Engineering Selection Recommendations

Primary Substitute: B160-13-F (Diodes Incorporated)

The B160-13-F is the direct functional equivalent for the obsolete CDBB160SLR-HF. Selection rationale:

• Product Status: B160-13-F is classified as Active with continuous manufacturing availability, eliminating supply chain risk associated with the obsolete CDBB160SLR-HF.
• Compliance: B160-13-F holds RoHS3 Compliant certification, meeting current regulatory requirements. Both parts are REACH Unaffected and carry EAR99 ECCN classification.
• Electrical Equivalence: Both devices share identical voltage ratings (60V), current ratings (1A), fast recovery speed characteristics, and package specifications (DO-214AC/SMA).
• Performance Advantages: B160-13-F demonstrates lower reverse leakage current (500 µA vs. 1 mA @ 60V) and extended operating temperature range (-65°C to 150°C vs. -50°C to 150°C), providing improved performance margins in thermal and leakage-sensitive applications.
• Packaging: Both parts utilize identical surface mount DO-214AC (SMA) packaging, enabling direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can B160-13-F be used as a direct replacement for CDBB160SLR-HF without circuit modification?

A: Yes. Both devices share identical voltage ratings (60V), current ratings (1A), fast recovery speed characteristics (≤500ns), and DO-214AC (SMA) package specifications. Direct substitution is electrically and mechanically compatible.

Q: What are the differences in forward voltage between these parts?

A: CDBB160SLR-HF specifies 500 mV maximum forward voltage at 2A, while B160-13-F specifies 700 mV maximum at 1A. These measurements are taken at different current levels. The B160-13-F's lower reverse leakage current (500 µA vs. 1 mA) represents an operational advantage in low-leakage applications.

Q: Are there packaging differences between CDBB160SLR-HF and B160-13-F?

A: Both parts use identical DO-214AC (SMA) surface mount packaging. No PCB layout modifications are required for substitution.

Q: Does B160-13-F meet current regulatory requirements?

A: Yes. B160-13-F is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards. CDBB160SLR-HF is classified as obsolete and no longer manufactured.

Q: What is the temperature operating range difference?

A: CDBB160SLR-HF operates from -50°C to 150°C junction temperature. B160-13-F extends the lower limit to -65°C, providing improved performance in cold-temperature environments.

Q: Is B160-13-F available in the same packaging format as CDBB160SLR-HF?

A: Yes. B160-13-F is supplied in Cut Tape (CT) and Digi-Reel® packaging options, both compatible with standard surface mount assembly processes. The component footprint and solder pad configuration are identical to CDBB160SLR-HF.

Q: What is the reverse leakage current difference, and does it affect circuit design?

A: B160-13-F exhibits 500 µA reverse leakage at 60V, compared to 1 mA for CDBB160SLR-HF. This lower leakage in B160-13-F provides improved performance in precision rectification and low-power applications where leakage current contributes to overall circuit power consumption.
