Standard DB9 Female Receptacle with Machined Contacts
The Molex 1731090359 is a 9-position D-Sub receptacle from the FCT 173109 series — a standard DE-size (DB9) female connector built for reliable signal interconnect in industrial, instrumentation, and data-communication equipment. The 2-row layout with a steel, tin-plated shell mates with any standard DB9 male plug, making it a drop-in replacement or BOM match for legacy and new designs.
Temperature Range and Current Duty
The wide temperature window means the connector can be specified for equipment cycling between cold storage and hot enclosures — think industrial control cabinets or outdoor telecom gear — without derating at the extremes.
Through-hole solder termination with an unthreaded housing/shell flange — this receptacle mounts flush to a panel or bracket using the standard D-sub cutout for DE-size connectors.
What Crosses When the Standard Line is Dry?
The 1731090359 is a standard DB9 female receptacle — the shell size, pin count, and layout match the industry-standard DE-9 footprint. Any standard DB9 male plug with the same DE-size shell and 2-row arrangement mates directly. No official cross-reference is on record, but the FCT series is a known second-source for D-subminiature connectors; if the Molex line has lead-time pressure, a standard DB9 receptacle from Amphenol, TE, or NorComp with the same DE shell, 9 positions, and through-hole termination is a functional equivalent. Confirm the flange style (unthreaded housing) and the mounting hole pattern match your panel cutout before committing.
