The glass-filled nylon (PA66) insulator handles the -40°C to 100°C operating range typical of under-hood and industrial cabinet environments. The 22-position count and dual-row layout match the footprint of a corresponding 22-position header, so the BOM line check is straightforward: confirm the mating header has 22 circuits in two rows.
The 2-1419158-8 mates with a 22-position, dual-row header that shares the same locking ramp interface. The crimp termination accepts male pin contacts — the exact contact part number depends on the wire gauge and plating grade (tin vs gold) your application requires. This gives the assembly a vibration-resistant lock that won't back out under engine or machinery shake — important for harnesses routed near moving parts.
