Substitute Part Grouping Explanation

Substitution of the SDB107-TP-HF is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Diode Type: Single Phase (identical topology required)
• Technology: Standard (no advanced or specialized variants)
• Voltage - Peak Reverse (Max): 1 kV (exact match)
• Current - Average Rectified (Io): 1 A (exact match)
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A (exact match)
• Operating Temperature Range: -55°C ~ 150°C (TJ) (identical or wider range acceptable)

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount (required for PCB compatibility)
• Package / Case: 4-SMD, Gull Wing (identical footprint and lead configuration)

The substitute part DF10S1 from Fairchild Semiconductor meets all electrical and mechanical equivalence criteria, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SDB107-TP-HF and DF10S1 are classified as Active products, ensuring ongoing manufacturer support and availability. Both components carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, confirming equivalent regulatory and trade compliance status.

The DF10S1 demonstrates superior reverse leakage characteristics (3 µA @ 1 V) compared to the SDB107-TP-HF (10 µA @ 1000 V), indicating lower leakage current performance. This characteristic may provide operational advantages in applications sensitive to leakage current, though both parts satisfy the specified electrical requirements.

Selection between these parts should be based on procurement availability, lead time requirements, and cost considerations. The DF10S1 currently maintains higher inventory levels (10,300 Pcs) relative to the SDB107-TP-HF (729 Pcs), which may influence supply chain decisions.

Frequently Asked Questions (FAQ)

Q: Can the DF10S1 be used as a direct replacement for the SDB107-TP-HF in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. The 4-SMD, Gull Wing package configuration is identical, enabling direct PCB footprint compatibility without design modification.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by exact equivalence in: Diode Type (Single Phase), Technology (Standard), Voltage - Peak Reverse (1 kV), Current - Average Rectified (1 A), Voltage - Forward (1.1 V @ 1 A), Operating Temperature Range (-55°C ~ 150°C), Mounting Type (Surface Mount), and Package configuration (4-SMD, Gull Wing).

Q: Are there differences in leakage current between these parts?

A: Yes. The DF10S1 exhibits 3 µA reverse leakage @ 1 V, while the SDB107-TP-HF exhibits 10 µA @ 1000 V. Both values are within acceptable operating parameters for standard bridge rectifier applications.

Q: Do both parts comply with the same regulatory classifications?

A: Yes. Both the SDB107-TP-HF and DF10S1 carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, confirming equivalent export control and tariff status.

Q: What packaging format is used for each part?

A: Both parts use 4-SMD, Gull Wing surface mount packaging. The SDB107-TP-HF is supplied in the SDB-1 package format, while the DF10S1 uses the 4-SDIP supplier device package designation. Both are functionally equivalent for PCB assembly.
