The 105°C upper limit covers most indoor industrial environments and some outdoor cabinets, though the tin-plated contacts (3.00µm on mating face) limit reconnect cycles compared to gold. ## Mounting and Shrouding Details Surface-mount termination with a shrouded 4-wall design and latch lock. The SMT footprint saves board space versus through-hole, but the latch lock adds a positive tactile click during mating — a hand-tight should seal it, but check that the latch engages fully to avoid a half-turn loose dropout in service. Insulation height is 0.181\" (4.60mm), so plan z-height accordingly. Housing is polyamide 4/6 (PA46) glass-filled, rated UL94 V-0 for flame retardance. ROHS3 compliant per the lifecycle record. ## Peer Alternative — 1-1871673-2 It uses a detent lock instead of a latch, and current is wire-gauge dependent rather than a fixed 1.5A. The 338728-4 is SMT; the 1-1871673-2 is through-hole — choose based on your assembly process and board orientation.","metaTitle":"338728-4 TE Connectivity Micro-MaTch SMT Header, 4 Pos","metaDescription":"338728-4 TE Connectivity AMP Connectors Micro-MaTch SMT header, 4 positions, 2 rows, 0.100\" (2.54mm) pitch, shrouded, latch lock, 1.5A, 230V, -40°C~105°C, UL94","metaKeywords":null},"attributes":{"series":"Micro-MaTch","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 Board or Cable","Series":"Micro-MaTch","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"-","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Rectangular","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Latch Lock","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"230V","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Red","Insulation Height":"0.181\\\" (4.60mm)","Ingress Protection":"-","Base Product Number":"338728","Insulation Material":"Polyamide (PA46), Nylon 4/6, Glass Filled","Number of Positions":"4","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"1.5A","Operating Temperature":"-40°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":"118.1µin (3.00µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7207","priceTiers":[{"qty":1,"price":"$2.00000","currency":"USD"},{"qty":10,"price":"$1.74200","currency":"USD"},{"qty":100,"price":"$1.55640","currency":"USD"},{"qty":500,"price":"$1.29700","currency":"USD"},{"qty":1000,"price":"$1.11172","currency":"USD"},{"qty":6000,"price":"$0.72069","currency":"USD"},{"qty":12000,"price":"$0.70444","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/884e190d4fb11ceca227ebc523615179.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/338728-4/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch and position count of 338728-4?","answer":"The pitch is 0.100\" (2.54mm) with 4 positions in 2 rows.
