Molex KK Plus 250 Series Straight Through Hole PCB Header, 4 Contacts, 2.5 mm Pitch, 1 Row, Shrouded, 6.5A, 250V 207843-0004

The Molex 207843-0004 KK Plus 250 Series PCB Header is a high-quality straight through hole connector designed for secure and reliable wire-to-board connections in demanding electronic and industrial environments. With a fully shrouded housing, this header supports up to four contacts arranged in a single row, maintaining a compact form factor while providing robust electrical performance.

Featuring a 2.5 mm pitch between contacts, the header delivers flexibility for circuit designers and ensures compatibility with a wide range of Molex and other connector systems. The orientation is straight and vertical, making it suitable for applications where space-saving and efficient alignment are essential. The housing is constructed from liquid crystal polymer, providing excellent insulation resistance and thermal stability, while the contacts are manufactured from brass and finished with tin plating for optimal conductivity and long-lasting durability.

The 207843-0004 header is rated for 6.5A current and up to 250V voltage, making it suitable for both power and signal transmission in instrumentation, industrial controls, consumer electronics, and automotive devices. The solder termination type simplifies integration into PCB assemblies, and the recommended PCB thickness is 1.6 mm for optimal mechanical stability. An operating temperature range from -40°C to 105°C allows the connector to perform consistently in a variety of environmental conditions, from laboratories to harsh industrial sites.

Designed with male contacts and a wire-to-board connector system, this product is ideal for applications requiring secure mating and reliable interconnects. The shrouded design helps prevent misalignment and accidental damage, improving the lifespan and integrity of electronic assemblies. The product complies with international standards for safety and performance, though no explicit certifications such as RoHS are stated.

Common use cases include industrial automation, robotics, measurement instrumentation, telecommunications, automotive electronics, and advanced consumer devices. The Molex KK Plus 250 Series is recognized for its dependability and is widely used in manufacturing, installation, maintenance, and prototyping workflows.
