MTA-156 IDC Receptacle, 11 Circuits, 0.156" Pitch — Harness Designer's Notes
The TE Connectivity MTA-156 4-640601-1 is an 11-position IDC receptacle in the MTA-156 series, designed for mass-termination of 22 AWG discrete or ribbon cable. The 0.156" (3.96mm) pitch sets the wire-to-wire spacing, matching the standard MTA-156 header footprint. The red housing colour is a factory visual cue — it doesn't affect fit, but it helps identify the 11-circuit variant on a populated harness board.
Sourcing and Lifecycle — Active, RoHS Compliant
The 4-640601-1 is listed as Active on the lifecycle record and is RoHS Compliant. For a BOM line that needs this exact 11-position IDC receptacle, it's a straightforward source — no cross-reference hunt required.
Mating and Installation — What It Connects To
This receptacle mates with the MTA-156 header family — a 0.156" pitch, single-row, pin header. The feed-through feature allows daisy-chaining: the IDC slot passes the wire through so the same cable can continue to another connector in the harness. Wire gauge is fixed at 22 AWG for this part — the IDC slot geometry is sized for that conductor diameter. Using a different gauge risks an unreliable termination or a loose fit in the slot.
