MAZ31000ML Equivalent & Substitute Parts

Part Overview

The MAZ31000ML is a Zener diode manufactured by Panasonic Electronic Components, rated for 10 V nominal voltage with 200 mW maximum power dissipation. This component is designed for surface mount applications in the Mini3-G1 package configuration. The product is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAZ31000ML is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Zener voltage (Vz) must equal 10 V nominal
• Maximum power dissipation must be equal to or greater than 200 mW
• Impedance (Zzt) must not exceed 20 Ohms
• Reverse leakage current must not exceed 200 nA @ 7 V
• Forward voltage drop must not exceed 900 mV @ 10 mA

Mechanical Compatibility Criteria:

• Package must be TO-236-3, SC-59, or SOT-23-3 (equivalent surface mount configurations)
• Mounting type must be surface mount

The BZX84-A10,215 from Nexperia USA Inc. satisfies all electrical and mechanical substitution criteria. This part maintains the same nominal zener voltage, impedance specification, and reverse leakage characteristics while offering improved power rating (250 mW versus 200 mW) and tighter voltage tolerance (±1% versus ±6%). The package configuration is directly compatible.

Engineering Selection Recommendations

Primary Substitute: BZX84-A10,215

The BZX84-A10,215 is the recommended substitute for the obsolete MAZ31000ML. This selection is based on the following factors:

Product Status: The BZX84-A10,215 is classified as active, ensuring continued availability and supply chain stability compared to the obsolete MAZ31000ML.

Compliance and Certification: The BZX84-A10,215 carries AEC-Q101 automotive qualification and is ROHS3 compliant, providing enhanced reliability documentation and regulatory compliance suitable for production environments.

Electrical Performance: The substitute part exceeds the minimum electrical requirements of the original part. The 250 mW power rating provides a 25% margin above the 200 mW specification of the MAZ31000ML. The ±1% voltage tolerance is superior to the ±6% tolerance of the original part, resulting in tighter voltage regulation characteristics.

Package Compatibility: Both parts utilize identical TO-236-3/SC-59/SOT-23-3 surface mount packaging, enabling direct board-level substitution without layout modifications.

Electrical Characteristics: All critical electrical parameters—zener voltage, impedance, reverse leakage current, and forward voltage drop—are identical between the two parts, ensuring functional equivalence in circuit operation.

Frequently Asked Questions (FAQ)

Q: Can the BZX84-A10,215 be used as a direct replacement for the MAZ31000ML in existing designs?

A: Yes. The BZX84-A10,215 meets or exceeds all electrical specifications of the MAZ31000ML and uses the same surface mount package. No circuit modifications are required for substitution.

Q: What is the significance of the improved power rating (250 mW vs. 200 mW) in the substitute part?

A: The higher power rating provides additional thermal margin in the application. This does not change circuit operation but allows the substitute part to dissipate more heat without exceeding maximum junction temperature limits. The part will operate identically to the original in circuits designed for 200 mW operation.

Q: Does the tighter voltage tolerance (±1% vs. ±6%) affect circuit compatibility?

A: The tighter tolerance of the BZX84-A10,215 provides improved voltage regulation accuracy. Circuits designed to tolerate the ±6% tolerance of the MAZ31000ML will operate within specification with the ±1% tolerance of the substitute part. This represents an improvement in performance characteristics.

Q: Are there any package considerations when substituting these parts?

A: Both parts use the TO-236-3/SC-59/SOT-23-3 surface mount package. Footprint, lead spacing, and mounting requirements are identical. No PCB layout changes are necessary.

Q: What certifications does the substitute part carry?

A: The BZX84-A10,215 is AEC-Q101 qualified for automotive applications and ROHS3 compliant. These certifications provide additional assurance of manufacturing quality and environmental compliance compared to the obsolete MAZ31000ML.

Q: Why is the MAZ31000ML classified as obsolete?

A: The MAZ31000ML is no longer in active production by Panasonic Electronic Components. The BZX84-A10,215 represents the current-generation equivalent from an active manufacturer, ensuring long-term availability and supply chain continuity.
