Molex KK 254 Series Straight Through Hole Pin Header 4 Contacts 2.54 mm Pitch 1 Row Unshrouded 171856-0004

Molex 171856-0004 KK 254 Series Straight Through Hole Pin Header is designed for electronic applications requiring reliable PCB connectivity. It features 4 male contacts arranged in a single row with a 2.54 mm pitch, providing compatibility for board-to-board and wire-to-board connector systems.

The pin header is constructed from brass contact material with tin plating, which prevents tin whiskering and ensures longevity and stable electrical performance. Its through-hole mount type and straight orientation allow for sturdy mechanical and electrical connections, making it ideal for various electronics assembly tasks.

This header supports up to 4 amperes of current and 250 volts, meeting the demands of many industrial and commercial electronics circuits. It operates reliably across a temperature range from -40° to 105°C, offering durability in harsh environments.

The termination type is solder, providing secure and stable solder joints with PCB pads. Being unshrouded and male gender, the pin header enables flexible and accessible connection points for external wiring or mating connectors.

These headers are KK 254 Reflow Process Compatible (RCP) friction lock style, which withstands reflow soldering temperatures up to +260°C and eliminates drying requirements typical of nylon. A recommended PCB thickness of 1.60 mm ensures optimal fit and function.

Brass contacts with tin plating ensure excellent conductivity and corrosion resistance. Through-hole mount and straight orientation provide reliable board integration. Rated for 4A current and 250V voltage, suitable for diverse electrical applications.

Wide operating temperature range from -40°C to 105°C accommodates industrial conditions. Unshrouded male contacts facilitate wiring and connector compatibility. KK 254 RCP friction lock headers withstand high reflow soldering temperatures.

Ideal for industrial, commercial, and electronic manufacturing environments requiring PCB headers. Explore more products in the PCB Headers category for advanced electronics assembly solutions and connectivity components at EnvMart.
