Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDBURT0230LL-HF is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 20 V
• Package / Case: SC-79, SOD-523F (0603 form factor)
• Technology: Schottky
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 125°C
• RoHS3 Compliance

Allowable Variation Parameters:

• Current - Average Rectified (Io): Substitute must equal or exceed 200 mA
• Voltage - Forward (Vf) (Max): Substitute may vary within acceptable circuit design margins
• Current - Reverse Leakage @ Vr: Substitute may vary
• Capacitance @ Vr, F: Substitute may vary

The CDBURT0530LL-HF qualifies as a direct substitute because it maintains identical reverse voltage rating, package form factor, temperature range, and compliance certifications while providing higher current capacity (500 mA vs. 200 mA), making it suitable for applications requiring the original part's specifications or greater current handling.

Parameter Comparison

Engineering Selection Recommendations

The CDBURT0530LL-HF is the manufacturer-recommended substitute for the obsolete CDBURT0230LL-HF. Both parts maintain identical reverse voltage specifications (20V), identical package form factor (0603/SOD-523F), and identical operating temperature range (-55°C to 125°C). Both parts are RoHS3 compliant with MSL 1 rating and REACH unaffected status.

The primary difference is current capacity: the substitute part is rated for 500 mA average rectified current compared to the original 200 mA rating. This higher current rating provides design flexibility for applications at or below the original specification. The substitute part is currently in active production status with substantial inventory availability (26,653 pieces), ensuring procurement continuity.

Forward voltage characteristics differ due to the higher current rating of the substitute part (460 mV @ 500 mA vs. 390 mV @ 200 mA), which is expected behavior for Schottky diodes at different current levels. Reverse leakage current is higher in the substitute part (100 µA @ 20 V vs. 30 µA @ 10 V), reflecting the higher current capacity design.

Frequently Asked Questions (FAQ)

Q: Can the CDBURT0530LL-HF be used as a direct replacement for the CDBURT0230LL-HF?

A: Yes. Both parts share identical reverse voltage rating (20V), package form factor (0603/SOD-523F), temperature range (-55°C to 125°C), and compliance certifications (RoHS3, REACH unaffected). The substitute part's higher current rating (500 mA vs. 200 mA) makes it suitable for applications requiring the original specification or greater current handling capacity.

Q: What are the key differences between these parts?

A: The primary differences are current capacity (500 mA vs. 200 mA), forward voltage at rated current (460 mV vs. 390 mV), reverse leakage current (100 µA vs. 30 µA), and product status (active vs. obsolete). The substitute part is designed for higher current applications while maintaining the same voltage and package specifications.

Q: Are the packages physically identical?

A: Both parts use the 0603/SOD-523F form factor for surface mount assembly. The package designation differs slightly (SC-79 vs. 2-SMD, No Lead), but both refer to the same physical 0603 package size suitable for identical PCB layouts.

Q: What is the impact of higher reverse leakage current in the substitute part?

A: The CDBURT0530LL-HF exhibits higher reverse leakage current (100 µA @ 20 V) compared to the original part (30 µA @ 10 V). This is characteristic of higher-current-rated Schottky diodes. Circuit designers must verify that this leakage current is acceptable for their specific application requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CDBURT0230LL-HF and CDBURT0530LL-HF are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and REACH unaffected status.

Q: Why is the original part obsolete?

A: The CDBURT0230LL-HF is classified as obsolete by the manufacturer. The CDBURT0530LL-HF represents the active product line continuation, offering improved current capacity while maintaining backward compatibility with the original voltage and package specifications.
