The Amphenol 10143535-105KLF is a 5-position, 2-row vertical SMT header from the Minitek MicroSpace™ 1.27mm series, designed for board-to-cable/wire interconnect in automotive, general purpose, and industrial applications. The series name references the 1.27mm contact spacing within the row, but the mating pitch between rows is the more critical footprint dimension at 0.100" (2.54mm) — the row-to-row spacing is 0.096" (2.43mm).
The 0.100" (2.54mm) mating pitch is the dimension that defines the board footprint — this is a standard 2.54mm header pitch, not a 1.27mm pitch. The 1.27mm in the series name refers to the contact-to-contact spacing within each row. The 5-position count is loaded fully across both rows, giving a 2 x 5 layout. Against the 6-position 10143535-106KLF or the 4-position 10143535-104KLF in the same series, the footprint length scales with position count at the same 2.54mm pitch — match the circuit count on your BOM directly to the position count.
Current, voltage, and contact finish
Rated 4A per contact at 48V. The 48V rating keeps it in the low-voltage domain; the limiting factor for higher voltage is the creepage distance across the 2.54mm pitch and the thermoplastic housing material.
