Substitute Part Grouping Explanation

Substitute parts for the ZMM5230B-13 are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

Zener voltage (Vz) = 4.7 V nominal
Power dissipation rating = 500 mW
Maximum impedance (Zzt) = 19 Ohms
Operating temperature range = -65°C to 175°C
Package type = DO-213AA surface mount

Tolerance Grouping: Substitute parts are organized by voltage tolerance specification, which directly affects circuit performance and design margin requirements. The ZMM5230B-13 specifies ±5% tolerance. Substitute parts with tighter tolerances (±2% and ±1%) provide enhanced precision for applications requiring stricter voltage regulation.

Military Grade Qualification: All substitute parts listed are manufactured by Microchip Technology and carry military-grade qualification under MIL-PRF-19500/127, with product status classified as Active. These parts are available in Tape & Reel (TR) packaging format.

Engineering Selection Recommendations

Primary Selection Criteria:

All substitute parts listed are manufactured by Microchip Technology and maintain Active product status, ensuring long-term availability and supply chain continuity. Each substitute part is qualified under MIL-PRF-19500/127 military specification and complies with ROHS3 and REACH standards.

Tolerance-Based Selection:

For applications requiring electrical characteristics identical to the ZMM5230B-13 (±5% tolerance), select JAN1N750AUR-1/TR or JANTXV1N750AUR-1/TR. Both parts maintain the same voltage tolerance specification while offering improved forward voltage characteristics (1.1 V versus 1.5 V @ 200 mA).

For applications where tighter voltage regulation is required, JAN1N750CUR-1/TR, JANTX1N750CUR-1/TR, JANTXV1N750CUR-1/TR offer ±2% tolerance. For maximum precision, JAN1N750DUR-1/TR, JANTX1N750DUR-1/TR, JANTXV1N750DUR-1/TR provide ±1% tolerance specification.

Military Grade Considerations:

Parts designated with "JAN" prefix meet JAN (Joint Army-Navy) specifications. Parts with "JANTX" prefix include temperature cycling qualification. Parts with "JANTXV" prefix include additional vibration qualification. Selection depends on application environmental requirements.

Packaging and Inventory:

All substitute parts are supplied in Tape & Reel (TR) format suitable for automated assembly. Inventory availability ranges from 648 to 1164 pieces across the substitute part options.

Frequently Asked Questions (FAQ)

Q: Can JAN1N750AUR-1/TR directly replace ZMM5230B-13 in existing designs?

A: Yes. JAN1N750AUR-1/TR maintains identical electrical specifications: 4.7 V nominal zener voltage, ±5% tolerance, 500 mW power rating, 19 Ohms maximum impedance, and DO-213AA package. The forward voltage is improved (1.1 V versus 1.5 V @ 200 mA), which is a beneficial characteristic change.

Q: What is the difference between JAN, JANTX, and JANTXV part designations?

A: These designations indicate military qualification levels. JAN parts meet basic Joint Army-Navy specifications. JANTX parts include temperature cycling qualification. JANTXV parts include both temperature cycling and vibration qualification. Selection depends on application environmental stress requirements.

Q: Why do substitute parts show lower forward voltage (1.1 V) compared to the original (1.5 V)?

A: Forward voltage is a measured characteristic that can vary within acceptable limits for the same part type. The lower forward voltage in substitute parts represents improved performance and does not affect substitutability for the ZMM5230B-13 application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What tolerance should I select for my application?

A: Select tolerance based on circuit design requirements. The ±5% tolerance (JAN1N750AUR-1/TR, JANTXV1N750AUR-1/TR) matches the original ZMM5230B-13 specification. Tighter tolerances (±2% or ±1%) provide enhanced voltage regulation precision for applications with stricter requirements.

Q: Is the DO-213AA package identical across all parts?

A: Yes. All parts use DO-213AA surface mount package with identical mechanical and electrical interface characteristics, ensuring direct PCB compatibility.

Q: What is the reverse leakage current specification for substitute parts?

A: Substitute parts specify 5 µA @ 1.5 V reverse leakage, compared to the original 5 µA @ 2 V. Both values represent equivalent leakage performance within acceptable operating parameters.
