DB153-BP Bridge Rectifier Single Phase 200V 1.5A Equivalent & Substitute Parts

Part Overview

The DB153-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 200V peak reverse voltage and 1.5A average rectified current. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. The through-hole DB-1 package configuration and standard rectifier technology make it suitable for legacy applications requiring direct replacement or functional equivalence. Identifying qualified substitute parts is essential for maintaining supply continuity and supporting existing product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DB153-BP is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 1.5 A
• Mounting Type: Through Hole
• Package / Case: 4-EDIP (0.321", 8.15mm)
• Operating Temperature Range: -55°C to 150°C (TJ)

Performance Parameters (Equal or Better):

• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A or lower
• Current - Reverse Leakage @ Vr: 10 µA @ 200 V or lower

The DB153G manufactured by GeneSiC Semiconductor meets all mandatory matching parameters and demonstrates equivalent or superior performance characteristics. The reverse leakage current of 5 µA @ 200 V is lower than the DB153-BP specification, indicating improved performance within the same electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

DB153G Selection Basis:

The DB153G qualifies as a direct parametric equivalent to the DB153-BP based on matching electrical ratings and mechanical specifications. The DB153-BP carries "Not For New Designs" status, making the DB153G an appropriate alternative for ongoing production support.

The DB153G holds "Active" product status, ensuring continued availability and manufacturer support. The component is RoHS Compliant and carries Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating superior environmental compliance and handling flexibility compared to legacy alternatives.

Both components share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, confirming regulatory equivalence for export and tariff purposes.

The DB153G demonstrates improved reverse leakage performance (5 µA versus 10 µA @ 200 V), which reduces standby power dissipation and enhances circuit reliability in applications sensitive to leakage current.

Frequently Asked Questions (FAQ)

Q: Can DB153G replace DB153-BP in existing designs without PCB modification?

A: Yes. Both components use identical 4-EDIP (0.321", 8.15mm) through-hole packages with matching pin configurations. Direct socket substitution is possible without PCB layout changes.

Q: What is the significance of the "Not For New Designs" status on DB153-BP?

A: This designation indicates the DB153-BP has reached end-of-life. Micro Commercial Co no longer recommends this part for new product development. The DB153G, with "Active" status, is the appropriate selection for ongoing applications.

Q: Are the electrical ratings identical between DB153-BP and DB153G?

A: Yes. Both components are rated for 200V peak reverse voltage, 1.5A average rectified current, and 1.1V forward voltage drop at 1.5A. Operating temperature ranges are identical (-55°C to 150°C TJ).

Q: Does the lower reverse leakage current in DB153G (5 µA vs. 10 µA) affect circuit design?

A: The DB153G's lower reverse leakage is a performance improvement that reduces standby power dissipation. No circuit redesign is required; the substitute performs equal or better in this parameter.

Q: Are there compliance or certification differences between these parts?

A: The DB153G is RoHS Compliant with MSL 1 (Unlimited), providing superior environmental compliance. Both parts share identical ECCN and HTSUS classifications. The DB153G offers better long-term supply chain and regulatory support.

Q: What inventory status should influence the selection decision?

A: DB153-BP has 684 units in stock; DB153G has 932 units. The DB153G's higher inventory level and active product status provide greater supply security for ongoing production requirements.
