A closed end blocks wire push-through past the last contact, and the polarizing key prevents the receptacle from being inserted backwards into the matching header. This connector is built for permanent or semi-permanent harness assemblies where the wire-to-board connection is made once and left mated. ## What Mates with This MTA-156 Receptacle The 3-643817-5 mates with any MTA-156 pin header of the same 0.156\" (3.96mm) pitch and 5 positions. The header side is typically a vertical or right-angle through-hole pin header from the same MTA-156 family — the receptacle's IDC contacts wipe against the header pins and the locking ramp snaps over the header's latch surface. No separate crimp terminal is needed on the wire side; the IDC slot cuts through the insulation and grips the conductor when the cover is pressed down. Because the connector uses IDC termination, the wire preparation is simple: cut the 18 AWG discrete or ribbon cable to length, align it in the slot, and press the cover closed with a hand tool or arbor press.","metaTitle":"TE 3-643817-5 MTA-156 Receptacle, 5 Pos, IDC, 18 AWG, Tin","metaDescription":"TE Connectivity MTA-156 receptacle, 5 positions, 0.156\" (3.96mm) pitch, IDC termination for 18 AWG discrete or ribbon cable.
