formulas at the design level.

Voltage Scale:
4-6.3
6.3-10
10-16
16-25
25-35 or 25-50
50-63
63-80
80-100
100-etc.

Thanks for the replys. Ill give it a try and also read the data sheets on both caps!

I have 220uF in both 25v and 16v, in both Rubycon and Samxon. If possible, stay with what came out originally.
