Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact plating thickness and insulation material specifications. Ensure compatibility with the target PCB board thickness limits before procurement. Confirm RoHS compliance status through the latest certified documentation provided by EDAC Inc. for regulatory adherence.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 28-position interface with a 3.96 mm pitch is required. Consider the vertical panel mount style and solder pin termination method for assembly constraints. Evaluate the operating temperature range and current rating against system thermal and electrical loads to ensure long-term reliability under expected conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their thermoplastic polyester construction and copper alloy contacts. The series offers various position counts and mounting styles, providing a modular solution for connecting edge-board modules to backplanes or chassis-mounted headers in electronic assemblies.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination types. Verify mechanical footprint and electrical ratings match before substituting with other manufacturers' products offering similar 3.96 mm pitch specifications.
