The Molex MX150 1600733105 is a 3-circuit, single-row receptacle housing from the MX150 160073 series, designed for sealed wire-to-wire or wire-to-board interconnects in harsh environments. The 4.50 mm pitch gives enough spacing for the 14 AWG to 18 AWG wire range these housings typically accept, keeping creepage clearances intact for 12 V and 24 V vehicle electrical systems. The housing is black polyamide 6, glass-filled, with a UL94 V-0 flame rating implied by the material choice — standard for underhood and industrial enclosures where a fire stop is required.
The 4.50 mm Pitch and Sealed Build
At 4.50 mm pitch, this is a mid-pitch sealed connector. The pitch is a direct match for the MX150 male header footprint, so the board layout is fixed by this dimension. The sealed construction, combined with the CPA latch, means this housing is meant for applications where a partial mate or a back-out under vibration is unacceptable.
The terminal part number is not listed here, but it is the standard MX150 female socket for 14-18 AWG wire. For a BOM line, this means two line items: one for the housing (1600733105) and one for the terminals (typically sold in reel or strip quantities). The housing's free-hanging (in-line) mounting type means it is used as a cable-to-cable or cable-to-board connector, not a panel-mount or PCB-mount part.
