Procurement Notes

Verify component status as this part is officially listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets, noting that lead times may be extended. Ensure compliance with RoHS specifications and check for any relevant Product Change Notices or temporary certification suspensions prior to procurement.

Selection Notes

Select this component for applications requiring CRM-based PFC control in high-voltage environments. Consider the wide operating temperature range suitable for industrial conditions. Evaluate the 16-SOIC package constraints against board space requirements. Note that the device is discontinued; assess long-term supply stability and potential obsolescence risks for production integration.

Part Context

This component is part of the MC33368 series manufactured by onsemi. It falls under the category of Power Factor Correction controllers within the broader PMIC classification. The specific DR2G suffix indicates surface mount packaging in SOIC-16 format. It represents a specialized solution for critical conduction mode operation rather than general-purpose switching.

Replacement Considerations

The manufacturer has declared this product obsolete. No direct public substitute part numbers are confirmed in the provided documentation. Designers should consult official replacement guides or contact the manufacturer for end-of-life transition recommendations.
