Molex KK 254 7 Way Vertical Pin Header, 2.54mm Pitch, Tin Plated

The Molex KK 254 7 Way Vertical Pin Header is a robust and versatile single-row connector designed for reliable wire-to-board and board-to-board interconnections. Part of the esteemed KK 254 connector system, it features a 2.54mm centreline pitch, making it a standard choice for a wide range of electronic applications.

Its dual-cantilever terminals ensure a stable and secure electrical connection, capable of handling up to 5A and 250V per circuit. The connector incorporates intelligent design features such as polarising header backwalls and ribs on the mating receptacles, which prevent mis-mating and ensure correct orientation during assembly. The friction-lock mechanism between headers and receptacles provides a secure mechanical fit without the need for additional latching hardware.

Constructed from high-temperature PA Polyamide (Nylon), the header is suitable for environments with elevated thermal demands. The contacts are crafted from brass and feature a reflow-compatible matte tin (Sn) plating, offering excellent solderability and corrosion resistance for long-term reliability. This vertical, through-hole header is supplied unshrouded for maximum flexibility in compact designs.
