DB151L-BP Bridge Rectifier Single Phase 50V 1.5A Equivalent & Substitute Parts

Part Overview

The DB151L-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, designed for through-hole mounting applications requiring 50V peak reverse voltage and 1.5A average rectified current. This component operates across an extended temperature range of -55°C to 150°C and utilizes standard rectifier technology in a 4-EDIP package configuration.

The DB151L-BP carries a "Not For New Designs" product status, indicating that this part is no longer recommended for new circuit development. This status necessitates identification of active equivalent alternatives that maintain identical or superior electrical and mechanical specifications to ensure design continuity and long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the DB151L-BP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Peak Reverse (Max): 50V
• Current - Average Rectified (Io): 1.5A
• Voltage - Forward (Vf) (Max) @ If: 1.1V @ 1.5A
• Operating Temperature Range: -55°C to 150°C
• Mounting Type: Through Hole
• Package / Case: 4-EDIP (0.321", 8.15mm)
• Diode Type: Single Phase
• Technology: Standard

The DB151G manufactured by GeneSiC Semiconductor satisfies all mandatory matching parameters and qualifies as a parametric equivalent. The DB151G maintains identical electrical performance specifications while offering improved reverse leakage characteristics (5µA versus 10µA at 50V) and carries an Active product status with RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The DB151G represents the appropriate substitute for the DB151L-BP in applications requiring continued component availability and design compliance with current regulatory standards.

Selection Basis:

The DB151G maintains complete electrical and mechanical compatibility with the DB151L-BP across all specified parameters. The substitute part carries an Active product status, ensuring long-term availability and manufacturing support. The DB151G additionally provides RoHS compliance certification and Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), meeting modern supply chain and environmental requirements.

The improved reverse leakage specification of the DB151G (5µA versus 10µA at 50V) represents a performance enhancement that does not introduce any compatibility concerns in existing circuit designs. The identical forward voltage drop, peak reverse voltage, and average rectified current ensure direct functional equivalence in all application contexts.

For designs currently utilizing the DB151L-BP, transition to the DB151G is supported by identical package geometry, pinout configuration, and thermal operating range. No circuit modifications are required.

Frequently Asked Questions (FAQ)

Q: Can the DB151G directly replace the DB151L-BP without circuit modifications?

A: Yes. The DB151G maintains identical electrical specifications for voltage, current, and temperature range, and shares the same 4-EDIP through-hole package configuration. Direct substitution is supported without circuit redesign.

Q: What is the significance of the "Not For New Designs" status on the DB151L-BP?

A: This designation indicates that Micro Commercial Co no longer recommends the DB151L-BP for new circuit development. Existing designs may continue to use available inventory, but new applications should specify the DB151G or equivalent active alternatives to ensure long-term supply chain continuity.

Q: How does the reverse leakage difference between DB151L-BP (10µA) and DB151G (5µA) affect circuit performance?

A: The lower reverse leakage of the DB151G represents improved performance characteristics. In most applications, this difference does not impact circuit functionality. Applications with specific leakage requirements should verify that the 5µA specification meets design criteria.

Q: Are the package dimensions identical between DB151L-BP and DB151G?

A: Yes. Both parts utilize the 4-EDIP package with dimensions of 0.321" (8.15mm). PCB footprints and mounting hole patterns are identical, supporting direct mechanical substitution.

Q: What compliance certifications does the DB151G provide?

A: The DB151G carries RoHS compliance certification and an MSL rating of 1 (Unlimited), indicating unrestricted moisture sensitivity handling. The DB151L-BP compliance status is not specified in available documentation.

Q: Is the DB151G available in equivalent quantities to the DB151L-BP?

A: Current inventory status indicates 803 pieces of DB151G available as new original stock, compared to 1095 pieces of DB151L-BP. Availability should be confirmed with the component supplier for specific procurement requirements.
