It uses machined copper alloy contacts rated 5A per circuit, with a steel shell finished in tin plating. ## Shell Size and Mating Compatibility This receptacle uses shell size 1, connector layout DE (E), which is the standard DB-9 footprint. It mates with any standard 9-position D-Sub plug (male) having the same shell size and layout. The housing includes an unthreaded flange for mounting with screws or jack-screws — the mating plug typically carries the threaded insert or screw-lock hardware. The 2-row arrangement with 9 contacts follows the classic DB-9 pinout: 5 pins in the top row, 4 in the bottom. ## Through-Hole Solder Termination This gives a mechanically robust joint compared to surface-mount, important for a connector that sees mating/unmating forces. The machined contact form provides consistent solder-wetting and a reliable gas-tight joint after reflow or hand-soldering.","metaTitle":"Molex 1731091172 FCT D-Sub Receptacle, 9-Position, 5A","metaDescription":"Molex 1731091172 FCT D-Sub receptacle, 9 positions, 5A, solder termination, through-hole, UL94 V-0.
