[sdiy] capacitor voltage ratings

[Rafael_Cohen at prusec.com]

Hey everyone,
Yet another newbie question here.
I am curious about the voltage ratings on capacitors.  I was buying some
from www.Jameco.com earlier today and I was trying to figure out the
dirrefences in price and the differences between the different products....
If I have a previous circuit that I am trying to copy and the old one uses
100uF caps at 16V can I substitute 25V?  50V?  Why are some cheaper than
others?

Also, in the CGS parts lists (soon to build my Steiner VCF), some of the
modules list caps at a particular voltage.  If I am substituting, is it
irrelevant as long as it is a higher value than the given specifications?

Thanks for any info...
