Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2J110M0L is determined by the following critical parameters:

Primary Matching Criteria:

• Zener voltage: 11 V nominal
• Package compatibility: SC-90 or SOD-323F surface mount packages
• Mounting type: Surface mount
• Moisture sensitivity: MSL 1 (Unlimited)

Secondary Compatibility Factors:

• Power rating: 200 mW or higher
• Impedance: 30 Ohms or lower
• Reverse leakage current: 50 nA or lower @ 8 V
• Voltage tolerance: ±2.5% or tighter
• RoHS compliance status

Substitute parts are grouped into two categories based on electrical performance alignment:

Category A - Direct Electrical Equivalents: Parts maintaining identical power rating (200 mW), impedance (30 Ohms), and package specifications with equivalent or superior tolerance specifications.

Category B - Enhanced Performance Alternatives: Parts with increased power rating (300 mW) or improved electrical characteristics while maintaining package and voltage compatibility.

Engineering Selection Recommendations

UDZSTE-1711B (Rohm Semiconductor) is the primary substitute for the DZ2J110M0L. This part maintains identical electrical specifications including 11 V zener voltage, 200 mW power rating, and 30 Ohms impedance. The UDZSTE-1711B offers superior voltage tolerance (±2% versus ±2.5%) and is packaged in the compatible SC-90/SOD-323F format. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Operating temperature range of -55°C to 150°C provides adequate thermal performance for standard applications.

UDZVFHTE-1711B (Rohm Semiconductor) serves as an alternative for applications requiring automotive-grade qualification. This variant maintains identical electrical and package specifications while providing AEC-Q101 qualification and automotive-grade certification. The maximum junction temperature rating of 150°C and ±2.09% tolerance make this suitable for automotive and high-reliability applications. Product status is active with ROHS3 compliance.

UDZVTE-1711B (Rohm Semiconductor) provides a functionally equivalent option with identical power rating, impedance, and package specifications. Operating temperature range of -55°C to 150°C and active product status support standard industrial applications. This part is available in higher inventory quantities and offers cost-effective substitution.

MM3Z11VT1G (onsemi) is suitable for applications where enhanced power dissipation capability is beneficial. This part provides 300 mW maximum power rating with improved impedance specification (20 Ohms versus 30 Ohms) and superior forward voltage characteristics (900 mV versus 1 V @ 10 mA). The wider operating temperature range (-65°C to 150°C) accommodates extended environmental conditions. Package designation is SC-76/SOD-323, which is mechanically compatible with SOD-323F footprints. The ±5% tolerance is broader than the original specification but remains acceptable for voltage regulation applications. Product status is active with extensive inventory availability.

All substitute parts maintain RoHS compliance, MSL 1 rating, and surface mount configuration compatibility with the original DZ2J110M0L design.

Frequently Asked Questions (FAQ)

Q: Can the MM3Z11VT1G replace the DZ2J110M0L in all applications?

A: The MM3Z11VT1G is electrically compatible as a substitute. The primary differences are increased power rating (300 mW versus 200 mW), improved impedance (20 Ohms versus 30 Ohms), and broader voltage tolerance (±5% versus ±2.5%). Applications requiring the tighter tolerance specification of the original part should use UDZSTE-1711B, UDZVFHTE-1711B, or UDZVTE-1711B instead. The MM3Z11VT1G is suitable for applications where the enhanced power capability and lower impedance provide design margin.

Q: What is the difference between the Rohm Semiconductor substitute options?

A: UDZSTE-1711B, UDZVFHTE-1711B, and UDZVTE-1711B are all Rohm Semiconductor products with identical electrical specifications (11 V, 200 mW, 30 Ohms impedance) and package compatibility (SC-90/SOD-323F). UDZVFHTE-1711B includes automotive-grade qualification and AEC-Q101 certification, making it suitable for automotive applications. UDZSTE-1711B and UDZVTE-1711B are standard industrial-grade variants. Selection depends on application requirements and qualification needs.

Q: Are the package designations SC-90, SOD-323F, and SOD-323 interchangeable?

A: SC-90 and SOD-323F are equivalent package designations for the same physical form factor used by Panasonic and Rohm Semiconductor. SOD-323 (used by onsemi MM3Z11VT1G) is mechanically compatible with SOD-323F footprints and can be used in the same PCB layout. All three designations refer to surface mount packages suitable for automated assembly.

Q: Why does the DZ2J110M0L show 50 nA reverse leakage while substitutes show 100 nA?

A: The reverse leakage current specification of 100 nA for substitute parts is measured at the same conditions (8 V) as the original 50 nA specification. The higher leakage in substitutes represents a relaxed specification but remains within acceptable limits for voltage regulation and protection applications. Applications with stringent leakage requirements should confirm compatibility with circuit design parameters.

Q: What is the significance of the ±2.5% tolerance specification?

A: The ±2.5% tolerance indicates the maximum deviation of the zener voltage from the nominal 11 V specification across the operating range. UDZSTE-1711B and UDZVFHTE-1711B offer tighter tolerances (±2% and ±2.09% respectively), providing more precise voltage regulation. MM3Z11VT1G has a broader ±5% tolerance. Selection depends on circuit requirements for voltage accuracy.

Q: Can I use the MM3Z11VT1G in a design originally specified for 200 mW power dissipation?

A: Yes. The MM3Z11VT1G is rated for 300 mW maximum power dissipation, which exceeds the 200 mW requirement of the original DZ2J110M0L. This provides additional thermal margin and reliability. The part is electrically and mechanically compatible with the original design footprint.

Q: What does RoHS compliance and ROHS3 compliance mean for substitution?

A: Both the original DZ2J110M0L (RoHS Compliant) and all substitute parts (ROHS3 Compliant) meet lead-free and hazardous substance restrictions. ROHS3 represents the current regulatory standard. All parts are suitable for applications requiring RoHS compliance.

Q: Are all substitute parts available in the same packaging formats?

A: Rohm Semiconductor parts (UDZSTE-1711B, UDZVFHTE-1711B, UDZVTE-1711B) are available in Cut Tape (CT) and Digi-Reel formats. The onsemi MM3Z11VT1G is available in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements and order quantities.
