Substitute Part Grouping Explanation

Substitution of the DF208SP-G is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters (Critical for Functional Compatibility):

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 800 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
• Current - Reverse Leakage @ Vr: 10 µA @ 800 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Mechanical Parameters (Critical for Physical Compatibility):

• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Supplier Device Package: DFS

The DF208S-G meets all specified electrical and mechanical parameters, establishing it as a direct equivalent substitute for the obsolete DF208SP-G.

Engineering Selection Recommendations

The DF208S-G is the direct equivalent substitute for the obsolete DF208SP-G. Selection of the DF208S-G is based on the following factors:

Product Status: The DF208SP-G is classified as obsolete, while the DF208S-G maintains active product status, ensuring continued availability and manufacturing support.

Electrical Equivalence: All critical electrical parameters are identical between the two parts, including voltage ratings, current specifications, forward voltage characteristics, and reverse leakage current.

Mechanical Compatibility: Both parts share identical mounting type, package configuration, and supplier device package designation, ensuring direct physical compatibility in existing circuit board designs.

Regulatory Compliance: The DF208S-G provides ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The moisture sensitivity level of 1 (unlimited) indicates standard handling requirements.

Manufacturing Continuity: Both parts are manufactured by Comchip Technology under the same base product number (DF208), confirming design lineage and manufacturing consistency.

Frequently Asked Questions (FAQ)

Q: Can the DF208S-G be used as a direct replacement for the DF208SP-G in existing designs?

A: Yes. The DF208S-G is electrically and mechanically equivalent to the DF208SP-G. All electrical parameters, including voltage ratings, current specifications, and thermal characteristics, are identical. The package configuration and mounting type are also identical, enabling direct substitution without circuit board redesign.

Q: What is the difference between the DF208SP-G and DF208S-G part numbers?

A: The primary difference is product status. The DF208SP-G is obsolete, while the DF208S-G is active. The electrical and mechanical specifications are identical. The packaging format differs (the DF208S-G is supplied in tube packaging), but the component itself is functionally equivalent.

Q: Are there any compliance or certification differences between these parts?

A: The DF208S-G provides explicit ROHS3 compliance and REACH unaffected status certification. The DF208SP-G does not specify these certifications. Both parts share identical ECCN and HTSUS classifications.

Q: What is the moisture sensitivity level for the DF208S-G?

A: The DF208S-G has a moisture sensitivity level (MSL) of 1, which indicates unlimited shelf life and standard handling requirements without special moisture control measures.

Q: Are both parts manufactured by the same company?

A: Yes. Both the DF208SP-G and DF208S-G are manufactured by Comchip Technology and share the same base product number (DF208), confirming consistent design and manufacturing standards.

Q: What are the key electrical parameters that define this bridge rectifier?

A: The DF208SP-G and DF208S-G are single-phase standard bridge rectifiers with a peak reverse voltage of 800 V, average rectified current of 2 A, maximum forward voltage of 1.1 V at 2 A, reverse leakage current of 10 µA at 800 V, and operating temperature range of -55°C to 150°C.

Q: Is the package configuration the same for both parts?

A: Yes. Both parts use a 4-SMD, Gull Wing package configuration with DFS supplier device package designation, ensuring identical physical compatibility and PCB layout requirements.
