The Molex 0447691601 is a 16-circuit receptacle from the Micro-Fit 3.0 BMI 44769 series, designed for board-to-board or cable-to-board interconnects in general-purpose and telecommunications equipment. It's a dual-row, through-hole solder connector with a 0.118" (3.00 mm) mating pitch and a 0.118" (3.00 mm) row spacing — the footprint matches any standard Micro-Fit 3.0 layout. Rated 5 A per circuit at 250 VAC, with tin-plated phosphor bronze contacts — 100.0 µin (2.54 µm) of tin on both the mating surface and the solder post. The tin finish limits this to moderate mating-cycle duty; it's not a high-cycle field-service connector, but it's cost-effective for one-time assembly or occasional rework. The 16.86 mm mated stack height is set, so if you're stacking boards, that z-height is fixed by the BMI (Blind Mating Interface) design — no height-adjust options in this variant. Blind mating and integrated board guides are built into the housing — the connector self-aligns during mate, which helps in blind-mount or panel-access scenarios where you can't see the interface. The push-pull fastening type keeps insertion and extraction simple without needing screws or latches.
This is the receptacle (female socket side) — it mates with the matching Micro-Fit 3.0 BMI plug header, typically the Molex 043045 series or 044770 series headers in the same 16-circuit, 3.00 mm pitch. The female socket contacts accept the square pin from the header. Termination is through-hole solder only — no press-fit or surface-mount option on this order code.
