DBLS102GHRDG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS102GHRDG is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation. This component is classified as a standard bridge rectifier rated for 100 V peak reverse voltage and 1 A average rectified current, packaged in a 4-SMD Gull Wing surface mount configuration. The part maintains Active product status and carries AEC-Q101 automotive qualification with ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative sources provide equivalent functionality for applications requiring component interchangeability, inventory availability, or supply chain flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DBLS102GHRDG is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Peak Reverse (Max): 100 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Diode Type: Single Phase
• Technology: Standard

Mechanical Equivalence Criteria:

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

Compliance Criteria:

• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts maintain these core parameters. Variations in reverse leakage current and packaging format (Cut Tape, Tape & Reel, or Bulk) do not affect functional equivalence for circuit-level performance.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and are suitable for direct replacement in applications currently using the DBLS102GHRDG.

DF01SA-E3/77 (Vishay General Semiconductor - Diodes Division): This part is supplied in Tape & Reel (TR) packaging format and carries ROHS3 compliance with MSL 1 rating. Electrical parameters are fully equivalent. This configuration is appropriate for high-volume production environments requiring reel-based component handling.

DF01S1 (Fairchild Semiconductor): This part is supplied in Bulk packaging format. Electrical parameters are fully equivalent. This configuration is appropriate for applications where packaging format flexibility is acceptable and reel-based handling is not required.

DF01S-E3/77 (Vishay General Semiconductor - Diodes Division): This part is supplied in Cut Tape (CT) & Digi-Reel® packaging format and carries ROHS3 compliance with MSL 1 rating. Electrical parameters are fully equivalent. This configuration provides intermediate packaging flexibility between bulk and full reel quantities.

Component selection among these substitutes is determined by packaging requirements, inventory availability, and supply chain logistics rather than electrical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can DF01SA-E3/77 be used as a direct replacement for DBLS102GHRDG?

A: Yes. Both parts share identical electrical specifications (100 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A), identical operating temperature range (-55°C to 150°C), and identical mechanical packaging (4-SMD Gull Wing surface mount). The primary difference is packaging format (Tape & Reel versus the original supplier's format).

Q: What is the difference between DF01S-E3/77 and DF01SA-E3/77?

A: Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications and compliance ratings. The difference is packaging format: DF01S-E3/77 is supplied in Cut Tape (CT) & Digi-Reel® format, while DF01SA-E3/77 is supplied in Tape & Reel (TR) format. Electrical performance is equivalent.

Q: Is DF01S1 from Fairchild Semiconductor equivalent to DBLS102GHRDG?

A: Yes. DF01S1 maintains all critical electrical parameters (100 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A) and operating temperature range (-55°C to 150°C). The part is supplied in Bulk packaging format rather than reel-based formats.

Q: Does reverse leakage current variation affect substitution eligibility?

A: No. The DBLS102GHRDG specifies 2 µA reverse leakage at 100 V, while substitute parts specify 3 µA or 5 µA at the same conditions. These variations remain within acceptable operating parameters for bridge rectifier applications and do not affect functional equivalence at the circuit level.

Q: Are all substitute parts RoHS3 compliant?

A: DF01SA-E3/77 and DF01S-E3/77 are explicitly specified as ROHS3 Compliant. DF01S1 does not include RoHS status in the provided specifications. Applications requiring RoHS3 compliance should prioritize DF01SA-E3/77 or DF01S-E3/77.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates Moisture Sensitivity Level 1, which means the component has unlimited shelf life and does not require special moisture control during storage or handling. DF01SA-E3/77 and DF01S-E3/77 carry this rating. DF01S1 does not include MSL specification in the provided data.

Q: Can packaging format be changed during production without circuit redesign?

A: Yes. All substitute parts use identical 4-SMD Gull Wing surface mount packaging. Packaging format differences (Cut Tape, Tape & Reel, or Bulk) refer to how components are supplied and handled during assembly, not the physical component package itself. PCB footprints and solder pad layouts remain identical.
