9-Position D-Sub Receptacle for Standard DB-9 BOM Lines
The Molex 1731091163 is a 9-position D-sub receptacle from the FCT 173109 series, designed as the female panel-mount or PCB-mount half of a standard DE-9 interconnect. The through-hole solder termination anchors the connector firmly to the board — the right choice for applications where the mating cycle count is moderate and the connector sees board-edge strain.
Shell and Shielding — Steel, Tin Plated, DE-9 Layout
The shell material is steel with a tin plating, which gives a solid ground path and shields the signal pins from radiated EMI. The shell size is 1 (DE, E) per the standard D-sub layout, meaning the footprint and panel cutout match every standard D-sub connector on the market. The housing includes an unthreaded flange for panel mounting — you'll need a separate jack-screw or slide-lock kit if you want threaded retention.

Contact Design — Machined Signal Contacts, Copper Alloy
The contacts are machined from copper alloy — a step up from stamped contacts in terms of dimensional consistency and mating-cycle life. Machined contacts give a more uniform insertion force and better retention over repeated mates.
Through-hole mounting with solder termination gives a mechanical anchor that resists the shear force from cable strain and repeated mating cycles. The 2-row layout with 9 positions follows the standard D-sub pinout — pin 1 at the top-left when viewed from the mating face. The white color is the insulator, not the shell; the shell is steel and tin-plated.
