Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct termination style, flange characteristics, and insulation color. Confirm that the required PCB thickness falls within the specified operational range of 1.37 mm to 1.78 mm. Check RoHS compliance status directly with the supplier or manufacturer documentation prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required. Ensure the application environment stays within the -40°C to +105°C operating temperature range. Verify that the mating card thickness aligns with the connector's acceptance specifications. Consider the 5 A current rating for power distribution needs and confirm compatibility with existing panel mounting requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-050 variant specifically provides 50 positions across two rows. This series is engineered for durability and consistent electrical performance in industrial and commercial electronic assemblies requiring secure board-to-board or board-to-panel connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 50-position dual-row configurations and 3.96 mm pitch, such as 305-050-500-202 or 305-050-556-208, provided flange and termination details match the design requirements.
