The 0022284362: The unshrouded design means the male pins are fully exposed; it mates with standard KK254 crimp receptacles or IDC sockets, but offers no keying or polarisation, so orientation must be verified during assembly. That post length is typical for a 1.6mm-thick PCB — confirm the board thickness and solder fillet height before committing the BOM.
Tin is a cost-effective finish for low-cycle applications — expect 25–50 mating cycles before wear-through.
Flammability and Material
The housing is glass-filled nylon (PA) rated UL94 V-0 — the highest flame-retardant grade for connectors inside equipment enclosures.
