Procurement Notes
Verify the Not Recommended for New Designs (NRND) status before finalizing any procurement plans. This designation indicates that the manufacturer does not intend to accept new design-ins for this specific part number. Existing production may continue, but long-term supply stability for new projects is not guaranteed. Confirm availability through authorized distributors and assess lead times carefully if immediate replenishment is required for existing manufacturing lines.
Selection Notes
Select this component only for legacy maintenance or specific retrofit applications where the NRND status is acceptable. Evaluate alternative ROHM LED drivers currently recommended for new designs to ensure future supply chain security. Ensure the application strictly adheres to the 60 mA output limit and 5.5 V maximum input voltage constraints to prevent device damage.
Part Context
This part belongs to the BD82103GWL series of LED lighting drivers manufactured by ROHM Semiconductor. It is categorized under LED Lighting Drivers within the broader PMIC family. The specific suffix -E2 denotes environmental compliance attributes consistent with RoHS standards. The UCSP package type allows for high-density PCB layout integration compared to larger traditional packages.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, direct cross-referencing requires consulting official ROHM replacement guides or contacting technical support for validated alternatives.
