Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm the single-row configuration and gold-plated contact finish. Ensure compatibility with standard 2.54mm mating systems. Check for any recent product lifecycle updates or alternative sourcing options if availability is constrained.

Headers, Male Pins Selection Notes

Select this component when a low-profile, single-row male header is required for through-hole assembly. The 2.54mm pitch ensures broad compatibility with standard connectors. Consider the unshrouded design for applications where space is limited and mechanical retention is provided by the mating system.

Headers, Male Pins Part Context

This connector belongs to the Harwin M20 series, which provides a range of high-density interconnect solutions. The series is known for its reliability in demanding environments. The M20-9770342 specifically addresses needs for small-form-factor electronics requiring robust vertical connectivity.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 3-position, 2.54mm pitch, single-row vertical pin headers with through-hole termination. Verify that replacement parts match the current rating, temperature range, and contact material specifications.
