Can I replace a capacitor with a lower? There are two answers. It is possible if you have the necessary skills and tools. It is safe. If you put a higher voltage than the maximum you could see your cap explode, that’s the only rating that matters for safety.
Is it OK to replace a capacitor with lower voltage rating? 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.
Can I use a smaller microfarad capacitor? Under sized (smaller than needed microfarad) will result in longer starting times, and if excessively undersized no starting. Larger than needed microfarad values will not cause much of any problems (especially for a start capacitor).
Can I use a different UF capacitor? There is a maximum of +10% tolerance in microfarad rating on replacement start capacitors, but exact run capacitors must be replaced. Voltage rating must always be the same or greater than original capacitor whether it is a start or run capacitor.
