M22-2521305

Headers, Male Pins Overview

The M22-2521305 is a vertical pin header connector from the Harwin M22 series, designed for board-to-board applications. It features a 2mm pitch and comprises 26 positions arranged in a single row. The connector utilizes through-hole termination for secure PCB mounting. Contacts are constructed from phosphor bronze with gold plating to ensure reliable signal transmission. The housing is made of black polyamide (PA6T) material rated UL94 V-0 for flame resistance. It operates within a temperature range of -40°C to +105°C and carries a current rating of 1A per contact.

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm availability and lead times. Ensure compatibility with mating socket connectors regarding pitch and housing dimensions. Check for RoHS compliance requirements if operating in regulated environments. Confirm that the through-hole mounting style aligns with the assembly process capabilities of the manufacturing facility.

Headers, Male Pins Selection Notes

Select this component when a vertical, single-row header with a 2mm pitch is required for board-to-board connections. Consider the 1A current rating and -40°C to +105°C operating temperature range for suitability in the intended application environment. Verify that the 26-position count matches the design specifications and that the through-hole installation method is compatible with the PCB fabrication process.

Headers, Male Pins Part Context

This component belongs to the Harwin M22 series, which offers various configurations including single and double rows with different contact counts. The series is known for its compact design suitable for increasing PCB density while maintaining height restrictions. Other variants in the series may differ in row count, position numbers, or termination styles such as surface mount options.

Headers, Male Pins Replacement Considerations

Consult official Harwin resources for direct substitute part numbers within the M22 series that match the required position count and pitch. Generic replacements should be evaluated carefully to ensure identical dimensional constraints and electrical characteristics. Verify that any alternative maintains the same UL94 V-0 rating and temperature performance.
