Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact plating, row count, and termination style match project requirements. Confirm availability status as distribution channels may vary by region. Ensure the target PCB design accommodates the specified 1.57 mm board thickness and 3.96 mm pitch dimensions before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 66-position interface is required with high current carrying capacity. The 3.96 mm pitch suits applications needing wider spacing between signals. Verify that the operating temperature range of -40°C to +105°C aligns with the environmental conditions of the end application. Ensure the panel mount orientation fits the mechanical enclosure constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for robust performance in industrial and medical sectors. The series offers various position counts and configurations to support diverse electronic module designs. EDAC focuses on providing reliable interconnect solutions that withstand rigorous operational demands across multiple technology domains.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants like 305-066-556-268 or 305-066-556-508, differing primarily in contact plating or packaging. Cross-series replacements require matching the 3.96 mm pitch and 66-position count. Verify that alternative parts maintain the same vertical panel mount style and solder pin termination to ensure mechanical compatibility.
