Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct flange features and termination types. Confirm that the required PCB thickness aligns with the connector's acceptance specifications. Check RoHS compliance status if restricted substances are mandated for the application environment. Ensure panel mounting hardware compatibility with the specified flange diameter before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this model when a high-density dual-edge connection is required for 0.062-inch thick boards. The 0.156-inch pitch allows for substantial trace routing compared to finer pitches. Consider the 5 A current rating for power distribution needs. Verify that the green thermoplastic housing meets environmental requirements. Ensure the panel mount style fits the mechanical enclosure constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations to support diverse electronic assembly needs. The 305 series is characterized by its reliability in industrial and commercial applications, providing stable electrical connections through precise contact engineering and durable housing materials.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series datasheet for cross-reference options. Identify alternatives with matching 0.156-inch pitch and 70-position dual configurations. Verify identical PCB thickness acceptance and current ratings. Ensure compatible flange features for direct replacement without mechanical modification.
