Substitute Part Grouping Explanation

Substitution of the MBR2060CT is determined by the following critical parameters:

Primary Substitution Criteria:

Diode Configuration: 1 Pair Common Cathode (mandatory)
Technology: Schottky (mandatory)
Voltage - DC Reverse (Vr) (Max): 60 V (mandatory)
Mounting Type: Through Hole (mandatory)
Package / Case: TO-220-3 (mandatory)

Secondary Compatibility Parameters:

Current - Average Rectified (Io) (per Diode): 10 A or higher
Voltage - Forward (Vf) (Max) @ If: Must not exceed application requirements
Current - Reverse Leakage @ Vr: Lower values preferred for reduced power dissipation
Operating Temperature - Junction: Must encompass application operating range
RoHS Status: ROHS3 Compliant (mandatory for regulated applications)

Substitute parts are grouped into two categories:

Category 1 - Direct Current Rating Match (10 A): Parts with identical 10 A current rating maintain exact electrical equivalence with the MBR2060CT.

Category 2 - Higher Current Rating (15 A or 20 A): Parts with higher current ratings provide enhanced current handling capability while maintaining all other critical parameters. These parts are electrically compatible and provide design margin for applications requiring higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can MBR2060CT be replaced with a higher current-rated part such as STPS30H60CT (15 A)?

A: Yes. The STPS30H60CT maintains all critical parameters: 60 V reverse voltage, 1 Pair Common Cathode configuration, TO-220-3 package, and fast recovery Schottky technology. The higher 15 A current rating provides design margin and does not compromise compatibility. The application circuit must accommodate the lower forward voltage (660 mV @ 15 A versus 800 mV @ 10 A).

Q: What is the difference between MBR2060CTG and MBR2060CT?

A: Both parts are 10 A Schottky diode arrays with 60 V reverse voltage in TO-220-3 packages. MBR2060CTG is manufactured by onsemi and features an extended junction temperature range (-65°C to 175°C) compared to the Littelfuse MBR2060CT (-55°C to 150°C). Forward voltage is slightly higher at 850 mV @ 10 A. MBR2060CTG is currently active in production.

Q: Are STPS20L60CT and MBR2060CT electrically interchangeable?

A: Yes. Both parts are 10 A Schottky diode arrays with 60 V reverse voltage, 1 Pair Common Cathode configuration, and TO-220-3 packages. STPS20L60CT offers superior forward voltage performance (600 mV @ 10 A versus 800 mV @ 10 A), resulting in lower power dissipation. Both parts are currently in active production.

Q: Why are some substitute parts listed as obsolete?

A: Obsolete parts are included in this reference for legacy system support and repair applications where original specifications must be maintained. For new product designs, active status parts are strongly preferred to ensure long-term supply chain availability and manufacturing consistency.

Q: Can MBR2060CT be used in applications designed for 20 A parts such as STPS40M60CT?

A: No. The MBR2060CT is rated for 10 A average rectified current per diode. Using it in a 20 A application would exceed its current rating and result in thermal stress, reduced reliability, and potential device failure. The application must be designed for the specific current rating of the selected part.

Q: What is the significance of forward voltage differences between substitute parts?

A: Forward voltage directly affects power dissipation in the diode. Lower forward voltage (such as STPS20L60CT at 600 mV @ 10 A) results in reduced heat generation and improved efficiency. Higher forward voltage (such as MBR2060CT at 800 mV @ 10 A) increases power dissipation. Selection depends on thermal design requirements and efficiency targets of the application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and are suitable for applications subject to RoHS regulations.

Q: What does "1 Pair Common Cathode" configuration mean?

A: This configuration contains two diodes with a shared cathode terminal. The common cathode connection is brought out as a single pin, while the two anodes are separate pins. This configuration is standard for bridge rectifier applications and dual-diode circuits. All substitute parts maintain this identical configuration.

Q: Can STPS30H60CT (15 A) be used as a direct replacement for MBR2060CT (10 A) in existing designs?

A: Yes, provided the application circuit can accommodate the different forward voltage characteristics. STPS30H60CT operates at 660 mV @ 15 A compared to MBR2060CT at 800 mV @ 10 A. The lower forward voltage may affect voltage regulation or bias point calculations in precision circuits. Verification of circuit performance is necessary for applications with tight voltage tolerance requirements.

Q: What is the difference between TO-220 and TO-220-3 package designations?

A: TO-220-3 specifies a three-pin through-hole package in the TO-220 form factor. All parts in this reference use TO-220-3 packages and are mechanically and electrically compatible for PCB mounting and thermal management.
