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).

Can You Use a Larger Run Capacitor: Ultimate Answer
Install the new capacitor. To install the new capacitor, connect the two leads to the same terminals that the old capacitor was connected to. Ensure the leads are connected to the correct terminals, as connecting them to the wrong terminals could damage the motor. Reconnect the power to the motor. Once the new capacitor is installed, reconnect ...
Why Do Capacitors Fail? Capacitor failure modes and common …
A capacitor can be mechanically destroyed or may malfunction if it is not designed, manufactured, or installed to meet the vibration, shock or acceleration requirement within a particular application. Movement of the capacitor within the case can cause low I.R., shorts or opens. Fatigue in the leads or mounting brackets can also cause a ...

Does capacitor size matter?
If a capacitor can vary up to 10% of its own rating before it is condemned, then logically a cap of a different rating that falls within 10% of the rating of another cap, should be allowed as a substitution for it. ...
