Substituting capacitors with different voltage ratings?

Leakage might be less, a good thing.

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?

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.
