The housing you need — but don't forget the terminals
The 1-172159-9: It carries a 0.163" (4.14mm) pitch with matching 0.163" row spacing, making it a compact but serviceable wire-to-board or wire-to-wire interconnect for moderate-current circuits. The critical note on this listing: contacts are not included. The housing accepts both, so pick the terminal that mates with your existing header or receptacle half.
What the 4.14mm pitch means for your build
The 0.163" (4.14mm) pitch is wider than typical signal connectors — it's sized for the Mini-Universal MATE-N-LOK terminal family that handles up to around 9.5A per circuit in the right wire gauge. That pitch gives you enough room for the crimp barrel and the locking ramp without crowding the panel cutout. For a 4-position, 2-row layout, the overall housing width stays under 0.5", so it fits in tight panel spaces. The snap-in panel mount means the housing locks into a rectangular cutout with integral barbs — no screws or brackets. Confirm the panel thickness and cutout dimensions from the TE product drawing before committing the BOM; the snap retention depends on the panel being within the specified range.
For harnesses routed near engines, pumps, or conveyor drives, that latch keeps the connection closed without needing a bolt or clip.
