Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct termination type and mounting variations. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory requirements may vary by region and production batch. Cross-reference the part number with the latest datasheet to validate electrical ratings and mechanical dimensions before integration into design specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 12 positions and 3.96 mm pitch is required. Ensure the target PCB thickness matches the 1.57 mm specification for proper engagement. Consider the panel mount vertical orientation for space-constrained enclosures. Verify that the 5 A current rating and operating temperature range meet the application's environmental and electrical demands.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, maintaining consistent 3.96 mm pitch and 3.56 mm row spacing across models. The 305 series is designed for high-reliability applications in industrial and commercial environments, providing stable connections for dual-edge cards.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-012-556-204 and 305-012-556-278, which share similar mechanical and electrical characteristics but may differ in termination style or packaging. Always verify pinout compatibility and physical dimensions before substitution.
