Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical parameter compatibility:

Category 1: Direct Voltage Equivalents (62 V Nominal)

Parts in this category maintain the 62 V nominal Zener voltage specification, ensuring direct functional equivalence in voltage regulation and protection applications. These parts are suitable for one-to-one replacement without circuit redesign.

• MM3Z62VC (Fairchild Semiconductor): 62 V, 200 mW, ±5% tolerance, SOD-323F package
• MM3Z62VB (Fairchild Semiconductor): 62 V, 200 mW, ±2% tolerance, SOD-323F package
• UDZLVTE-1762 (Rohm Semiconductor): 62 V, 200 mW, SOD-323FL package

Category 2: Alternative Voltage Ratings (68 V Nominal)

Parts in this category operate at 68 V nominal Zener voltage. These are classified as similar substitutes for applications where the higher voltage rating is acceptable within circuit design parameters.

• MM3Z68VC (Fairchild Semiconductor): 68 V, 200 mW, ±5% tolerance, SOD-323F package
• MM3Z68VB (onsemi): 68 V, 200 mW, ±2% tolerance, SOD-323F package
• UDZLVTE-1768 (Rohm Semiconductor): 68 V, 200 mW, SOD-323F package

Key Parameters Determining Substitution:

• Nominal Zener voltage (62 V or 68 V)
• Maximum power dissipation (200 mW)
• Package type (SOD-323F or SOD-323FL)
• Mounting type (Surface Mount)
• Operating temperature range (-65°C to 150°C minimum)

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (62 V Category):

MM3Z62VC is the primary direct equivalent to BZT52C62S RRG. Both devices share identical electrical specifications: 62 V nominal voltage, ±5% tolerance, 200 mW power rating, and SOD-323F packaging. This part is Active product status and suitable for one-to-one substitution.

MM3Z62VB offers improved tolerance (±2% versus ±5%), maintaining all other electrical parameters and package compatibility. This part is Active product status and may be selected when tighter voltage tolerance is required.

UDZLVTE-1762 maintains 62 V nominal voltage and 200 mW power rating in SOD-323FL packaging. This part is Active product status and RoHS3 compliant. Note that reverse leakage current specification differs from the main part.

Alternative Voltage Rating (68 V Category):

MM3Z68VC and MM3Z68VB are 68 V nominal Zener diodes with 200 mW power dissipation. Both are Active product status and RoHS3 compliant. These parts are suitable for applications where 68 V regulation voltage is acceptable.

UDZLVTE-1768 is a 68 V nominal Zener diode with 200 mW power dissipation, Active product status, and RoHS3 compliant. Operating temperature range is -40°C to 150°C.

All substitute parts listed are RoHS3 compliant and carry Active product status, supporting long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can MM3Z62VC be used as a direct replacement for BZT52C62S RRG?

A: Yes. MM3Z62VC is a direct equivalent with identical nominal voltage (62 V), power rating (200 mW), tolerance (±5%), and SOD-323F packaging. Both devices operate across -65°C to 150°C and are RoHS3 compliant.

Q: What is the difference between MM3Z62VB and MM3Z62VC?

A: Both parts are 62 V, 200 mW Zener diodes in SOD-323F packaging. The primary difference is tolerance: MM3Z62VB offers ±2% tolerance compared to ±5% for MM3Z62VC. Impedance values are identical at 202 Ohms.

Q: Can 68 V Zener diodes (MM3Z68VC, MM3Z68VB, UDZLVTE-1768) replace the 62 V BZT52C62S RRG?

A: These are classified as similar substitutes, not direct equivalents. The 68 V rating is 9.7% higher than the 62 V specification. Substitution is permissible only if circuit design parameters accommodate the higher voltage regulation point.

Q: What is the difference between SOD-323F and SOD-323FL packaging?

A: Both are surface mount packages in the SC-90 form factor. SOD-323FL is a variant designation used by Rohm Semiconductor. Physical dimensions and mounting characteristics are compatible for standard PCB assembly processes.

Q: Are all substitute parts RoHS3 compliant?

A: MM3Z62VC, MM3Z62VB, MM3Z68VC, MM3Z68VB, UDZLVTE-1762, and UDZLVTE-1768 are all RoHS3 compliant. The main part BZT52C62S RRG is also RoHS3 compliant.

Q: What is the operating temperature range for UDZLVTE parts?

A: UDZLVTE-1762 and UDZLVTE-1768 operate from -40°C to 150°C, compared to -65°C to 150°C for the main part and other substitutes. This represents a narrower low-temperature range.

Q: How do reverse leakage current specifications compare?

A: BZT52C62S RRG and direct 62 V equivalents (MM3Z62VC, MM3Z62VB) specify 45 nA @ 43.4 V. UDZLVTE-1762 specifies 200 µA @ 47 V, which is significantly higher. For 68 V parts, leakage is specified at different voltage points: 45 nA @ 47.6 V for MM3Z68 series and 200 nA @ 52 V for UDZLVTE-1768.

Q: Which substitute offers the best tolerance specification?

A: MM3Z62VB and MM3Z68VB both offer ±2% tolerance, compared to ±5% for the main part and MM3Z62VC/MM3Z68VC. Tighter tolerance reduces voltage regulation variation in circuit applications.

Q: Are there inventory considerations for these substitutes?

A: Inventory levels vary by part and supplier. MM3Z62VC and MM3Z68VC show high availability (34,850 and 32,756 units respectively). UDZLVTE parts show lower availability (1,155 and 4,937 units respectively). Procurement planning should account for these differences.
