Procurement Notes
Verify the specific part number against official EDAC documentation to confirm compatibility with your PCB design requirements. Ensure that the ordering suffix matches the desired termination and flange specifications. Cross-reference the datasheet for mechanical dimensions and environmental ratings before finalizing procurement decisions.
Selection Notes
Select this component when a high-density connection with 40 positions is required. The 3.96 mm pitch allows for robust contact engagement on thicker boards. Consider the through-hole mounting style and straight orientation for panel or chassis integration. Verify that the operating temperature range meets the application's thermal environment.
Part Context
This connector belongs to the EDAC 306 series, which offers various position counts and mounting options. The series is designed for general-purpose card edge applications. The 306-020-520-178 variant specifically addresses needs for dual-edge connectivity with a standardized pitch. It complements other connectors in the family by providing a fixed 40-position solution.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult EDAC technical support for potential alternatives if this specific configuration is unavailable.
