MAZ81600ML Equivalent & Substitute Parts

Part Overview

The MAZ81600ML is a Zener Diode rated at 16 V with 150 mW power dissipation, manufactured by Panasonic Electronic Components in the SMini2-F1 surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support, production continuity, and system maintenance. The 16 V Zener voltage rating and surface mount configuration define the primary functional requirements for substitution.

Substitute Part Grouping Explanation

Substitution of the MAZ81600ML is determined by the following critical parameters:

Primary Matching Criteria:

Zener voltage: 16 V nominal
Mounting type: Surface mount
Package compatibility: SC-90 or SOD-323F form factors

Secondary Compatibility Factors:

Power dissipation rating (minimum 150 mW required)
Reverse leakage current specifications
Forward voltage characteristics
Impedance ratings
Operating temperature range

Substitute parts are grouped into two categories based on package type and power rating. Parts with higher power ratings (300 mW, 310 mW, 550 mW) are direct functional upgrades suitable for applications where the original 150 mW rating is insufficient. Parts with equivalent or slightly higher power ratings maintain functional parity with the original component.

Engineering Selection Recommendations

Direct Package-Compatible Substitutes (SC-90, SOD-323F):

The BZX84J-B16,115, PZU16B2,115, and UDZVTE-1716B maintain physical and electrical compatibility with the MAZ81600ML footprint. These parts feature identical package geometry (SC-90, SOD-323F) and require no PCB layout modifications.

BZX84J-B16,115 offers the highest power rating (550 mW) with improved impedance characteristics (20 Ohms) and tighter tolerance (±2%). This part carries AEC-Q101 automotive qualification and is suitable for applications requiring enhanced thermal performance.

PZU16B2,115 provides 310 mW power dissipation with ±2% tolerance and AEC-Q100 automotive qualification. This part balances performance improvement over the original 150 mW rating while maintaining compact form factor.

UDZVTE-1716B delivers 200 mW power dissipation with impedance matching the original specification (50 Ohms). This part is suitable for direct replacement in applications where power rating is not a limiting factor.

Alternative Package Substitutes (SC-79, SOD-523):

BZX585-B16,115 and BZX585-C16,115 utilize the SOD-523 package, which differs from the original SMini2-F1 footprint. These parts require PCB layout verification and potential redesign. Both offer 300 mW power dissipation with improved impedance (40 Ohms). BZX585-B16,115 provides ±2% tolerance with AEC-Q101 qualification. BZX585-C16,115 offers ±5% tolerance without automotive qualification.

Product Status Consideration:

All substitute parts carry active product status, ensuring long-term availability and supply chain continuity. The original MAZ81600ML obsolete status necessitates transition to one of these active alternatives.

Frequently Asked Questions (FAQ)

Q: Can BZX585-B16,115 or BZX585-C16,115 be used as direct replacements for MAZ81600ML?

A: These parts are functionally equivalent in electrical performance but require PCB layout verification. The SOD-523 package differs from the original SMini2-F1 footprint. Physical board modifications may be necessary. Confirm pad spacing and component placement compatibility before implementation.

Q: What is the primary advantage of BZX84J-B16,115 over the original MAZ81600ML?

A: BZX84J-B16,115 provides 550 mW power dissipation compared to the original 150 mW rating, representing a 3.67× increase in thermal capacity.
