MBR1020FCT-BP Equivalent & Substitute Parts

Part Overview

The MBR1020FCT-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 10 A per diode. The device is packaged in a TO-220-3 Isolated Tab through-hole configuration.

This part is classified as Obsolete. Identification of equivalent and substitute components is necessary to support ongoing system maintenance, repair, and new design implementations where the original specification remains functionally appropriate or where higher voltage ratings provide enhanced system reliability margins.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR1020FCT-BP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Current - Average Rectified (Io) per Diode: 10 A (minimum)
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Isolated Tab
• Operating Temperature Range: -50°C to 150°C (minimum)

Allowable Variation:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 20 V

The MBR1040FCT-BP qualifies as a direct substitute because it maintains identical diode configuration, technology, current rating, mounting type, package form, and operating temperature range. The increased reverse voltage rating of 40 V provides enhanced voltage margin while remaining functionally compatible with applications designed for the 20 V specification.

Parameter Comparison

Engineering Selection Recommendations

MBR1020FCT-BP (Original Part): Product status is Obsolete. This part remains available in inventory (968 Pcs) but is no longer in active production. Use is limited to replacement and repair applications where the original specification is required.

MBR1040FCT-BP (Substitute Part): Product status is Active. This part is in current production and available in inventory (826 Pcs). The MBR1040FCT-BP is the recommended substitute for new designs and ongoing system support. The doubled reverse voltage rating (40 V versus 20 V) provides increased design margin without compromising any other electrical or mechanical parameter. Both parts carry identical REACH and ECCN compliance status (REACH Unaffected, EAR99).

Frequently Asked Questions (FAQ)

Q: Can the MBR1040FCT-BP be used as a direct replacement for the MBR1020FCT-BP?

A: Yes. The MBR1040FCT-BP is a direct substitute. Both devices share identical diode configuration, Schottky technology, 10 A current rating, operating temperature range, and TO-220-3 Isolated Tab package. The higher reverse voltage rating of the MBR1040FCT-BP (40 V) is compatible with applications designed for 20 V operation.

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

A: The maximum reverse voltage rating differs. The MBR1020FCT-BP is rated for 20 V, while the MBR1040FCT-BP is rated for 40 V. All other electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the TO-220-3 Isolated Tab package with identical pinout and mechanical dimensions. Direct board-level substitution is possible without layout modification.

Q: Why is the MBR1020FCT-BP classified as Obsolete?

A: The MBR1020FCT-BP has been discontinued by the manufacturer. The MBR1040FCT-BP remains in active production and serves as the current equivalent for this product line.

Q: Are there compliance or certification differences?

A: No. Both parts carry identical REACH status (REACH Unaffected) and ECCN classification (EAR99). Compliance requirements are equivalent.

Q: Can the MBR1020FCT-BP be used in applications requiring higher voltage margins?

A: The MBR1020FCT-BP is rated for 20 V maximum reverse voltage. Applications requiring higher voltage margins should use the MBR1040FCT-BP, which provides a 40 V rating.
