MBR2050CT-G Equivalent & Substitute Parts

Part Overview

The MBR2050CT-G is a Schottky diode array manufactured by Comchip Technology, configured as 1 pair common cathode with 50 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 currently in active product status with 901 pieces in stock.

Substitute parts are necessary when the MBR2050CT-G becomes unavailable from the primary manufacturer, when alternative packaging or thermal characteristics are required for specific applications, or when design requirements allow operation within the electrical and mechanical parameters of equivalent devices.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBR2050CT-G is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (pin-compatible requirement)
• Technology: Schottky (functional requirement)
• Mounting Type: Through Hole (mechanical requirement)
• Package / Case: TO-220-3 (physical requirement)

Electrical Operating Range Parameters:

• Voltage - DC Reverse (Vr) (Max): Must be ≥ 50 V
• Current - Average Rectified (Io) (per Diode): Must be ≥ 20 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected or REACH Affected (both acceptable for substitution)

Substitute parts meeting all mandatory criteria and electrical operating range parameters are functionally equivalent for direct replacement in applications designed for the MBR2050CT-G.

Parameter Comparison

Engineering Selection Recommendations

MBR2545CTG (onsemi): This substitute is rated for 45 V reverse voltage and 15 A average rectified current per diode. The device is active in production status with 15,312 pieces in stock. The lower current rating (15 A versus 20 A) and lower reverse voltage rating (45 V versus 50 V) restrict its use to applications where the circuit design operates within these reduced electrical parameters. The forward voltage drop is lower (620 mV @ 15 A) compared to the main part. Operating temperature range extends to 175 °C maximum junction temperature. ROHS3 compliance is confirmed.

MBR2550CT (Diodes Incorporated): This substitute is rated for 50 V reverse voltage and 15 A average rectified current per diode, matching the voltage specification of the main part but with reduced current capacity. The device is obsolete in product status with 3,150 pieces in stock. The lower current rating (15 A versus 20 A) restricts its use to applications where circuit design operates within this reduced electrical parameter. The forward voltage drop is 750 mV @ 15 A. Operating temperature range is -65 to 150 °C. ROHS3 compliance is confirmed. REACH status is listed as affected.

Selection between substitute parts depends on application requirements for reverse voltage and average rectified current. Both substitutes are pin-compatible and mechanically equivalent in TO-220-3 packaging. Applications requiring the full 20 A current rating of the main part cannot use either substitute without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can MBR2545CTG replace MBR2050CT-G in all applications?

A: MBR2545CTG is pin-compatible and mechanically equivalent in TO-220-3 packaging. However, it is rated for 45 V reverse voltage and 15 A average rectified current per diode, compared to 50 V and 20 A for the MBR2050CT-G. Substitution is valid only in applications where the circuit design operates within the reduced electrical parameters of the MBR2545CTG.

Q: What is the difference between MBR2550CT and MBR2050CT-G?

A: Both devices are rated for 50 V reverse voltage and use TO-220-3 packaging. The MBR2550CT is rated for 15 A average rectified current per diode, while the MBR2050CT-G is rated for 20 A. The MBR2550CT is obsolete in product status. Substitution is valid only in applications where the circuit design operates within the 15 A current rating.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MBR2545CTG and MBR2550CT are both ROHS3 compliant, matching the compliance status of the MBR2050CT-G.

Q: What is the impact of forward voltage differences between these parts?

A: Forward voltage drop affects power dissipation and thermal performance. MBR2545CTG has the lowest forward voltage (620 mV @ 15 A), while MBR2050CT-G has the highest (950 mV @ 20 A). Lower forward voltage reduces heat generation in the device. Forward voltage specifications are provided at different current levels and cannot be directly compared across different current ratings.

Q: Can I use MBR2550CT if the main part is unavailable?

A: MBR2550CT is pin-compatible and mechanically equivalent in TO-220-3 packaging. However, it is rated for 15 A average rectified current per diode versus 20 A for the MBR2050CT-G. Substitution is valid only in applications where the circuit design operates within the 15 A current rating. The device is obsolete in product status.

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

A: This configuration describes the internal diode arrangement within the package. All listed substitute parts have identical 1 Pair Common Cathode configuration, ensuring pin compatibility and functional equivalence at the circuit interface level.

Q: Are there temperature range differences that affect substitution?

A: MBR2545CTG operates from -65 to 175 °C junction temperature, while MBR2050CT-G operates from -55 to 150 °C. MBR2550CT operates from -65 to 150 °C. Extended temperature range in MBR2545CTG may provide additional margin in high-temperature applications, but substitution decisions must be based on application requirements and circuit design parameters.
