Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR2050CTHC0G is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Diode Configuration: 1 Pair Common Cathode (pin-compatible topology)
• Technology: Schottky (fast recovery characteristics)
• Voltage - DC Reverse (Vr) (Max): 50 V (minimum required rating)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: TO-220-3 (physical form factor)

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 20 A
• Voltage - Forward (Vf) (Max) @ If: Equal to or less than 950 mV @ 20 A
• Current - Reverse Leakage @ Vr: Equal to or less than 100 µA @ 50 V
• Operating Temperature - Junction: Range must encompass -55°C to 150°C

The MBR2550CT meets the core substitution criteria with the following considerations: it maintains identical voltage rating (50 V), identical diode configuration (1 Pair Common Cathode), identical technology (Schottky), identical mounting type (Through Hole), and identical package (TO-220-3). However, the average rectified current per diode is 15 A, which is lower than the 20 A specification of the main part.

Parameter Comparison

Engineering Selection Recommendations

MBR2050CTHC0G (Primary Part): The MBR2050CTHC0G is the preferred selection for new designs and applications requiring 20 A average rectified current per diode. This part maintains Active product status, ensuring long-term availability and supply chain stability. The part is qualified to AEC-Q101 automotive standards and is ROHS3 compliant, meeting regulatory requirements for automotive and industrial applications.

MBR2550CT (Substitute Part): The MBR2550CT is electrically and mechanically compatible with the MBR2050CTHC0G for applications where the average rectified current requirement does not exceed 15 A per diode. This part carries Obsolete product status, indicating that it is no longer in active production. The MBR2550CT is ROHS3 compliant and maintains the same voltage rating, diode configuration, and package form factor as the main part. The reverse leakage current is higher (1 mA @ 50 V versus 100 µA @ 50 V), which may impact thermal performance in low-leakage-critical applications. The operating temperature range extends to -65°C, providing broader low-temperature capability than the main part.

Selection of the MBR2550CT is appropriate only when the 15 A current rating satisfies circuit requirements and when supply of the primary part is constrained. The Obsolete status of the MBR2550CT indicates that this part should not be selected for new designs or long-term production commitments.

Frequently Asked Questions (FAQ)

Q: Can the MBR2550CT be used as a direct replacement for the MBR2050CTHC0G?

A: The MBR2550CT is mechanically compatible (identical TO-220-3 package and through-hole mounting) and electrically compatible for applications where the circuit current requirement does not exceed 15 A per diode. The MBR2550CT has a lower average rectified current rating (15 A versus 20 A). If the application requires 20 A operation, the MBR2550CT is not suitable. Both parts share identical voltage rating (50 V), diode configuration (1 Pair Common Cathode), and Schottky technology.

Q: What are the key differences between these parts?

A: The primary differences are: (1) Current rating: MBR2050CTHC0G is rated for 20 A per diode, while MBR2550CT is rated for 15 A per diode; (2) Reverse leakage current: MBR2050CTHC0G has 100 µA @ 50 V, while MBR2550CT has 1 mA @ 50 V; (3) Product status: MBR2050CTHC0G is Active, while MBR2550CT is Obsolete; (4) Operating temperature range: MBR2050CTHC0G operates from -55°C to 150°C, while MBR2550CT operates from -65°C to 150°C.

Q: Are both parts qualified to the same automotive standards?

A: The MBR2050CTHC0G is qualified to AEC-Q101 automotive standards. The MBR2550CT product data provided does not specify AEC-Q101 qualification status. Both parts are ROHS3 compliant.

Q: What is the significance of the Obsolete product status for the MBR2550CT?

A: Obsolete product status indicates that the MBR2550CT is no longer in active production and is not recommended for new designs or long-term production commitments. Inventory availability is finite, and future supply cannot be guaranteed. The MBR2050CTHC0G, with Active status, is the appropriate choice for new designs and applications requiring sustained production.

Q: Can I use the MBR2050CTHC0G in an application designed for the MBR2550CT?

A: Yes. The MBR2050CTHC0G has a higher current rating (20 A versus 15 A) and lower reverse leakage current (100 µA versus 1 mA), making it suitable for any application that accepts the MBR2550CT. The MBR2050CTHC0G provides improved performance margins and is the preferred choice due to its Active product status.

Q: Are the pin configurations identical between these parts?

A: Both parts use the TO-220-3 package with identical pin configuration for the 1 Pair Common Cathode diode array topology. Physical mounting and electrical connection are identical.
