DB203L-BP Bridge Rectifier Single Phase Standard 200 V Through Hole

Part Overview

The DB203L-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, designed for interface applications requiring 200 V peak reverse voltage rating. This component features a 4-EDIP through-hole package (DBL-1) with 2 A average rectified current capacity. The DB203L-BP is classified as obsolete, necessitating identification of active substitute components for new designs and ongoing production requirements. Equivalent parts must maintain functional compatibility across electrical and mechanical parameters while offering current product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB203L-BP is determined by strict equivalence across the following critical parameters:

Mandatory Compatibility Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
• Current - Reverse Leakage: 10 µA
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: 4-EDIP (0.321", 8.15mm)
• Supplier Device Package: DBL-1

Voltage Rating Consideration: The DB203L-BP specifies 200 V peak reverse voltage. Substitute components may exceed this voltage rating while maintaining all other electrical and mechanical parameters. Higher voltage-rated components operate within the same thermal and current specifications and are electrically compatible in applications designed for 200 V operation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The DB203L-BP is classified as obsolete. The DB207L-BP is an active product from the same manufacturer, ensuring continued availability and supply chain reliability for new designs and production continuity.

Compliance and Certification: Both the DB203L-BP and DB207L-BP maintain identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.10.0080), confirming regulatory equivalence for export and compliance purposes.

Electrical and Mechanical Compatibility: The DB207L-BP maintains all critical electrical parameters: 2 A average rectified current, 1.1 V forward voltage at 2 A, and identical operating temperature range (-55°C to 150°C). The 4-EDIP through-hole package (DBL-1) is mechanically identical, enabling direct board-level substitution without layout modifications.

Voltage Rating: The DB207L-BP features a 1 kV peak reverse voltage rating, exceeding the DB203L-BP specification of 200 V. This higher rating provides additional design margin and does not compromise performance in applications specified for 200 V operation.

Frequently Asked Questions (FAQ)

Q: Can the DB207L-BP directly replace the DB203L-BP in existing designs?

A: Yes. The DB207L-BP is electrically and mechanically compatible with the DB203L-BP. Both components share identical current ratings (2 A), forward voltage characteristics (1.1 V @ 2 A), operating temperature range (-55°C to 150°C), and package configuration (4-EDIP DBL-1 through-hole). The higher voltage rating of the DB207L-BP (1 kV vs. 200 V) does not prevent substitution in 200 V applications.

Q: What is the significance of the higher voltage rating on the DB207L-BP?

A: The DB207L-BP's 1 kV peak reverse voltage rating exceeds the DB203L-BP's 200 V specification. In applications designed for 200 V operation, the higher-rated component operates within its safe operating area and provides additional voltage margin. This does not alter the component's performance at lower voltages.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the DB203L-BP and DB207L-BP use the 4-EDIP package with dimensions of 0.321" (8.15mm). The supplier device package designation (DBL-1) is identical for both components, confirming mechanical interchangeability without PCB layout changes.

Q: What compliance certifications apply to both parts?

A: Both components maintain REACH Unaffected status, EAR99 ECCN classification, and HTSUS code 8541.10.0080. These certifications are identical, confirming regulatory equivalence for procurement and export compliance.

Q: Why is the DB203L-BP classified as obsolete?

A: The DB203L-BP is no longer in active production. The DB207L-BP serves as the active equivalent from Micro Commercial Co, ensuring continued product availability and supply chain support for new designs and ongoing manufacturing requirements.
