Edgeboard Connectors Procurement Notes

Verify the specific position count and mounting orientation against design requirements before procurement. Confirm that the target printed circuit board thickness falls within the specified operational limits to ensure proper engagement. Check regional availability status as distribution may vary by location. Ensure compliance with relevant environmental regulations such as RoHS standards required for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. Consider the 5 A current rating and thermal operating range for suitability in the application environment. Evaluate the straight mounting style against available panel space. Compare alternative series if different flange characteristics or board thickness tolerances are necessary for the specific assembly constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides a range of standard card edge connectors. The series typically includes various position counts and mounting styles to accommodate diverse electronic packaging needs.
