Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDBFR0240-HF is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters (Critical for Substitution):

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 550 mV @ 200 mA
• Current - Reverse Leakage @ Vr: 10 µA @ 30 V
• Capacitance @ Vr, F: 9 pF @ 10V, 1MHz
• Operating Temperature - Junction (Max): 125°C
• Technology: Schottky

Mechanical Parameters (Critical for Substitution):

• Mounting Type: Surface Mount
• Package / Case: 1005/SOD-323F
• Supplier Device Package: 1005/SOD-323F

Substitute parts must match all electrical specifications and maintain compatibility with the 1005/SOD-323F package footprint and mounting requirements. Packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The CDBF0240-HF is the direct substitute for the obsolete CDBFR0240-HF. Both components are manufactured by Comchip Technology and share identical electrical specifications and package designations.

Selection Basis:

The CDBF0240-HF meets all substitution criteria:

• All electrical parameters match exactly: 40 V reverse voltage, 200 mA average rectified current, 550 mV forward voltage drop, 10 µA reverse leakage, and 9 pF capacitance.
• Package compatibility is maintained through the 1005/SOD-323F supplier device package designation.
• Surface mount mounting type and footprint are identical.
• Operating temperature range is identical at 125°C maximum junction temperature.
• Regulatory compliance is equivalent: both are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification.

The primary distinction is product status: CDBF0240-HF is active and available, while CDBFR0240-HF is obsolete. The CDBF0240-HF is supplied in Tape & Reel packaging format, which is standard for production environments and does not affect electrical or mechanical performance.
