The 1718570005: This is a 5-position single-row header from the Molex KK254 series, 0.100" (2.54mm) pitch, through-hole right-angle mounting. That matters on a harness that sees vehicle or machine movement.
The 60 µin layer gives enough wear margin for occasional disconnect-reconnect in service.
Status is Active. ROHS3 compliant.
This header mates with a KK254 crimp receptacle housing (single-row, 5-circuit) using the matching crimp terminals. The friction lock on the header engages the receptacle's locking ramp. Confirm the receptacle part number against your harness assembly.
