Substituting capacitors with different voltage ratings?

[Tristar]

I'm starting out building a simple 555 tester circuit before I move on to
the more complicated bike timer. I was wondering what the possible effect
on using a 1uF cap with 50 volt rating instead of the suggested 1uF 16
Volt?

Leakage might be less, a good thing.

Electrically you can substitute with a higher spec. However, if you are
using a printed circuit board the 50 V type may not fit mechanically,
since it will be larger than a 16 V.

You also have to be careful about substutions in circuits requiring
low ESR cpacitors.

It'd cost more, be bigger, and possibly last a little longer.

With capacitors the voltage rating is the maximum volts it can handle.
so a 50V capacitor is more rugged but otherwise electrically identical to
a 16V part.
