Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with required polarizing key types before procurement. Confirm that the target printed circuit board thickness matches the 1.57 mm design parameter for proper mechanical engagement.

Edgeboard Connectors Selection Notes

Select this model when a 76-position dual-edge connector is required for panel mounting applications. It is suitable for designs needing robust polarization features and high voltage isolation. Verify that the 3.96 mm pitch aligns with the existing board layout constraints and that the 5 A current rating meets the system's electrical load requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and its ability to handle significant voltage ratings. It serves as a reliable interconnect solution for rigid board-to-board or board-to-panel interfaces in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for alternative position counts or pitch variations. Verify mechanical dimensions and electrical ratings against datasheets before substituting with other manufacturers' components.
