Procurement Notes

This component is officially discontinued and no longer in active production. Verify availability through authorized distributors or secondary market channels. Confirm RoHS compliance status and check for valid replacement alternatives before finalizing procurement plans due to end-of-life status.

Selection Notes

Select this part only if legacy compatibility with the NJM3777 series is required. Ensure system design accommodates the specific 24-EMP package dimensions and thermal requirements. Consider that discontinuation may impact long-term supply stability and future maintenance support.

Part Context

The NJM3777E3-TE2 belongs to the NJM3777 family of stepper motor drivers. It is a high-voltage version pin-compatible with earlier models like the NJM3717. The E3 suffix typically indicates lead-free and halogen-free construction compliant with environmental standards.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, direct replacements should be verified against official manufacturer notices or engineering change orders.
