Edgeboard Connectors Procurement Notes

Verify the complete part number against official EDAC documentation to ensure correct pin count and termination style. Confirm that the target PCB thickness matches the specified 1.57 mm requirement for proper mechanical engagement. Check regional availability as distribution status may vary by location. Ensure compliance with required environmental ratings for the intended operational temperature range.

Edgeboard Connectors Selection Notes

Select this component when a high-density vertical connection is required for thick PCBs. The 3.96 mm pitch offers robust spacing for industrial environments. Verify that the 5 A current rating meets the circuit load requirements. Consider the panel mount style if space constraints prevent board-level mounting. Ensure the gold plating specification aligns with corrosion resistance needs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge interfaces. The series provides various position counts while maintaining consistent 3.96 mm spacing. The 305-074-520-508 variant specifically addresses applications requiring 74 positions. It utilizes a standardized form factor compatible with common edge card designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-070-520-508 and 305-072-520-504. These alternatives share identical pitch and mounting characteristics but differ in position count or specific tail configurations. Verify dimensional compatibility before substitution.
