Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB thickness standards before procurement. Confirm RoHS compliance status through the manufacturer's latest certification documents rather than relying on general product descriptions.

Edgeboard Connectors Selection Notes

Select this model when a 72-position dual-edge interface is required with a 3.96 mm pitch. Verify that the application environment stays within the specified -40 C to +105 C operational limits. Ensure the mating card edge thickness aligns with the connector's design specifications for proper mechanical engagement and electrical contact.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-072-520-278 specifically addresses high-density connection needs requiring robust mechanical locking and consistent electrical performance in demanding industrial environments.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers such as 305-072-520-204 or 305-072-521-201 for similar 72-position configurations. Verify that alternative parts match the required pitch, row count, and termination style before substitution.
