It provides a 180° straight cable exit for round cable, with the backshell body in gray polyamide (nylon). Assembly hardware and strain relief are included, so you don't need to source those separately. This is an unshielded backshell; if your application requires EMI/RFI protection, you'll need a shielded variant — this one won't provide that path. ## Compatibility Check: Which D-Sub Shells It Fits The 1731110003 is listed as compatible with D-sub shell size E, which covers both 9-position and HD15-position connectors. That means it will fit a standard DE-9 (DB-9) hood footprint and also the larger HD-15 shell used on VGA and some industrial I/O. The 180° exit keeps the cable running straight out the back — no right-angle bend, so plan your harness routing accordingly. The shell size E is the smaller of the common D-sub shell sizes, so this backshell won't fit a 15-position standard-density or 25-position connector. ## What's in the Bag: Hardware and Strain Relief The listing confirms this backshell ships with assembly hardware and strain relief included. That typically means the jack screws (or slide locks), the screws that clamp the backshell halves together, and a strain-relief clamp that grips the cable jacket. For a harness builder, that saves a separate hardware kit order — you get the full set in one bag. The strain relief is sized for round cable, so if you're using a flat ribbon cable, this won't clamp it properly.","metaTitle":"Molex 1731110003 F-PHG Backshell, 9-Pos, 180° Exit, Gray","metaDescription":"Molex 1731110003 one-piece backshell for standard 9-pin D-sub connectors. 180° cable exit, includes assembly hardware and strain relief.","metaKeywords":null},"attributes":{"series":"F-PHG, FCT 173111","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Backshells & Hoods"],"specifications":{"Mfr":"Molex","Color":"Gray","Series":"F-PHG, FCT 173111","Package":"Bulk","Plating":"-","Features":"-","Hardware":"Assembly Hardware, Strain Relief","Material":"Polyamide (PA), Nylon","Shielding":"Unshielded","Cable Exit":"180°","Cable Type":"Round","Accessory Type":"One Piece Backshell","Product Status":"Active","lifecycle_stage":"unknown","Primary Material":"Plastic","Base Product Number":"173111","Number of Positions":"9","Compatible D-Sub Size":"9pos and HD15pos","Compatible Shell Size":"E"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9900","priceTiers":[{"qty":1,"price":"$2.99000","currency":"USD"},{"qty":10,"price":"$2.62900","currency":"USD"},{"qty":100,"price":"$2.09130","currency":"USD"},{"qty":1000,"price":"$1.73280","currency":"USD"},{"qty":2500,"price":"$1.61329","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/f55accf5a80e775561016f6c72943cdf.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1731110003/alternatives.json"},"ai":{"faq":[{"question":"Is the Molex 1731110003 backshell compatible with standard 9-pin D-sub connectors?","answer":"Yes.
