The 3-644457-2: It mates with standard 0.100-inch pitch IDC receptacles or crimp housings for board-to-wire connections.
At 2 positions, this is the smallest circuit count in the MTA-100 family — often used for a single power pair or signal jumper where only two connections are needed. Compared to the 1-292164-1 from TE's CT series, that part uses a tighter 0.079-inch (2.00mm) pitch and has a shrouded 4-wall housing with a detent lock.
It is ROHS3 compliant.
Yes, the 3-644457-2 is ROHS3 compliant per TE Connectivity's listing.
