15-Circuit, 3-Row Receptacle Housing for Power Harnesses
The Molex 0019091159 is a 15-position receptacle housing from the 3191 series, arranged in three rows on a 6.71 mm pitch. The wide pitch and triple-row layout suit multi-wire power distribution harnesses where each circuit carries a separate load — think appliance internal wiring, industrial control cabinets, or automotive body harnesses.
The 0.264" (6.71 mm) pitch is the same in both directions — between adjacent positions in a row and between rows. That gives you a roughly square cavity grid, so the housing footprint is about 20 mm wide by 13 mm tall. For a harness builder, that pitch leaves enough room between cavities to run 14-18 AWG wire without the insulation crowding the adjacent terminal. The 3-row, 15-position count means you can route five circuits per row, which keeps the wire bundle organized at the connector face.

Mating Half and Locking
The lock provides positive retention in applications where the harness sees vibration or occasional tugging. For a field-service technician, the latch is easy to depress with a screwdriver tip to unmate the pair without prying on the housing body.
