Product details

The 0.156" (3.96mm) pitch matches the standard MTA-156 header footprint, and the single-row layout keeps the harness narrow. The closed end blocks the last cavity, so you cannot over-insert or mis-seat the cable; it also polarises the mate against an open-ended header. The yellow housing stands out in a bundle — useful when you have several MTA-156 harnesses running to the same board.

IDC Termination and Wire Gauge

No crimp tool, no solder; just a press. The wire gauge is fixed at 20 AWG, and the connector accepts either discrete wires or ribbon cable. The tin-plated contacts (80.0µin / 2.03µm thickness) are rated for the current the 20 AWG wire can carry in a low-cycle-count application; tin is not a high-mating-cycle finish, but for a one-time IDC install it is the standard choice.

Obsolete — Sourcing Reality

If your BOM calls for this exact 17-position closed-end IDC receptacle, we can still locate it; just submit an RFQ with your quantity.
