The 3.30mm pitch and 5.20mm row spacing set the board footprint — wider than the common 2.54mm pitch, which gives more room for trace routing between pins and supports higher current per contact. The 3.30mm mating pitch is the centre-to-centre distance between adjacent pins in a row. For a 4-position, 2-row layout, the footprint spans 3.30mm × (4/2 - 1) = 3.30mm between the two pins in each row, with 5.20mm between rows. The through-hole termination uses kinked pins with a 3.00mm post length — the kink provides retention during soldering before the solder solidifies. ## Mating half and latch system This header mates with a Grace Inertia GIC series cable receptacle (not included).","metaTitle":"4-1971906-2 TE Connectivity Header, 4 Pos, 3.3mm Pitch","metaDescription":"TE Connectivity 4-1971906-2 Grace Inertia header, 4 circuits, 3.30mm pitch, 2 rows, shrouded, latch holder, UL94 V-0, 250VAC, active production.","metaKeywords":null},"attributes":{"series":"Grace Inertia, GIC","packageCase":null,"mountingType":null,"rohsStatus":"RoHS 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":"Tray","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","Applications":"General Purpose, Industrial","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"2","Pitch - Mating":"0.130\\\" (3.30mm)","Product Status":"Active","Voltage Rating":"250VAC","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Yellow","Insulation Height":"0.561\\\" (14.25mm)","Ingress Protection":"-","Base Product Number":"1971906","Insulation Material":"Polyamide (PA66), Nylon 6/6, Glass Filled","Number of Positions":"4","Row Spacing - Mating":"0.205\\\" (5.20mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.118\\\" (3.00mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-30°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.575\\\" (14.60mm)","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":"$0.3100","priceTiers":[{"qty":1,"price":"$0.31000","currency":"USD"},{"qty":10,"price":"$0.26400","currency":"USD"},{"qty":25,"price":"$0.26320","currency":"USD"},{"qty":80,"price":"$0.25975","currency":"USD"},{"qty":230,"price":"$0.24009","currency":"USD"},{"qty":440,"price":"$0.19732","currency":"USD"},{"qty":945,"price":"$0.18636","currency":"USD"},{"qty":2400,"price":"$0.17321","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b5666a3c6b3bf638e118c34d69032d93.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/4-1971906-2/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 4-1971906-2?","answer":"The mating half is a Grace Inertia GIC series cable receptacle (order code not listed here).
