Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B05S-HF is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 800 mA
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 800 mA
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Surface Mount
• Package / Case: TO-269AA, 4-BESOP
• Technology: Standard

The B05S-G meets all electrical and mechanical parameters required for direct substitution with the B05S-HF. Both components share identical electrical specifications, package configuration, and thermal operating range. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The B05S-HF is the preferred selection for new designs and production applications due to its active product status and higher inventory availability. The B05S-G remains electrically and mechanically equivalent and is suitable for replacement applications where existing designs specify this component. However, the B05S-G is classified as obsolete, which may impact long-term supply chain reliability.

Both components maintain full compliance with ROHS3 and REACH regulations, ensuring environmental and regulatory conformance. The identical electrical performance, thermal operating range, and package configuration of both parts enable direct substitution without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can B05S-G replace B05S-HF in existing designs? A: Yes. The B05S-G is electrically and mechanically equivalent to the B05S-HF. All critical parameters including voltage rating, current capacity, forward voltage drop, and operating temperature range are identical. The components share the same TO-269AA, 4-BESOP package configuration and require no circuit modifications.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging is supplied on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape (CT) & Digi-Reel® packaging is supplied in shorter tape segments, typically used for lower-volume applications or manual assembly. Both formats contain the same component with identical electrical specifications.

Q: Why is B05S-G listed as obsolete? A: Product obsolescence indicates that the B05S-G is no longer in active production. For new designs and long-term supply requirements, the B05S-HF is recommended due to its active status and sustained manufacturing support.

Q: Are there any compliance differences between B05S-HF and B05S-G? A: No. Both components are ROHS3 compliant and REACH unaffected. They share identical moisture sensitivity levels (MSL 1 - Unlimited) and environmental certifications.

Q: Can these components be used interchangeably in production? A: Yes, provided the packaging format (Tape & Reel versus Cut Tape) is compatible with your assembly process. The electrical performance and thermal characteristics are identical, enabling direct substitution without functional impact.
