DBLS106GHC1G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS106GHC1G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 800 V peak reverse voltage and 1 A average rectified current. This surface mount diode operates across the temperature range of -55°C to 150°C and is qualified to AEC-Q101 automotive standards. The component is currently in active product status with 875 pieces available in inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the critical parameters that define bridge rectifier functionality. Alternative sources become necessary due to supply chain considerations, inventory availability, or design flexibility requirements while maintaining identical electrical specifications and operating characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBLS106GHC1G are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Peak Reverse (Max): 800 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 Equivalence Criteria:

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

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical ratings and mechanical compatibility. Variations in reverse leakage current (Current - Reverse Leakage @ Vr) remain within acceptable operational parameters for bridge rectifier applications. Substitute parts are sourced from qualified manufacturers including Comchip Technology, Vishay General Semiconductor - Diodes Division, and Panjit International Inc.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: DBLS106GHC1G (Taiwan Semiconductor Corporation)

The DBLS106GHC1G maintains active product status with established supply chain availability (875 pieces in stock). This component carries AEC-Q101 automotive qualification, making it the preferred choice for applications requiring automotive-grade reliability and traceability.

Active Substitute Options:

DF08S-E3/45 (Vishay General Semiconductor - Diodes Division) is recommended as the primary substitute when supply constraints affect the DBLS106GHC1G. This part maintains active product status with the highest inventory availability (5750 pieces). All electrical parameters and mechanical specifications are equivalent. Packaging is supplied in tube format.

DI108S_T0_00001 (Panjit International Inc.) serves as an alternative active substitute with equivalent electrical and mechanical specifications. This component is available in 985 pieces and maintains active product status. Packaging is supplied in tube format with 4-SDIP supplier device package designation.

Obsolete Status Consideration:

DB106S-G (Comchip Technology) is identified as obsolete and should not be selected for new designs or long-term production requirements. While electrical and mechanical parameters remain equivalent, the obsolete status creates supply chain risk and limits future availability.

Selection between active substitutes should be based on inventory availability, packaging format requirements, and established supplier relationships within the design organization.

Frequently Asked Questions (FAQ)

Q: Can the DB106S-G be used as a substitute despite its obsolete status?

A: The DB106S-G maintains electrical and mechanical equivalence to the DBLS106GHC1G. However, obsolete product status indicates discontinued manufacturing and limited future availability. Selection of this part introduces supply chain risk for production quantities and long-term support. Active alternatives (DF08S-E3/45 or DI108S_T0_00001) are recommended for new designs.

Q: What is the significance of the reverse leakage current variation among substitute parts?

A: The DBLS106GHC1G specifies 2 µA reverse leakage at 800 V, while substitute parts range from 5 µA to 10 µA at the same voltage. All values remain within acceptable operational parameters for standard bridge rectifier applications. The variation reflects different manufacturing processes across suppliers but does not affect functional compatibility in typical rectification circuits.

Q: Are all substitute parts qualified to the same automotive standards?

A: The DBLS106GHC1G carries AEC-Q101 automotive qualification. The substitute parts (DF08S-E3/45 and DI108S_T0_00001) do not list AEC-Q101 qualification in the provided specifications. Applications requiring automotive-grade qualification should verify additional certification requirements with the respective manufacturers before substitution.

Q: What packaging format differences exist among the substitute parts?

A: The DBLS106GHC1G is supplied in standard packaging format. DF08S-E3/45 is supplied in tube packaging. DI108S_T0_00001 is supplied in tube packaging with 4-SDIP supplier device package designation. All parts maintain identical 4-SMD, Gull Wing case configuration for PCB mounting compatibility.

Q: Can these parts be used interchangeably on the same PCB layout?

A: Yes. All parts maintain identical 4-SMD, Gull Wing package configuration and surface mount mounting type. PCB footprints, solder pad layouts, and assembly processes remain unchanged across all substitute parts. No design modifications are required for mechanical or electrical integration.

Q: What compliance certifications apply to all substitute parts?

A: All parts (DBLS106GHC1G, DB106S-G, DF08S-E3/45, and DI108S_T0_00001) are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture control requirements during storage or handling.
