The shroud has one wall and a friction lock, so the mating receptacle clicks in and stays put under light cable strain. ## What the 7.5A rating means on the bench The 7.5A per contact rating at 250VAC is the maximum continuous current before the temperature rise hits the PA66 housing limit. Derate above 25°C ambient — the operating range goes down to -25°C and up to 105°C, but at the top end the current capacity drops. Tin-on-tin contacts are good for moderate mating cycles; if you need frequent reconnects, the gold-plated sibling in the same series holds up longer.","metaTitle":"1744037-4 TE Connectivity Economy Power Header, 4 Pos","metaDescription":"1744037-4 TE Connectivity AMP Connectors Economy Power series header, 4 positions, 5.08mm pitch, 7.5A, 250VAC, tin contacts, friction lock, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Economy Power","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Style":"Board to Cable/Wire","title":"1744037-4","Series":"Economy Power","Package":"Bulk","Shrouding":"Shrouded - 1 Wall","Termination":"Solder","description":"CONN HEADER VERT 4POS 5.08MM","Applications":"General Purpose, Industrial, 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":"0.200\\\" (5.08mm)","Voltage Rating":"250VAC","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.126\\\" (3.20mm)","Base Product Number":"1744037","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"4","Contact Finish - Post":"Tin","Contact Length - Post":"0.146\\\" (3.70mm)","Current Rating (Amps)":"7.5A","Operating Temperature":"-25°C ~ 105°C","Overall Contact Length":"0.575\\\" (14.60mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.303\\\" (7.70mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"120.0µin (3.05µm)","Contact Finish Thickness - Mating":"120.0µin (3.05µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4300","priceTiers":[{"qty":1,"price":"$0.43000","currency":"USD"},{"qty":10,"price":"$0.39400","currency":"USD"},{"qty":100,"price":"$0.32810","currency":"USD"},{"qty":500,"price":"$0.27890","currency":"USD"},{"qty":1000,"price":"$0.24446","currency":"USD"},{"qty":5000,"price":"$0.21821","currency":"USD"},{"qty":10000,"price":"$0.20305","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1744037-4/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 1744037-4?","answer":"The mating half is a TE Economy Power receptacle housing that accepts the corresponding crimp terminals.
