It accepts standard 25-position D-sub shells and also fits high-density 44-position shells that share the same B shell size. The polyamide (nylon) body is black, and the package is bulk. The backshell includes the 4-40 mating screws and a cable clamp as part of the assembly hardware, so you don't need to source those separately. ## What's Included — Hardware and Fit The 4-40 mating screws are included with the backshell, answering the common question of whether you need to order them separately. The assembly hardware also includes a cable clamp for strain relief on round cable. The hinged design allows the backshell to open for cable termination and then close over the connector, securing the cable exit at 180°. The backshell is unshielded, so it's suited for applications where EMI/RFI shielding is handled elsewhere in the cable assembly or where the environment doesn't require a shielded backshell.","metaTitle":"TE Connectivity 2-1991253-5 D-Sub Backshell, 25-Pos","metaDescription":"TE Connectivity 2-1991253-5 hinged backshell for 25-position D-sub connectors. 180° cable exit, includes 4-40 mating screws and cable clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["D-Sub & D-Shaped Connectors","D-Sub Backshells & Hoods"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Series":"-","Package":"Bulk","Plating":"-","Features":"Mating Screws 4-40","Hardware":"Assembly Hardware, Cable Clamp","Material":"Polyamide (PA), Nylon","Shielding":"Unshielded","Cable Exit":"180°","Cable Type":"Round","Accessory Type":"Hinged Backshell","Product Status":"Active","lifecycle_stage":"unknown","Primary Material":"Plastic","Base Product Number":"1991253","Number of Positions":"25","Compatible D-Sub Size":"25pos and HD44pos","Compatible Shell Size":"B"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.47000","currency":"USD"},{"qty":10,"price":"$2.20200","currency":"USD"},{"qty":25,"price":"$2.19040","currency":"USD"},{"qty":50,"price":"$2.16820","currency":"USD"},{"qty":100,"price":"$1.98930","currency":"USD"},{"qty":250,"price":"$1.97812","currency":"USD"},{"qty":500,"price":"$1.79932","currency":"USD"},{"qty":1000,"price":"$1.60932","currency":"USD"},{"qty":2500,"price":"$1.48639","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Does the 2-1991253-5 come with Mating Screws 4-40 included?","answer":"Yes, the 4-40 mating screws are included as part of the assembly hardware, along with a cable clamp."},{"question":"What is the cross reference or equivalent for 2-1991253-5?","answer":"The backshell fits any standard 25-position D-sub with a B shell size, and also fits high-density 44-position D-subs using the same shell size."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/2-1991253-5","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/te-connectivity-amp-connectors/2-1991253-5 when reusing this data.
