Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 100 mA
• Voltage - Forward (Vf) (Max) @ If: 450 mV @ 10 mA
• Current - Reverse Leakage @ Vr: 500 nA @ 10 V
• Technology: Schottky
• Speed Classification: Small Signal ≤ 200 mA (Io), Any Speed

Mechanical Parameters (Must Match):

• Package / Case: 0402 (1006 Metric)
• Supplier Device Package: 0402C/SOD-923F
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Product Status: Active

The substitute parts CDBQC0140L-HF and CDBQC54-HF meet all specified criteria and are direct functional equivalents of the CDBQC0130R-HF.

Frequently Asked Questions (FAQ)

Q: Can CDBQC0140L-HF be used as a direct replacement for CDBQC0130R-HF?

A: Yes. Both parts are identical in all electrical parameters (30 V reverse voltage, 100 mA average rectified current, 450 mV forward voltage at 10 mA), mechanical packaging (0402/SOD-923F), and compliance certifications (RoHS3, MSL 1). No circuit modifications are required.

Q: Are there any differences in forward voltage characteristics between the three parts?

A: No. All three parts specify 450 mV maximum forward voltage at 10 mA forward current. Reverse leakage current is also identical at 500 nA @ 10 V across all parts.

Q: Do all substitute parts use the same package footprint?

A: Yes. CDBQC0130R-HF, CDBQC0140L-HF, and CDBQC54-HF all use the 0402 (1006 Metric) package with SOD-923F supplier device package designation. PCB footprints are identical.

Q: What is the moisture sensitivity rating for these diodes?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.

Q: Are these parts suitable for high-frequency switching applications?

A: These parts are classified as small signal diodes with current ratings ≤ 200 mA. They are suitable for applications within their specified electrical parameters. Specific frequency performance data is not provided in the parametric specifications.

Q: Can I mix different part numbers in the same production batch?

A: Yes. Since all three parts are electrically and mechanically equivalent with identical compliance certifications, they can be used interchangeably within the same design without functional impact.

Q: What is the maximum junction temperature for these diodes?

A: The maximum operating junction temperature is 125°C for all three parts.
