Substitute Part Grouping Explanation

Substitution of the DZ23C2V7-7 is based on strict equivalence of the following electrical and mechanical parameters:

Zener Voltage (Vz): 2.7 V nominal
Voltage Tolerance: ±5%
Maximum Power Dissipation: 300 mW
Maximum Impedance (Zzt): 83 Ohms
Operating Temperature Range: -65°C to 150°C
Configuration: 1 Pair Common Cathode
Package Type: SOT-23-3 surface mount
Moisture Sensitivity Level: 1 (Unlimited)

The substitute part DZ23C2V7-7-F meets all these parameters identically, ensuring direct functional and mechanical compatibility. The primary distinction between the main part and substitute is product status and compliance certification.

Engineering Selection Recommendations

DZ23C2V7-7-F is the direct substitute for DZ23C2V7-7. Selection of the substitute part is based on the following factors:

Product Status: The DZ23C2V7-7-F maintains Active product status, whereas the original part is Discontinued at DiGi Electronics. Active status ensures continued manufacturer support and supply chain availability.

Compliance Certifications: The DZ23C2V7-7-F is ROHS3 Compliant, compared to the non-compliant status of the original part. This compliance is relevant for applications subject to RoHS regulations and environmental standards.

Electrical and Mechanical Equivalence: All critical electrical parameters (Zener voltage, tolerance, power rating, impedance, operating temperature) and mechanical specifications (package type, configuration, mounting method) are identical between the two parts.

Inventory Availability: The substitute part has significantly higher inventory availability (9001 Pcs versus 1005 Pcs), supporting production continuity and reducing lead time risk.

For applications where RoHS compliance is not a requirement and existing stock of DZ23C2V7-7 is available, the original part remains functionally equivalent. For new designs and applications requiring compliance certification, DZ23C2V7-7-F is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are DZ23C2V7-7 and DZ23C2V7-7-F electrically identical?

A: Yes. Both parts have identical Zener voltage (2.7 V), voltage tolerance (±5%), maximum power dissipation (300 mW), impedance (83 Ohms maximum), and operating temperature range (-65°C to 150°C).

Q: Can DZ23C2V7-7-F be used as a direct replacement for DZ23C2V7-7 in existing designs?

A: Yes. The parts are mechanically and electrically equivalent. Both use SOT-23-3 surface mount packaging with identical pin configuration (1 Pair Common Cathode). No circuit modifications or PCB layout changes are required.

Q: What is the difference between SOT-23-3 and SOT-23F packaging?

A: Both designations refer to the same physical package format. SOT-23-3 is the standard package designation, while SOT-23F is the supplier device package designation used by Diodes Incorporated. The parts are physically and functionally identical.

Q: Why is DZ23C2V7-7 discontinued while DZ23C2V7-7-F remains active?

A: Product discontinuation decisions are made by manufacturers based on market demand, production efficiency, and compliance requirements. The active status of DZ23C2V7-7-F indicates it is the current production variant and recommended for new applications.

Q: Does the RoHS3 compliance of DZ23C2V7-7-F affect its electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical performance. The electrical specifications remain identical to the non-compliant variant.

Q: Are there any other substitute parts for DZ23C2V7-7?

A: Based on the provided data, DZ23C2V7-7-F is the only listed direct substitute. Both parts share the same base product number (DZ23) and are manufactured by Diodes Incorporated.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required before soldering.
