Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm terminal termination style and flange characteristics. Ensure the selected variant matches the required PCB thickness tolerance and mounting orientation. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required for panels up to 0.062 inches thick. The 3.96 mm pitch allows for moderate trace density while maintaining robust mechanical engagement. Consider the vertical panel mount style and solder lug termination for through-hole assembly processes in rigid structural applications.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in panel-mount applications. The series offers various position counts and termination options, catering to diverse electronic enclosure needs. The 305-084 variant specifically addresses higher channel count requirements within this standardized family framework.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination styles. Verify compatibility with existing PCB stack-ups and mounting hole patterns when evaluating alternative part numbers within the same product family.
