The shroud is 0.550\" (13.97 mm) tall from the board surface; the solder tails extend 0.155\" (3.94 mm) below the board, so the total z-height above the board plus the tail length determines clearance under the board. ## Current and voltage ceiling for the circuit The operating range is -40°C to 105°C; above 105°C the nylon insulator and tin plating begin to degrade, so derate current if the ambient inside the enclosure exceeds that. ## Locking ramp and vibration resistance","metaTitle":"641966-1 TE Universal MATE-N-LOK Header 3 Pos 6.35mm","metaDescription":"641966-1 TE Connectivity AMP Connectors Universal MATE-N-LOK header, 3 positions, 6.35 mm pitch, 12 A, 600 VAC, tin-plated, through-hole, active production.","metaKeywords":null},"attributes":{"series":"Universal MATE-N-LOK","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Style":"Board to Cable/Wire","title":"641966-1","Series":"Universal MATE-N-LOK","Package":"Bulk","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN HEADER VERT 3POS 6.35MM","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"1","Pitch - Mating":"0.250\\\" (6.35mm)","Voltage Rating":"600VAC","Contact Material":"Phosphor Bronze","Insulation Color":"White","Insulation Height":"0.550\\\" (13.97mm)","Base Product Number":"641966","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"3","Contact Finish - Post":"Tin","Contact Length - Post":"0.155\\\" (3.94mm)","Current Rating (Amps)":"12A","Operating Temperature":"-40°C ~ 105°C","Contact Finish - Mating":"Tin","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2600","priceTiers":[{"qty":1,"price":"$1.26000","currency":"USD"},{"qty":10,"price":"$1.17900","currency":"USD"},{"qty":100,"price":"$1.01470","currency":"USD"},{"qty":500,"price":"$0.89402","currency":"USD"},{"qty":1000,"price":"$0.80078","currency":"USD"},{"qty":5000,"price":"$0.72399","currency":"USD"},{"qty":10000,"price":"$0.67881","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a277e2c2a65e3e21a3c215419ec710c3.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/641966-1/alternatives.json"},"ai":{"faq":[{"question":"What is the 641966-1's connector style?","answer":"The listed style is Board to Cable/Wire — it is a through-hole header intended for wire-to-board power interconnects in harness assemblies."},{"question":"What series does the 641966-1 belong to?","answer":"Universal MATE-N-LOK, the 6.35 mm pitch family TE Connectivity uses across appliance, industrial, and HVAC applications where a locking, vibration-resistant power connector is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/641966-1","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/641966-1 when reusing this data.
