Can I use a higher voltage rating when replacing capacitors?
Replacing a capacitor with something that has a higher voltage rating is always safe. The only problem there is that a capacitor rated for a higher voltage is often physically larger, everything else being equal. Make sure they actually fit in the same space. Sometimes it is also safe to use capacitors with a larger capacitance (Farads).

Replacing a capacitor
The voltage rating has to be at least as high as the cap you want to replace, but it can also be higher. (If you know the voltage between the two pins on the board and it is less than 35V you can also use a cap with a lower voltage rating, e.g. the volatge on the board is 20V than you could also use a cap with 25V voltage rating).
