Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF2090CT-M3/4W is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Current - Average Rectified (Io): 10 A per diode
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack

Allowable Parameter Variations:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 90 V
• Voltage - Forward (Vf) (Max) @ If: May vary within application tolerance
• Current - Reverse Leakage @ Vr: May vary within application tolerance
• Operating Temperature - Junction (Max): Equal to or greater than 150°C
• Supplier Device Package: TO-220FP or TO-220FN acceptable (functionally equivalent to ITO-220AB)

All substitute parts listed maintain the same diode configuration, technology, current rating, and through-hole mounting requirement. Voltage ratings of 100 V provide additional design margin over the 90 V specification. Operating temperature maximums of 175°C exceed the base requirement of 150°C.

Parameter Comparison

Engineering Selection Recommendations

MBRF20100CTG (onsemi)

The MBRF20100CTG is a direct functional equivalent with 100 V voltage rating, providing 10 V additional reverse voltage margin. Operating temperature maximum of 175°C exceeds the base requirement. RoHS3 compliance and REACH unaffected status match the original specification. This part is suitable for applications requiring higher voltage headroom while maintaining identical current and configuration specifications.

RB215T-90 (Rohm Semiconductor)

The RB215T-90 maintains the 90 V voltage rating and 10 A current specification of the original part. Forward voltage is 750 mV at 10 A, lower than the 800 mV specification. Operating temperature maximum of 150°C matches the base requirement. RoHS3 compliance and REACH unaffected status are maintained. This part is suitable for direct replacement in applications where voltage rating and thermal performance are not limiting factors.

STPS20H100CFP (STMicroelectronics)

The STPS20H100CFP features 100 V voltage rating with 175°C maximum operating temperature, exceeding both the voltage and thermal specifications of the original part. Reverse leakage current is 4.5 µA at 100 V, significantly lower than the 100 µA specification. RoHS3 compliance and REACH unaffected status are maintained. This part is suitable for applications requiring superior thermal performance and lower leakage characteristics.

STPS20S100CFP (STMicroelectronics)

The STPS20S100CFP provides 100 V voltage rating with 175°C maximum operating temperature. Reverse leakage current is 3.5 µA at 100 V, the lowest among all substitutes. RoHS3 compliance and REACH unaffected status are maintained. This part is suitable for applications requiring the lowest reverse leakage current combined with enhanced thermal capability.

Frequently Asked Questions (FAQ)

Q: Can the MBRF20100CTG replace the MBRF2090CT-M3/4W in all applications?

A: The MBRF20100CTG is functionally compatible as a substitute. The 100 V rating provides additional voltage margin over the 90 V specification. Forward voltage is 850 mV versus 800 mV, and operating temperature maximum is 175°C versus 150°C. Compatibility depends on application-specific requirements for voltage headroom and thermal performance.

Q: What is the difference between the RB215T-90 and the original MBRF2090CT-M3/4W?

A: Both parts share the same 90 V voltage rating and 10 A current specification. The RB215T-90 has lower forward voltage (750 mV versus 800 mV) and higher reverse leakage current (400 µA versus 100 µA). Operating temperature maximum is identical at 150°C. The RB215T-90 is suitable for applications where lower forward voltage is beneficial and reverse leakage is not a limiting factor.

Q: Why do the STMicroelectronics parts (STPS20H100CFP and STPS20S100CFP) have significantly lower reverse leakage current?

A: Reverse leakage current is a manufacturing and design characteristic that varies among manufacturers and part series. The STMicroelectronics STPS20 series exhibits lower reverse leakage (4.5 µA and 3.5 µA respectively) compared to the original specification (100 µA). This characteristic is provided in the component datasheets and reflects the inherent performance of each device design.

Q: Are all substitute parts available in the same package configuration?

A: All substitute parts are housed in TO-220-3 Full Pack configuration suitable for through-hole mounting. The MBRF2090CT-M3/4W specifies an isolated tab variant (ITO-220AB). Substitute parts use standard TO-220FP or TO-220FN packages. Pin configuration and mounting compatibility are maintained across all listed substitutes.

Q: What compliance certifications apply to all listed parts?

A: All parts listed are RoHS3 compliant and REACH unaffected. The MBRF2090CT-M3/4W has Moisture Sensitivity Level (MSL) of 1 (Unlimited). The MBRF20100CTG lists MSL as Not Applicable. The STMicroelectronics and Rohm parts maintain MSL 1 (Unlimited). All parts carry ECCN EAR99 and HTSUS 8541.10.0080 classifications.

Q: Can the STPS20H100CFP and STPS20S100CFP be used interchangeably?

A: Both STMicroelectronics parts share identical voltage (100 V), current (10 A), and temperature (175°C maximum) specifications. The primary difference is reverse leakage current: STPS20H100CFP at 4.5 µA versus STPS20S100CFP at 3.5 µA at 100 V. Both are functionally compatible substitutes for the original part. Selection between them depends on application requirements for leakage current performance.

Q: What is the significance of the "1 Pair Common Cathode" configuration?

A: The 1 Pair Common Cathode configuration indicates the diode array contains two diodes with a shared cathode connection. This configuration is essential for specific circuit topologies and cannot be substituted with different configurations. All listed substitute parts maintain this identical configuration.
