Edgeboard Connectors Procurement Notes

Verify the specific termination type against official datasheets, as variations exist between solder lug and pin configurations within this series. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the ordering suffix matches the required contact finish and mounting style to avoid functional mismatches during assembly.

Edgeboard Connectors Selection Notes

Select this component when a 42-position dual-row interface is required for panel mounting. The 3.96 mm pitch accommodates standard board thicknesses of 1.57 mm. Consider the 5 A current rating and operating temperature range to ensure compatibility with the target application's electrical and environmental demands before finalizing the 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 styles, providing flexibility for different board densities. The 305-042-520-503 specifically addresses needs for higher-density connections in panel-mounted architectures.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 series variants such as 305-042-500-504 or 305-042-520-504 for potential substitutes. Verify that alternative parts match the exact position count, pitch, and mounting style to ensure mechanical and electrical compatibility without redesigning the host panel.
