In a 2-position header, that's 4.2A total through the pair — enough for a small power supply feed, a lighting driver output, or a sensor signal line. The tin-plated mating surface is suitable for moderate mating cycles — expect 25-50 cycles before contact resistance rises. ## Friction Lock and Glow Wire: Two Features That Matter The friction lock provides a positive hold against vibration and accidental disconnection — it's a simple ramp that clicks into the mating receptacle's detent. No separate latch to break. Glow wire compliance means the polyamide housing meets the 750°C glow wire test per IEC 60335-1, a common requirement for household appliances and lighting fixtures. The UL94 V-0 rating confirms the housing self-extinguishes within 10 seconds of flame removal.","metaTitle":"1744446-2 TE Connectivity Header, 2 Pos, 2.5mm, Right Angle","metaDescription":"1744446-2 TE Connectivity AMP Connectors Economy Power 2.5 header, 2 positions, 0.098\" pitch, 4.2A, 250VAC, glow wire compliant, friction lock, active","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":"2","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":"$0.2900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.29000","currency":"USD"},{"qty":10,"price":"$0.24900","currency":"USD"},{"qty":100,"price":"$0.22650","currency":"USD"},{"qty":500,"price":"$0.17584","currency":"USD"},{"qty":1000,"price":"$0.16343","currency":"USD"},{"qty":5000,"price":"$0.14481","currency":"USD"},{"qty":10000,"price":"$0.12826","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the mating connector for 1744446-2?","answer":"The 1744446-2 mates with a 2-position Economy Power 2.5 receptacle housing that has a friction lock feature.
