• Medical device circuit board connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm flange type and plating specifications. Ensure the target application requires the standard 0.156-inch pitch and single-row layout. Confirm RoHS3 compliance requirements match the component's environmental classification before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a 40-position single-row interface is required for vertical mounting. The 0.156-inch pitch accommodates standard board widths. Verify that the operating environment stays within the -40°C to +105°C range. Consider the 3A current rating for power distribution needs alongside signal lines.

Edgeboard Connectors Part Context

This component belongs to the EDAC 387 Series, which provides standardized card edge connectors. The series offers various position counts and row configurations. The 387-040 variant specifically addresses high-density single-sided connection needs in compact electronic assemblies requiring robust mechanical retention.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the 387 series for alternative pin counts. Check for compatible dual-row versions if higher density is needed. Verify mechanical dimensions against existing PCB footprints before substituting.
