The housing ships empty — the AMPMODU Mod IV crimp socket terminal is a separate line item. Ordering the 925370-8 without the matching contact means the harness cannot be assembled. The correct terminal is the TE AMPMODU IV female crimp socket, typically ordered in bulk reels or strip form for the crimp press.
Both the pitch and the row spacing are 0.100" (2.54mm). That is the standard AMPMODU Mod IV grid, so the 925370-8 mates with any 2x8 pin header on that same 0.100" x 0.100" matrix. The dual-row layout gives 16 circuits in a compact width — about 0.500" across the housing body — which fits a standard 0.100" header footprint on the PCB. No special keep-out or routing clearance beyond the header body is needed.
