0.100" Pitch, 5-Position Right-Angle Header for MTA-100 IDC Mating
The 3-644457-5: This 5-position unshrouded header from the MTA-100 series mates with the standard 0.100-inch pitch IDC receptacle — the same footprint used across TE's MTA-100 wire-to-board family.
Right-Angle Through-Hole: Board-Edge Routing and Solder Reliability
This is the standard choice for board-edge I/O where the enclosure wall is close to the connector. The solder tail is 0.110" (2.79 mm) long — long enough to form a reliable fillet through a standard 0.062" board. The square pin geometry provides a consistent solder joint and resists rotation during wave soldering. This low profile keeps the connector body compact and leaves clearance for adjacent components.
