What This Connector Is
The Molex 0447690802 is an 8-position, dual-row female receptacle in the Micro-Fit 3.0 BMI series, rated 5 A per circuit at 250VAC and designed for board-to-board or cable interconnect with blind-mating capability and integral board guides.
Plating, Fastening, and Stack Height
Mating-side contacts carry 15.0 µin (0.38 µm) gold over the full position count; the solder-post side is 100.0 µin (2.54 µm) tin — the differential plating grades the signal side for repeated mating cycles while the post handles solder-heat exposure without dissolution. Push-pull fastening means the pair locks without thumbscrews — the blind-mate geometry and board guides guide the two halves together under visual-occluded conditions, common in telecom shelf assemblies and stacked PCB modules where the top board is not directly accessible. The mated stack height is 16.86 mm with a 13.60 mm insulation body above the PCB plane; the 0.134-inch (3.40 mm) post length is compatible with standard through-hole padstack depths for this series.
Materials and Environment
The insulator body is glass-filled liquid crystal polymer (LCP), black, rated UL94 V-0 — suited for the operating envelope of -40°C to 105°C and the general-purpose and telecommunications environments the listing names. Contacts are phosphor bronze; square contact shape distributes uniform spring force across the mating interface and resists lateral deflection under vibration once seated.
Sourcing and BOM Fit
Listed Active with no official successor or cross-reference. The base product number 044769 anchors the full family — any 8-position BMI variant shares the same footprint; confirm the mating half's push-pull locking style before committing.
