The Amphenol 10143535-104KLF is a 4-position, dual-row surface-mount header from the Minitek MicroSpace™ 1.27mm series. Despite the series name, the mating pitch is 0.100" (2.54mm) — the 1.27mm refers to the wire-to-board pitch on the receptacle side. This is a board-to-cable/wire interconnect, meaning it solders to a PCB and mates with a crimp-style receptacle housing.
This connector is rated for Automotive, General Purpose, and Industrial applications.
Rated 4 A per circuit at 48 V. The 4 A is adequate for sensor power, actuator signals, and low-current loads — not a high-current bus bar, but enough for most automotive and industrial I/O. The 48 V rating matches the standard automotive nominal voltage and low-voltage industrial control circuits. The tin-plated mating contacts carry a 118.1µin (3.00µm) thickness — a robust tin finish for moderate mating cycles (50-100) in clean, dry environments. If your application sees frequent mating or corrosive atmospheres, consider the gold-plated variants in this series.
Position Count Options in This Series
This 4-position header (10143535-104KLF) is the lowest circuit count in the dual-row Minitek MicroSpace 1.27mm SMT header family. The same footprint, pitch, and ratings are shared with the 5-position 10143535-105KLF, the 6-position 10143535-106KLF, and the 12-position 10143535-112KLF. All share the 0.100" (2.54mm) mating pitch, 4 A rating, 48 V rating, latch holder, and UL94 V-0 housing.
It is ROHS3 compliant. The part is available in Tape & Reel (TR) and Cut Tape (CT) packaging, making it suitable for both automated SMT lines and prototype builds.
