I have made a mistake on a recent schematic for PCB production

I now need a 4 pin npn optocoupler with pins 3/4 reversed from the standard configuration of the emitter on P3 and collector on P4.

I need the reverse emitter on P4 and collector on P3 to save my pcb's !! A right PITA

Any ideas on a part number/model?

Specs not critical but pinout is Looking through farnell didn't give any obvious clues.

Shame you didn't mess up both sides, you could just mount them on the bottom. Maybe a AC line monitor opto. I found these, but they appear to only be surface mount (maybe need a daughter board).

This one is through hole

Wrong way round on the output those Greg, I need pin 3/4 reversed.

Solder them in upside-down, that is mount the optos on the underside of the pcb and solder the legs from the top. That will reverse the output pins and with the dual led inputs it will still work fine. It will look a bit strange, just claim it is a design feature.

Brilliant idea Greg

Cock ups are never welcome, but it's comforting to know other people make them too!

Sometimes I worry about these "brilliant ideas", maybe I've had too much practice sorting out my own cockups.
