• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Vertical orientation facilitates compact vertical stacking configurations

Headers, Receptacles, Female Sockets Applications

• High-density electronic module assembly
• Industrial control system interconnections
• Telecommunications equipment backplanes

Headers, Receptacles, Female Sockets Procurement Notes

Verify the Last Time Buy status before finalizing procurement plans, as production may cease. Confirm that the specific 56-position configuration meets all mechanical and electrical requirements. Ensure compatibility with existing PCB footprints and mating header components to prevent integration issues during the final manufacturing phase.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a 1.27mm pitch SMT receptacle with 28 pins per row is required. Verify that the PBT housing material and UL 94 V-0 flammability rating align with safety standards. Ensure the 1A current rating suffices for the target application's power distribution needs without requiring parallel paths.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Archer M50 series, designed for robust surface-mount applications. It complements matching male headers within the same family. The design prioritizes space efficiency and mechanical stability in dense electronic assemblies requiring reliable vertical connectivity.

Headers, Receptacles, Female Sockets Replacement Considerations

No officially confirmed substitute part numbers are available in public documentation. Due to the Last Time Buy status, alternative sourcing should focus on compatible M50 series variants with identical pin counts and pitch specifications.
