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.","metaTitle":"Molex 1731090359 FCT D-Sub Receptacle, 9-Position, 5A","metaDescription":"Molex 1731090359 FCT D-Sub receptacle, 9 positions, DE-size shell, 5 A per contact, -55°C to 125°C, through-hole solder, UL94 V-0.","metaKeywords":null},"attributes":{"series":"F, FCT 173109","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Cable Assemblies"],"specifications":{"Mfr":"Molex","Color":"White","Series":"F, FCT 173109","Package":"Bulk","Features":"-","Wire Gauge":"-","Termination":"Solder","Contact Form":"Machined","Contact Type":"Signal","Mounting Type":"Through Hole","Connector Type":"Receptacle, Female Sockets","Contact Finish":"-","Flange Feature":"Housing/Shell (Unthreaded)","Number of Rows":"2","Product Status":"Active","Voltage Rating":"-","Backset Spacing":"-","Connector Style":"D-Sub","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Primary Material":"Metal","Ingress Protection":"-","Base Product Number":"173109","Dielectric Material":"Polyester, Glass Filled","Number of Positions":"9","Current Rating (Amps)":"5A","Operating Temperature":"-55°C ~ 125°C","Shell Material, Finish":"Steel, Tin Plated","Contact Finish Thickness":"-","Material Flammability Rating":"UL94 V-0","Shell Size, Connector Layout":"1 (DE, E)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.5500","priceTiers":[{"qty":1,"price":"$9.55000","currency":"USD"},{"qty":10,"price":"$8.30700","currency":"USD"},{"qty":100,"price":"$6.85310","currency":"USD"},{"qty":1000,"price":"$5.69019","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a1f0210aba551f3dbfffe479a679e823.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1731090359/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 1731090359?","answer":"The 1731090359 is available through independent distribution channels."},{"question":"What is the pin configuration of molex 1731090359?","answer":"The 1731090359 has 9 positions arranged in 2 rows, with a DE (E) shell size — the standard DB9 pinout.
