M20-9772546

Headers, Male Pins Overview

The Harwin M20-9772546 is a 25-position single-row vertical pin header from the M20 series. It features a 2.54 mm (0.1 inch) pitch and utilizes tin-plated brass contacts for reliable conductivity. Designed for through-hole mounting, this unshrouded connector supports board-to-board and wire-to-board applications. The housing is constructed from black nylon with a UL94 V-0 flammability rating. It operates within a temperature range of -40°C to +105°C and carries a current rating of 3A per contact with a voltage rating of 750V.

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm availability status. Check for any recent product change notifications or end-of-life announcements. Ensure that the required quantity matches standard packaging specifications provided by the manufacturer. Confirm compliance requirements such as RoHS status align with project regulations before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-row, unshrouded vertical header is required for through-hole implementation. The 2.54 mm pitch is standard for general electronics, ensuring compatibility with common mating connectors. Consider the breakaway feature if variable pin counts are needed. Verify that the 3A current rating and 750V insulation withstand voltage meet the circuit's electrical demands.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, a widely used line of rectangular connectors known for their robust mechanical design and versatile mounting options. The M20 series offers various configurations including shrouded and unshrouded headers, sockets, and cable assemblies. This specific model represents the standard vertical pin header variant, providing a cost-effective solution for high-volume manufacturing applications.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 25-position, 2.54mm pitch vertical pin headers from manufacturers such as Samtec, Molex, or TE Connectivity. Ensure that replacement parts match the critical parameters: through-hole termination, tin contact finish, and similar current/voltage ratings. Verify that the physical dimensions and keying features are compatible with the existing PCB layout and mating connector interface.
