Its 0.049\" (1.25 mm) pitch and right-angle SMT orientation make it a compact choice for routing low-current signals in tight enclosures. The shrouded 4-wall housing protects the male pins during mating and unmating, reducing the risk of bent contacts in field-service applications. ## Current, voltage, and temperature limits Rated at 1 A per contact and 100 VAC, this header is suited for low-power signal or sensor connections rather than power distribution. Tin plating is adequate for moderate mating cycles (typically 25–50) in dry environments; for higher cycle life, consider a gold-plated alternative in the same series. The 1734261-3's tighter 1.25 mm pitch saves board space but limits current to 1 A per contact. The 1-2232960-3 uses a locking ramp for vibration resistance and is through-hole mounted, while the 1734261-3 is SMT right-angle with solder retention.","metaTitle":"1734261-3 TE Connectivity Header SMD R/A 3POS 1.25mm","metaDescription":"1734261-3 TE Connectivity AMP Connectors High Performance Interconnect (HPI) header, 3 positions, 1.25mm pitch, SMD right-angle, shrouded 4-wall, 1A, 100VAC.","metaKeywords":null},"attributes":{"series":"High Performance Interconnect (HPI)","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":"High Performance Interconnect (HPI)","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"Automotive, General Purpose, Industrial, Medical","Contact Type":"Male Pin","Contact Shape":"Rectangular","Mounting Type":"Surface Mount, Right Angle","Connector Type":"Header","Fastening Type":"-","Number of Rows":"1","Pitch - Mating":"0.049\\\" (1.25mm)","Product Status":"Active","Voltage Rating":"100VAC","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Natural","Insulation Height":"0.136\\\" (3.46mm)","Ingress Protection":"-","Base Product Number":"1734261","Insulation Material":"Thermoplastic","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"1A","Operating Temperature":"-25°C ~ 85°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":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1084","priceTiers":[{"qty":1,"price":"$2.06000","currency":"USD"},{"qty":1,"price":"$1.70000","currency":"USD"},{"qty":10,"price":"$1.79600","currency":"USD"},{"qty":10,"price":"$1.55200","currency":"USD"},{"qty":100,"price":"$1.38360","currency":"USD"},{"qty":100,"price":"$1.60530","currency":"USD"},{"qty":500,"price":"$1.33776","currency":"USD"},{"qty":500,"price":"$1.23838","currency":"USD"},{"qty":1000,"price":"$1.10842","currency":"USD"},{"qty":3000,"price":"$1.02433","currency":"USD"},{"qty":5000,"price":"$0.99376","currency":"USD"},{"qty":10000,"price":"$0.94608","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/79997c79c5a773b2d4922d2f36546464.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1734261-3/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 1734261-3 and how do I get a price?","answer":"Submit an RFQ through this page for current pricing and lead time — no stock-holding claim is made here."},{"question":"Is 1734261-3 RoHS compliant?","answer":"Yes, the 1734261-3 is ROHS3 compliant."},{"question":"What connector mates with 1734261-3?","answer":"This header mates with a matching 1.25 mm pitch crimp receptacle housing from the HPI series.
