Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm plating thickness, contact material grade, and insulator color variants. Ensure compatibility with target PCB board thickness specifications before procurement. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Cross-reference the full part number to avoid confusion with similar series components.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for high-current applications up to 5 A. Consider the 305 series for its panel mount versatility and wide operating temperature range. Evaluate the wire hole termination method against available assembly tools. Compare against alternative EDAC series if different mounting styles or contact configurations are needed for the specific system architecture.

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. Similar models include the 305-048-500-201 and 305-048-500-278, which share the same pitch and position count but may differ in housing color or specific termination details. The 305 series is widely used in industrial and commercial electronics for modular connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC lineup include part numbers such as 305-048-500-201 and 305-048-500-278, provided they match the required pin count and pitch. Verify that any replacement maintains the same dual-edge female configuration and current rating. Cross-check mechanical dimensions and mounting style compatibility with the existing design.
