Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm current availability status. Ensure that the required contact count and pitch match the application design specifications. Check for any obsolete or last-time-buy notices associated with this specific configuration before finalizing procurement plans.

Headers, Male Pins Selection Notes

Select this component for applications requiring right-angle male headers with a 1.27mm pitch. Confirm that the PCB layout supports through-hole mounting and the specified body dimensions. Verify that the 1000VAC dielectric rating meets the electrical isolation requirements of the target circuit environment.

Headers, Male Pins Part Context

This part belongs to the M50 series of connectors manufactured by Harwin Inc. The series includes various configurations such as vertical headers, surface mount options, and different contact counts. This specific model represents a right-angle, through-hole variant within that broader product family.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 1.27mm pitch, 4-position count, and right-angle through-hole form factor. Verify mechanical compatibility and electrical ratings before swapping with other manufacturers' components.
