The 0.250\" (6.35 mm) pitch sets the board footprint and the per-contact current ceiling; at this pitch, the tin-plated phosphor bronze contacts carry the rated load without exceeding the housing's thermal limits. ## What the locking ramp and tin plating mean for the fit The locking ramp provides a positive audible latch when mated with the corresponding Universal MATE-N-LOK plug housing — this is the primary retention mechanism in a vibration-prone environment like an appliance or industrial control panel. Tin-on-tin contact finish is rated for moderate mating cycles (typically 25–50 cycles in this series) and suits applications where the connector is mated during assembly and rarely disconnected in the field. The board guide helps align the header during wave-solder insertion, reducing the chance of bent pins on the through-hole tails. ## Temperature range and housing material The nylon (polyamide) housing carries a UL94 V-2 flammability rating — acceptable for equipment inside an enclosure where a V-0 rating is not mandated.","metaTitle":"643415-1 TE Connectivity Universal MATE-N-LOK Header, 4 Pos","metaDescription":"643415-1 TE Connectivity AMP Connectors Universal MATE-N-LOK header, 4 positions, 0.250\" (6.35 mm) pitch, through-hole, locking ramp, tin contacts, active","metaKeywords":null},"attributes":{"series":"Universal MATE-N-LOK","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Female Socket Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"Universal MATE-N-LOK","Package":"Bulk","Features":"Board Guide","Termination":"Solder","Applications":"-","Contact Type":"Female Socket","Contact Shape":"Circular","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"1","Pitch - Mating":"0.250\\\" (6.35mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Natural","Insulation Height":"0.580\\\" (14.73mm)","Ingress Protection":"-","Base Product Number":"643415","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"4","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.155\\\" (3.94mm)","Current Rating (Amps)":"-","Operating Temperature":"-40°C ~ 105°C","Mated Stacking Heights":"-","Contact Finish - Mating":"Tin","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-2","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0600","priceTiers":[{"qty":1,"price":"$1.06000","currency":"USD"},{"qty":10,"price":"$1.01000","currency":"USD"},{"qty":100,"price":"$0.83210","currency":"USD"},{"qty":500,"price":"$0.75642","currency":"USD"},{"qty":1000,"price":"$0.65408","currency":"USD"},{"qty":5000,"price":"$0.56064","currency":"USD"},{"qty":10000,"price":"$0.55069","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/64c12ef4e9c9974063afead3df8055b9.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/643415-1/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the 643415-1 header?","answer":"The mating pitch is 0.250\" (6.35 mm) — a standard spacing for the Universal MATE-N-LOK series that matches the corresponding plug housing and crimp terminals."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/643415-1","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/643415-1 when reusing this data.
