Contacts are not included. The 3191 series accepts both male and female crimp contacts, so confirm which gender your mating half requires and add the terminals to the BOM line. A common sourcing miss is landing only the housing and stopping the build because the terminals are on a separate PO. ## Pitch and Footprint — Why 6.71 mm Matters The 0.264\" (6.71 mm) pitch is wide compared to a typical 2.54 mm or 3.00 mm connector. That means the board-side footprint (if used with a PCB header) has generous clearance between pads, which simplifies routing and allows thicker traces for power circuits. The trade-off is physical size — a 12-position, 3-row plug at this pitch occupies more board edge than a denser alternative. The row spacing is the same 0.264\" (6.71 mm), so the contact grid is square.","metaTitle":"Molex 3191 0019092129 Plug Housing, 12 Pos, 6.71mm","metaDescription":"Molex 0019092129 3191 series plug housing, 12 positions, 6.71mm pitch, 3 rows, locking ramp, -40 to 105°C.
