Engineering Selection Recommendations

All listed substitute parts maintain electrical and mechanical compatibility with the ZMM5232B-7 across the critical parameters: 5.6 V nominal Zener voltage, 500 mW power rating, DO-213AA package, and -65°C to 175°C operating temperature range.

Product Status Consideration: The ZMM5232B-7 is obsolete. All substitute parts from Microchip Technology are classified as Active, ensuring long-term availability and continued manufacturing support.

Compliance and Certification: All substitute parts are ROHS3 compliant and REACH unaffected. All substitute parts carry military-grade qualification under MIL-PRF-19500/127, providing enhanced reliability characteristics suitable for demanding applications.

Tolerance Selection:

±5% tolerance (JAN1N752AUR-1/TR, JANTXV1N752AUR-1/TR): Direct functional equivalent to ZMM5232B-7
±2% tolerance (JAN1N752CUR-1/TR, JANTX1N752CUR-1/TR, JANTXV1N752CUR-1/TR): Enhanced precision for applications requiring tighter voltage regulation
±1% tolerance (JAN1N752DUR-1/TR, JANTXV1N752DUR-1/TR): Maximum precision for critical voltage reference applications

Forward Voltage Characteristic: Substitute parts exhibit lower maximum forward voltage (1.1 V @ 200 mA) compared to the original part (1.5 V @ 200 mA), resulting in reduced power dissipation during forward conduction.

Frequently Asked Questions (FAQ)

Q: Can JAN1N752AUR-1/TR directly replace ZMM5232B-7 in existing designs?

A: Yes. JAN1N752AUR-1/TR maintains identical electrical specifications for Zener voltage (5.6 V), power rating (500 mW), tolerance (±5%), and package (DO-213AA). Both parts operate across -65°C to 175°C. The substitute part is Active status with military qualification.

Q: What is the difference between JAN1N752CUR-1/TR and JAN1N752DUR-1/TR?

A: Both parts are electrically identical except for tolerance specification. JAN1N752CUR-1/TR has ±2% tolerance, while JAN1N752DUR-1/TR has ±1% tolerance. The ±1% variant provides tighter Zener voltage control for precision applications.

Q: Are JANTX and JANTXV variants interchangeable?

A: JANTX and JANTXV variants with identical tolerance ratings (e.g., JANTX1N752CUR-1/TR and JANTXV1N752CUR-1/TR) are electrically equivalent. Both maintain 5.6 V nominal voltage, 500 mW power, ±2% tolerance, and DO-213AA package. Selection depends on specific military qualification requirements for the application.

Q: Does the lower forward voltage of substitute parts affect circuit operation?

A: The lower forward voltage (1.1 V vs. 1.5 V @ 200 mA) of substitute parts results in reduced power dissipation during forward conduction. This is a beneficial characteristic that does not compromise reverse Zener regulation performance. Circuit operation remains functionally equivalent.

Q: What packaging format is supplied for these substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Are all substitute parts RoHS compliant?

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