The value at 25°C and 100kHz is commonly quoted, with a formula provided to calculate the value at the operating frequency.

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).
