Molex KK 254 Series Straight Through Hole Pin Header 2 Contact 2.54 mm Pitch 1 Row Unshrouded 171856-0002

Molex 171856-0002 KK 254 Series Straight Through Hole Pin Header is a precision-engineered connector designed for efficient and reliable electronic PCB interconnections. With 2 male contacts spaced at a 2.54 mm pitch in a single row, this connector is widely suited for board-to-board and wire-to-board applications in electronic manufacturing, testing, and repair.

The housing is made from high temperature thermoplastic materials, enabling the header to withstand reflow soldering processes up to +260°C without degradation. The brass contacts plated with tin minimize tin whisker formation and enhance long-term electrical performance.

This pin header connector features through-hole mounting, ensuring firm physical and electrical bonding to PCB substrates. Its male, unshrouded pins measure 2.34 mm in tail length, facilitating consistent solder joints and mechanical strength. The header is rated for voltages up to 250V and continuous currents of 4A, with operating temperatures ranging from -40°C to 105°C, making it suitable for demanding industrial and commercial electronics.

This product does not carry specific industry standards or approvals but meets quality benchmarks expected for professional electronic components. Typical use cases include electronics assembly, prototyping, telecom equipment, and instrumentation.

Features 2 male contacts with 2.54 mm pitch in a single row configuration. High temperature thermoplastic housing for durability and reflow compatibility. Brass contacts with tin plating to prevent corrosion and improve conductivity.
