DBLS151G RDG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBLS151G RDG 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 component operates across the temperature range of -55°C to 150°C and is packaged in a 4-SMD, Gull Wing surface mount configuration. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility. Alternative components serve applications where the original part number is unavailable, where supply chain optimization is required, or where design flexibility permits component interchange within the specified parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBLS151G RDG are qualified based on the following criteria:

Electrical Parameter Matching:

• Peak reverse voltage rating of 50 V
• Average rectified current rating of 1.5 A
• Forward voltage drop (Vf) of 1.1 V maximum
• Reverse leakage current within specified limits
• Single-phase bridge rectifier topology
• Standard rectifier technology

Mechanical & Environmental Compatibility:

• Surface mount mounting type
• 4-SMD, Gull Wing package configuration
• Operating temperature range of -55°C to 150°C
• RoHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity level

Regulatory & Compliance Alignment:

• REACH Unaffected status
• ECCN EAR99 classification
• HTSUS 8541.10.0080 tariff code

Substitute parts must satisfy all electrical parameters within the specified tolerances and maintain identical mechanical packaging to ensure direct board-level compatibility without design modification.

Engineering Selection Recommendations

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

This substitute part maintains Active product status and is recommended for new designs and ongoing production applications. The DF15005S-E3/77 matches all critical electrical parameters with the DBLS151G RDG, including peak reverse voltage, average rectified current, and forward voltage characteristics. The component is supplied in Tape & Reel (TR) packaging format and carries full RoHS3 compliance and REACH Unaffected status. Reverse leakage current specification of 5 µA at 50 V is within acceptable tolerance relative to the main part.

DF005S (onsemi)

This substitute part carries a Not For New Designs product status designation. While the DF005S meets all core electrical specifications for peak reverse voltage, average rectified current, and operating temperature range, its discontinued design status restricts application to legacy system support and maintenance scenarios. The forward voltage specification is rated at 1.1 V maximum at 1 A (versus 1.5 A for the main part), representing a minor specification variance. This component is available in Cut Tape (CT) & Digi-Reel® packaging and maintains full RoHS3 compliance.

Selection between substitute parts should prioritize DF15005S-E3/77 for applications requiring long-term supply assurance and design continuity. The DF005S is suitable only where existing inventory supports legacy product maintenance or where design constraints permit use of a non-recommended component.

Frequently Asked Questions (FAQ)

Q: Can the DF15005S-E3/77 be used as a direct replacement for the DBLS151G RDG on existing circuit boards?

A: Yes. Both components share identical electrical ratings (50 V peak reverse voltage, 1.5 A average rectified current, 1.1 V forward voltage at 1.5 A) and are packaged in 4-SMD, Gull Wing surface mount configuration. No circuit design modification is required for substitution.

Q: What is the significance of the DF005S being marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life status and is not recommended for incorporation into new product designs. The DF005S remains suitable for maintenance and repair of existing systems where supply from original inventory is available. New designs should specify the DF15005S-E3/77 or DBLS151G RDG to ensure long-term component availability.

Q: Are there differences in reverse leakage current between the main part and substitutes?

A: The DBLS151G RDG specifies 2 µA maximum reverse leakage at 50 V. Both substitute parts (DF15005S-E3/77 and DF005S) specify 5 µA maximum at 50 V. This variance remains within acceptable engineering tolerance for standard bridge rectifier applications and does not affect functional compatibility.

Q: Does the packaging format difference between Tape & Reel and Cut Tape affect component selection?

A: Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) affects supply chain logistics and assembly line handling but does not impact electrical or mechanical compatibility. The physical component dimensions and pin configuration remain identical across all three parts.

Q: Are all three parts RoHS3 compliant?

A: Yes. The DBLS151G RDG, DF15005S-E3/77, and DF005S all carry RoHS3 Compliant status and are REACH Unaffected. All three components meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the forward voltage specification difference noted for the DF005S?

A: The DF005S specifies forward voltage of 1.1 V maximum at 1 A, while the main part and DF15005S-E3/77 specify 1.1 V maximum at 1.5 A. This represents a measurement condition difference rather than a functional incompatibility. At the rated 1.5 A operating current, the DF005S forward voltage remains within acceptable circuit performance parameters.
