Frequently Asked Questions (FAQ)

Q: Can RS1BB-13-F replace FR1B-13-F in existing designs?

A: Yes. RS1BB-13-F is electrically and mechanically equivalent to FR1B-13-F. Both parts share identical voltage ratings (100 V), current ratings (1 A), forward voltage characteristics (1.3 V @ 1 A), reverse recovery time (150 ns), and reverse leakage current (5 µA @ 100 V). Both use the DO-214AA SMB package for Surface Mount applications. Direct substitution is supported without PCB layout or schematic modification.

Q: What is the difference between FR1B-13-F and RS1BB-13-F?

A: The primary differences are product status and operating temperature range. FR1B-13-F is Obsolete with an operating temperature range of -65°C to 175°C. RS1BB-13-F is Active with an operating temperature range of -65°C to 150°C. All electrical specifications and mechanical parameters are identical. RS1BB-13-F is supplied in Tape & Reel packaging, while FR1B-13-F packaging is unspecified.

Q: Can FR1B (SMC Diode Solutions) replace FR1B-13-F (Diodes Incorporated)?

A: Yes. FR1B is electrically and mechanically equivalent to FR1B-13-F. Both parts share identical voltage ratings (100 V), current ratings (1 A), forward voltage characteristics (1.3 V @ 1 A), reverse recovery time (150 ns), and reverse leakage current (5 µA @ 100 V). Both use the DO-214AA SMB package for Surface Mount applications. The operating temperature range for FR1B is -50°C to 150°C, which is narrower than FR1B-13-F (-65°C to 175°C). Direct substitution is supported for applications within the -50°C to 150°C temperature range.

Q: Are there packaging differences between substitute parts?

A: RS1BB-13-F and FR1B are supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly. FR1B-13-F packaging type is not specified in the provided data. All three parts use the DO-214AA SMB package case, ensuring identical PCB footprint and mounting compatibility.

Q: What compliance certifications apply to these substitute parts?

A: All three parts are ROHS3 Compliant and carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions. RS1BB-13-F is REACH Unaffected. FR1B-13-F and FR1B are REACH Affected. All parts carry ECCN classification EAR99 and HTSUS code 8541.10.0080.

Q: Which substitute part should be selected for high-temperature applications?

A: FR1B-13-F supports the widest operating temperature range (-65°C to 175°C). However, FR1B-13-F is Obsolete. For active products, RS1BB-13-F supports -65°C to 150°C, and FR1B supports -50°C to 150°C. Selection depends on specific application temperature requirements and availability constraints.
