It fits shell size B, which covers both 25-position standard D-subs and 44-position high-density D-subs. The housing is molded from ABS plastic with a nickel-over-copper plating that provides the EMI/RFI shielding — the shield continuity runs from the cable braid through the backshell to the D-sub shell. Included 4-40 mating screws secure the backshell to the D-sub connector, and the assembly hardware and grommets are supplied in the package. ## Position Count and Shell Size — Matching the BOM Line The 5748677-3 is the 25-position member of the AMPLIMITE HD-20 backshell family, using shell size B. The same series offers a 15-position variant (5748677-2) and a 37-position variant (5748677-4) for shell sizes A and C respectively. The 50-position variant (5748677-5) uses shell size D. ## Shielding and Hardware — What Ships in the Bag Shielded construction is standard on the 5748677-3 — the nickel-over-copper plating on the ABS shell provides the conductive path. The backshell ships with the assembly hardware (4-40 screws) and grommets for cable strain relief. No separate hardware kit is needed; it is ready to install on a 25-position D-sub connector with a round cable.","metaTitle":"TE Connectivity 5748677-3 AMPLIMITE HD-20 Backshell, 25-Pos","metaDescription":"TE Connectivity 5748677-3 AMPLIMITE HD-20 two-piece backshell, 25 positions, shielded, 180° cable exit, nickel over copper plating, 4-40 mating screws.","metaKeywords":null},"attributes":{"series":"AMPLIMITE HD-20","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":"Silver","Series":"AMPLIMITE HD-20","Package":"Bulk","Plating":"Nickel over Copper","Features":"Mating Screws 4-40","Hardware":"Assembly Hardware, Grommets","Material":"Acrylonitrile Butadiene Styrene (ABS)","Shielding":"Shielded","Cable Exit":"180°","Cable Type":"Round","Accessory Type":"Two Piece Backshell","Product Status":"Active","lifecycle_stage":"unknown","Primary Material":"Plastic","Base Product Number":"5748677","Number of Positions":"25","Compatible D-Sub Size":"25pos and HD44pos","Compatible Shell Size":"B"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.7800","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.78000","currency":"USD"},{"qty":10,"price":"$9.75200","currency":"USD"},{"qty":25,"price":"$9.49400","currency":"USD"},{"qty":50,"price":"$9.13300","currency":"USD"},{"qty":100,"price":"$8.46210","currency":"USD"},{"qty":250,"price":"$8.41052","currency":"USD"},{"qty":500,"price":"$8.10094","currency":"USD"},{"qty":1000,"price":"$7.22377","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/29ea6f229820c5acf57b17054187e8d6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 5748677-3 backshell and how do I get a price?","answer":"No stock-holding or firm price is published here."},{"question":"Is the 5748677-3 shielded and does it include mounting hardware?","answer":"Yes, the 5748677-3 is a shielded backshell with nickel-over-copper plating on the ABS housing.
