Procurement Notes

This component is officially marked as obsolete and is no longer manufactured by Nisshinbo Micro Devices Inc. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Due to its discontinued status, lead times may be unpredictable, and long-term supply availability cannot be guaranteed. Verify part markings and datasheet revisions carefully before integration into new designs.

Selection Notes

Engineers requiring a replacement should evaluate current-generation unipolar stepper motor drivers from Nisshinbo Micro Devices or other manufacturers. Consider factors such as operating voltage range, current capacity, and interface compatibility when selecting a modern substitute. Review updated datasheets to ensure the alternative component meets the specific performance requirements of the target application.
