8-Position Micro Quadlok Receptacle Housing for Wire-to-Board Harnesses
The TE Connectivity 1745000-3 is an 8-circuit receptacle housing from the Micro Quadlok series, designed for wire-to-board interconnect in automotive and industrial harness assemblies. The housing uses a latch lock for positive retention — you will hear it click when the plug seats fully against the header, which matters in a vehicle or machine where vibration can work a friction-fit loose over time. The glass-filled PA66 body handles the -25°C to 85°C range typical of under-hood and cabinet environments, and the black colour is standard for the series.
Contacts Are Ordered Separately — Plan Your BOM Line
The 1745000-3 ships as an empty housing — the note on the line is "Contacts Not Included". That means the female socket terminals must be ordered as a separate line item. For the Micro Quadlok series, the mating crimp terminal is typically the TE 1745010-1 (for 20-22 AWG) or the 1745010-2 (for 18-20 AWG), depending on your wire gauge. If you are filling a BOM, add the terminal quantity (8 per housing) and the crimp tooling — the standard TE hand crimper or a semi-automatic press with the correct applicator. The housing alone is just the shell; the electrical path starts with the terminal.
Mating Half and Harness Assembly
The latch lock on the housing engages with the ramp on the header shroud. For a field-service or harness-build scenario, the free-hanging (in-line) mounting means you terminate the wires first, then click the housing onto the board-mounted header. The two-row arrangement keeps the assembly compact — 8 circuits in a roughly 10mm-wide footprint.
