Mating contacts are beryllium copper with 25µinch gold over nickel — a production-grade finish that holds up to repeated IC insertions in test sockets, programming fixtures, and field-replaceable modules. The gold layer resists oxidation in environments where the socket sees intermittent power-down cycles. ## Thermal and Compliance Ratings The UL94 V-0 flammability rating means it passes the vertical burn test for equipment inside an enclosure, a common requirement for power supplies and industrial controllers. Contact resistance is specified at 10 mOhm maximum — a tight ceiling that keeps the voltage drop across the socket negligible in low-voltage logic circuits. The solder-tail length is 0.125\" (3.18mm), enough for a good through-hole fillet on a standard 1.6mm PCB.","metaTitle":"5-1571551-2 TE Connectivity DIP Socket 40-Pin 0.6\" Row","metaDescription":"5-1571551-2 TE Connectivity AMP Connectors 500 Series DIP socket, 40 (2x20) positions, 0.100\" pitch, 0.6\" row spacing, 25µin gold mating contacts, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Type":"DIP, 0.6\\\" (15.24mm) Row Spacing","Series":"500","Package":"Tube","Features":"Closed Frame","Termination":"Solder","Pitch - Post":"0.100\\\" (2.54mm)","Mounting Type":"Through Hole","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","lifecycle_stage":"unknown","Housing Material":"Polycyclohexylenedimethylene Terephthalate (PCT), Polyester","Contact Resistance":"10mOhm","Base Product Number":"1571551","Contact Finish - Post":"Gold","Operating Temperature":"-55°C~125°C","Contact Finish - Mating":"Gold","Contact Material - Post":"Nickel","Termination Post Length":"0.125\\\" (3.18mm)","Contact Material - Mating":"Beryllium Copper","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"25.0µin (0.63µm)","Contact Finish Thickness - Mating":"25.0µin (0.63µm)","Number of Positions or Pins (Grid)":"40 (2 x 20)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7b81b619fa3901b7dc4eb4e9b6ac4186.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/5-1571551-2/alternatives.json"},"ai":{"faq":[{"question":"What is the row spacing of 5-1571551-2?","answer":"The row spacing is 0.6\" (15.24mm), which is the standard for 40-pin DIP packages — measure between the two rows of holes on your PCB layout to confirm fit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5-1571551-2","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/5-1571551-2 when reusing this data.
