Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB stack-up and mounting hole patterns. Confirm RoHS compliance status through the manufacturer's latest certification documents before integration into regulated assemblies.

Edgeboard Connectors Selection Notes

Select this model when a 46-position dual-row interface is required with a 3.96 mm pitch. Consider the 5 A current rating and 1.57 mm board thickness constraints. Evaluate the solder lug termination against available PCB layout options. Compare against the broader 305 series for alternative position counts or mounting variations.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles while maintaining consistent electrical ratings and mechanical dimensions. It serves as a robust solution for high-density interconnect applications requiring durable metal-to-metal contact interfaces.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series headers with matching 46 positions and 3.96 mm pitch, such as 305-046-556-204 or 305-046-556-278, provided the termination type and mounting style align with the design requirements.
