Engineering Selection Recommendations

The AZ23C47-7-F is a direct electrical and mechanical substitute for the AZ23C47-7. Both parts share identical electrical specifications, configuration, and package type.

Key Distinction:

The AZ23C47-7-F is currently in active production status, whereas the AZ23C47-7 is discontinued. The AZ23C47-7-F also carries ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain identical moisture sensitivity levels and regulatory status under REACH and ECCN classifications.

The primary difference between the two parts is packaging format: the AZ23C47-7-F is supplied in Tape & Reel format, while the AZ23C47-7 is supplied in bulk. This packaging difference does not affect electrical performance or mechanical compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the AZ23C47-7-F replace the AZ23C47-7 in existing designs?

A: Yes. The AZ23C47-7-F is electrically and mechanically equivalent to the AZ23C47-7. All electrical parameters, including Zener voltage, tolerance, power rating, impedance, and operating temperature range are identical. The SOT-23-3 package dimensions and pin configuration are identical, enabling direct substitution on printed circuit boards.

Q: What is the difference between the AZ23C47-7 and AZ23C47-7-F?

A: The parts are electrically identical. The primary differences are product status and packaging format. The AZ23C47-7-F is in active production and supplied in Tape & Reel format, while the AZ23C47-7 is discontinued and supplied in bulk. The AZ23C47-7-F also carries ROHS3 compliance.

Q: Are there any compliance differences between these parts?

A: The AZ23C47-7-F is ROHS3 compliant, while the AZ23C47-7 is RoHS non-compliant. Both parts are REACH Unaffected and classified under ECCN EAR99. If RoHS compliance is required for your application, the AZ23C47-7-F is the appropriate selection.

Q: Does the Tape & Reel packaging of the AZ23C47-7-F affect circuit performance?

A: No. Tape & Reel packaging is a supply format used for automated assembly processes. It does not affect the electrical characteristics or performance of the component once mounted on the circuit board.

Q: What is the operating temperature range for both parts?

A: Both the AZ23C47-7 and AZ23C47-7-F operate across a temperature range of -65°C to 150°C, ensuring compatibility across industrial and commercial temperature specifications.

Q: Are the moisture sensitivity levels the same?

A: Yes. Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
