If you are referring to capacitance, then you would be right. However, voltage is unlimited no matter the circuit as long as you meet or exceed the working voltage that the capacitor being replaced was rated at.
Although not always in our possession, a schematic is just as important a tool as any other that we use. Exhibit A: You have a new/old piece of equipment that the same cap keeps going bad. Everything else in the circuit checks out fine, but that one cap is going kaput. Well, in all these decades of existence it is quite possible that a layman replaced the first one without paying attention to the working voltage rating. So what you find you replace based on what is marked on the casing of the wrong part and you have no reference to what in fact is right for that circuit.
Not even Ohms law calculations will bail you out without at least two known circuit values which you may not always be able to deduce without either another known to be working circuit or a schematic.
