CDBC260LR-HF Schottky Diode Equivalent & Substitute Parts

Part Overview

The CDBC260LR-HF is an active Schottky rectifier diode manufactured by Comchip Technology, rated for 60V DC reverse voltage and 2A average rectified current in a surface mount DO-214AB (SMC) package. This component is designed for fast recovery applications with switching speeds ≤500ns and operates across a junction temperature range of -50°C to 150°C. The part is RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and maintains 751 pieces in current inventory stock.

Equivalent and substitute parts are identified when alternative manufacturers offer Schottky diodes with compatible electrical specifications and mechanical packaging that satisfy the same circuit requirements without design modification.

Substitute Part Grouping Explanation

Substitution of the CDBC260LR-HF is determined by the following critical electrical and mechanical parameters:

Mandatory Compatibility Criteria:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 60V
Package / Case: Must be DO-214AB or SMC equivalent
Technology: Schottky diode type
Mounting Type: Surface Mount
Speed Classification: Fast Recovery ≤500ns, >200mA (Io)
RoHS Compliance: ROHS3 Compliant

Current Rating Consideration: The CDBC260LR-HF is rated for 2A average rectified current. Substitute parts with equal or higher current ratings (Io ≥ 2A) are electrically compatible, as they can safely handle the specified load without exceeding thermal or electrical stress limits.

Secondary Parameters: Forward voltage (Vf), reverse leakage current, and capacitance are secondary parameters that may vary between substitutes while maintaining functional equivalence in the circuit application.

Engineering Selection Recommendations

B560C-13-F as Substitute for CDBC260LR-HF:

The B560C-13-F manufactured by Diodes Incorporated is electrically and mechanically compatible with the CDBC260LR-HF. Both devices share identical reverse voltage ratings (60V), identical package specifications (DO-214AB/SMC), identical fast recovery speed classification, and identical reverse leakage characteristics. Both are RoHS3 compliant with MSL 1 rating.

The B560C-13-F carries a higher current rating (5A versus 2A), which provides additional thermal margin in applications operating at or near the 2A specification of the CDBC260LR-HF. The substitute part's wider operating temperature range (-55°C to 150°C versus -50°C to 150°C) extends low-temperature performance capability.

Both parts are active products with current manufacturing status and full compliance documentation. The B560C-13-F maintains significantly higher inventory availability (227,807 pieces) compared to the CDBC260LR-HF (751 pieces), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the B560C-13-F directly replace the CDBC260LR-HF without PCB modification?

A: Yes. Both devices use identical DO-214AB (SMC) surface mount packaging with the same footprint, pin configuration, and land pattern. No PCB layout changes are required for mechanical or electrical substitution.

Q: Why does the B560C-13-F have a higher current rating (5A) than the CDBC260LR-HF (2A)?

A: The substitute part is designed for higher current applications. In circuits requiring only 2A operation, the B560C-13-F operates well within its thermal and electrical limits, providing design margin without performance degradation.

Q: Are the forward voltage characteristics identical between these parts?

A: No. The CDBC260LR-HF specifies 550 mV maximum forward voltage at 2A, while the B560C-13-F specifies 700 mV maximum at 5A. These measurements are taken at different current levels. At the 2A operating point of the CDBC260LR-HF circuit, the B560C-13-F forward voltage will differ from the specified 700 mV value.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the CDBC260LR-HF and B560C-13-F are RoHS3 compliant, carry MSL 1 (unlimited) moisture sensitivity rating, and are classified under identical ECCN (EAR99) and HTSUS (8541.10.0080) codes.

Q: What is the temperature operating range difference?

A: The B560C-13-F extends the minimum junction temperature to -55°C compared to the CDBC260LR-HF at -50°C. Both share the same maximum junction temperature of 150°C. This provides 5°C additional low-temperature margin with the substitute part.

Q: Are there any packaging format differences between these parts?

A: The CDBC260LR-HF is supplied in Tape & Reel (TR) format, while the B560C-13-F is available in Cut Tape (CT) and Digi-Reel® formats. Both formats are standard surface mount delivery methods with identical component specifications.
