The 644694-3: The kinked solder tails (0.110" post length) provide mechanical retention during wave soldering and resist pull-out from cable strain.
This header mates with MTA-100 series IDC receptacles and crimp-style housings that accept 0.100" pitch contacts. Termination is through-hole solder: the kinked pins self-locate in the plated holes and hold during wave or hand solder.
Yes, the 644694-3 is classified as Obsolete by TE Connectivity. No official replacement part number is listed.
Yes, the 644694-3 is an MTA-100 series header and mates with MTA-100 IDC receptacles and crimp housings that use 0.100" (2.54mm) pitch contacts. The unshrouded design means no keying — ensure the receptacle latch orientation matches the board layout.
