Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure compatibility with required polarizing key configurations and termination styles. Confirm that the selected variant matches the intended PCB thickness and mounting orientation. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and technical specifications before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 70 positions is required for panel-mounted installations. Ensure the design accommodates the 3.96 mm pitch and 1.57 mm board thickness constraints. Consider the 5 A current rating and thermal operating limits when defining system electrical requirements. Verify that the housing color and material properties align with environmental protection needs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standardized solutions for card edge applications. The series includes various position counts and row configurations to support diverse electronic assembly needs. Components in this family share common mechanical dimensions and contact spacing standards, facilitating modular design approaches across different product lines.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include models such as 305-070-520-204 and 305-070-521-258. These alternatives maintain identical positional and dimensional characteristics while potentially differing in housing color or specific accessory configurations. Verify exact pinout and mechanical fit before substitution.
