Substitute Part Grouping Explanation

Substitution of the MMFZ2V7T1G is determined by equivalence across the following critical parameters:

Primary Matching Criteria:

• Zener voltage nominal rating: 2.7 V
• Maximum power dissipation: 500 mW
• Package type: SOD-123 surface mount
• Mounting configuration: Surface mount

Secondary Compatibility Factors:

• Moisture sensitivity level: 1 (Unlimited)
• Regulatory compliance: REACH Unaffected, ECCN EAR99
• Supplier device package: SOD-123

The MMSZ2V7T1G meets all primary and secondary matching criteria and is classified as a direct substitute. This part maintains identical electrical specifications for zener voltage and power rating while offering active product status and enhanced documentation through tolerance specification (±5%).

Parameter Comparison

Engineering Selection Recommendations

MMSZ2V7T1G as Primary Substitute:

The MMSZ2V7T1G is the direct equivalent for the obsolete MMFZ2V7T1G. Both components are manufactured by onsemi and share identical electrical specifications: 2.7 V zener voltage and 500 mW maximum power dissipation. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The MMSZ2V7T1G provides additional technical documentation through explicit tolerance specification (±5%) and expanded operating temperature range (-55°C to 150°C), which may benefit design validation and thermal analysis. Both parts maintain equivalent regulatory compliance with REACH Unaffected status and EAR99 export classification.

Packaging compatibility is confirmed: both components utilize SOD-123 surface mount packaging with identical moisture sensitivity level (MSL 1, Unlimited). PCB layout, thermal management, and assembly processes require no modification when transitioning from MMFZ2V7T1G to MMSZ2V7T1G.
