Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF201ST-G is determined by strict equivalence across the following electrical and mechanical parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 100 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
• Current - Reverse Leakage @ Vr: 10 µA @ 100 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing

The DF201S-G meets all specified electrical and mechanical requirements for direct substitution. Both parts share identical base product designation (DF201) and maintain equivalent performance characteristics across all rated parameters.

Engineering Selection Recommendations

The DF201S-G is the manufacturer-recommended substitute for the obsolete DF201ST-G. Both components maintain identical electrical specifications and mechanical packaging, ensuring direct functional equivalence. The DF201S-G carries active product status, providing ongoing availability and supply chain continuity. Both parts satisfy ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment for applications requiring environmental and hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Can DF201S-G replace DF201ST-G in existing designs? A: Yes. The DF201S-G provides electrical and mechanical equivalence across all specified parameters, including voltage rating, current capacity, forward voltage drop, reverse leakage current, operating temperature range, and 4-SMD Gull Wing packaging.

Q: What is the primary difference between these parts? A: The DF201ST-G is obsolete, while the DF201S-G maintains active product status. Packaging designation differs (DFS supplier device package remains identical), but electrical performance is equivalent.

Q: Are there packaging or handling differences? A: The DF201S-G is supplied in tube packaging, whereas the DF201ST-G packaging type was not specified. Both components maintain MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special moisture control requirements during storage or handling.

Q: Do compliance certifications remain valid with substitution? A: Yes. Both parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance for applications subject to these standards.
