* The second, an Adam Tech (never heard of these guys) part. Must be a brand new part on the market. Especially since mouser has them marked as new and 8wk factory lead time, and minimum qty of 1000. I should probably add to my spec the maximum "minimum order" should be like 5 or 10... Hmm, looking further, that part number doesn't even show in the catalog linked as the datasheet. Must be brand-spanking-new.
That's a receptacle (female). I've found theses, but what I was asking about is a plug (male).
Have you tried contacting any manufacturers?
