The header loads all 3 positions (no skipped pins). The mating pin length is 0.280\" (7.11 mm), which clears the shroud height of 0.410\" (10.41 mm). ## Current, voltage, and temperature range The part is ROHS3 compliant, with no lead or restricted substances — ready for global shipping.","metaTitle":"3-644893-3 TE Connectivity CST-100 Header 3 Pos 2.54 mm","metaDescription":"3-644893-3 TE Connectivity AMP Connectors CST-100 header, 3 positions, 0.100\" (2.54 mm) pitch, shrouded, friction lock, tin-plated, UL94 V-0, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"CST-100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"CST-100","Package":"Bulk","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose, Lighting","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Friction Lock","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"250VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.410\\\" (10.41mm)","Ingress Protection":"-","Base Product Number":"644893","Insulation Material":"Polyester","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.140\\\" (3.56mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.520\\\" (13.21mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.280\\\" (7.11mm)","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":"$1.0000","priceTiers":[{"qty":1,"price":"$1.00000","currency":"USD"},{"qty":10,"price":"$0.95600","currency":"USD"},{"qty":100,"price":"$0.78760","currency":"USD"},{"qty":500,"price":"$0.71596","currency":"USD"},{"qty":1000,"price":"$0.61909","currency":"USD"},{"qty":5000,"price":"$0.53065","currency":"USD"},{"qty":10000,"price":"$0.52123","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-644893-3/alternatives.json"},"ai":{"faq":[{"question":"Is 3-644893-3 RoHS compliant?","answer":"Yes, it is ROHS3 compliant — no lead, mercury, cadmium, or other restricted substances above the threshold limits."},{"question":"What mates with 3-644893-3?","answer":"The friction lock requires a matching housing with a lock ramp — check the receptacle's fastening type."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/3-644893-3","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/3-644893-3 when reusing this data.
