Hello @ericvergara and @ChrM ,
I do not see any reason, why the connector should not fit.
The coding element is at the same place with both XG31 connectors. The difference, that @ChrM saw, is just due to perspective, I think.
The view to the contacts of the new connector does not show any kind of damage.
The PCB in slot XG31 does not show any damage, either. (Q. 3)
Looking at the picture of answer to Q. 1: I'd say that the connector is blocked at a larger angle than I would expect. I'd check that the RTB Connector is sitting perfectly in his lower bearing (cylindric form element and pivot point of RTB). It looks as if it would be blocked at the upper retainer tab element. Please check which obstacle retains the RTB from latching! I expect that one feels it, when trying to latch.
If @ChrM's or my answer helped to solve the problem, please mark the answer as "Solution"! Thank you in advance.
