Edgeboard Connectors Procurement Notes
Verify part number accuracy against official EDAC documentation before procurement. Confirm that the specific suffix matches required mechanical and electrical specifications. Ensure compatibility with target PCB thickness and mounting style. Check current availability status as distribution may vary by region.
Edgeboard Connectors Selection Notes
Select this component when a dual-row, 78-position connection is required for thick PCBs. The 3.96 mm pitch suits high-density layouts where spacing allows. Verify that the vertical panel mount style aligns with enclosure design constraints and thermal requirements.
Edgeboard Connectors Part Context
This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent pitch and contact materials. It serves as a header for mating with double-sided edge cards in industrial and specialized environments.
Edgeboard Connectors Replacement Considerations
Direct substitutes include other EDAC 305 series variants with identical 78 positions and 3.96 mm pitch, such as 305-078-555-568. Cross-brand replacements require matching pitch, row count, and termination type.
