Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct contact plating thickness and flange specifications. Confirm that the required board thickness falls within the specified 0.054 to 0.070 inch range for proper mechanical engagement. Check regional availability as distribution status may vary by location.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position connection is required with a 3.96 mm pitch. Ensure the application environment stays within the -40°C to +105°C operating temperature limits. Consider the vertical panel mount style if space constraints require a perpendicular interface relative to the mating card.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations, all sharing common mounting styles and material properties. The 305 series is widely used in applications demanding high reliability and consistent electrical performance across diverse industrial sectors.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts such as 305-042-520-202 or 305-042-521-508 variants only if exact dimensional and electrical parameters match. Verify compatibility with existing PCB layouts and mating cards before substitution.
