Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact contact finish, flange style, and mounting orientation. Ensure the target PCB design aligns with the specified 0.156-inch pitch and dual-edge card requirements. Confirm compliance with RoHS3 standards if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a 44-position dual-row interface is required for vertical panel mounting. The 3.96mm pitch suits applications needing robust mechanical stability. Verify that the mating card thickness falls within the 1.37mm to 1.78mm range to ensure proper contact engagement and mechanical fit.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standardized card edge connectors for various industrial and commercial applications. The series offers multiple position counts and mounting options, utilizing consistent 3.96mm pitch geometry across models to simplify inventory management and design reuse.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC 305-044-521-202 or 305-044-555-508 for alternative flange or termination styles. Verify that substitute parts maintain the same 44-position count and 0.156-inch pitch to ensure mechanical compatibility.
