7-Position IDC Receptacle for MTA-156 Harnesses
The closed-end design with a polarizing key prevents mis-mating and blocks wire push-through during assembly — a practical detail for harness shops running repeat builds.
This receptacle terminates 22 AWG wire via IDC — no stripping, no crimping, just a one-step press into the slot. Tin contacts are well-suited for low-cycle-count, cost-sensitive harnesses; the thick plating helps maintain contact integrity in mildly humid environments. The red housing color aids visual line identification in multi-wire harness assemblies, reducing the chance of a wire being landed in the wrong position during manual or semi-automated build.
MTA-156 Compatibility and Cross-Shop
This receptacle mates with any standard MTA-156 header at the same 0.156" pitch. The 7-position count is the key BOM match — the 6-position sibling (3-644463-6) shares the same pitch, termination, and wire gauge but one fewer circuit. If your harness calls for 7 circuits, this is the correct IDC receptacle; the 6-position variant won't fit the header.
