The Molex 0447692003 is a 20-position dual-row receptacle from the Micro-Fit 3.0 BMI 44769 series, designed for board-to-board or cable interconnect. Rated 5A per contact at 250VAC, with a UL94 V-0 LCP housing that takes the -40°C to 105°C operating range common to telecom and general-purpose equipment. The through-hole solder tails are 3.40mm long — enough for standard PCB thickness without protruding past the backplane. Blind-mating features and board guides are built into the housing, which helps when the connector is tucked into an enclosure corner where you can't see the alignment.
This receptacle mates with a Micro-Fit 3.0 BMI header that has 0.118" (3.00mm) pitch square pins arranged in two rows. Mated stacking height is 16.86mm, so if you're stacking boards, that's the z-height budget from one PCB to the other. All 20 positions are loaded — no option for selective population. If you're replacing or cross-referencing a 20-position Micro-Fit 3.0 receptacle, this is the BMI (Blind Mating Interface) variant with the extra alignment features.
