Substitute Part Grouping Explanation

Substitute parts for the BZX584B16 RKG are qualified based on the following substitution criteria:

Primary Matching Parameters:

• Zener voltage rating: 16 V nominal (or 15 V for near-equivalent applications)
• Power dissipation: 150 mW minimum (higher ratings acceptable)
• Voltage tolerance: ±2% to ±5.6%
• Package compatibility: SOD-523 or SC-79 surface mount packages
• Impedance: 40 to 50 Ohms maximum
• Reverse leakage current: 50 to 100 nA range
• Operating temperature: Maximum 150°C junction temperature
• Compliance: ROHS3 compliant, REACH unaffected, MSL 1

Substitution Logic: Parts are grouped into two categories: direct equivalents (matching 16 V rating with identical or superior power ratings) and near-equivalents (15 V rating with compatible electrical characteristics). All substitute parts maintain surface mount assembly compatibility and regulatory compliance with the original component.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - EDZVT2R16B (Rohm Semiconductor): The EDZVT2R16B is a direct functional equivalent with matching 16 V Zener voltage, ±2% tolerance, and 150 mW power rating. This part maintains identical electrical specifications and package compatibility. The impedance specification of 50 Ohms is within acceptable tolerance variance. All regulatory certifications (ROHS3, REACH unaffected, MSL 1) align with the original component. This substitute is suitable for one-to-one replacement in existing designs.

Near-Equivalent - EDZVT2R15B (Rohm Semiconductor): The EDZVT2R15B operates at 15 V nominal Zener voltage with ±2% tolerance and 150 mW power rating. This 1 V lower rating is applicable in circuits where the voltage regulation point can accommodate a 6% reduction from the original 16 V specification. Impedance and reverse leakage characteristics are comparable. All compliance certifications match the original part. This substitute is suitable for applications with flexible voltage regulation requirements.

Higher Power Equivalent - MM5Z16VT1G (onsemi): The MM5Z16VT1G provides 16 V Zener voltage with 500 mW maximum power dissipation, representing a 3.3× power capability increase over the original 150 mW rating. The ±5.6% tolerance is wider than the original ±2% specification. Impedance and reverse leakage characteristics are equivalent or superior. All regulatory certifications are maintained. This substitute is suitable for applications requiring enhanced thermal performance or higher current handling capacity within the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can EDZVT2R16B replace BZX584B16 RKG in all applications? A: Yes. The EDZVT2R16B is a direct equivalent with matching 16 V Zener voltage, ±2% tolerance, 150 mW power rating, and SOD-523 package compatibility. All electrical parameters and regulatory certifications are equivalent.

Q: What is the primary difference between EDZVT2R15B and the original BZX584B16 RKG? A: The EDZVT2R15B operates at 15 V nominal Zener voltage instead of 16 V. This 1 V difference represents approximately 6% lower voltage regulation. The part is suitable for applications where this voltage variance is acceptable within circuit design tolerances.

Q: Why does MM5Z16VT1G have a higher power rating? A: The MM5Z16VT1G is rated for 500 mW maximum power dissipation compared to 150 mW in the original part. This higher rating allows the component to dissipate greater thermal energy while maintaining the same 16 V Zener voltage and SOD-523 package dimensions. The wider ±5.6% tolerance should be evaluated against circuit requirements.

Q: Are all substitute parts available in the same package? A: All substitute parts use the SOD-523 package family (SC-79 case designation). Supplier device packages vary: the original uses SOD-523F, while EDZVT2R16B and EDZVT2R15B use EMD2, and MM5Z16VT1G uses SOD-523. These are mechanically and electrically compatible within the SOD-523 standard.

Q: Do all parts meet the same environmental and compliance standards? A: Yes. All parts listed are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Operating temperature maximum is 150°C for all parts. Regulatory compliance is equivalent across all options.

Q: Which substitute should be selected for maximum design flexibility? A: Selection depends on circuit requirements. For direct replacement with identical specifications, use EDZVT2R16B. For applications tolerating lower voltage regulation, use EDZVT2R15B. For circuits requiring higher power dissipation capability, use MM5Z16VT1G. All three maintain full regulatory compliance and package compatibility.
