5-Position Single-Row Plug Housing for 2.50mm Pitch Harnesses
The free-hanging (in-line) mounting style suits it for harness drops where a panel-mount or board-mount receptacle is the mating half.
Crimp Housing — Contacts Ordered Separately
This is standard for the Grace Inertia GIC series — the housing and terminal are line items on the BOM, not a pre-loaded assembly. Plan for a separate terminal order code and a crimp tool qualified for 2.50mm-pitch contacts. The latch lock fastening provides a retention force that resists un-mating from cable tug or vibration. In a harness build, the red housing colour serves as a visual key — if the line has multiple GIC connectors at different positions, the red shell flags this as the 5-way variant.
Comparison: 5-Position vs 6-Position GIC Plug Housing (1-1376477-6)
The closest same-series peer is the 1-1376477-6, a 6-position Grace Inertia GIC plug housing at the same 0.098" (2.50mm) pitch, same red PA66 material, same latch lock, and same crimp termination. The only decision-relevant difference is position count: 5 positions on the 5-1971793-3 versus 6 positions on the 1-1376477-6.
