Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm availability status and regional distribution restrictions. Ensure that the procurement channel sources genuine components directly from authorized distributors or the manufacturer to maintain quality standards. Cross-reference the datasheet specifications with system requirements prior to ordering.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required for panel-mounted applications. Confirm that the host PCB thickness aligns with the specified 1.57 mm acceptance range. Verify that the environmental conditions fall within the -40°C to +105°C operational limits and that the 5 A current rating meets the circuit demands.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and configurations for standard card edge applications. The series is characterized by its robust construction and compatibility with polarizing keys. Similar models in the lineup may differ in pin count or row configuration while maintaining consistent interface dimensions and material properties.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants such as 305-018-521-503 and 305-018-521-208. These parts share identical mechanical dimensions and contact spacing but may differ in housing color or specific termination details. Always validate cross-references using official manufacturer data sheets before implementation.
