and now, graphical - how to brute force push Cinemag in place of Jensen
under condition that Cinemag pins aren't thicker than Jensen - I don't have PC mount Jensen for reference and datasheets are not helping, so can't tell for sure
if you want other way - to push brute force Jensen in place of Cinemag it is straightforward ( Jensen having less pins than Cinemag), you just need to drill a hole for Jensen pin 1
in both cases - do not try to bend critical pin (instead of drilling hole for), or you'll cry - if not right away, then later for sure

I have just ordered a pair of Cinemag CMOQ-4HPC. Once I receive them I will measure the pins' dimensions and let you know.
Hey ZM, in your zipped file in post #160, my gerber viewer shows the transformer pin lands but no pcb tracks connecting them - am I missing something?
Datasheets show the Jensen pins as being 0.025" square with recommended drill size of 0.04" The Cinemag pins are showing as 0.026' square - so basically the same size.
OK, now I see, the tracks showing on grimbergs pcb had me baffled. If you have 1mm (0.04") drill hole size in your design ZM, that would be OK. Or 1.1mm as grimberg has.
I have both Jensen and CineMag transformers on hand. They both use square pins. The Jensen datasheet recommends 0.040 diameter PC holes. Pins are 0.025 square.
there is no problem with pad holes Dia for adapter board, it was slight dilemma for Brute Force approach
This may sound odd - how does this board actually work as an add-on to an existing PCB? With either of the transformers installed, there is no easy way to connect signals down to the main board. Perhaps the offset holes are better suited for a daughter board. The overlapping pads are better for a PCB that supports a dual footprint.
ZM, I think there is something wrong with the zipped gerber file in post 176, using 3 different on line gerber file viwers - all show nothing.
ZM packed the gift within another gift - unpack the zip and the gerber is inside as a second zip ...
