The 0.156\" (3.96mm) pitch matches the standard MTA-156 ribbon cable conductor spacing — pitch has to match the ribbon, or the IDC slots bite between conductors instead of onto them. The red housing carries a closed end and a polarizing key, so the connector seats only one way against the mating header. ## IDC Termination — 22 AWG, Tin Contacts, 80.0µin Plating Tin is cost-effective for high-volume, low-remate applications; if the harness sees repeated disconnect/reconnect in the field, a gold-plated variant would hold up longer. The locking ramp adds vibration resistance once mated.","metaTitle":"TE MTA-156 3-643819-9, 9-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 3-643819-9 9-position IDC receptacle, 0.156\" pitch, tin contacts, locking ramp.
