D-Sub Receptacle, 9-Position, Vertical Solder
The Molex 1727040077 is a 9-position D-Sub receptacle from the F, FCT 172704 series, designed for standard-density DE-9 applications. It uses a two-row layout with a shell size 1 (DE, E) and a white PBT dielectric housing. The connector mounts vertically through the PCB and terminates via solder cups — a common footprint for serial, parallel, and industrial I/O interfaces where a reliable, field-serviceable connection is needed. Each contact is rated 5 A, which is typical for signal-level D-Sub circuits — enough for RS-232, RS-485, or low-power sensor lines, but not for bus-level power distribution. The gold-plated brass contacts resist corrosion through repeated mating cycles, and the steel shell with tin plating provides basic EMI shielding when mated to a conductive hood. The unthreaded housing/shell flange accepts standard D-Sub slide-locks or screw-lock hardware for retention against vibration.
The unthreaded flange accepts standard D-Sub hardware — 4-40 threaded inserts or slide-locks — to secure the mated pair.
