Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required board thickness and termination type. Confirm that the gold plating specification meets the application's environmental requirements. Check RoHS compliance status if restricted substances are a concern for the target market. Ensure panel mounting holes align with the connector's mechanical dimensions before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted assemblies. It is suitable for applications involving PCBs with a thickness of approximately 1.57 mm. Consider the 5 A current rating and temperature range when evaluating thermal management needs. Compare against other 305 series variants if different pin counts or row configurations are needed for the specific design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting options to support diverse industry standards. The 305-034-500-278 specifically addresses the need for a 34-position dual-row connector, fitting into the broader catalog of headers and edge connectors provided by EDAC Inc. for professional engineering applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include parts with identical mechanical dimensions but differing pin counts, such as 305-032-500-204 or 305-048-500-558. Verify that any replacement maintains the same 3.96 mm pitch and dual-row configuration. Cross-reference with other manufacturers' card edge connectors only if mechanical and electrical specifications match exactly.
