Molex KK 254 8 Way Right-Angle Wire-to-Board Header, 2.54mm Pitch

The Molex KK 254 Connector System is a versatile and reliable solution for board-to-board and wire-to-board connections, engineered for demanding applications across multiple industries. This specific 8-way, single-row, right-angle header delivers a current rating of up to 5A and 250V per circuit, built on a standard 2.54mm centreline pitch for compatibility with common PCB layouts.

Constructed for secure and precise mating, the system features dual-cantilever terminals for a stable, gas-tight connection. Polarising header backwalls and ribs on the mating receptacles prevent incorrect insertion, ensuring foolproof assembly. Friction-lock headers and receptacles provide a positive retention mechanism without the need for additional latching hardware, simplifying the installation process.

The KK RPC headers, such as this model, are manufactured from high-temperature PA Polyamide (Nylon), offering excellent thermal and mechanical stability for reflow soldering processes and challenging operating environments. The contacts are made from brass with a reflow-compatible matte tin (Sn) plating, ensuring good solderability and reliable electrical conductivity.

Key Applications

This robust connector is specified for use in sectors where reliability is non-negotiable, including automotive electronics, consumer devices, communications networking equipment, and medical instrumentation. Its right-angle through-hole termination is ideal for creating perpendicular connections between a PCB and wiring harnesses, saving valuable board space and facilitating neat cable routing.
