This is a signal-only backplane connector — the 0.075A per-contact rating tells you it's sized for differential pairs and low-current logic lines, not power delivery. The contact layout is 40 signal positions with 20 dedicated ground contacts integrated into the same body, giving each signal column a ground reference for controlled-impedance routing. Termination is press-fit through-hole, which means this header presses into plated backplane holes without solder — the compliant pin cold-welds to the barrel. That's the standard for high-reliability backplanes where rework, field replacement, or lead-free assembly constraints rule out wave solder. The press-fit termination requires a specific hole size and PCB thickness — the compliant pin is designed for a controlled interference fit. No solder paste, no wave, no reflow. This connector feeds into a backplane assembly line where the header is pressed into the board with a pneumatic or hydraulic press. The 6-row, 10-column layout means the insertion force adds up; the board needs adequate support under the press area to avoid flexing. ## Contact Plating and Signal Integrity The 20 ground contacts are distributed across the layout to provide a low-inductance return path, which matters when the signal edges are fast enough that the ground plane in the PCB alone isn't enough. This header mates with the Impact series right-angle receptacle; the mated pair defines the stack height and the differential impedance.","metaTitle":"TE Impact 2057427-3 Header, 60 Pos, 1.91mm Pitch, Press-Fit","metaDescription":"TE Connectivity Impact 2057427-3 backplane header, 60 positions (40 signal + 20 ground), 1.91mm pitch, 6 rows, press-fit termination, gold 30µin plating, UL94","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":"10","Base Product Number":"2057427","Number of Positions":"60","Current Rating (Amps)":"0.075A","Operating Temperature":"-55°C ~ 85°C","Contact Layout, Typical":"40 Signal, 20 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":"$9.8700","priceTiers":[{"qty":1,"price":"$9.87000","currency":"USD"},{"qty":10,"price":"$8.93000","currency":"USD"},{"qty":25,"price":"$8.69320","currency":"USD"},{"qty":50,"price":"$8.36260","currency":"USD"},{"qty":100,"price":"$7.74840","currency":"USD"},{"qty":250,"price":"$7.70116","currency":"USD"},{"qty":500,"price":"$7.41768","currency":"USD"},{"qty":1000,"price":"$6.61449","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/99dcf9bbd29d9fd9fb3da90446398b64.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/2057427-3/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for the 2057427-3?","answer":"The 2057427-3 is a vertical header that mates with the Impact series right-angle receptacle.
