Frequently Asked Questions (FAQ)

Q: Can the 1N5223BUR-1/TR be used as a direct replacement for the ZMM5223B-13?

A: Yes. The 1N5223BUR-1/TR maintains identical Zener voltage (2.7 V), tolerance (±5%), power rating (500 mW), impedance (30 Ohms), and operating temperature range (-65°C ~ 175°C). Both parts use the DO-213AA Surface Mount package. The forward voltage specification of the substitute is superior (1.1 V vs. 1.5 V @ 200 mA).

Q: What is the difference between the 1N5223BUR-1/TR and JAN1N4371AUR-1/TR?

A: Both parts are parametric equivalents with identical Zener voltage, tolerance, power rating, impedance, and operating temperature specifications. The JAN1N4371AUR-1/TR is military-qualified to MIL-PRF-19500/127 and exhibits lower reverse leakage current (60 µA vs. 75 µA @ 1 V). Selection between these parts depends on application requirements for military-grade certification.

Q: Are the substitute parts available in the same package as the ZMM5223B-13?

A: Yes. Both substitute parts use the DO-213AA Surface Mount package, which is mechanically and electrically compatible with the original ZMM5223B-13 Mini MELF package designation.

Q: Why is the ZMM5223B-13 listed as obsolete?

A: The ZMM5223B-13 is classified as obsolete by the manufacturer. The listed substitute parts provide equivalent electrical and mechanical functionality with active product status, ensuring continued availability for design support and production requirements.

Q: What packaging formats are available for the substitute parts?

A: Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount production environments.

Q: Do the substitute parts meet RoHS compliance requirements?

A: The ZMM5223B-13 is specified as ROHS3 Compliant. RoHS compliance information for the substitute parts is not provided in the available specifications. Compliance verification should be obtained directly from the manufacturer for specific application requirements.
