Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm current lifecycle status and availability. Ensure that the required contact length and stacking height match the target assembly specifications. Cross-reference the tin plating thickness if environmental resistance is critical. Confirm RoHS compliance requirements with the supplier prior to ordering.

Headers, Male Pins Selection Notes

Select this component when a vertical, double-row header with a 2.54 mm pitch is required. Consider the cuttable feature if variable row lengths are needed. Evaluate the 3A current rating against circuit demands. Compare physical dimensions against available PCB space and mating connector constraints.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used family of 2.54 mm pitch connectors. The series offers various configurations including single and double rows, vertical and right-angle options. The M20-9952646 specifically represents a double-row vertical variant, providing a balance of density and mechanical stability for standard PCB applications.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other Harwin M20 series headers with identical pitch and row count but different contact counts or orientations. Verify compatibility with mating sockets before substitution.
