The 0.156\" (3.96mm) pitch is wider than the common 0.100\" IDC format, giving more room per wire for hand-loading or automated harness assembly. The closed-end housing prevents the wire from pushing through the back of the connector during insertion — a common rework cause in IDC builds. A polarizing key on the housing ensures the mating header is oriented correctly before the locking ramp engages. ## Tin Plating at 80.0µin — Built for IDC Wipe The contact finish is tin at 80.0µin (2.03µm) thickness. For an IDC termination, the insulation-displacement slot wipes the tin surface on insertion. ## Active Production, ROHS3 — No LTB Risk The 3-643819-3 carries an Active lifecycle status with ROHS3 compliance. There is no last-time-buy notice or phase-out date on record. For a BOM line, this means the part can be specified into new designs without an obsolescence watch. Compliance documentation covers the current RoHS exemption set (ROHS3).","metaTitle":"TE MTA-156 3-643819-3, 3-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE MTA-156 3-643819-3 3-position IDC receptacle, 0.156\" pitch, tin 80µin plating, locking ramp.
