Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm availability status and manufacturing lifecycle stage. Ensure that the selected component matches the required 26-position count and single-row layout for your design. Cross-reference datasheet specifications for mating heights and thermal limits before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this connector when a single-row, 26-position header is required for vertical mounting. Consider the 2 mm pitch and 1 A current rating for circuit compatibility. Verify that the 3.8 mm, 5.9 mm, or 8.6 mm mating stacking heights align with the mechanical constraints of the target assembly.

Headers, Male Pins Part Context

This component belongs to the Harwin M22 series, which offers various position counts and row configurations. The M22-2021346 specifically addresses the need for higher-density single-row connections compared to lower-position variants like the M22-2040446. It shares common material properties with other M22 headers but differs in contact count and overall dimensions.

Headers, Male Pins Replacement Considerations

Direct substitutes within the M22 series include other 26-position single-row headers such as M22-2021346 variants with different plating if available. For cross-series replacements, verify pitch, row count, and current ratings match the original design requirements.
