Variation in usable capacitor ratings?
In power supplies the capacitance values are usually not critical, so
anything up to 3 times the value is probably okay, actually, a good
thing.
The voltage rating can also be higher, up to 3 times higher is
perfectly okay. If you go above that, there's a chance the capacitor
will over time lose part of it's dielectric thickness, which will
increase the capacitance, which is harmless in 98% of the cases.
