Low Profile 1/4" Panel Mount Jacks

[Rpschultz13]

I've been buying these Low Profile jacks for years, love them. I didn't realize until recently there are 2 flavors: Mono and Stereo. Recently for the Q-tune project, we settled on the Mono version... because it's switched. With nothing plugged in, it will ground the input which prevents Op Amp oscillations in certain circumstances. The ONLY place I can find these is Tayda. Amplified Parts has the stereo version but not mono-switched. I really only need it for the input, either one will work for the output jack. You can tell the difference between the two flavors because the stereo version has the ring/tip aligned with each other, while the mono version they are slightly offset.

If you know of a supplier that has the Mono version, please let me know.

Just for clarity- these are pcb rather than panel mount, correct? The title says one but shows another- that being said, I can certainly see using these off-pcb.

Yeah Tayda and Amplified Parts call them panel mount, but I use them as PCB mount. I suppose either.

AliExpress. I use the stereo versions for the I/O PCB in all of my builds, but most of the same vendors sell the mono ones, too. I stocked up before the tariffs hit, so my info might be out of date, but as February you could get these from a number of different AliExpress vendors for about 50¢ each.

I’ve looked in Ali. If you could provide a link to the mono version, I’d appreciate it

I get mine from Daier via AliExpress. It's a PJ-651A. If you buy enough from them, you get a rep reaching out

Digging around for 1/2 hour, I still can't find them for less than $1 each in bulk. Tayda is $0.55.
