Procurement Notes

This component is designated as Not Recommended for New Designs (NRND). Procurement is restricted to supporting existing customers only; it is not available for new design implementations. Verify supply status and lead times carefully before finalizing any legacy system maintenance plans.

Selection Notes

Engineers should select the BD5246G-1 as a replacement for new designs due to its recommended status and similar pinout. The alternative offers comparable functionality with updated manufacturing support. Ensure that the transition accounts for differences in output types and current specifications between the legacy and replacement parts.

Part Context

The BD53E46G-TR belongs to the BD53 series of voltage detectors from ROHM Semiconductor. This series is characterized by adjustable delay timers and CMOS outputs. The specific model is intended for legacy support rather than new product development, reflecting a shift towards newer generation components like the BD52 series for future applications.

Replacement Considerations

BD5246G-1 is the officially recommended replacement with the same pinout and package.
