Engineering Selection Recommendations

Both the EM 1V0 and EM01V1 diodes are active, RoHS compliant, and share identical electrical and mechanical parameters. Selection between these parts can be based on available packaging types and inventory levels without requiring further technical consideration regarding certifications or compliance.

Frequently Asked Questions (FAQ)

Q: On what basis can EM01V1 be considered equivalent to EM 1V0?
A: EM01V1 matches EM 1V0 in all key electrical and mechanical specifications, as well as compliance and product status.

Q: Are there any differences in performance or reliability between EM 1V0 and EM01V1?
A: No, all compared parameters including voltage, current, recovery speed, leakage, and operating temperature are identical.

Q: Does the packaging type affect substitution?
A: The main difference is the packaging: EM 1V0 is supplied in Tape & Box (TB), while EM01V1 is provided in Cut Tape (CT). Electrical and mechanical parameters remain the same.

Q: Is RoHS compliance consistent between EM 1V0 and its substitute?
A: Yes, both are RoHS compliant.

Q: Can these diodes be used interchangeably in the same PCB footprint?
A: Both parts use a through-hole, axial package, supporting direct interchangeability when packaging differences are not a concern.
