Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm mounting style and termination type, as these parameters vary within the 305 series. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the dual-row layout meets the spatial requirements of the assembly. Cross-reference the manufacturer's current datasheet for any updates on material specifications or environmental compliance status before finalizing the procurement order.

Edgeboard Connectors Selection Notes

Select this model when a high-pin-count connection is required in a compact form factor. The 3.96 mm pitch allows for robust mechanical stability while maintaining a manageable footprint. Consider the vertical panel mount orientation if space constraints on the PCB are critical. Evaluate the thermal performance limits against the operational environment to ensure long-term reliability under load conditions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, catering to diverse electronic integration needs. The 305-084 variant specifically addresses applications requiring a large number of connections in a single interface point, providing a standardized solution for board-to-board or backplane connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with different pin counts but identical pitch and mounting characteristics. Verify that alternative models maintain the same 3.96 mm spacing and 1.57 mm board thickness acceptance. Ensure that the replacement part supports the required current rating and environmental operating range.
