The board guide aligns the header during insertion, preventing the contacts from stubbing against the housing wall.","metaTitle":"643428-3 TE Connectivity Universal MATE-N-LOK Header 12 Pos","metaDescription":"643428-3 TE Connectivity AMP Connectors Universal MATE-N-LOK header, 12 positions, 0.250\" pitch, through hole, gold contacts.","metaKeywords":null},"attributes":{"series":"Universal MATE-N-LOK","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","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":"3","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":"643428","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"12","Row Spacing - Mating":"0.250\\\" (6.35mm)","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":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9400","priceTiers":[{"qty":1,"price":"$3.94000","currency":"USD"},{"qty":10,"price":"$3.58200","currency":"USD"},{"qty":100,"price":"$3.15580","currency":"USD"},{"qty":500,"price":"$2.68246","currency":"USD"},{"qty":1000,"price":"$2.28799","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/44eada7be2aab86b27d6d7f1904f1ed6.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/643428-3/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of the 643428-3, and is it through hole or SMT?","answer":"The mating pitch is 0.250\" (6.35 mm) between contacts and between rows.
