Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required board thickness and termination styles. Confirm that the dual-edge configuration matches the target application's mechanical constraints. Cross-reference the part number with the latest EDAC documentation to validate material specifications and environmental ratings before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge interface is required for standard thickness boards. Ensure the system design accommodates the 3.96 mm pitch and 3.56 mm row spacing dimensions. Verify that the operating environment falls within the specified temperature range and that the 5 A current rating meets the electrical load requirements of the connected circuitry.

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 options to support diverse industrial and commercial applications. The 305 series is characterized by its robust construction and standardized dimensions, facilitating integration into modular electronic systems requiring reliable dual-sided connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 78-position count, 3.96 mm pitch, and dual-edge female configuration. Verify that alternative parts support the same 0.062 inch board thickness and solder lug termination. Consult EDAC's official cross-reference guides for verified equivalent part numbers within the same product family.
