DBLS152GHC1G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS152GHC1G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 100 V peak reverse voltage and 1.5 A average rectified current. This component operates across the temperature range of -55°C to 150°C and is qualified to AEC-Q101 automotive standards. The part is currently active in production with 894 units in stock inventory.

Bridge rectifiers are essential components in power supply circuits for converting alternating current to direct current. Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or inventory depletion. Equivalent alternatives must maintain identical electrical performance and mechanical compatibility to ensure seamless integration into existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBLS152GHC1G are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Voltage - Peak Reverse (Max): 100 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 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

Compliance Parameters (Must Match):

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

The substitute parts DF1501S-E3/45 and DFL1501S-E3/45, both manufactured by Vishay General Semiconductor - Diodes Division, satisfy all mandatory electrical and mechanical requirements. Both alternatives are active products with ROHS3 compliance and identical MSL ratings.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts DF1501S-E3/45 and DFL1501S-E3/45 are functionally equivalent to the DBLS152GHC1G for applications requiring a 100 V, 1.5 A single-phase bridge rectifier in a 4-SMD gull wing surface mount package.

Selection Criteria Based on Provided Data:

The DBLS152GHC1G carries AEC-Q101 automotive qualification, indicating suitability for automotive applications. The substitute parts from Vishay do not list AEC-Q101 qualification in the provided specifications. For applications requiring automotive-grade components with AEC-Q101 certification, the original DBLS152GHC1G remains the specified choice.

For non-automotive applications or where automotive qualification is not a design requirement, both Vishay alternatives satisfy all electrical and mechanical parameters. The reverse leakage current specification differs slightly (2 µA for DBLS152GHC1G versus 5 µA for both Vishay parts), remaining within acceptable tolerances for standard bridge rectifier applications.

Both substitute parts are active products with established inventory availability (5888 units for DF1501S-E3/45 and 4982 units for DFL1501S-E3/45), providing supply continuity. All three parts maintain ROHS3 compliance and MSL Level 1 ratings, ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can DF1501S-E3/45 and DFL1501S-E3/45 be used interchangeably with DBLS152GHC1G?

A: Both Vishay parts are electrically and mechanically equivalent to the DBLS152GHC1G for standard applications. They share identical voltage ratings (100 V), current ratings (1.5 A), forward voltage characteristics (1.1 V @ 1.5 A), operating temperature range (-55°C to 150°C), and package configuration (4-SMD, Gull Wing). The primary distinction is the automotive qualification status of the original part.

Q: What is the difference between DF1501S-E3/45 and DFL1501S-E3/45?

A: Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications and package configurations. The difference lies in the base product number designation (DF1501 versus DFL1501) and packaging format (both specified as Tube). Both are active products with comparable inventory levels.

Q: Does the reverse leakage current difference affect substitution?

A: The DBLS152GHC1G specifies 2 µA reverse leakage at 100 V, while both Vishay substitutes specify 5 µA at 100 V. This difference remains within acceptable tolerances for standard bridge rectifier applications and does not prevent functional substitution in typical power supply circuits.

Q: Are these parts suitable for automotive applications?

A: The DBLS152GHC1G carries AEC-Q101 automotive qualification. The provided specifications for DF1501S-E3/45 and DFL1501S-E3/45 do not indicate AEC-Q101 certification. For applications requiring automotive-grade components with formal AEC-Q101 qualification, the original DBLS152GHC1G is the specified choice.

Q: What is the significance of the 4-SMD, Gull Wing package?

A: The 4-SMD (Surface Mount Device) gull wing package indicates a surface mount configuration with four leads in a gull wing style. All three parts share this identical package specification, ensuring mechanical compatibility with existing PCB layouts and reflow soldering processes.

Q: Are all three parts RoHS compliant?

A: Yes. The DBLS152GHC1G, DF1501S-E3/45, and DFL1501S-E3/45 are all ROHS3 compliant, meeting current environmental and material restriction requirements for electronic components.

Q: What does MSL Level 1 mean?

A: Moisture Sensitivity Level (MSL) 1 indicates unlimited shelf life without moisture control requirements. All three parts carry MSL Level 1 ratings, eliminating the need for specialized dry storage or baking procedures prior to assembly.
