Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm plating thickness and material specifications. Ensure compatibility with target PCB thickness ranges before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the dual-edge design matches the mechanical constraints of the intended assembly environment.

Edgeboard Connectors Selection Notes

Select this component when a 48-position dual-edge interface is required with a 3.96 mm pitch. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Verify that the 1.37–1.78 mm board thickness tolerance aligns with the PCB design specifications.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations for edgeboard applications. The 305-048 variant specifically addresses high-density connection needs within industrial and commercial electronics sectors.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 305 series prefix and 48-position count. Verify identical pitch, board thickness, and contact configuration before substitution.
