I got a dual 1.42ghz MDD from eBay a while back, which arrived in OK condition, but while opening it I noticed the ethernet jack had been ripped off the board 
I was hopeful this was a mechanical issue, and there was no other damage.
First I tried to use one off a dead raspberry pi. Unfortuantely, this is completely backward (I think you could mount it on the wrong side of the board), and most available jacks have the same orientation and lands as the Pi.
After much digging, I found RJHSE5E80-ND which is an amphenol part. Any other part with the same dimensions and lands/pins will also work. MDD boards are thick and the grounds eat up heat, but after carefully cleaning the board, desoldering the remants and installing the new one, it works perfectly. Leaving this here in case anyone else has to replace the ethernet jack on an MDD (probably other G4s as well...).
