Looking for panel mount transistor sockets - or other ideas

[Kevin Mitchell]

Sure there are plenty of creative alternatives but I'm a stubborn dude with a vision 

I was trying to find a good panel mount socket to use for a transistor tester (matching VBE). I have my circuit and wanted to box it up. After looking around I had found a page for these which are no longer available;


I can maybe find some from some iffy Chinese sites but I'm not much of a gambler - and they're expensive. So I'm looking for other sources or similar approaches for panel mount sockets.

Alternatively I could and probably will redesign the board for easy to obtain parts and offer them to the public. But right now I have crazy thoughts about an oldschool tester with a mounted center 0 mv meter. Would make a cool Rev.1 project

zif socket is cheaper

How many do you need?

I have a few that I found a long time ago at a surplus store.  They are 3 pin....

Round, with no mounting flange.  You would just drill a hole and glue them in.

Yeah.. I would bet Tayda may have a Ziff....

I know zifs are cheaper but I'm a difficult man doing things the hard way 

If I were to use a zif I would try for a 16 pin which tayda does not stock. No big deal. Half for testing NPN pairs and the other half for PNP.

If I can't find these old panel mount sockets I'll redraw my circuit sooner rather than later. Thinking of a module made up of two stacked PCBs rather than housing the circuit. But that throws out my old school home-brew tester idea.

I know I can find these sockets somewhere - just not without risking getting scammed. Looking for a TO-220-4 or TO-92-4 sockets with mounting wings proves to not be an easy task.

To house my circuit I'd just need two. Most transistors I use are EBC anyhow so I could neglect the 4th pin for this one.
Are they TO-220 or TO-92?

TO-92.

I happen to have 2 with larger holes, that would better work for you.

Thank you!
Shoot me a photo of em' when you have a chance.

Give me a few min....

Ah those would be perfect! Press-in too I believe. Found something similar on ebay but it was an assorted lot. Could probably find press-nuts to secure them.

PM me for deal/trade.

Thanks, Mark!

Just PM your address and I will drop them in the mail to you tomorrow.

Panel mount 3 or 4 pin with mounting flange can be found in old Tektronix test equipment.

I've seen this thread but couldn't figure out where to find them!

Would have been Digikey or Mouser, most likely the former, i'll see what i can dig up.

My order histories don't go back far enough at either to find out for certain but here's some 3.5mm pitch from Digikey, there are 2.5mm's at Digikey and Mouser but none exactly like the ones i used.
