Procurement Notes
This component is classified as obsolete or discontinued by the manufacturer. Verification of current availability through authorized distributors is essential. Sourcing may be limited to surplus stock or alternative channels. Confirm end-of-life status and lead times carefully before integration into new designs.
Selection Notes
Select this part only if legacy compatibility with existing 28-LCC footprints is required. Ensure the system design accommodates the specific 4.75V to 5.25V supply voltage constraint. Consider pin-compatible alternatives from the same series if long-term supply stability is a priority for the product lifecycle.
Part Context
The NJM3774FM2 belongs to the NJM377x series of motor drivers from Nisshinbo Micro Devices. It serves as a dedicated solution for bipolar stepper motors, distinct from unipolar variants. The series includes related models such as the NJM3772 and NJM3775, offering similar functionality across different packaging or minor electrical variations.
Replacement Considerations
The NJM3774FM2-TE3 is a verified equivalent variant within the same product line. Other members of the NJM377x family may serve as functional substitutes depending on specific package and voltage requirements.
