Default Small Capacitors: What Numbers Critical?

Per dave:

Is this an electrolytic? Polarized?


I can't find any indication of polarity.

I'm not sure what constitutes electrolytic, but when they failed a
brownish goo leaked out and solidified.

Here are a couple of pix:

That 'leaked goo' is just glue that the manufacturer has used to stick a
radial cap down to the PCB so that it 'pretends' to be an axial type. What
checks have you done to establish that the cap is faulty ? ESR ? This is the
main check that you always have to do on any suspect electrolytics. Value ?
Usually of secondary consideration to ESR. Physically short circuit ?

If you are basing your belief that the cap is faulty on what you perceived
to be something that had leaked out from within, then there's a very good
chance that you are mistaken.
