Key Parameters

Substitute Part Grouping Explanation

Substitute components for the DZ2W05600L are selected based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Package / Case: SOD-123F (physical and electrical compatibility)
• Power - Max: 1 W (thermal and current handling capability)
• Mounting Type: Surface Mount (assembly process compatibility)
• Current - Reverse Leakage @ Vr: 20 µA (leakage characteristics)

Secondary Matching Criteria:

• Voltage - Zener (Nom): Nominal values within the application tolerance band
• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling requirements)
• RoHS Compliance: Regulatory requirement for new designs

The three substitute parts identified (KDZVTR5.1B, KDZVTR5.6B, KDZVTFTR5.6B) all share the same SOD-123F package, 1 W power rating, and surface mount configuration. Zener voltage variations reflect different application requirements within the 5 V to 6 V regulation range.

Parameter Comparison

Engineering Selection Recommendations

KDZVTFTR5.6B (Rohm Semiconductor) is the primary substitute for the DZ2W05600L. This part maintains the closest nominal Zener voltage specification at 5.95 V and includes automotive-grade qualification (AEC-Q101) with operating temperature rating to 150°C. The KDZVTFTR5.6B is actively manufactured with high inventory availability (680,200 pcs) and carries ROHS3 compliance with REACH unaffected status.

KDZVTR5.6B (Rohm Semiconductor) serves as an alternative substitute with identical 5.95 V nominal voltage and 1 W power rating. This part is actively produced with moderate inventory (6,624 pcs) and meets ROHS3 compliance requirements.

KDZVTR5.1B (Rohm Semiconductor) is suitable for applications where a lower Zener voltage of 5.4 V is acceptable. This part is actively manufactured with adequate inventory (24,915 pcs) and meets ROHS3 compliance. Selection of this part requires confirmation that the 5.4 V regulation point is compatible with circuit design specifications.

All three substitute parts are manufactured by Rohm Semiconductor, share the SOD-123F package footprint, and maintain the 1 W power dissipation rating of the original component.

Frequently Asked Questions (FAQ)

Q: Can KDZVTR5.1B be used as a direct replacement for DZ2W05600L?

A: KDZVTR5.1B has a nominal Zener voltage of 5.4 V compared to the DZ2W05600L at 5.6 V. Direct substitution is possible only if the circuit design tolerates a 0.2 V lower regulation voltage. The difference represents approximately 3.6% deviation from the original specification.

Q: What is the difference between KDZVTR5.6B and KDZVTFTR5.6B?

A: Both parts have identical nominal Zener voltage (5.95 V) and power rating (1 W). KDZVTFTR5.6B includes automotive-grade qualification (AEC-Q101) and specified tolerance (±6.25%), while KDZVTR5.6B does not list tolerance specifications. KDZVTFTR5.6B has significantly higher inventory availability.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts (KDZVTR5.1B, KDZVTR5.6B, KDZVTFTR5.6B) use the SOD-123F package, identical to the DZ2W05600L. No PCB layout modifications are required for substitution.

Q: What is the impact of the voltage difference between DZ2W05600L (5.6 V) and KDZVTFTR5.6B (5.95 V)?

A: The KDZVTFTR5.6B operates at 5.95 V nominal, representing a 0.35 V increase (6.25% higher) compared to the original 5.6 V specification. Circuit compatibility depends on the voltage regulation tolerance band of the protected circuit. Applications with strict voltage requirements may require design review.

Q: Are moisture sensitivity levels equivalent across all parts?

A: Yes. The DZ2W05600L and all three substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.

Q: What is the RoHS compliance status of substitute parts?

A: All substitute parts meet ROHS3 compliance. The original DZ2W05600L meets RoHS Compliant status. ROHS3 represents an updated compliance standard and is acceptable for new designs and replacements.
