Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF204SP-G is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters (Critical for Function):

• Voltage - Peak Reverse (Max): 400 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
• Current - Reverse Leakage @ Vr: 10 µA @ 400 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Mechanical Parameters (Critical for Assembly):

• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing

The DF204S-G meets all specified electrical and mechanical parameters, establishing direct substitution compatibility with the obsolete DF204SP-G.

Frequently Asked Questions (FAQ)

Q: Can the DF204S-G directly replace the DF204SP-G in existing designs?

A: Yes. The DF204S-G provides identical electrical performance and mechanical compatibility. All critical parameters including voltage rating, current capacity, forward voltage drop, reverse leakage current, and operating temperature range are equivalent.

Q: What is the primary reason for substitution?

A: The DF204SP-G is classified as obsolete. The DF204S-G is the active equivalent part from the same manufacturer, ensuring continued availability and supply chain support.

Q: Are there packaging differences between these parts?

A: Both components use identical 4-SMD Gull Wing surface mount packaging. The DF204S-G is supplied in Tube packaging, while the DF204SP-G packaging specification was not provided. This does not affect electrical or mechanical compatibility in circuit applications.

Q: What regulatory certifications apply to the DF204S-G?

A: The DF204S-G is ROHS3 Compliant and REACH Unaffected. It carries Moisture Sensitivity Level (MSL) 1 (Unlimited), requiring no special moisture control during storage and handling.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts operate across the identical temperature range of -55°C to 150°C (TJ) and maintain the same forward voltage (1.1 V @ 2 A) and reverse leakage current (10 µA @ 400 V) specifications.
