Rated 250 VAC / 350 VDC — the voltage ceiling is sufficient for signal-level and low-power circuits in general-purpose equipment. ## Tin-Plated Contacts, Board-to-Cable Duty Tin is suitable for indoor, non-corrosive environments; for repeated field-service mating, a gold-plated sibling in the EI series would extend cycle life. The contact material is brass, formed as a square male pin. Available in Bulk packaging. ## Mating Half and Series Position This header mates with a TE Connectivity EI series receptacle housing (wire-to-board) that accepts the corresponding crimp terminals. The EI series is a general-purpose, low-cost header family from TE, positioned below the Micro-Fit and Mini-Fit families in current and cycle life. For higher current or more mating cycles, consider the Micro-Fit 3.0 series (5 A per contact, gold plating option).","metaTitle":"172732-4 TE Connectivity EI Header, 4 Pos, 2.5 mm Pitch","metaDescription":"172732-4 TE Connectivity AMP Connectors EI series header, 4 circuits, 2.50 mm pitch, single row, shrouded, latch holder, through hole, tin contacts, ROHS3","metaKeywords":null},"attributes":{"series":"EI","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":"EI","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 1 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":"250VAC, 350VDC","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Natural","Insulation Height":"0.409\\\" (10.40mm)","Ingress Protection":"-","Base Product Number":"172732","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"4","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.142\\\" (3.60mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-20°C~95°C","Mated Stacking Heights":"-","Overall Contact Length":"0.551\\\" (14.00mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.295\\\" (7.49mm)","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":"$0.8100","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.81000","currency":"USD"},{"qty":10,"price":"$0.70300","currency":"USD"},{"qty":100,"price":"$0.57980","currency":"USD"},{"qty":500,"price":"$0.50420","currency":"USD"},{"qty":1000,"price":"$0.41596","currency":"USD"},{"qty":5000,"price":"$0.36554","currency":"USD"},{"qty":10000,"price":"$0.34033","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/72462b32556a6c2949cae1bf6a2a63df.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 172732-4 RoHS compliant?","answer":"Yes, it is ROHS3 compliant."},{"question":"What is the mating connector for 172732-4?","answer":"The mating half is a TE Connectivity EI series receptacle housing for 4 circuits, 2.50 mm pitch, with a latch feature.
