Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm contact plating and termination style. Ensure the selected variant matches the required row count and pitch for your PCB layout. Cross-reference the manufacturer datasheet for mechanical dimensions and mating partner specifications before finalizing procurement decisions.

Headers, Male Pins Selection Notes

Select this component when a double-row male header with a 2 mm pitch is required. Verify that the 1.0 A current rating and 500 V voltage rating meet circuit requirements. Confirm compatibility with mating female sockets and check available lead times for production scheduling.

Headers, Male Pins Part Context

This part belongs to the M22 series, which offers various configurations including single and double rows with different pitches. The M22-2021846 specifically addresses applications needing 36-position double-row connectivity with gold-plated contacts for enhanced durability and conductivity in demanding environments.

Headers, Male Pins Replacement Considerations

Check Harwin's official documentation for direct substitutes within the M22 series. Consider variants with tin plating or different row counts if gold plating is not strictly necessary. Verify mechanical compatibility with existing PCB footprints and mating connectors.
