|The only time replacing electrolytic capacitors with ones of a higher voltage rating is unwise is if the voltage difference is extreme. For example if a 1V capacitor was replaced with a 100V one then it might not be able to "form" correctly at the lower voltage. In the instance quoted it should be fine - there is plenty of leeway in this. |
Obviously you never replace with one of a lower voltage rating unless you are certain the actual voltage will always stay below that of the capacitor rating.
Always pop back and let us know the outcome - thanks
