Headers, Male Pins Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm compatibility with your design requirements. Ensure that the through-hole mounting style and unshrouded configuration align with your PCB layout constraints. Cross-reference technical specifications such as current ratings and material composition with authorized distributor datasheets before finalizing procurement decisions.

Headers, Male Pins Selection Notes

Select this component when a compact, single-row header is required for low-to-medium density connections. The 2.54 mm pitch offers standard spacing compatibility with common mating connectors. Consider the unshrouded design for space-constrained applications where housing bulk must be minimized while maintaining robust mechanical retention through soldering.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, a widely utilized line of rectangular connectors known for reliability in various electronic assemblies. The M20 series provides multiple row and contact options, allowing engineers to scale connectivity needs efficiently. As a male pin header, it serves as the counterpart to female socket connectors, facilitating modular system designs.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 2-position, 2.54 mm pitch headers from manufacturers like Samtec or Molex, provided they match the through-hole mounting style and current/voltage ratings. Verify that alternative parts maintain similar insulation materials and contact plating specifications to ensure equivalent performance.
