Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm contact plating thickness and housing material variations. Ensure compatibility with the target PCB thickness range of 1.37mm to 1.78mm before procurement. Confirm that the solder lug termination style aligns with the assembly process requirements.

Edgeboard Connectors Selection Notes

Select this model when a 28-position dual-row connector with a 3.96 mm pitch is required. It is suitable for applications demanding polarizing key integration and high dielectric strength. Consider the panel mount vertical installation style and the specific current rating constraints when designing the circuit interface.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options, all sharing a consistent 3.96 mm pitch architecture. These connectors are engineered for durability in industrial environments, providing stable electrical connections for double-sided edge cards.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for alternative position counts such as 305-028-556-204 or 305-028-556-208 if different housing materials or contact finishes are needed. Verify mechanical dimensions and pinout configurations before substituting.
