Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDBZ0130L-HF is determined by strict equivalence of the following electrical and mechanical parameters:

Primary Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 30V
• Current - Average Rectified (Io): 100mA
• Voltage - Forward (Vf) (Max) @ If: 370mV @ 10mA
• Package / Case: 0201 (0603 Metric)
• Mounting Type: Surface Mount
• Technology: Schottky

Substitute Classification:

Direct Equivalent (Same Manufacturer, Active Status): CDBZC0130L-HF maintains identical electrical specifications and package form factor. This part differs only in packaging format (Tape & Reel vs. bulk) and includes automotive-grade qualification (AEC-Q101) with extended operating temperature range (-40°C ~ 125°C).

Functional Equivalent (Alternative Manufacturer, Enhanced Performance): SDM02U30LP3-7B by Diodes Incorporated meets all primary electrical specifications with improved reverse leakage current (4µA @ 30V vs. 7µA @ 10V) and extended maximum junction temperature (150°C vs. 125°C). Package designation differs (X3-DFN0603-2 vs. 0201/0603 Metric) but maintains mechanical compatibility.

Functional Substitute (Alternative Manufacturer, Different Package): DSR01S30SL,L3F by Toshiba Semiconductor meets voltage and current ratings but uses a 2-SMD No Lead package (SL2) instead of 0201 form factor. Forward voltage specification differs (620mV @ 100mA vs. 370mV @ 10mA), and reverse leakage is significantly lower (700nA @ 30V).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): CDBZC0130L-HF is the primary equivalent for CDBZ0130L-HF. Both parts are manufactured by Comchip Technology with identical electrical specifications and 0201 (0603 Metric) package compatibility. CDBZC0130L-HF offers active product status with higher inventory availability (10300 units) and includes AEC-Q101 automotive qualification with extended operating temperature range (-40°C ~ 125°C). This part is suitable for applications requiring direct form-factor compatibility and same-manufacturer continuity.

For Enhanced Performance Requirements: SDM02U30LP3-7B by Diodes Incorporated provides functional equivalence with measurable performance improvements. The reverse leakage current is reduced to 4µA @ 30V (compared to 7µA @ 10V in the original), and maximum junction temperature extends to 150°C. The X3-DFN0603-2 package maintains mechanical compatibility with 0201 (0603 Metric) footprints. Significantly higher inventory (165300 units) supports supply chain continuity. This selection is appropriate for applications with extended temperature requirements or reduced leakage specifications.

For Alternative Package Configurations: DSR01S30SL,L3F by Toshiba Semiconductor meets core voltage and current specifications but uses a 2-SMD No Lead (SL2) package. This part exhibits superior reverse leakage performance (700nA @ 30V) and includes capacitance specification (8.2pF @ 0V, 1MHz). Selection of this part requires PCB layout modification to accommodate the SL2 package form factor and is suitable only when package footprint constraints permit alternative geometries.

Frequently Asked Questions (FAQ)

Q: Can CDBZC0130L-HF directly replace CDBZ0130L-HF without circuit modification?

A: Yes. CDBZC0130L-HF is a direct equivalent with identical electrical specifications (30V, 100mA, 370mV forward voltage) and the same 0201 (0603 Metric) surface mount package. The primary difference is packaging format (Tape & Reel vs. bulk) and active product status. No circuit or PCB layout changes are required.

Q: What are the advantages of SDM02U30LP3-7B over the original CDBZ0130L-HF?

A: SDM02U30LP3-7B provides three measurable improvements: (1) reduced reverse leakage current of 4µA @ 30V compared to 7µA @ 10V, (2) extended maximum junction temperature of 150°C versus 125°C, and (3) significantly higher inventory availability (165300 units). The part maintains electrical equivalence for voltage and current ratings and is compatible with 0201 (0603 Metric) PCB footprints.

Q: Is DSR01S30SL,L3F compatible with existing PCB layouts designed for CDBZ0130L-HF?

A: No. DSR01S30SL,L3F uses a 2-SMD No Lead (SL2) package, which differs from the 0201 (0603 Metric) form factor of the original part. PCB layout modification is required to accommodate the alternative package geometry. This substitution is suitable only when design constraints permit package footprint changes.

Q: What is the significance of the AEC-Q101 qualification on CDBZC0130L-HF?

A: AEC-Q101 is an automotive-grade qualification standard. CDBZC0130L-HF meets this qualification with an extended operating temperature range of -40°C ~ 125°C, compared to the original part's maximum of 125°C. This qualification is relevant for automotive and industrial applications requiring enhanced reliability and temperature performance specifications.

Q: How do the forward voltage specifications differ among these parts?

A: CDBZ0130L-HF, CDBZC0130L-HF, and SDM02U30LP3-7B all specify 370mV @ 10mA forward voltage, ensuring functional equivalence in low-current applications. DSR01S30SL,L3F specifies 620mV @ 100mA, which is measured at a different current level and reflects the part's performance at higher current conditions. This difference does not prevent substitution but indicates different measurement conditions.

Q: What is the Moisture Sensitivity Level (MSL) rating, and why is it important?

A: All four parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture exposure precautions. This specification ensures that storage, handling, and assembly processes do not require special moisture control measures, simplifying supply chain management and manufacturing procedures.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CDBZ0130L-HF, CDBZC0130L-HF, SDM02U30LP3-7B, and DSR01S30SL,L3F are all ROHS3 compliant, meeting environmental and regulatory requirements for lead-free and restricted substance compliance.
