Substitute Part Grouping Explanation

Substitution of the CDBU0140L-HF is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CDBUR0140L meets substitution criteria based on the following key parameters:

Electrical Equivalence:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 100 mA
• Voltage - Forward (Vf) (Max) @ If: 550 mV @ 100 mA
• Current - Reverse Leakage @ Vr: 30 µA @ 10 V
• Capacitance @ Vr, F: 6 pF @ 10V, 1MHz
• Operating Temperature - Junction (Max): 125°C

Mechanical Equivalence:

• Mounting Type: Surface Mount
• Package / Case: 2-SMD, No Lead
• Technology: Schottky
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Compliance Equivalence:

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

The substitute part differs only in the supplier device package designation (0603 versus 0603C), which represents a minor packaging variant within the same SOD-523F footprint standard. Both parts are manufactured by Comchip Technology and maintain identical electrical performance and thermal characteristics.
