Key Parameters

Substitute Part Grouping Explanation

Substitution of the GDZ2V2B-G3-08 with the CMDZ2L2 TR PBFREE is permissible based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Zener voltage nominal rating: 2.2 V (identical)
• Package type: SOD-323 (identical mechanical footprint)
• Mounting configuration: Surface Mount (identical)
• RoHS3 compliance: Both parts meet ROHS3 Compliant status
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• REACH status: Both REACH Unaffected
• Operating temperature range: Both support -55°C to 150°C minimum (CMDZ2L2 extends to -65°C)

Allowable Parameter Variations:

• Voltage tolerance: GDZ2V2B-G3-08 at ±2% versus CMDZ2L2 at ±5% (substitute has wider tolerance)
• Power rating: GDZ2V2B-G3-08 at 200 mW versus CMDZ2L2 at 250 mW (substitute has higher power capability)
• Impedance: GDZ2V2B-G3-08 at 100 Ohms maximum versus CMDZ2L2 at 1000 Ohms maximum (substitute has higher impedance)
• Reverse leakage current: GDZ2V2B-G3-08 at 120 µA @ 700 mV versus CMDZ2L2 at 25 µA @ 1 V (substitute has lower leakage)

These variations remain within acceptable substitution criteria for Zener diode applications where the nominal voltage and package compatibility are primary selection drivers.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The GDZ2V2B-G3-08 remains the preferred component when the tighter voltage tolerance of ±2% is a circuit requirement. This part is Active status with established supply availability (867 Pcs in stock) and meets all regulatory compliance standards including ROHS3 and REACH unaffected designation.

Substitute Selection Criteria:

The CMDZ2L2 TR PBFREE is a valid substitute when circuit design permits the wider ±5% voltage tolerance and higher impedance characteristics. This part offers increased power dissipation capability (250 mW versus 200 mW) and lower reverse leakage current, with extended lower temperature operation (-65°C versus -55°C). The substitute maintains identical package footprint (SOD-323) and full compliance with ROHS3 and REACH requirements. Inventory availability for the substitute is higher (6960 Pcs in stock).

Both parts are Active status products suitable for production deployment. Selection between these components depends on tolerance and impedance specifications required by the specific circuit application.

Frequently Asked Questions (FAQ)

Q: Can the CMDZ2L2 TR PBFREE be used as a direct replacement for the GDZ2V2B-G3-08?

A: Yes, when circuit design specifications permit the wider voltage tolerance (±5% versus ±2%) and higher impedance (1000 Ohms versus 100 Ohms). Both components share identical 2.2 V nominal Zener voltage, SOD-323 package, and surface mount configuration. Verify that your application tolerates these parameter variations before substitution.

Q: Are there package compatibility concerns between these parts?

A: No. Both the GDZ2V2B-G3-08 and CMDZ2L2 TR PBFREE use the SC-76 / SOD-323 package designation, ensuring identical mechanical footprint and PCB land pattern compatibility.

Q: What is the impact of the impedance difference between these parts?

A: The GDZ2V2B-G3-08 has maximum impedance of 100 Ohms while the CMDZ2L2 TR PBFREE has maximum impedance of 1000 Ohms. Higher impedance affects voltage regulation characteristics and transient response. Confirm that your circuit design accommodates the substitute's impedance specification.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the GDZ2V2B-G3-08 and CMDZ2L2 TR PBFREE are ROHS3 Compliant, REACH Unaffected, and rated MSL 1 (Unlimited). Both are suitable for applications requiring these compliance standards.

Q: What is the significance of the reverse leakage current difference?

A: The GDZ2V2B-G3-08 specifies 120 µA @ 700 mV while the CMDZ2L2 TR PBFREE specifies 25 µA @ 1 V. The substitute exhibits lower leakage current, which may improve circuit performance in applications sensitive to standby current or leakage paths. Measurement conditions differ between specifications; direct comparison requires normalization to identical voltage conditions.

Q: Which part should be selected for new designs?

A: For new designs, select based on tolerance and impedance requirements. If ±2% voltage tolerance is mandatory, use the GDZ2V2B-G3-08. If ±5% tolerance is acceptable and lower leakage current is beneficial, the CMDZ2L2 TR PBFREE is suitable. Both parts are Active status and appropriate for production use.
