BD139 and TIP41 have different leg , you should check it before replace, cannot just replace like usual, check it on datasheet before do that

Plastic film with either metalised layer or metal foil.

Check the pcb layout, it does look like an electrolytic.

But it's an input cap so any non-polar should work.

Default Any voltage will fit..use the one you find

Voltage in the input is just a couple of volts..do not worry and use the one you have.

regards,

Carlos
