No stock-holding claim; we source against your BOM quantity. The 1-1871673-2 is a dual-row, 4-position header in the same Economy Power 2.5 series, with a detent lock instead of friction lock, and square pins versus circular. Both share the 2.50mm pitch and tin plating, but the dual-row version adds a second row at 3.30mm spacing and uses a box package.","metaTitle":"1744426-4 TE Connectivity Economy Power 2.5 Header, 4 Pos","metaDescription":"1744426-4 TE Connectivity AMP Connectors Economy Power 2.5 header.","metaKeywords":null},"attributes":{"series":"Economy Power 2.5","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":"Economy Power 2.5","Package":"Bulk","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","Applications":"General Purpose, Industrial, Lighting","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Friction Lock","Number of Rows":"1","Pitch - Mating":"0.098\\\" (2.50mm)","Product Status":"Active","Voltage Rating":"250VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"White","Insulation Height":"0.299\\\" (7.60mm)","Ingress Protection":"-","Base Product Number":"1744426","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"4","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.126\\\" (3.20mm)","Current Rating (Amps)":"4.2A","Operating Temperature":"-55°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.141\\\" (3.60mm)","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":"$0.3900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.39000","currency":"USD"},{"qty":10,"price":"$0.35100","currency":"USD"},{"qty":25,"price":"$0.34920","currency":"USD"},{"qty":50,"price":"$0.34180","currency":"USD"},{"qty":100,"price":"$0.29220","currency":"USD"},{"qty":250,"price":"$0.26292","currency":"USD"},{"qty":500,"price":"$0.24832","currency":"USD"},{"qty":1000,"price":"$0.21765","currency":"USD"},{"qty":2500,"price":"$0.21619","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/da02d3fcd57fc6f84a6aa5a4a86ae011.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating half for 1744426-4?","answer":"This header mates with a corresponding Economy Power 2.5 receptacle housing (sold separately).
