MBR2020CT-BP Equivalent & Substitute Parts

Part Overview

The MBR2020CT-BP is a Schottky diode array manufactured by Micro Commercial Co, configured as a 1 Pair Common Cathode arrangement with a maximum reverse voltage rating of 20 V and average rectified current of 20 A per diode. The device is packaged in a TO-220-3 through-hole format and features fast recovery characteristics suitable for high-frequency rectification applications.

This part is classified as Obsolete. Identification of equivalent and substitute components is necessary to support ongoing maintenance, repair, and new design requirements where the original part is no longer available from standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR2020CT-BP is determined by the following criteria:

Mandatory Compatibility Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Mounting Type: Through Hole
• Package / Case: TO-220-3
• Supplier Device Package: TO-220AB

Allowable Parameter Variations:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 20 V
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 20 A
• Operating Temperature - Junction: Equal to or greater than the specified range
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

The MBR2040CT-BP qualifies as a substitute because it maintains identical diode configuration, technology, mounting type, and package specifications while providing an elevated reverse voltage rating of 40 V. The current rating and thermal operating range remain unchanged, and the fast recovery speed specification is preserved.

Engineering Selection Recommendations

The MBR2040CT-BP is the designated substitute for the MBR2020CT-BP based on the following engineering criteria:

Product Status: The MBR2040CT-BP carries an Active product status, ensuring continued availability and supply chain support. The original MBR2020CT-BP is classified as Obsolete, making the substitute necessary for ongoing component procurement.

Compliance and Certifications: Both parts maintain identical REACH Status (REACH Unaffected), ECCN (EAR99), and HTSUS (8541.10.0080) classifications, ensuring regulatory equivalence for export and supply chain purposes.

Electrical Compatibility: The substitute maintains all critical electrical parameters including current rating, speed characteristics, and thermal operating range. The increased reverse voltage rating of 40 V provides enhanced voltage margin in applications originally designed for 20 V operation, with no adverse impact on circuit performance.

Physical Compatibility: Identical TO-220-3 package specifications and through-hole mounting type ensure direct mechanical and electrical interchangeability without PCB redesign or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can the MBR2040CT-BP be used as a direct replacement for the MBR2020CT-BP?

A: Yes. The MBR2040CT-BP is electrically and mechanically compatible with the MBR2020CT-BP. Both devices share identical diode configuration, package type, current rating, and thermal specifications. The higher reverse voltage rating of the substitute does not create compatibility issues in applications designed for 20 V operation.

Q: What is the primary difference between these two parts?

A: The maximum reverse voltage rating differs. The MBR2020CT-BP is rated for 20 V, while the MBR2040CT-BP is rated for 40 V. All other electrical and mechanical parameters remain identical.

Q: Are there any circuit design considerations when substituting the MBR2040CT-BP for the MBR2020CT-BP?

A: No design modifications are required. The substitute part operates within the same current, temperature, and speed parameters as the original. The elevated voltage rating provides additional safety margin without affecting circuit operation.

Q: What is the package compatibility between these parts?

A: Both parts use the TO-220-3 package with TO-220AB supplier device package designation. They are physically identical and mount identically on through-hole PCBs.

Q: Why is the MBR2020CT-BP classified as Obsolete?

A: The MBR2020CT-BP has reached end-of-life status and is no longer manufactured. The MBR2040CT-BP remains in active production and serves as the current equivalent offering from Micro Commercial Co.

Q: Are the reverse leakage current specifications equivalent?

A: The reverse leakage current is specified at the respective maximum voltage ratings. The MBR2020CT-BP specifies 100 µA @ 20 V, while the MBR2040CT-BP specifies 100 µA @ 40 V. This represents equivalent leakage performance at each device's rated voltage.
