DB201-BP Bridge Rectifier Single Phase Standard 50 V Through Hole Equivalent & Substitute Parts

Part Overview

The DB201-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, designed for through-hole mounting applications requiring 50 V peak reverse voltage rating and 2 A average rectified current. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity. The DB201-BP operates across a wide temperature range of -55°C to 150°C (TJ) and is housed in a 4-EDIP (0.321", 8.15mm) package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB201-BP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

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

Voltage Rating Consideration: The DB201-BP operates at 50 V peak reverse voltage. Substitute parts must maintain electrical compatibility within the application circuit. The DB207-BP shares identical mechanical packaging, current rating, forward voltage characteristics, and temperature range, with an elevated voltage rating of 1 kV peak reverse voltage. This higher voltage rating does not compromise functionality in 50 V applications and provides enhanced overvoltage protection margin.

Parameter Comparison

Engineering Selection Recommendations

The DB207-BP is the designated manufacturer-recommended substitute for the obsolete DB201-BP. Both components are manufactured by Micro Commercial Co and share identical mechanical and thermal specifications. The DB207-BP maintains active product status, ensuring long-term availability and supply chain continuity.

Compliance and Regulatory Alignment: Both the DB201-BP and DB207-BP carry REACH Unaffected status and EAR99 ECCN classification, indicating equivalent regulatory compliance profiles. The HTSUS code 8541.10.0080 applies to both components.

Electrical Equivalence: The DB207-BP delivers identical forward voltage characteristics (1.1 V @ 2 A) and operating temperature range (-55°C ~ 150°C TJ) as the DB201-BP. The elevated peak reverse voltage rating (1 kV versus 50 V) does not introduce incompatibility in applications designed for 50 V operation and provides additional transient overvoltage protection.

Packaging and Mounting: Both components utilize the 4-EDIP (0.321", 8.15mm) through-hole package configuration, enabling direct mechanical and electrical substitution without PCB redesign or layout modification.

Frequently Asked Questions (FAQ)

Q: Can the DB207-BP directly replace the DB201-BP in existing designs?

A: Yes. The DB207-BP is the manufacturer-recommended substitute. Both components share identical package geometry (4-EDIP), current rating (2 A), forward voltage (1.1 V @ 2 A), and operating temperature range (-55°C ~ 150°C TJ). Pin-to-pin compatibility is maintained.

Q: What is the significance of the higher voltage rating on the DB207-BP?

A: The DB207-BP features a 1 kV peak reverse voltage rating compared to the DB201-BP's 50 V rating. In applications designed for 50 V operation, the higher rating provides enhanced protection against transient overvoltage events without affecting normal circuit operation.

Q: Are there any thermal or current handling differences between these parts?

A: No. Both components operate across the identical temperature range (-55°C ~ 150°C TJ) and handle the same average rectified current (2 A). Thermal performance characteristics are equivalent.

Q: Why is the DB201-BP classified as obsolete?

A: The DB201-BP has reached end-of-life status. The DB207-BP remains in active production, providing continued design support and procurement availability for applications requiring single-phase bridge rectifier functionality in this package class.

Q: Are regulatory certifications equivalent between the two parts?

A: Yes. Both the DB201-BP and DB207-BP carry identical REACH Unaffected status, EAR99 ECCN classification, and HTSUS code 8541.10.0080, indicating equivalent regulatory compliance.

Q: What packaging options are available for the DB207-BP?

A: The DB207-BP is supplied in Bulk packaging, whereas the DB201-BP was supplied without specified packaging designation. Both utilize the 4-EDIP (0.321", 8.15mm) through-hole package configuration.
