Yes, a capacitor with a higher voltage rating can replace a lower voltage capacitor of the same capacitance. A higher voltage capacitor simply means that it can be charged up to a higher voltage level. So, using it won’t change the performance of the circuit.
Anyway thank you You absolutely should not replace an electrolytic capacitor with one of lower voltage rating. That would only be okay if the system was designed with a lot of overhead, but for high-volume devices like PC power supplies that's very unlikely.
No, it is not necessary to replace a capacitor with an exact replacement. In many cases, replacing a capacitor with a higher or lower value can make the circuit perform differently or better than before. However, keep in mind that increasing the capacitance may affect the resonant frequency of LC circuits and also increase their current draw.
The rule of thumb is if the capacitor value plays a part in things like tuning or timing of a circuit, it is best to not lower the capacitance. Sure, lowering the uf by a little might not have considerable effects but, these small changes will add up in the end. Other considerations when replacing a capacitor with a lower uf 00
So, if you decide to replace a capacitor with a lower uf one, make sure that the new capacitor has the same voltage rating of the one you are replacing or is larger. The main construction of a capacitor involves two electrical conductors (plates), separated by an insulating material known as a Dielectric .
When designing a circuit, capacitors are chosen with voltage ratings that match or are little larger than the voltages expected in the circuit. The rule of thumb is to select capacitors with voltage ratings higher than those expected in the circuit as a buffer.

Replacing Capacitors: Which Values to Follow and Which Ones
To replace a part with a different part (including capacitors), you really have to reverse engineer the circuit to some extent, to determine the requirements for the part. Among others, these requirements could include voltage, current, power, value tolerance, physical dimensions, footprint, pinout, temperature, humidity,

Solution Guide: Replacing Electrolytic Capacitor with MLCC, …
Replacing electrolytic capacitors with MLCCs ofers various benefits such as space reduction due to smaller size and lower profile, reduced ripple voltage due to low ESR, and improved reliability due to reduced self-heating. On the other hand, low ESR, which is an advantage of MLCCs, can sometimes lead to abnormal oscillation or anti-resonance.

Replacing Electrolytic Capacitors In Vintage Electronic Gear
A can capacitor from CE Manufacturing with four sections (40/20/20/20) can cost $40.90. A similar JJ can capacitor costs $16.95.

Capacitor
In some capacitors where dangerous voltages and energies exist, such as in flashtubes, television sets, microwave ovens and defibrillators, the dielectric absorption can recharge the capacitor to hazardous voltages after it has been shorted or discharged. Any capacitor containing over 10 joules of energy is generally considered hazardous, while 50 joules or higher is potentially …
