Key Parameters

Substitute Part Grouping Explanation

Substitute selection for CZRW4698-G is determined strictly by matching key electrical, mechanical, and package parameters. The essential parameters for equivalency include:

• Zener Voltage (Vz): 11 V
• Tolerance: ±5%
• Power - Max (dissipation): ≥350 mW
• Reverse Leakage Current @ Vr: ≤50 nA @ 8.4 V
• Forward Voltage (Vf) (Max) @ If: ≤900 mV @ 10 mA
• Operating Temperature: -65°C or lower to 150°C or higher
• Mounting Type: Surface Mount
• Package / Case: SOD-123

Only substitute parts strictly matching or exceeding these criteria are included.

Parameter Comparison

Engineering Selection Recommendations

The main part, CZRW4698-G, is obsolete. MMSZ4698-HF is active and RoHS3 compliant. Both CZRW4698-G and MMSZ4698-HF are classified as EAR99. The substitute MMSZ4698-HF has an equivalent or higher power rating and identical electrical and mechanical parameters according to the provided input.

Frequently Asked Questions (FAQ)

Q: What criteria are used to determine a substitute for CZRW4698-G?
A: Substitutes are determined based on Zener voltage, tolerance, power dissipation, reverse leakage current, forward voltage, operating temperature range, mounting type, and package.

Q: Is the SOD-123 package consistent between the original and substitute parts?
A: Yes, both CZRW4698-G and MMSZ4698-HF are supplied in the SOD-123 package.

Q: Are there any differences in electrical ratings between CZRW4698-G and MMSZ4698-HF?
A: Electrical parameters such as Zener voltage, tolerance, reverse leakage current, and forward voltage are identical. MMSZ4698-HF has a higher power rating.

Q: How does product status affect substitute selection?
A: Since CZRW4698-G is obsolete, only active production-status parts with matching parameters are considered suitable substitutes.

Q: Are compliance and certifications matched?
A: Both parts are classified as EAR99. MMSZ4698-HF is RoHS3 compliant as specified.
