The locking ramp fastening holds the header mated under vibration — the ramp clicks into the mating receptacle and resists back-out from cable tug or machine shake. ## Three positions, tin contacts, and the mounting flange Three positions loaded in a single row — the board footprint is three holes on 0.250\" centers, with the mounting flange adding two mechanical anchors outside the signal row for panel or chassis securement. Solder termination to the PCB — the 0.160\" (4.06mm) post length provides enough through-hole protrusion for a reliable solder fillet on standard 1.6mm boards.","metaTitle":"TE 643228-1 Universal MATE-N-LOK Header 3 Pos 6.35mm R/A Tin","metaDescription":"TE Connectivity 643228-1 Universal MATE-N-LOK header, 3 positions, 0.250\" pitch, through-hole right-angle, tin plating, locking ramp, UL94 V-0.","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":"Mounting Flange","Termination":"Solder","Applications":"-","Contact Type":"Female Socket","Contact Shape":"Circular","Mounting Type":"Through Hole, Right Angle","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":"0.360\\\" (9.14mm)","Ingress Protection":"-","Base Product Number":"643228","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.160\\\" (4.06mm)","Current Rating (Amps)":"-","Operating Temperature":"-","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":"$2.8000","priceTiers":[{"qty":1,"price":"$2.80000","currency":"USD"},{"qty":10,"price":"$2.50000","currency":"USD"},{"qty":100,"price":"$2.25880","currency":"USD"},{"qty":500,"price":"$2.04304","currency":"USD"},{"qty":1000,"price":"$1.82731","currency":"USD"},{"qty":5000,"price":"$1.61158","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6e0bb6d3873bbac3bee72439a4133dcd.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/643228-1/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 643228-1?","answer":"The 643228-1 mates with Universal MATE-N-LOK receptacle housings that accept crimp-socket contacts.
