Product details

9-Position D-Sub Receptacle for Signal Interconnects

The Molex 1731091172 is a 9-position D-Sub receptacle from the F, FCT 173109 series, designed for standard-density signal interconnects. 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.

Frequently asked questions

Is 1731091172 a DB9 connector?

Yes. The shell size 1, layout DE (E) corresponds to the standard DB-9 footprint — 9 positions in a D-shaped shell. It mates with any standard 9-position D-Sub male plug.

What is the pinout of Molex 1731091172?

The pinout follows the standard DB-9 female receptacle arrangement: 5 contacts in the top row (positions 1-5) and 4 contacts in the bottom row (positions 6-9). The exact signal assignment depends on the application (RS-232, RS-485, etc.) and is defined by the system designer.

Is 1731091172 RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest EU restriction of hazardous substances directive.
