As long as capacitance is the same and the voltage is equal to or greater you should be able to use anything you have. In the past paper was used for larger values and mica or ceramic disc for smaller values. Lots of different voltage ratings were used because higher voltage ratings made the cap so much larger physically that using a lower voltage rating, when possible, meant the component would be much smaller. With the insulation materials used in todays caps, any 2 caps of equal value, todays cap will be smaller than the counterpart of yesteryear.
