MAZD10000L Equivalent & Substitute Parts

Part Overview

The MAZD10000L is a Zener diode manufactured by Panasonic Electronic Components, rated at 10 V nominal with 120 mW maximum power dissipation in a surface mount SSSMini2-F2 package. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements. Substitute parts must maintain electrical performance within acceptable tolerances while accommodating available packaging and supplier options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAZD10000L is determined by the following critical electrical and mechanical parameters:

Zener Voltage Compatibility: The nominal Zener voltage must fall within the tolerance band of the original specification. The MAZD10000L operates at 10 V ±6%, establishing an acceptable range of 9.4 V to 10.6 V. Substitute parts with nominal Zener voltages within this range are considered electrically compatible.

Power Dissipation: The maximum power rating of substitute parts must equal or exceed 120 mW to ensure thermal performance equivalent to the original component.

Package and Mounting: Both the main part and substitute must utilize surface mount technology with 2-SMD flat lead configuration to ensure mechanical compatibility with existing PCB layouts and assembly processes.

Impedance and Leakage Characteristics: Maximum impedance and reverse leakage current specifications must not exceed the original values to maintain circuit performance and stability.

The CDZFHT2RA10B from Rohm Semiconductor satisfies these substitution criteria and is identified as an equivalent alternative.

Parameter Comparison

Engineering Selection Recommendations

The CDZFHT2RA10B is qualified as an equivalent substitute for the obsolete MAZD10000L based on the following factors:

Electrical Compatibility: The nominal Zener voltage of 9.99 V falls within the acceptable tolerance band established by the original 10 V ±6% specification. The impedance specification of 30 Ohms matches the original component exactly.

Mechanical Compatibility: Both components utilize identical surface mount packaging (2-SMD, flat lead configuration), ensuring direct PCB layout compatibility without redesign requirements.

Product Status and Availability: The CDZFHT2RA10B is classified as "Not For New Designs" but remains in active inventory (6645 units available), providing a viable solution for legacy system support and maintenance applications.

Compliance and Certification: The CDZFHT2RA10B carries AEC-Q101 automotive qualification and RoHS3 compliance, meeting stringent reliability and environmental standards. Both components share identical ECCN and HTSUS classifications.

Design Considerations: The CDZFHT2RA10B exhibits a tighter tolerance (±2.2% versus ±6%) and lower maximum power rating (100 mW versus 120 mW). Circuit designs operating near the thermal limits of the original component require thermal analysis to confirm the substitute's adequacy. The higher reverse leakage current (100 nA versus 50 nA) may impact applications with stringent leakage specifications.

Frequently Asked Questions (FAQ)

Q: Can the CDZFHT2RA10B directly replace the MAZD10000L without PCB modifications?

A: Yes. Both components share identical surface mount packaging (2-SMD, flat lead) and footprint specifications, enabling direct substitution without PCB layout changes.

Q: What is the acceptable Zener voltage range for substitutes?

A: The MAZD10000L operates at 10 V ±6%, establishing an acceptable range of 9.4 V to 10.6 V. The CDZFHT2RA10B at 9.99 V falls within this range.

Q: Does the lower power rating of the CDZFHT2RA10B affect compatibility?

A: The CDZFHT2RA10B is rated at 100 mW compared to the original 120 mW. Applications operating near maximum power dissipation require thermal analysis to confirm the substitute's suitability. Lower-power applications are unaffected.

Q: Are there differences in reverse leakage current between these components?

A: Yes. The CDZFHT2RA10B exhibits 100 nA reverse leakage at 7 V, compared to 50 nA for the MAZD10000L. Applications with stringent leakage specifications should evaluate this parameter against circuit requirements.

Q: What certifications does the CDZFHT2RA10B carry?

A: The CDZFHT2RA10B is AEC-Q101 qualified for automotive applications and RoHS3 compliant. It is REACH unaffected and carries the same ECCN and HTSUS classifications as the original component.

Q: Why is the MAZD10000L classified as obsolete?

A: Panasonic has discontinued this component. The CDZFHT2RA10B provides functional equivalence for legacy system support and ongoing procurement requirements.

Q: Can the tighter tolerance of the CDZFHT2RA10B (±2.2%) improve circuit performance?

A: Tighter tolerance specifications can improve voltage regulation consistency and reduce circuit variability. Applications benefiting from improved tolerance performance may experience enhanced stability with the CDZFHT2RA10B.
