Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDBU0230L-HF is determined by the following criteria:

Primary Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 500 mV @ 200 mA
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: 2-SMD, No Lead
• Operating Temperature - Junction (Max): 125°C

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99

All identified substitute parts maintain identical electrical performance specifications and regulatory compliance status. Package designations (0603C/SOD-523F versus 0603/SOD-523F) represent equivalent footprints within the SOD-523F form factor family.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full parametric equivalence to the CDBU0230L-HF across critical electrical specifications: reverse voltage rating, average rectified current, forward voltage drop, and reverse leakage current. Each part carries Active product status and ROHS3 compliance certification, confirming ongoing manufacturing support and regulatory alignment.

Selection Basis:

• CDBU0230-HF: Highest current inventory (16,952 pcs). Identical electrical specifications and package designation (0603C/SOD-523F). Recommended for applications requiring maximum supply availability.

• CDBUR0230L: Substantial inventory (10,794 pcs). Equivalent electrical performance with package designation 0603/SOD-523F, representing the standard SOD-523F footprint variant. Suitable for designs with flexible package tolerance specifications.

• CDBU0230: Lower inventory (4,291 pcs). Identical specifications to CDBU0230-HF. Selection appropriate when supply constraints on primary variants exist.

All parts are manufactured by Comchip Technology under identical compliance frameworks (REACH Unaffected, EAR99 classification, MSL Level 1).

Frequently Asked Questions (FAQ)

Q: Can CDBU0230-HF be directly replaced with CDBU0230 or CDBUR0230L?

A: Yes. All three parts share identical electrical specifications (30V reverse voltage, 200mA average rectified current, 500mV forward voltage drop at 200mA). Package footprints (0603C/SOD-523F and 0603/SOD-523F) are mechanically compatible within the SOD-523F form factor family. Direct substitution is supported for circuit applications.

Q: What is the difference between 0603C/SOD-523F and 0603/SOD-523F package designations?

A: Both designations reference the SOD-523F surface mount package with 2-SMD, No Lead configuration. The "C" suffix in 0603C represents a specific supplier package variant. Both are mechanically and electrically compatible for PCB assembly and circuit operation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CDBU0230L-HF, CDBU0230, CDBU0230-HF, and CDBUR0230L all carry ROHS3 Compliant certification. All parts are REACH Unaffected and classified under ECCN EAR99.

Q: What is the Moisture Sensitivity Level (MSL) for these diodes?

A: All parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard PCB assembly processes apply without special moisture control requirements.

Q: Which substitute part offers the best availability?

A: CDBU0230-HF maintains the highest inventory level at 16,952 pcs, followed by CDBUR0230L at 10,794 pcs. Both are suitable for high-volume production requirements.

Q: Can these diodes be used interchangeably in existing designs?

A: Yes, provided the circuit design accommodates the 0603C/SOD-523F or 0603/SOD-523F package footprint. All electrical parameters (voltage, current, forward drop, leakage) are identical across all substitute parts, supporting direct functional replacement.
