Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDBWL0130LR-HF is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 30V
• Current - Average Rectified (Io): 100mA
• Package / Case: 01005 (0402 Metric)
• Mounting Type: Surface Mount
• Technology: Schottky
• Operating Temperature Range: -55°C to 125°C
• RoHS Compliance: ROHS3 Compliant

The CDBWL521-HF meets all mandatory criteria for direct substitution. Both parts share identical reverse voltage ratings, average rectified current specifications, package geometry, and thermal operating range. Both components are manufactured by Comchip Technology and maintain ROHS3 compliance with MSL 1 moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

Both the CDBWL0130LR-HF and CDBWL521-HF are Active products with full ROHS3 compliance and MSL 1 rating, indicating unlimited shelf life under standard storage conditions. Selection between these parts is based on application-specific requirements and inventory availability.

The CDBWL0130LR-HF is specified with forward voltage of 460mV at 100mA and reverse leakage of 20µA at 30V. The CDBWL521-HF exhibits lower forward voltage (300mV at 10mA) and lower reverse leakage (7µA at 10V), indicating improved efficiency characteristics at lower current levels. Both parts maintain identical voltage and current ratings, package specifications, and temperature operating range.

Selection should account for circuit operating conditions, thermal dissipation requirements, and forward voltage drop impact on system performance. Both parts are suitable for direct substitution in applications where the 01005 package and 30V/100mA ratings are specified.

Frequently Asked Questions (FAQ)

Q: Can CDBWL521-HF replace CDBWL0130LR-HF in existing designs?

A: Yes. Both parts share identical voltage ratings (30V), current ratings (100mA), package geometry (01005/0402 Metric), mounting type (Surface Mount), and operating temperature range (-55°C to 125°C). Direct substitution is electrically and mechanically compatible.

Q: What are the differences between these two parts?

A: The primary differences are forward voltage and reverse leakage characteristics.
