Audio Special Purpose Procurement Notes

This component has reached End-of-Life (EOL). ROHM Semiconductor has issued a discontinuance notification, indicating the part will be obsolete and production will cease. Availability is limited to existing stock or last-time buys through authorized distributors. Designers should initiate replacement strategies immediately.

Audio Special Purpose Selection Notes

Select this component only for maintenance or repair of existing designs, as it is no longer recommended for new designs due to EOL status. The 2.7V to 3.6V supply range suits battery-operated or low-power designs. The VBGA035W040 package offers a compact solution for space-constrained boards. Verify thermal performance within the -20°C to +85°C range against the final system's environmental conditions.

Audio Special Purpose Part Context

This part belongs to the BU7625 series of audio codecs from ROHM Semiconductor. It is specifically designated as the GUW variant, indicating the 35-VFBGA package type. The suffix E2 typically denotes environmental compliance features, such as lead-free composition, consistent with modern manufacturing standards for electronic components.

Audio Special Purpose Replacement Considerations

Consult official ROHM documentation for verified pin-to-pin compatible alternatives. Cross-reference specifications such as supply voltage, interface type, and package dimensions before substituting. Generic audio codecs may not offer identical signal processing features or form factors.
