Termination is through-hole with kinked pins — the kink provides retention during soldering and prevents the header from falling out during wave solder. A board guide feature aids alignment during assembly, reducing the risk of pin damage when mating the harness. The insulation height of 0.346\" (8.80 mm) gives clearance for the latch mechanism and the mating receptacle housing.","metaTitle":"3-1971800-4 TE Connectivity 2.5mm 3-Pin Header, Shrouded","metaDescription":"3-1971800-4 TE Connectivity AMP Connectors Grace Inertia header, 3 positions, 2.50mm pitch, shrouded 4-wall, latch holder, tin contacts, UL94 V-0.","metaKeywords":null},"attributes":{"series":"Grace Inertia, GIC","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":"Grace Inertia, GIC","Package":"Bulk","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"1","Pitch - Mating":"0.098\\\" (2.50mm)","Product Status":"Active","Voltage Rating":"50V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Yellow","Insulation Height":"0.346\\\" (8.80mm)","Ingress Protection":"-","Base Product Number":"1971800","Insulation Material":"Thermoplastic","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-30°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":"$0.2400","priceTiers":[{"qty":1,"price":"$0.24000","currency":"USD"},{"qty":10,"price":"$0.20400","currency":"USD"},{"qty":100,"price":"$0.18500","currency":"USD"},{"qty":500,"price":"$0.14360","currency":"USD"},{"qty":1000,"price":"$0.13346","currency":"USD"},{"qty":5000,"price":"$0.11825","currency":"USD"},{"qty":10000,"price":"$0.10474","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-1971800-4/alternatives.json"},"ai":{"faq":[{"question":"What connects to 3-1971800-4?","answer":"This header mates with a Grace Inertia series receptacle housing that accepts the corresponding crimp terminals.
