I highly recommend you get exact replacement parts including type, voltage, and ESR. You can use a cap with higher voltage rating and lower ESR. You will also have to make sure the pin diameter isn't too large and the width between the pins is correct.

The last time I had to do this (about 6 months ago) I got exact replacement parts from Mouser Electronics.
