The 4 A per circuit rating at 48 V suits low-to-moderate power distribution and signal-level interconnects — think interior lighting modules, sensor harnesses, or control unit headers in automotive and industrial gear. The 0.100\" pitch and 0.096\" row spacing define a compact footprint that fits a 2.54mm grid, but the dual-row layout means the board pad pattern must match both dimensions. ## Where it fits — temperature and environment No end-of-life notice is on record, and no official successor has been designated.","metaTitle":"Amphenol Minitek MicroSpace 10143578-102KLF, 2-pos Header","metaDescription":"Amphenol Minitek MicroSpace 1.27mm 2-position dual-row SMT header, 0.100\" pitch, 48V, 4A per circuit, tin-plated contacts, latch holder, UL94 V-0, -40 to 130°C.","metaKeywords":null},"attributes":{"series":"Minitek MicroSpace™ 1.27mm","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Style":"Board to Cable/Wire","title":"10143578-102KLF","Series":"Minitek MicroSpace™ 1.27mm","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Board Guide, Solder Retention","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","description":"CONN MICROSPACE HDR-ASSY STG S","Applications":"Automotive, General Purpose, Industrial","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Voltage Rating":"48V","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.526\\\" (13.35mm)","Base Product Number":"10143578","Insulation Material":"Thermoplastic","Number of Positions":"2","Row Spacing - Mating":"0.096\\\" (2.43mm)","Contact Finish - Post":"Tin","Current Rating (Amps)":"4A","Operating Temperature":"-40°C~130°C","Contact Finish - Mating":"Tin","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"118.1µin (3.00µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4200","priceTiers":[{"qty":1,"price":"$1.42000","currency":"USD"},{"qty":10,"price":"$1.19900","currency":"USD"},{"qty":25,"price":"$1.15000","currency":"USD"},{"qty":50,"price":"$1.12580","currency":"USD"},{"qty":100,"price":"$1.07680","currency":"USD"},{"qty":215,"price":"$1.07679","currency":"USD"},{"qty":430,"price":"$0.97888","currency":"USD"},{"qty":645,"price":"$0.88101","currency":"USD"},{"qty":1075,"price":"$0.78312","currency":"USD"},{"qty":1505,"price":"$0.73417","currency":"USD"},{"qty":5375,"price":"$0.68522","currency":"USD"},{"qty":10750,"price":"$0.65096","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/10143578-102KLF/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 10143578-102KLF?","answer":"Submit your BOM quantity for a same-day quote."},{"question":"What is the current rating per circuit for 10143578-102KLF?","answer":"The current rating is 4 A per circuit at 48 V, suitable for low-to-moderate power distribution and signal interconnects."},{"question":"How does 10143578-102KLF compare to the 8-position 10143578-108KLF?","answer":"The 10143578-108KLF is the same header with 8 positions — identical pitch, row spacing, current rating, plating, latch holder, and SMT footprint.
