This is the defining feature of this part: instead of a standard 9-position D-Sub with all signal contacts, the combo layout reserves four positions for coax or power contacts, letting you route mixed-signal and higher-current or RF lines through a single connector shell. ## 5A per Contact — Signal-Duty Current, Not Bus-Level Power Each signal contact is rated 5A. That is standard for D-Sub signal pins — enough for logic-level power, sensor inputs, or low-current control lines. The coax or power positions in the 9W4 layout are not pre-populated; you select the appropriate coax or power contact (not included) to match the current or frequency your application needs. The 5A rating on the signal contacts means this is not a main-bus power connector — treat the signal positions as signal or low-power duty, and size the coax/power positions separately. ## Right-Angle Through-Hole — Board-Edge Fit The 4-40 threaded insert on the board side accepts standard D-Sub jack-screws for mechanical retention against the mating plug. ## Gold Contacts, Wide Temperature Range, UL94 V-0","metaTitle":"Molex 1731070101 D-Sub Combo Receptacle, 9W4, Right-Angle","metaDescription":"Molex FM, FCT 173107 D-Sub combo receptacle, 9 positions (5 signal + 4 coax/power), right-angle through-hole, gold contacts, UL94 V-0, -55°C to 130°C.","metaKeywords":null},"attributes":{"series":"FM, FCT 173107","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Cable Assemblies"],"specifications":{"Mfr":"Molex","Color":"Green","Series":"FM, FCT 173107","Package":"Bulk","Features":"Mounting Brackets","Wire Gauge":"-","Termination":"Solder","Contact Form":"-","Contact Type":"Signal and Coax or Power (Not Included)","Mounting Type":"Through Hole, Right Angle","Connector Type":"Receptacle, Female Sockets","Contact Finish":"Gold","Flange Feature":"Board Side (4-40)","Number of Rows":"2","Product Status":"Active","Voltage Rating":"-","Backset Spacing":"-","Connector Style":"D-Sub, Combo","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Ingress Protection":"-","Base Product Number":"173107","Dielectric Material":"Polyester, Glass Filled","Number of Positions":"9 (5 + 4 Coax or Power)","Current Rating (Amps)":"5A","Operating Temperature":"-55°C ~ 130°C","Shell Material, Finish":"Steel, Tin Plated","Contact Finish Thickness":"-","Material Flammability Rating":"UL94 V-0","Shell Size, Connector Layout":"3 (DB, B) - 9W4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.4900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$14.49000","currency":"USD"},{"qty":10,"price":"$12.84100","currency":"USD"},{"qty":100,"price":"$10.20710","currency":"USD"},{"qty":1000,"price":"$8.75832","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/fe5e405fcd5c7b7da935312e4c9b6a19.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between 1731070101 and a standard 9-position D-Sub?","answer":"The 1731070101 uses a 9W4 combo layout: 5 signal contacts plus 4 positions for coax or power contacts, rather than 9 signal contacts. The shell size is the same 3 (DB, B) layout as a standard DB-9, but the contact arrangement is different — the four coax/power positions replace four signal positions. This means the mating plug must also be a 9W4 combo type, not a standard 9-position D-Sub plug."},{"question":"Where can I buy 1731070101?","answer":"Submit a request for current pricing and lead time — availability is confirmed at quote time, not on the product page."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/1731070101","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/molex/1731070101 when reusing this data.
