The 0.156\" (3.96 mm) pitch sets the board footprint and the receptacle spacing — it mates with standard MTA-156 crimp receptacles that use the same pitch. The single-row, shrouded-1-wall design guides the receptacle into alignment without a full shroud. ## Friction lock and tin-plated contacts The 0.650\" (16.51 mm) overall contact length gives enough standoff for the receptacle to seat fully. ## Peer comparison: 1-292164-1 vs 641991-5 The closest functional peer is the 1-292164-1 from the CT series — also a board-to-cable/wire header with a friction lock, but on a 0.079\" (2.00 mm) pitch with 11 positions all loaded. The 641991-5 runs the larger 3.96 mm pitch and only 4 loaded positions; the 1-292164-1 is a denser, fully populated alternative if your board can accommodate the tighter pitch and higher circuit count.","metaTitle":"641991-5 TE Connectivity MTA-156 Header 7 Pos 3.96 mm","metaDescription":"641991-5 TE Connectivity AMP Connectors MTA-156 header, 7 positions, 4 loaded, 0.156\" pitch, friction lock, tin-plated, active.
