Procurement Notes
This component has reached end-of-life status and is officially discontinued by the manufacturer. Availability is strictly limited to existing surplus stock from authorized distributors or third-party suppliers. Buyers must verify part authenticity and storage conditions carefully due to potential age-related degradation. No new production units are available; alternative sourcing requires rigorous quality assurance checks before integration into designs.
Selection Notes
Engineers should evaluate this part only if legacy compatibility is required, as it is no longer in active production. Designers seeking long-term supply stability should consider newer generations from the same family or equivalent modern alternatives that offer improved efficiency or extended availability windows. Verify pinout compatibility if substituting within the ISL9768x series.
Part Context
The ISL97682 belongs to the ISL9768x series of LED drivers from Renesas (formerly Intersil). This series includes variants with different channel counts and current capabilities, such as the ISL97686 and ISL97687. These components share similar architectural foundations but differ in specific output configurations and performance metrics tailored for various lighting form factors.
Replacement Considerations
Official substitutes are not explicitly listed in public discontinuation notices. Engineers may explore other members of the ISL9768x family, such as the ISL97686IBZ-T or ISL97687IRTZ, depending on channel count requirements. Cross-referencing with current Renesas LED driver portfolios is recommended for functional equivalents.
