OBD-II Receptacle Housing — 16-Position D-Type Shell
The Molex 0511151601 is a 16-position receptacle housing from the OBD-II 51115 series, designed as the cable-end half of a vehicle diagnostic connector. It uses a D-type shell profile with two rows of cavities for female crimp contacts, arranged in the standard 16-pin OBD-II layout found on passenger vehicles and heavy equipment since the mid-2000s. The housing is free hanging (inline) — no panel flange or mounting ears — so it terminates the end of a harness and mates with the vehicle's panel-mounted OBD-II port. ROHS3 compliance is confirmed on the listing, so it clears EU and similar restricted-material regulations without an exemption.
This is a housing only — no contacts are included in the tray. The mating connector is the corresponding male header or plug housing from the same OBD-II 51115 series — typically a right-angle or vertical PCB-mount header that lives on the vehicle's diagnostic port board.
