76-Position Right-Angle Header for High-Density Board-to-Wire
The 3.50mm mating pitch and 5.20mm row spacing define the PCB footprint — a dense but routable layout for a 76-circuit interconnect. The shrouded 4-wall housing with latch holder fastening provides vibration-resistant retention, a key feature for automotive and general-purpose environments where the mated pair must stay locked under shock and movement.
Footprint Fit and Mating Half Check
The 0.138" (3.50mm) pitch and 0.205" (5.20mm) row spacing are the critical dimensions for PCB layout — a 76-position dual-row header at this pitch requires a 38-pin-per-row footprint with staggered or inline pads depending on the mating receptacle. The contact length on the mating side is 0.280" (7.11mm) and the post length is 0.157" (4.00mm) — these dimensions define the mating depth and solder tail protrusion below the board. The mounting flange adds mechanical stability during assembly and in-service vibration. For a given harness, confirm the terminal current rating at the operating temperature.
The base product number is 174915; the -6 suffix indicates a specific configuration (76 positions, right-angle, gray, tin). Verify the mating half — a 76-position Multi-Lock receptacle with 3.50mm pitch and latch holder compatibility.
