Frequently Asked Questions (FAQ)

Q: Can the IUGZX1-0-91 directly replace the IUGX1-0-91?

A: Yes. Both components are AC/DC circuit breakers from Sensata-Airpax with identical MSL ratings, export classifications, and tariff codes. The IUGZX1-0-91 is the manufacturer-designated active replacement.

Q: What is the difference between these part numbers?

A: The IUGX1-0-91 is obsolete; the IUGZX1-0-91 is active. The substitute part includes RoHS compliance certification. Both maintain identical functional and regulatory parameters for AC/DC circuit breaker applications.

Q: Are there packaging differences between these parts?

A: Packaging information is not specified in the technical data for either component. Consult manufacturer documentation or contact the supplier for packaging specifications.

Q: Does the RoHS compliance of the substitute affect compatibility?

A: No. RoHS compliance represents an additional environmental certification on the substitute part and does not alter electrical or mechanical compatibility with the original component.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures.
