If your application needs more positions or a different locking style, the 1-1871673-2 is a direct mate alternative — though the dual-row format changes the board footprint.","metaTitle":"1744446-4 TE Economy Power 2.5 Header, 4 Pos, 2.5mm, RA","metaDescription":"1744446-4 TE Connectivity AMP Connectors Economy Power 2.5 header. 4 circuits, 2.5mm pitch, right-angle, shrouded, board lock, glow wire compliant.","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, Glow Wire Compliant","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":"Natural","Insulation Height":"0.299\\\" (7.60mm)","Ingress Protection":"-","Base Product Number":"1744446","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":"-","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":"$0.4300","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.43000","currency":"USD"},{"qty":10,"price":"$0.38800","currency":"USD"},{"qty":100,"price":"$0.32320","currency":"USD"},{"qty":500,"price":"$0.27474","currency":"USD"},{"qty":1000,"price":"$0.24080","currency":"USD"},{"qty":5000,"price":"$0.21494","currency":"USD"},{"qty":10000,"price":"$0.19878","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/67b5df6c315566790c5bb111a0f618aa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What connector mates with 1744446-4?","answer":"This header mates with a matching Economy Power 2.5 receptacle housing (sold separately) that accepts the series' crimp terminals.
