Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact flange and termination variations. Ensure compatibility with target PCB thickness limits before finalizing procurement orders. Cross-reference RoHS compliance status with current regulatory requirements for the destination market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 56-position interface is required for vertical panel mounting. Confirm that the application environment remains within the -40°C to +105°C operating range. Validate that the mating card edge thickness falls within the 1.37 mm to 1.78 mm specification window to ensure proper mechanical engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options. The 305-056-556-568 variant specifically addresses high-density connection needs with its 56-position layout while maintaining standard industrial form factors.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with differing position counts or flange configurations. Verify pinout and dimensional compatibility before replacing with alternative manufacturers' components.
