Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to ensure compatibility with system requirements. Confirm that the 28-position configuration and 3.96 mm pitch align with the target PCB layout. Check current availability status as distribution may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount card edge interface is required for 28 signals. Ensure the mating card thickness falls within the specified tolerance for the 1.57 mm nominal dimension. Consider the 5 A current rating and operating temperature range for environmental suitability.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, providing standardized interconnect solutions for dual-sided cards. The 305-028 variant specifically addresses applications requiring a compact 28-pin interface with robust mechanical stability.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 305-series headers with matching 28-position configurations and 3.96 mm pitch. Verify that any alternative maintains the same vertical panel mount style and compatible PCB thickness specifications.
