DBLS151GHRDG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS151GHRDG is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 50 V peak reverse voltage and 1.5 A average rectified current. This surface mount component operates across the temperature range of -55°C to 150°C and meets AEC-Q101 automotive qualification standards. The part is currently in active product status with 1087 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including voltage rating, current capacity, forward voltage characteristics, and package configuration. Alternative sources provide design flexibility, supply chain redundancy, and manufacturing options while preserving circuit functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DBLS151GHRDG is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Peak reverse voltage rating of 50 V
• Average rectified current capacity of 1.5 A
• Forward voltage drop at rated current not exceeding 1.1 V
• Reverse leakage current characteristics at rated voltage
• Single-phase bridge rectifier topology

Mechanical Parameters:

• Surface mount mounting type
• 4-SMD, Gull Wing package configuration
• Operating temperature range of -55°C to 150°C

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level 1 (unlimited shelf life)
• REACH unaffected status

The identified substitute parts DF15005S-E3/77 and DF005S maintain electrical equivalence within the specified parameter tolerances and share identical mechanical packaging requirements. Both parts are classified as single-phase standard technology bridge rectifiers with surface mount gull wing configuration.

Engineering Selection Recommendations

DF15005S-E3/77 (Vishay General Semiconductor - Diodes Division)

This substitute maintains active product status and provides direct electrical equivalence to the DBLS151GHRDG. The DF15005S-E3/77 is specified with forward voltage of 1.1 V at 1.5 A, matching the main part specification exactly. Reverse leakage current is specified at 5 µA, which is within acceptable tolerance for standard bridge rectifier applications. The part is supplied in Tape & Reel packaging with 2839 units in stock. This option is suitable for new designs and ongoing production requiring automotive-grade reliability.

DF005S (onsemi)

This substitute provides electrical equivalence with identical voltage and current ratings. The DF005S is specified with forward voltage of 1.1 V at 1 A, which differs from the main part specification of 1.1 V at 1.5 A. Reverse leakage current is specified at 5 µA. The part carries a "Not For New Designs" product status designation, indicating it is maintained for legacy applications and existing designs only. The DF005S is supplied in Cut Tape and Digi-Reel packaging with 2632 units in stock. This option is appropriate for sustaining production of established products.

Frequently Asked Questions (FAQ)

Q: What determines whether a bridge rectifier can substitute for the DBLS151GHRDG?

A: Substitution requires equivalence across peak reverse voltage (50 V), average rectified current (1.5 A), forward voltage characteristics (1.1 V maximum), operating temperature range (-55°C to 150°C), and package configuration (4-SMD, Gull Wing surface mount). All substitute parts must maintain RoHS3 compliance and MSL 1 rating.

Q: Are the DF15005S-E3/77 and DF005S interchangeable with the DBLS151GHRDG?

A: Both parts meet the core electrical and mechanical requirements for substitution. The DF15005S-E3/77 maintains active product status and is suitable for new designs. The DF005S carries a "Not For New Designs" designation and is appropriate for legacy applications only.

Q: What is the difference in reverse leakage current between the main part and substitutes?

A: The DBLS151GHRDG specifies 2 µA reverse leakage at 50 V. Both substitute parts specify 5 µA at 50 V. This difference remains within acceptable operating parameters for standard bridge rectifier applications.

Q: Does the forward voltage specification differ between the main part and DF005S?

A: The DBLS151GHRDG and DF15005S-E3/77 both specify 1.1 V forward voltage at 1.5 A. The DF005S specifies 1.1 V at 1 A, which represents a different measurement condition but maintains the same maximum voltage rating.

Q: What packaging formats are available for these substitute parts?

A: The DF15005S-E3/77 is supplied in Tape & Reel format. The DF005S is supplied in Cut Tape and Digi-Reel packaging. The main part DBLS151GHRDG uses the DBLS supplier device package. All three parts share identical 4-SMD, Gull Wing case configuration for PCB assembly compatibility.

Q: Are all three parts compliant with automotive and environmental standards?

A: The DBLS151GHRDG carries AEC-Q101 automotive qualification. All three parts are RoHS3 compliant, REACH unaffected, and rated MSL 1 (unlimited moisture sensitivity). The DF15005S-E3/77 maintains active status for automotive applications. The DF005S is suitable for legacy automotive designs.

Q: What inventory levels are available for each part?

A: DBLS151GHRDG: 1087 units in stock. DF15005S-E3/77: 2839 units in stock. DF005S: 2632 units in stock.
