Compare this to the 12-position, 0.100-inch (2.54mm) pitch 1-2823056-2 receptacle (peer): that part packs four times the circuits into roughly the same board width, but at a lower per-contact current ceiling due to the tighter pitch. It is still in regular production with no announced end-of-life or successor. The base product number 643414 covers the series variants; this specific 3-position, tin-plated version is the most commonly stocked configuration. Sourced through independent distribution channels. The mated pair is keyed to prevent misalignment. Termination is through-hole solder — the header is inserted into the PCB and wave-soldered. The board guide (feature) centers the part during placement. The tin-plated posts (contact finish - post) are solderable with standard rosin-core solder; no special flux is required.","metaTitle":"643414-1 TE Connectivity Universal MATE-N-LOK Header 3 Pos","metaDescription":"643414-1 TE Connectivity AMP Connectors Universal MATE-N-LOK header, 3 positions, 0.250\" (6.35mm) pitch, tin-plated contacts, through-hole solder termination","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":"White","Insulation Height":"0.580\\\" (14.73mm)","Ingress Protection":"-","Base Product Number":"643414","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"3","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-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4100","priceTiers":[{"qty":1,"price":"$1.41000","currency":"USD"},{"qty":10,"price":"$1.22500","currency":"USD"},{"qty":100,"price":"$1.09470","currency":"USD"},{"qty":500,"price":"$0.91226","currency":"USD"},{"qty":1000,"price":"$0.78194","currency":"USD"},{"qty":5000,"price":"$0.69332","currency":"USD"},{"qty":10000,"price":"$0.67768","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5b0782f030fd8b04a023955a781edada.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/643414-1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 643414-1 and how do I get a price?","answer":"The 643414-1 is available through independent distribution.
