Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 66-position configuration and dual-edge compatibility. Confirm that the flange characteristics align with the mounting panel requirements, as variations exist within the series regarding thread types and diameters. Ensure the thermal and electrical ratings meet the system's operational demands before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required with robust polarizing key support. The 305 series provides versatile mounting options including cross-mount and panel mount styles. Verify the specific flange details against the mechanical design to ensure proper fitment and alignment during assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series includes various position counts and mounting styles, offering flexibility for different board densities. The 305-066-555-512 specifically addresses needs for 66-position dual-edge interfaces with standardized 3.96 mm spacing.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching 66-position dual-edge specifications. Verify identical pitch, current rating, and flange dimensions to ensure mechanical interchangeability without redesigning the host panel or PCB layout.
