The 0.156\" (3.96mm) pitch is the standard spacing for the MTA-156 series, matching the pin header on the board. This is a free-hanging, single-row housing with a closed end — the wire stops at the back wall so you get consistent insertion depth every time. The locking ramp on top grabs the header latch and holds against cable strain; you hear it click when it seats. IDC termination pierces the wire insulation as the cover is pressed down — no separate crimp terminal or tool. The 22 AWG wire gauge is the only size listed for this variant. ## Contact Finish — Thick Tin for Low-Cycle Duty ## Mating Connector — What It Plugs Into A common mating header is TE 644456-3 (straight, tin) or 644461-3 (right-angle, tin). No other series shares this latch geometry — don't try to force it into a non-MTA-156 header.","metaTitle":"TE 3-644371-3 MTA-156 Receptacle, 3 Pos, IDC, 22 AWG","metaDescription":"TE 3-644371-3 MTA-156 receptacle, 3 positions, 0.156\" pitch, IDC termination for 22 AWG discrete or ribbon cable, tin contacts, locking ramp.
