Headers, Male Pins Procurement Notes

Verify component obsolescence status prior to procurement as the lifecycle is listed as obsolete. Confirm regional availability restrictions with distributors. Ensure compatibility with mating sockets within the M20 series specifications. Validate that the right-angle form factor aligns with mechanical design constraints. Check for alternative sourcing channels if standard distribution is unavailable.

Headers, Male Pins Selection Notes

Select this component when a high-density 50-position connection is required in a horizontal orientation. The 2.54 mm pitch ensures compatibility with standard PCB spacing. Gold plating is preferred for environments requiring corrosion resistance. Consider the right-angle profile for vertical clearance limitations. Verify that the through-hole solder tail length meets board thickness requirements.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a family of rectangular connectors designed for general-purpose electronic applications. The series offers various configurations including vertical and horizontal headers with different position counts. The M20-9742542 specifically addresses needs for robust, high-pin-count horizontal interfaces.

Headers, Male Pins Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete lifecycle status, direct replacements may require evaluating equivalent components from other manufacturers with matching 2.54 mm pitch, 50-position, dual-row, horizontal specifications.
