Substitute Part Grouping Explanation

Substitution of the BZX585-C62,115 is determined by the following critical electrical parameters: nominal Zener voltage of 62 V, operating temperature range of -65°C to 150°C, surface mount technology, and automotive-grade qualification. The substitute parts MM3Z62VB and MM3Z62VC maintain the 62 V nominal Zener voltage and identical operating temperature range. Both substitutes are surface mount Zener diodes with AEC-Q100 compliance or equivalent automotive qualification.

The primary distinction between the main part and substitutes is power dissipation rating and package form factor. The BZX585-C62,115 provides 300 mW maximum power in SOD-523 package, while MM3Z62VB and MM3Z62VC provide 200 mW maximum power in SOD-323F package. Impedance values remain within acceptable engineering tolerance (215 Ohms main part versus 202 Ohms substitutes). Reverse leakage current and forward voltage characteristics are comparable across all three parts.

Substitution is valid when circuit design requirements do not exceed 200 mW power dissipation and when SOD-323F package dimensions are compatible with the application layout.

Parameter Comparison

Engineering Selection Recommendations

Selection between BZX585-C62,115 and its substitutes is based on circuit power dissipation requirements and package compatibility.

BZX585-C62,115 is selected when:

• Circuit design requires maximum power dissipation of 300 mW
• SOD-523 package footprint is specified in the application layout
• Nexperia component sourcing is required

MM3Z62VC is selected when:

• Circuit design operates within 200 mW maximum power dissipation
• SOD-323F package dimensions are compatible with application
• ±5% tolerance matches the original specification
• Fairchild Semiconductor sourcing is acceptable

MM3Z62VB is selected when:

• Circuit design operates within 200 mW maximum power dissipation
• SOD-323F package dimensions are compatible with application
• ±2% tolerance provides improved voltage accuracy over the original ±5% specification
• Fairchild Semiconductor sourcing is acceptable

All three parts maintain identical operating temperature range (-65°C to 150°C), identical nominal Zener voltage (62 V), and equivalent electrical performance within their respective power ratings. All parts are Active product status with automotive-grade qualification.

Frequently Asked Questions (FAQ)

Q: Can MM3Z62VB or MM3Z62VC be used as direct replacements for BZX585-C62,115?

A: Direct replacement is valid only when circuit power dissipation does not exceed 200 mW. The substitute parts are rated at 200 mW maximum versus 300 mW for the original part. If the application requires the full 300 mW capability, substitution is not appropriate. Additionally, the SOD-323F package has different physical dimensions than SOD-523, requiring PCB layout verification.

Q: What is the difference between MM3Z62VB and MM3Z62VC?

A: Both parts are identical in electrical performance and package type (SOD-323F). The primary difference is tolerance specification: MM3Z62VB provides ±2% tolerance while MM3Z62VC provides ±5% tolerance. MM3Z62VB offers tighter voltage accuracy if the application requires it.

Q: Are all three parts automotive-qualified?

A: The BZX585-C62,115 carries explicit AEC-Q100 automotive qualification. The MM3Z62VB and MM3Z62VC are manufactured by Fairchild Semiconductor and are surface mount Zener diodes with automotive-grade classification. All three parts operate across the identical temperature range (-65°C to 150°C) required for automotive applications.

Q: What is the significance of the package difference between SOD-523 and SOD-323F?

A: SOD-523 and SOD-323F are different surface mount package outlines with different physical dimensions and land patterns. PCB layout compatibility must be verified before substitution. The SOD-323F package is smaller than SOD-523. Substitution requires confirmation that the application PCB can accommodate the SOD-323F footprint.

Q: Can I use these parts interchangeably in high-power applications?

A: No. The BZX585-C62,115 is rated at 300 mW maximum power dissipation. The MM3Z62VB and MM3Z62VC are rated at 200 mW maximum. In applications requiring sustained power dissipation above 200 mW, only the BZX585-C62,115 is appropriate. Exceeding the power rating of the substitute parts will result in component failure.

Q: Are there any compliance differences between these parts?

A: The BZX585-C62,115 is explicitly ROHS3 compliant. Both substitute parts carry EAR99 ECCN classification and 8541.10.0050 HTSUS code, matching the original part. RoHS compliance status for the substitute parts is not specified in the available data.
