Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific variant matches the required 0.635 mm pitch and two-contact configuration. Confirm through-hole straight mounting compatibility with the target PCB layout. Ensure gold plating specifications meet the application's conductivity requirements. Check insert depth tolerance against mating component dimensions.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a low-profile, two-row header with fork contacts is required. The 0.635 mm pitch suits standard spacing needs. Through-hole installation provides mechanical robustness. Gold plating offers superior corrosion resistance compared to tin variants. Consider the 1.55 mm insert depth for mating height constraints.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the BL 2 series by Fischer Elektronik, which specializes in stamped contact springs. The series is characterized by fork contact designs optimized for specific separable pitches. These connectors are widely utilized in the electrical and electronic industries for stable board-to-board linking.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, two-row, two-contact configuration, and through-hole straight mounting. Verify identical fork contact geometry and gold plating thickness. Mating force and insert depth tolerances should be comparable to ensure interchangeability without redesign.
