Key Parameters

Substitute Part Grouping Explanation

Substitution of CDBUR0230 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 500 mV @ 200 mA
• Current - Reverse Leakage @ Vr: 30 µA (at specified voltage)
• Operating Temperature - Junction (Max): 125°C

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: 2-SMD, No Lead
• Supplier Device Package: 0603/SOD-523F or 0603C/SOD-523F

Compliance Equivalence Criteria:

• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts maintain these parameters within the allowed specifications for direct component substitution in the same circuit application.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts—CDBU0230, CDBU0230-HF, CDBU0230L-HF, and CDBUR0230L—are active products manufactured by Comchip Technology with full ROHS3 compliance and REACH unaffected status. Selection among these equivalents is based on the following factors:

Package Variant Consideration: CDBUR0230 and CDBUR0230L use the 0603/SOD-523F package, while CDBU0230, CDBU0230-HF, and CDBU0230L-HF use the 0603C/SOD-523F package. Both package variants are mechanically compatible 2-SMD, no-lead surface mount configurations. The "C" designation in the 0603C variant indicates a tape and reel packaging specification difference; both are suitable for automated assembly.

Reverse Leakage Specification: CDBUR0230 and CDBU0230 specify reverse leakage current at 30V, while CDBU0230L-HF and CDBUR0230L specify reverse leakage at 10V. Both specifications meet the 30 µA maximum requirement and are electrically equivalent for circuit operation.

Inventory Availability: CDBU0230-HF offers the highest inventory level (16,952 pcs), followed by CDBUR0230L (10,794 pcs), CDBU0230L-HF (6,635 pcs), CDBU0230 (4,291 pcs), and CDBUR0230 (797 pcs). Selection may be influenced by supply chain requirements and lead time considerations.

All parts maintain identical electrical performance across voltage, current, forward voltage drop, and temperature specifications, ensuring direct functional substitution in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CDBU0230 be used as a direct replacement for CDBUR0230?

A: Yes. CDBU0230 is a parametric equivalent with identical electrical specifications (30V reverse voltage, 200mA average rectified current, 500mV forward voltage drop at 200mA, 30µA reverse leakage at 30V, and 125°C maximum junction temperature). The primary difference is the supplier device package designation (0603C/SOD-523F versus 0603/SOD-523F), which represents a tape and reel packaging specification variation. Both are 2-SMD, no-lead surface mount packages suitable for automated assembly.

Q: What is the difference between CDBU0230-HF and CDBU0230L-HF?

A: Both parts are parametric equivalents with identical electrical ratings. The primary difference is the reverse leakage current specification: CDBU0230-HF specifies 30µA @ 30V, while CDBU0230L-HF specifies 30µA @ 10V. Both meet the maximum 30µA requirement and are electrically equivalent for circuit operation. CDBU0230-HF has higher inventory availability (16,952 pcs versus 6,635 pcs).

Q: Are the 0603 and 0603C package variants mechanically compatible?

A: Yes. Both 0603/SOD-523F and 0603C/SOD-523F are 2-SMD, no-lead surface mount packages with identical mechanical footprints and land patterns. The "C" designation indicates a tape and reel packaging specification difference, not a physical component difference. Both are suitable for the same PCB assembly processes.

Q: Can I substitute CDBUR0230L for CDBUR0230?

A: Yes. CDBUR0230L is a parametric equivalent with matching electrical specifications. Both use the 0603/SOD-523F package. The difference in reverse leakage specification (30µA @ 10V for CDBUR0230L versus 30µA @ 30V for CDBUR0230) does not affect circuit compatibility, as both meet the maximum 30µA requirement. CDBUR0230L offers significantly higher inventory (10,794 pcs versus 797 pcs).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts—CDBU0230, CDBU0230-HF, CDBU0230L-HF, and CDBUR0230L—are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and REACH unaffected status, matching the compliance profile of CDBUR0230.

Q: What determines whether a part can substitute for CDBUR0230?

A: Substitution is determined by equivalence across three criteria: (1) Electrical parameters—30V reverse voltage, 200mA average rectified current, 500mV forward voltage drop at 200mA, 30µA reverse leakage, and 125°C maximum junction temperature; (2) Mechanical parameters—surface mount, 2-SMD no-lead package, 0603/SOD-523F or 0603C/SOD-523F; (3) Compliance parameters—Schottky technology, ROHS3 compliance, MSL 1, and REACH unaffected status. All identified parts meet these criteria.
