The Molex 0447642203 is a 22-circuit receptacle in the Micro-Fit 3.0 BMI 44764 series, designed for board-to-board or cable-to-board interconnect.
The 3.00 mm pitch supports the 600 VAC rating. The 5 A per contact is a continuous rating at the connector body.
Mounting and assembly notes
Right-angle through-hole with a 0.155" post length — that's a standard board thickness range (0.062" to 0.093") with enough tail protruding for a solid solder joint. The insulation height of 0.402" means the mated connector stack sits about 10 mm above the board, so check your enclosure lid clearance. Blind mating and a board guide are built in, which helps when you're aligning this in a tight chassis where you can't see the connector faces. Push-pull fastening — no screw lock, but the latch on the mating plug gives a positive click.
Where it's used and what it tolerates
General-purpose and telecommunications applications are the listed targets — think internal wiring in base stations, switches, or industrial controllers where the environment is controlled but the connector sees occasional vibration. UL94 V-0 housing means it's acceptable inside equipment that requires a flame-rated enclosure. The LCP glass-filled insulator holds up to wave solder temps without distortion.
