Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix 'R' against official Harwin documentation to confirm reel packaging specifications. Ensure compatibility with automated pick-and-place equipment due to the surface mount profile. Cross-reference the exact contact count and row configuration with the latest datasheet to prevent assembly errors during production integration.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, high-density connection is required on single-sided PCBs. The vertical orientation minimizes board footprint while allowing top-entry mating. Consider the 1.27 mm pitch constraint for trace routing density and ensure the 1 A current rating meets the thermal requirements of the target application circuit.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Archer M50 family, known for high-reliability board-to-board and wire-to-board connections. The series offers various mating heights and configurations. This specific model represents a standard 4-pin variant designed for space-constrained environments requiring robust electrical performance and durable mechanical locking.

Headers, Receptacles, Female Sockets Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1.27 mm pitch, 4-position count, SMT vertical orientation, and gold plating specifications exactly.
