MAZ80470ML Equivalent & Substitute Parts

Part Overview

The MAZ80470ML is a Zener diode manufactured by Panasonic Electronic Components, rated at 4.7 V nominal with 150 mW maximum power dissipation in a surface mount SMini2-F1 package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The 4.7 V Zener voltage with ±6% tolerance and surface mount configuration defines the functional requirements for identifying compatible alternatives.

Substitute Part Grouping Explanation

Substitution of the MAZ80470ML is determined by the following critical parameters:

Primary Matching Criteria:

Zener voltage nominal value of 4.7 V (tolerance range 4.418 V to 4.982 V at ±6%)
Surface mount configuration
Maximum power dissipation equal to or greater than 150 mW
Impedance (Zzt) at or below 80 Ohms maximum
Reverse leakage current specifications compatible with application requirements

Secondary Compatibility Factors:

Package compatibility (SOD-323F, SOD-523, TUMD2, UMD2 packages acceptable for surface mount applications)
Forward voltage characteristics within acceptable operating ranges
Operating temperature range coverage

Substitute parts are grouped into three categories based on power rating and package type: higher power variants (300–550 mW), equivalent power variants (200 mW), and specialized automotive-grade options. All substitute parts maintain the 4.7 V nominal Zener voltage specification and surface mount mounting type.

Engineering Selection Recommendations

Direct Package Compatibility (SOD-323F): BZX84J-C4V7,115 and UDZSTE-174.7B maintain the same SOD-323F package as the MAZ80470ML. BZX84J-C4V7,115 provides increased power handling (550 mW versus 150 mW) with tighter tolerance (±5% versus ±6%) and active product status with AEC-Q101 automotive qualification. UDZSTE-174.7B offers equivalent package compatibility with 200 mW power rating and ±2% tolerance, suitable for applications requiring lower power dissipation.

Higher Power Capability: BZX585-B4V7,115 and BZX585-B4V7,135 deliver 300 mW power dissipation in SOD-523 package with superior ±2% tolerance and AEC-Q100 automotive qualification. These parts accommodate applications requiring increased thermal headroom beyond the original 150 mW specification.

Automotive-Grade Options: BZT52H-C4V7,115 combines automotive qualification (AEC-Q101) with 375 mW power rating in SOD-123F package. UDZVFHTE-174.7B and YFZVFHTR4.7B provide automotive-grade alternatives with AEC-Q101 qualification for temperature-critical applications.

All substitute parts are active products with RoHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can BZX84J-C4V7,115 replace MAZ80470ML in existing designs? A: Yes. BZX84J-C4V7,115 maintains identical SOD-323F package, 4.7 V nominal Zener voltage, and 80 Ohm maximum impedance. The higher 550 mW power rating and ±5% tolerance are compatible with applications designed for the 150 mW MAZ80470ML. Verify circuit requirements do not depend on the original ±6% tolerance specification.

Q: What is the difference between BZX585-B4V7,115 and BZX585-B4V7,135? A: Both parts are electrically identical with 4.7 V nominal voltage, 300 mW power rating, ±2% tolerance, and SOD-523 package. The difference is packaging format: BZX585-B4V7,115 is supplied in Tape & Reel format, while BZX585-B4V7,135 is also supplied in Tape & Reel. Inventory levels differ (7709 Pcs versus 10917 Pcs).

Q: Are Rohm TFZGTR4.7B and TFZVTR4.7B interchangeable? A: Both parts share identical electrical specifications: 4.7 V nominal voltage, 500 mW power rating, 25 Ohm impedance, and 2-SMD flat lead package. TFZVTR4.7B uses TUMD2M package variant while TFZGTR4.7B uses TUMD2. Verify PCB footprint compatibility before substitution.

Q: Can UDZVFHTE-174.7B substitute for MAZ80470ML despite 4.65 V nominal voltage? A: UDZVFHTE-174.7B has 4.65 V nominal voltage with ±2.15% tolerance, resulting in operating range of 4.545 V to 4.755 V. This overlaps the MAZ80470ML range (4.418 V to 4.982 V) but operates at the lower end. Substitution is valid only if circuit design tolerates 4.65 V operation. This part includes AEC-Q101 automotive qualification and 200 mW power rating.

Q: Which substitute offers the best tolerance specification? A: BZX585-B4V7,115 and BZX585-B4V7,135 provide ±2% tolerance, the tightest specification among all substitutes. UDZSTE-174.7B and UDZVFHTE-174.7B also offer ±2% and ±2.15% respectively. These tighter tolerances reduce voltage variation across production batches compared to the original ±6% specification.

Q: What package considerations apply when substituting from SOD-323F to SOD-523? A: SOD-523 is a smaller package than SOD-323F. BZX585-B4V7,115 and BZX585-B4V7,135 in SOD-523 require PCB footprint redesign. Verify available board space and manufacturing capability before selecting SOD-523 variants. SOD-323F alternatives (BZX84J-C4V7,115, UDZSTE-174.7B) eliminate footprint redesign requirements.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts listed carry RoHS3 compliance status. The original MAZ80470ML does not specify RoHS status in provided data. All substitutes are REACH unaffected, ensuring regulatory compliance for new designs.

Q: Which substitute provides the lowest impedance? A: TFZGTR4.7B, TFZVTR4.7B, and YFZVFHTR4.7B all specify 25 Ohm maximum impedance, compared to 80 Ohm for the MAZ80470ML. Lower impedance reduces voltage variation under load changes. These parts are supplied by Rohm Semiconductor in TUMD2 and TUMD2M packages.
