Procurement Notes
This component is officially marked as obsolete by Richtek USA Inc. and is no longer in active production. Distributors may list remaining stock, but availability is not guaranteed. Verification of part authenticity and condition is critical when sourcing from third-party sellers. Designers should initiate replacement strategies immediately due to discontinuation status.
Selection Notes
Engineers selecting this part must account for its obsolete status and limited future availability. The RT8497AGS provides a 1.4A output capability suitable for specific legacy lighting designs. Due to discontinuation, alternative components with similar electrical specifications and pin compatibility should be evaluated to ensure long-term supply chain stability and product lifecycle support.
Part Context
The RT8497AGS belongs to the RT8497 series of AC-DC offline switchers from Richtek. This series targets cost-effective and efficient LED driver solutions. The AGS suffix denotes the specific package type and performance grade within the family. As an older generation product, it represents earlier iterations of Richtek's LED driver technology before newer models were introduced.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult Richtek's official cross-reference tools or datasheets for recommended modern equivalents that match the required electrical parameters and package constraints.
