Can it be the same rating but different brand? I'd try putting ac dc regulator in to ebay and see what it comes up with. may not be that brand but they have them

The circuit has to be small and cheap and cannot be discussed on this forum, but thanks for the hint.

 

Hello,

It could indeed be an 4 pF capacitor, the black top denotes a 0 temperature coefficient:

As long as the ratings are similar it is not critical that the replacement cap look identical to the original. Capacitors especially don't care, because the physics is the thing.

 

Simple. Unsolder the good capacitor and measure the capacitance on a capacitance meter.
