The gray housing is free-hanging (inline), so this receptacle sits in the harness and mates to a PCB-mounted header.
IDC Termination — Line-Feed Fit for Harness Builds
For a harness builder, that translates to one less process step and consistent termination depth across the 5 positions. The single-row layout keeps the cable exit inline with the mating header, which simplifies routing in tight enclosures. The 'Mates to PCB' feature confirms this receptacle is intended to plug into a board-mounted pin header — not a panel-mount or another inline connector. That makes the board-side header the critical mating half to source alongside this part.
The 5-position count at 0.098" (2.50mm) pitch is the primary footprint constraint. A 6-position header will not fit this receptacle, and a 4-position header leaves one contact unconnected. The single-row layout means the mating header must also be single-row, 5 positions, with 2.50mm pitch.
