Big caps.

I ordered some film capacitors from mouser. Some are really big. I'm assuming they'll work since the values are the same as far as I can tell, although they won't fit on the PCB I got from the fine folks at Madbean. The question is, how do I avoid such an issue in the future? I didn't notice anything while ordering that mentioned size.
Also, does color signify anything? Some were yellow. And one looked like a miniature soda can.
I think I'll stick to Mammoth and Small Bear for now...

Higher voltage rating = larger cap size. Try to stay in the 25 to 50v range.

if its the green caps then anything from 100nf will be fairly large. Stick to the box film caps, they come in small sizes and make sure they're 5mm pitch.

With film capacitors you want lead spacing (also shorthand l/s) = 5mm or 5.08mm. Usually the voltage is 50V, 63V, 100V.

Early on I ordered a handful of 1000V orange film power caps. Live and learn.
