DF01S-HF Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF01S-HF is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 100 V peak reverse voltage and 1 A average rectified current. This surface mount diode operates across a temperature range of -55°C to 150°C and is housed in a 4-SMD, Gull Wing package (DFS supplier device package). The part is currently in active product status with 909 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameters. Alternative sources provide identical functional characteristics while offering different packaging options, compliance certifications, or inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF01S-HF are qualified based on electrical parameter equivalence and mechanical compatibility. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Voltage - Peak Reverse (Max): 100 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Operating Temperature Range: -55°C to 150°C (TJ)
• Diode Type: Single Phase
• Technology: Standard

Mechanical Parameters (Must Match):

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

The substitute parts DF01S-E3/45 and DF01SA-E3/45, both manufactured by Vishay General Semiconductor - Diodes Division, meet all electrical and mechanical requirements. Both parts maintain identical peak reverse voltage, average rectified current, forward voltage characteristics, and operating temperature specifications. Current - Reverse Leakage @ Vr is lower in the Vishay alternatives (5 µA @ 100 V versus 10 µA @ 100 V in the Comchip part), which represents improved performance within the same functional class.

Parameter Comparison

Engineering Selection Recommendations

All three parts—DF01S-HF, DF01S-E3/45, and DF01SA-E3/45—are active products with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Compliance and Certifications: The Vishay alternatives (DF01S-E3/45 and DF01SA-E3/45) carry ROHS3 compliance and REACH Unaffected status, with Moisture Sensitivity Level (MSL) rated at 1 (Unlimited). These certifications are provided in the component data for the Vishay parts.

Inventory and Packaging: The Comchip DF01S-HF offers 909 units in stock. The Vishay DF01S-E3/45 provides 5684 units in Tube packaging, and the Vishay DF01SA-E3/45 provides 5669 units in Tube packaging. Packaging format (Tube versus unspecified for Comchip) may influence procurement workflows.

Performance Characteristics: The Vishay parts exhibit lower reverse leakage current (5 µA @ 100 V) compared to the Comchip part (10 µA @ 100 V), indicating improved leakage performance within the same functional rating.

Frequently Asked Questions (FAQ)

Q: Can DF01S-E3/45 or DF01SA-E3/45 be used as direct replacements for DF01S-HF?

A: Yes. Both Vishay parts maintain identical electrical ratings (100 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A) and mechanical specifications (4-SMD Gull Wing surface mount package). All three parts operate across -55°C to 150°C and are classified as single-phase standard technology bridge rectifiers.

Q: What is the difference between DF01S-E3/45 and DF01SA-E3/45?

A: Both parts are manufactured by Vishay and share identical electrical parameters and package specifications. The designation difference (DF01S versus DF01SA) reflects Vishay's internal product line differentiation. Both are functionally equivalent for the specified application.

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

A: The Comchip DF01S-HF specifies 10 µA @ 100 V reverse leakage current. Both Vishay alternatives (DF01S-E3/45 and DF01SA-E3/45) specify 5 µA @ 100 V, representing lower leakage performance. This difference does not affect functional compatibility but indicates improved electrical characteristics in the Vishay parts.

Q: What packaging formats are available?

A: The Comchip DF01S-HF packaging format is not specified in the provided data. The Vishay DF01S-E3/45 and DF01SA-E3/45 are supplied in Tube packaging. Both maintain the same 4-SMD, Gull Wing physical package configuration suitable for surface mount assembly.

Q: Are all three parts compliant with environmental and trade regulations?

A: All three parts carry EAR99 ECCN classification and 8541.10.0080 HTSUS code. The Vishay parts include ROHS3 compliance and REACH Unaffected status. The Comchip part's compliance certifications are not detailed in the provided data.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical and mechanical specifications are identical across all three parts. PCB layouts, thermal management, and circuit design considerations remain unchanged. No design modifications are required for substitution.
