Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm insulation ratings and thermal performance specifications match the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when four-channel isolation is required with a 3/1 input-output split. Ensure the system voltage aligns with the 3.15 V to 5.5 V operating range. Consider the SOIC-WB-16 footprint constraints and thermal dissipation needs during PCB layout planning.

Part Context

This part belongs to the WPME-CDIP family of digital isolators from Würth Elektronik. These components are designed to replace traditional optocouplers in modern applications requiring higher speed and reliability. The series emphasizes robust isolation capabilities for industrial and automotive-grade electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar isolation voltages and data rates. Verify that any substitute maintains the 3/1 channel configuration and SOIC-WB-16 package dimensions.
