Headers, Male Pins Procurement Notes

Verify the specific suffix and packaging quantity when ordering, as distribution channels may offer different reel sizes or tape configurations. Confirm that the requested variant matches the through-hole vertical orientation and 16-position count. Cross-reference the manufacturer part number with official Harwin documentation to ensure compatibility with mating sockets. Check for any regional supply restrictions or lead time variations before finalizing procurement plans.

Headers, Male Pins Selection Notes

Select this component when a double-row, 2.54mm pitch male header is required for through-hole assembly. Ensure the mating socket provides compatible push-pull locking if mechanical retention is necessary. Verify that the PCB layout accommodates the specified contact length and insulation height. Consider the 3A current rating per contact for thermal management in high-density applications.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, which offers a range of rectangular connectors for various mounting styles. The M20-9720845 specifically addresses needs for vertical, double-row headers with through-hole termination. It complements other M20 series components like sockets and single-row headers, providing modular solutions for electronic interconnects.

Headers, Male Pins Replacement Considerations

Compatible substitutes include M20-9720842R for surface mount variants, though mounting style differs. For identical through-hole specifications, verify equivalent parts from Harwin's M20 family with matching 16-position, double-row configurations. Ensure mating compatibility with existing socket designs before substitution.
