Several years ago I disassembled an Amphenol and a MC4 connectors to
find for myself what the difference was. It came down to the cross
section of the O-ring. One brand was smaller than the other. Also the
female component that the O-ring fit into was correspondingly different.
So in one assembly the fit was too tight but both mismatched pieces
would go together with extra effort while the other the o-ring did not
fit tight enough and would snap together with normal pressure. It's been
a number of years since I did this but I doubt that either manufacturer
would alter anything that would make new connectors not compatible with
older ones.
I also recall that MC was on a tear for years, especially at trade
shows, confronting any unauthorized competitor connector maker that
implied that theirs were compatible with MC products.

Can anyone here give a brief run down on the whole Amphenol UTX (?)
defective or cross-mated connector story?
