Molex KK 254 7478 Wire-to-Board Pin Header, Right Angle, 2 Contact, 2.54 mm

The Molex KK 254 7478 Wire-to-Board Pin Header is a 2-contact, right-angle connector with 2.54 mm pitch, designed for reliable wire-to-board interfacing on printed circuit boards.

Overview

The header is part of the KK 254 connector system and features a high-temperature nylon housing for durability and stability across a range of operating environments. Polarising ribs and back walls on the housing support correct, foolproof mating and help prevent accidental reverse insertion during assembly. The shrouded design offers additional protection for the pins and helps guide the mating connector.

Key Features

• Friction lock mechanism with integrated ramps on the housing, providing a firm, vibration-resistant hold when mated with its corresponding receptacle
• Brass contacts finished with gold plating
• Locking tangs on the terminals for added retention within the housing
• Reflow Process Compatible (RPC), suitable for automated soldering processes
• Reflow matte tin plating on the PCB tails to enhance solderability

Mounting and Design

Designed for through-hole PCB mounting, the right-angle configuration allows compact, space-saving designs where board space is at a premium or where a horizontal connection is required. The single row provides two contacts at 2.54 mm pitch.

This pin header suits polarised, friction-locked wire-to-board connections that use gold-plated brass contacts on through-hole PCBs.
