Specialized Procurement Notes

Verify current lifecycle status as the component is marked NRND (Not Recommended for New Designs). Confirm availability through authorized distributors as stock may be limited. Ensure ordering quantities align with reel packaging requirements specified by the manufacturer. Check for any updated discontinuance notifications before finalizing procurement plans.

Specialized Selection Notes

Select this component only for existing designs or maintenance upgrades where the BU7620GUW-E2 is already specified. Consider alternative active parts for new developments due to the NRND status. Verify that the BGA-35 footprint matches the target PCB layout. Ensure system requirements align with the monaural configuration and I2S interface compatibility.

Specialized Part Context

The BU7620GUW-E2 belongs to the BU7620GUW series of audio CODECs from ROHM Semiconductor. It serves as a specialized interface solution for converting between digital audio streams and analog signals in a single channel configuration. The E2 suffix denotes compliance with specific environmental regulations. This part is distinct from other series like the BU7625GUW or BU7620MUV which may offer different pinouts or features.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, direct replacements should be evaluated based on functional equivalence and package compatibility. Consult ROHM Semiconductor for recommended next-generation alternatives.
