DB153G Bridge Rectifier Single Phase 200V 1.5A Equivalent & Substitute Parts

Part Overview

The DB153G is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 200V peak reverse voltage and 1.5A average rectified current. This component is classified as Active product status and is RoHS Compliant. Bridge rectifiers in this voltage and current class are used in AC-to-DC conversion applications requiring through-hole mounting in 4-EDIP package configuration. Substitute parts may be required due to inventory availability, manufacturing discontinuation, or design revision requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DB153G is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Peak Reverse (Max): 200V
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 150°C

Allowable Variation Parameters:

• Current - Average Rectified (Io): Substitute must equal or exceed 1.5A
• Voltage - Forward (Vf): Substitute must not exceed 1.1V at rated current
• Current - Reverse Leakage: Substitute must not exceed 5µA at 200V
• Package / Case: 4-EDIP configuration with compatible pin spacing (0.300" to 0.321")

The DB153G has two identified substitute parts: DB103-BP and DF02M. Both maintain the 200V peak reverse voltage and single-phase bridge rectifier topology. Variations in current rating, forward voltage characteristics, and package dimensions are within acceptable engineering tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

DB153G (Primary Component): The DB153G maintains Active product status and is RoHS Compliant. This part is suitable for new designs and ongoing production. Current inventory of 932 pieces supports immediate availability.

DB103-BP (Substitute - Current Derating Required): The DB103-BP is rated for 1.0A average rectified current, which is 33% lower than the DB153G specification of 1.5A. This substitute is classified as Not For New Designs. Selection of DB103-BP requires circuit-level verification that application current demand does not exceed 1.0A. Reverse leakage current is elevated to 10µA compared to 5µA for the primary part. ROHS3 compliance is maintained. Packaging is identical (4-EDIP 0.321", 8.15mm).

DF02M (Substitute - Obsolete Status): The DF02M is classified as Obsolete and should not be selected for new designs or long-term production. Current rating matches the DB153G at 1.5A, and reverse leakage is equivalent at 5µA. Package dimensions differ slightly (0.300" vs 0.321"), which may require PCB layout verification. ROHS3 compliance is maintained. Inventory availability is 2100 pieces.

Compliance Considerations: All three parts maintain RoHS compliance status. The DB153G and DF02M both achieve ROHS3 classification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for DB153G and DB103-BP, indicating no special moisture handling requirements.

Frequently Asked Questions (FAQ)

Q: Can DB103-BP be used as a direct replacement for DB153G?

A: DB103-BP is mechanically compatible (identical 4-EDIP 0.321" package) and electrically compatible at the 200V voltage rating. However, the current rating is reduced from 1.5A to 1.0A. Direct substitution is only valid if circuit current requirements do not exceed 1.0A. Reverse leakage current increases from 5µA to 10µA, which may affect circuit performance in sensitive applications.

Q: What is the significance of the "Not For New Designs" status on DB103-BP?

A: This designation indicates the manufacturer has discontinued active support for new product development. While the part may remain available from inventory, it is not recommended for designs entering production or requiring long-term supply assurance.

Q: Is DF02M suitable for production use?

A: DF02M is classified as Obsolete and should not be selected for production applications. Obsolete parts carry risk of supply discontinuation and lack of manufacturer support. This part is listed as a historical equivalent only.

Q: Are there package compatibility concerns between DB153G and DF02M?

A: Both parts use 4-EDIP configuration, but pin spacing differs: DB153G is 0.321" (8.15mm) while DF02M is 0.300" (7.62mm). PCB layout verification is required before substitution to confirm through-hole spacing compatibility.

Q: What is the impact of higher reverse leakage current in DB103-BP?

A: DB103-BP specifies 10µA reverse leakage at 200V, compared to 5µA for DB153G. This doubling of leakage current may affect circuit performance in applications with high impedance paths or sensitive analog circuits. Circuit-level analysis is required to determine acceptability.

Q: Are all three parts RoHS compliant?

A: Yes. DB153G is RoHS Compliant. DB103-BP and DF02M are both ROHS3 Compliant, which represents a more recent compliance standard. All three parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the operating temperature range for these parts?

A: All three parts operate across the identical temperature range of -55°C to 150°C (junction temperature). No thermal performance differences exist between the primary part and substitutes.
