Hi all,

Given that NOS TF caps seem to be increasingly hard to come by, is there
a modern equivalent type that can satisfactorily replace them with a
similar footprint & pinout? I'm specifically interested in the 250V rated
types found in old 'scope smps.

thanks

Mpfffff.... Within very basic parameters and manufacturing standards, a cap is a cap is a cap.

Apart from the mystery, smoke, mirrors and hokum surrounding "bumble-bee/tropical fish" caps and so forth, about any modern polyester film cap of decent manufacture is its *actually functional* equivalent.

Keeping in mind that the fuzz-box crowd is really looking for an R/C network rather than a cap, despite the schematic, why these too-often leaky caps are sought after becomes easier to explain. I have a neighbor down the block for whom I save my pulls and leakers of this nature. I try to tell him that all he really wants is a 1 or 2 meg resistor parallel to an 0.047 cap - but he wants it all in one package complete with a bakelite case.
