MBR20100CT-G Equivalent & Substitute Parts Reference

Part Overview

The MBR20100CT-G is a Schottky diode array manufactured by Comchip Technology, configured as 1 pair common cathode with 100 V reverse voltage rating and 20 A average rectified current per diode. The device is packaged in TO-220-3 through-hole configuration and is classified as obsolete product status.

Due to the obsolete status of the MBR20100CT-G, equivalent and substitute parts are necessary for ongoing design support, production continuity, and component sourcing. Substitute parts maintain the same electrical and mechanical parameters within specified tolerances while offering active product status or improved availability.

Substitute Part Grouping Explanation

Substitution of the MBR20100CT-G is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

Diode Configuration: 1 Pair Common Cathode (mandatory match)
Technology: Schottky (mandatory match)
Voltage - DC Reverse (Vr) (Max): 100 V (mandatory match)
Mounting Type: Through Hole (mandatory match)
Package / Case: TO-220-3 (mandatory match for direct pin-compatible substitution)

Allowable Parameter Variations:

Current - Average Rectified (Io): Substitute parts may have equal or greater current rating
Voltage - Forward (Vf): Substitute parts may have equal or lower forward voltage
Current - Reverse Leakage: Substitute parts may have equal or lower leakage current
Operating Temperature - Junction: Substitute parts may have equal or extended temperature range
Product Status: Active status preferred over obsolete

Substitute parts are grouped into two categories:

Category 1: MFR Recommended Substitutes — Parts meeting all critical parameters with active product status or improved electrical characteristics.

Category 2: Parametric Equivalents — Parts meeting all critical parameters with alternative package configurations or automotive qualification.

Engineering Selection Recommendations

Direct Pin-Compatible Substitutes (TO-220-3 Package):

MBR20H100CT (Taiwan Semiconductor Corporation) is the primary direct substitute. This part maintains identical electrical specifications to the MBR20100CT-G with 20 A current rating, 100 V reverse voltage, and 950 mV forward voltage. The MBR20H100CT offers active product status and extended maximum junction temperature to 175°C. RoHS3 compliance and REACH unaffected status are maintained.

STPS60H100CT (STMicroelectronics) provides a higher current rating option at 30 A with improved reverse leakage characteristics (10 µA versus 100 µA). This part is suitable for applications requiring additional current margin. Active product status and extended temperature range to 175°C are provided.

STPS20100CT (STMicroelectronics) offers active product status with identical forward voltage specification. Current rating is reduced to 10 A, making this suitable only for applications with lower current requirements.

Alternative Package Substitute (TO-247-3 Package):

MBR20100PTHC0G (Taiwan Semiconductor Corporation) maintains all electrical parameters of the MBR20100CT-G while providing TO-247-3 package configuration. This part includes AEC-Q101 automotive qualification and active product status. Physical package dimensions differ; PCB layout modification is required.

Compliance and Certification:

All recommended substitutes maintain RoHS3 compliance and REACH unaffected status. The MBR20100PTHC0G includes AEC-Q101 automotive qualification for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can MPE-220A be used as a direct replacement for MBR20100CT-G?

A: MPE-220A is not a direct replacement. While it maintains the same 100 V reverse voltage, diode configuration, and TO-220-3 package, the current rating is reduced to 10 A compared to the 20 A specification of MBR20100CT-G. Use MPE-220A only in applications where 10 A current per diode is sufficient.

Q: What is the difference between MBR20H100CT and MBR20100CT?

A: MBR20H100CT (Taiwan Semiconductor Corporation) and MBR20100CT (Good-Ark Semiconductor) are distinct parts. MBR20H100CT maintains the full 20 A current rating with active product status. MBR20100CT has a reduced 10 A current rating. For applications requiring 20 A operation, MBR20H100CT is the appropriate choice.

Q: Is MBR20100PTHC0G compatible with existing PCB layouts designed for MBR20100CT-G?

A: MBR20100PTHC0G uses TO-247-3 package while MBR20100CT-G uses TO-220-3 package. Physical dimensions and pin spacing differ. PCB layout modification is required for this substitution. Direct socket compatibility does not exist.

Q: Can STPS60H100CT be used in place of MBR20100CT-G?

A: STPS60H100CT maintains the same 100 V reverse voltage, Schottky technology, 1 pair common cathode configuration, and TO-220-3 package. The 30 A current rating exceeds the 20 A requirement. This part is electrically compatible and provides improved reverse leakage performance (10 µA versus 100 µA). STPS60H100CT is suitable for direct substitution with enhanced current capability.

Q: What compliance certifications are maintained across substitute parts?

A: All recommended substitute parts maintain RoHS3 compliance and REACH unaffected status. MBR20100PTHC0G additionally includes AEC-Q101 automotive qualification. Moisture Sensitivity Level (MSL) 1 (Unlimited) is maintained across all substitutes.

Q: Why is the MBR20100CT-G classified as obsolete?

A: Product status is provided as specified in manufacturer data. Obsolete classification indicates the part is no longer in active production. Active substitute parts are recommended for new designs and ongoing production requirements.
