Edgeboard Connectors Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm compatibility with target PCB thickness and mounting requirements. Ensure that the dual-row configuration aligns with the intended card edge design. Cross-reference the gold plating specification and current rating with system operational demands. Confirm RoHS compliance status through the latest datasheet before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel mount header is required for double-sided card edge applications. The 3.96 mm pitch suits standard board layouts requiring robust connection points. Consider the 5 A current rating and wide operating temperature range for environments subject to thermal variation. Verify that the solder pin termination method matches the available assembly processes and PCB layout constraints.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose electronic interconnections. The series offers various position counts and configurations to support diverse board densities. Components in this family typically feature durable metal contacts and stable plastic housings suitable for repeated insertion cycles in industrial and commercial hardware systems.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series headers with matching 20-position dual-row layouts and identical 3.96 mm pitch specifications. Ensure alternative parts maintain the same 1.57 mm board thickness tolerance and gold-plated contact finish. Verify that replacement units support the same vertical panel mounting style and solder pin termination method.
