The 3 positions match a 3-wire harness — think sensor power, signal return, or a simple discrete I/O run. Both the mating contact surface and the solder post are tin-plated. In a panel or enclosure subject to machine vibration, that latch keeps the connection from walking loose. ## How It Compares to Nearby Siblings Against the 1-292164-1 (CT series, 2.00 mm pitch, 11 positions, right-angle), the 3-1971798-3 trades a narrower pitch and higher position count for a wider 2.50 mm pitch and a lower 3-position count — a simpler, more robust footprint for a low-circuit harness. The insulation material is thermoplastic; the contact base is copper alloy. ROHS3 Compliant per current TE certification.","metaTitle":"3-1971798-3 TE Connectivity Grace Inertia Header, 3 Pos","metaDescription":"TE Connectivity AMP Connectors 3-1971798-3 Grace Inertia header, 3 circuits, 2.50 mm pitch, shrouded, 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":"Red","Insulation Height":"0.346\\\" (8.80mm)","Ingress Protection":"-","Base Product Number":"1971798","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":"$0.3200","priceTiers":[{"qty":1,"price":"$0.32000","currency":"USD"},{"qty":10,"price":"$0.27200","currency":"USD"},{"qty":100,"price":"$0.21190","currency":"USD"},{"qty":500,"price":"$0.18160","currency":"USD"},{"qty":1000,"price":"$0.15133","currency":"USD"},{"qty":5000,"price":"$0.12971","currency":"USD"},{"qty":10000,"price":"$0.12107","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/700f61f9ef9f5943588cc1fd74036294.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/3-1971798-3/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3-1971798-3 and how is it quoted?","answer":"We source this active-production TE header through independent distribution channels."},{"question":"Is 3-1971798-3 compatible with 2.50 mm pitch connectors?","answer":"Yes — the mating pitch is 2.50 mm (0.098 inch).
