The 1722872302: This is a 2-position, single-row header on a 0.138" (3.50mm) pitch — the narrow pitch saves board space while keeping enough clearance for 400V rated circuits. This is a vibration-resistant mate, not a friction-only fit.
The post is tin-plated (60.0µin), which is standard for solder joints and avoids gold embrittlement in the solder fillet.
This header mates with a Molex Ultra-Fit receptacle housing that accepts the matching crimp terminal. The latch holder on the header engages with the receptacle's locking feature. Confirm the circuit count and wire gauge with the receptacle datasheet.
