Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBLS103GHRDG are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Peak Reverse (Max): 200 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
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing

All identified substitute parts meet or exceed these electrical specifications and share identical mechanical mounting characteristics. Variations in reverse leakage current and packaging format (Cut Tape, Tape & Reel, or Bulk) do not affect functional equivalence for circuit operation.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—DF02S-E3/77, DF02SA-E3/77, and DF02S1—are functionally equivalent to the DBLS103GHRDG for direct circuit replacement. Selection among these alternatives is determined by availability, packaging format requirements, and compliance certifications applicable to the end application.

DF02S-E3/77 (Vishay): Available in Cut Tape & Digi-Reel® packaging with 30,300 units in stock. RoHS3 compliant and MSL 1 rated. Highest inventory availability.

DF02SA-E3/77 (Vishay): Available in Tape & Reel format with 2,100 units in stock. RoHS3 compliant and MSL 1 rated. Suitable for automated assembly processes requiring reel packaging.

DF02S1 (Fairchild Semiconductor): Available in Bulk packaging with 10,200 units in stock. Compliance certifications not specified in available data. Suitable for applications where packaging format is not a constraint.

For automotive applications requiring AEC-Q101 qualification, the DBLS103GHRDG main part number is the specified choice. Substitute parts should be evaluated against specific application qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can DF02S-E3/77 replace DBLS103GHRDG in all applications?

A: Yes. The DF02S-E3/77 meets all critical electrical parameters: 200 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, and -55°C to 150°C operating temperature range. The 4-SMD Gull Wing package is mechanically identical. Reverse leakage current is 5 µA versus 2 µA for the main part, which remains within acceptable limits for standard bridge rectifier applications.

Q: What is the difference between DF02S-E3/77 and DF02SA-E3/77?

A: Both parts are manufactured by Vishay and share identical electrical specifications. The primary difference is packaging format: DF02S-E3/77 is supplied in Cut Tape & Digi-Reel® format, while DF02SA-E3/77 is supplied in Tape & Reel format. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Is DF02S1 suitable for automotive applications?

A: DF02S1 meets all electrical specifications required for the application. However, automotive qualification status is not specified in available documentation. Verification against specific automotive qualification requirements (such as AEC-Q101) is necessary before selection for automotive end-use.

Q: How do reverse leakage current differences affect substitution?

A: The main part specifies 2 µA reverse leakage at 200 V. Substitute parts specify 3 µA to 5 µA at the same conditions. These variations are within normal manufacturing tolerances for standard bridge rectifier technology and do not affect functional equivalence in typical circuit applications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All parts share the 4-SMD Gull Wing package configuration and identical pin assignments. PCB footprints and reflow soldering profiles are compatible. Packaging format (Cut Tape, Tape & Reel, or Bulk) affects handling and assembly logistics but not electrical or mechanical compatibility.

Q: What compliance certifications apply to all substitute parts?

A: DF02S-E3/77 and DF02SA-E3/77 are RoHS3 compliant with MSL 1 rating. DF02S1 compliance certifications are not specified in available data. REACH status is unaffected for Vishay parts. ECCN classification is EAR99 for all parts.
