This is the dense, high-speed backplane connector from the Impact series, with a contact layout of 64 signal and 32 ground paths — a 2:1 signal-to-ground ratio that gives each differential pair a dedicated return path without crowding the routing channels. The press-fit termination means the header is pressed into plated through-holes on the backplane, no solder required, which keeps the assembly rework-friendly and the contact interface gas-tight. ## What the 0.075 A rating actually means for this connector The 0.075A per-contact current rating looks low, but this is a signal connector, not a power interconnect. Each signal pin carries logic-level current — think differential pair lanes at a few milliamps. The 30V rating matches the signal voltage domain on a typical backplane. ## Press-fit backplane assembly — no solder, no reflow The press-fit termination eliminates the solder joint as a failure point. The compliant pin compresses as it enters the plated through-hole, cold-welding to the barrel wall. The base product number is 2057747, and the full 12NC suffix defines the 96-position, press-fit, gold-plated variant. There is no official TE cross-reference or replacement — this is the active part number for the specification. ## Mating half and build-to-print checklist This header mates with the Impact-series right-angle receptacle (the female counterpart) that mounts on the daughter card. The 1.91mm pitch and 6-row grid are mirrored on the receptacle side. For a complete build-to-print BOM, you need the mating receptacle, the press-fit insertion tooling, and the backplane PCB with the correct plated through-hole pattern. The header ships in bulk packaging — no tape-and-reel, no carrier.","metaTitle":"TE Impact 2057747-3 Backplane Header, 96 Pos, 1.91mm Pitch","metaDescription":"TE Impact 2057747-3 header, 96 positions (64 signal + 32 ground), 6 rows, 1.91mm pitch, press-fit termination, gold 30µin, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Impact","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Circular Connectors","Specialty Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Pitch":"0.075\\\" (1.91mm)","Series":"Impact","Package":"Bulk","Features":"-","Termination":"Press-Fit","Mounting Type":"Through Hole","Connector Type":"Header, Male Pins","Contact Finish":"Gold","Number of Rows":"6","Product Status":"Active","Voltage Rating":"30V","Connector Style":"Impact","Connector Usage":"-","lifecycle_stage":"unknown","Number of Columns":"16","Base Product Number":"2057747","Number of Positions":"96","Current Rating (Amps)":"0.075A","Operating Temperature":"-55°C ~ 85°C","Contact Layout, Typical":"64 Signal, 32 Ground","Contact Finish Thickness":"30.0µin (0.76µm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.8500","priceTiers":[{"qty":1,"price":"$13.85000","currency":"USD"},{"qty":10,"price":"$13.56600","currency":"USD"},{"qty":25,"price":"$13.20480","currency":"USD"},{"qty":50,"price":"$12.55540","currency":"USD"},{"qty":100,"price":"$11.32880","currency":"USD"},{"qty":250,"price":"$11.25664","currency":"USD"},{"qty":500,"price":"$9.81350","currency":"USD"},{"qty":1000,"price":"$9.74133","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/99621239808c4bc5681a6e863b968b16.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/2057747-3/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the 2057747-3 and how do I get a price?","answer":"The 2057747-3 is sourced to order through independent distribution."},{"question":"What backplane connector does the 2057747-3 mate with?","answer":"The 2057747-3 mates with the Impact-series right-angle receptacle.
