Substitution of the CDBF0140L-HF is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• 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

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Surface Mount
• Package / Case: 1005 (2512 Metric)
• Supplier Device Package: 1005/SOD-323F

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Operating Temperature - Junction (Max): 125°C

The substitute part CDBFR0140L meets all electrical, mechanical, and compliance requirements and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CDBFR0140L is a direct parametric equivalent to the CDBF0140L-HF. Both components are manufactured by Comchip Technology and share identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction between these parts is packaging format: CDBF0140L-HF is supplied in standard packaging, while CDBFR0140L is available in Cut Tape (CT) and Digi-Reel® packaging options.

Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. The identical operating temperature junction maximum of 125°C confirms thermal performance equivalence.

Selection between these parts should be based on packaging requirements and inventory availability. Current inventory status shows CDBF0140L-HF with 20,400 pieces in stock and CDBFR0140L with 925 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can CDBFR0140L be used as a direct replacement for CDBF0140L-HF in existing designs?

A: Yes. The CDBFR0140L is a parametric equivalent with identical electrical characteristics, voltage ratings, current ratings, forward voltage drop, reverse leakage current, and capacitance specifications. Both components use the same 1005/SOD-323F package and mounting technology.

Q: What is the difference between CDBF0140L-HF and CDBFR0140L?

A: The electrical and mechanical specifications are identical. The difference lies in packaging format: CDBF0140L-HF uses standard packaging, while CDBFR0140L is supplied in Cut Tape (CT) and Digi-Reel® formats. This distinction affects handling, storage, and automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both CDBF0140L-HF and CDBFR0140L are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the obsolete product status?

A: Both parts are classified as obsolete. This designation indicates that the manufacturer has discontinued active production and support. Existing inventory from authorized distributors remains available, but long-term supply cannot be guaranteed. Design teams should evaluate long-term component availability when planning production schedules.

Q: Can these Schottky diodes be used in high-frequency switching applications?

A: These components are classified as Small Signal diodes with current ratings ≤200mA. The 40V reverse voltage rating and 100mA average rectified current define their operational envelope. Application suitability depends on specific circuit requirements and operating conditions.

Q: What are the storage and handling requirements?

A: Both parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard electronic component storage practices apply: maintain ambient temperature between 16°C and 35°C with relative humidity between 45% and 75%.
