Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRI20100CT is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid substitute relationships:

Primary Substitution Criteria:

• 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-262-3 Long Leads, I2PAK, TO-262AA (mandatory match)

Secondary Compatibility Parameters:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 20 A
• Voltage - Forward (Vf) (Max) @ If: Must be specified at equivalent current levels
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (preferred for performance continuity)
• Current - Reverse Leakage @ Vr: Lower values indicate superior performance
• Operating Temperature - Junction: Must encompass or exceed -55°C to 150°C range
• RoHS Status: ROHS3 Compliant (mandatory for regulatory compliance)

Substitute parts are grouped into two categories: Direct Equivalents (matching all primary and secondary parameters) and Functional Alternatives (matching primary criteria with acceptable parameter variations).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - Preferred Substitution:

The STPS41H100CR (STMicroelectronics) is the primary direct equivalent for the MBRI20100CT. This part matches all mandatory substitution criteria: 1 Pair Common Cathode configuration, Schottky technology, 100 V reverse voltage rating, 20 A average rectified current per diode, TO-262-3 Long Leads (I2PAK) package, and through-hole mounting. The STPS41H100CR carries Active product status, ensuring long-term availability and manufacturing support. It is ROHS3 Compliant with MSL 1 (Unlimited) rating. The forward voltage specification of 800 mV @ 20 A is superior to the main part's 950 mV @ 20 A, indicating improved efficiency characteristics. The maximum junction temperature of 175°C exceeds the main part's upper limit of 150°C, providing enhanced thermal margin. Reverse leakage current of 10 µA @ 100 V is significantly lower than the main part's 100 µA, demonstrating superior leakage performance. This part is available in high inventory (11,900 pcs).

Functional Alternative - Current-Limited Substitution:

The VI20100C-E3/4W (Vishay General Semiconductor - Diodes Division) and NTSB20U100CT-1G (onsemi) are functional alternatives that match all mandatory package and configuration criteria but operate at reduced current ratings of 10 A per diode. These parts are suitable for applications where the 20 A current capacity of the main part is not fully utilized. The VI20100C-E3/4W carries Active product status with 1,400 pcs in inventory. The NTSB20U100CT-1G is marked Obsolete and should not be selected for new applications or long-term production commitments. Both alternatives feature Fast Recovery switching characteristics (≤ 500ns, > 200mA) and forward voltage specifications of 790 mV @ 10 A. Operating temperature ranges are -40°C to 150°C, which do not extend to the main part's lower limit of -55°C.

Package Variant - Not Recommended:

The MBR20100CT (Good-Ark Semiconductor) differs in package configuration, utilizing TO-220-3 Full Pack with Isolated Tab instead of the TO-262-3 Long Leads (I2PAK) format. Although it maintains the 100 V reverse voltage and 1 Pair Common Cathode configuration, the package incompatibility prevents direct substitution in existing PCB designs. This part is rated at 10 A average rectified current and carries Active product status. Selection of this part requires PCB redesign and mechanical re-qualification.

Obsolete Part - Not Recommended:

The NTSB20U100CT-1G carries Obsolete product status and should not be selected for new designs or production commitments requiring long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can the STPS41H100CR directly replace the MBRI20100CT without PCB modifications?

A: Yes. The STPS41H100CR is a direct package and electrical equivalent. Both parts use the TO-262-3 Long Leads (I2PAK) package with identical pinout and mounting footprint. No PCB modifications are required. The STPS41H100CR meets or exceeds all electrical specifications of the MBRI20100CT.

Q: What is the primary difference between the STPS41H100CR and the VI20100C-E3/4W?

A: The STPS41H100CR is rated for 20 A average rectified current per diode, matching the MBRI20100CT's current capacity. The VI20100C-E3/4W is rated for 10 A average rectified current per diode. Both parts share identical package, voltage rating, and configuration. Selection depends on whether the application requires the full 20 A current capacity.

Q: Why is the MBR20100CT not recommended as a substitute?

A: Although the MBR20100CT maintains the same voltage rating and diode configuration, it uses a different package format (TO-220-3 Full Pack, Isolated Tab) compared to the MBRI20100CT (TO-262-3 Long Leads, I2PAK). The mechanical incompatibility prevents direct substitution and requires PCB redesign. Additionally, the MBR20100CT is rated for only 10 A average rectified current.

Q: Is the NTSB20U100CT-1G suitable for new production?

A: No. The NTSB20U100CT-1G carries Obsolete product status and should not be selected for new designs or production commitments. Although it matches the package and configuration criteria, its obsolescence status indicates limited future availability and manufacturing support.

Q: What are the key electrical advantages of the STPS41H100CR over the MBRI20100CT?

A: The STPS41H100CR demonstrates three measurable electrical improvements: (1) Forward voltage of 800 mV @ 20 A versus 950 mV @ 20 A, reducing power dissipation; (2) Reverse leakage current of 10 µA @ 100 V versus 100 µA @ 100 V, indicating superior junction quality; (3) Maximum junction temperature of 175°C versus 150°C, providing enhanced thermal headroom.

Q: Can the VI20100C-E3/4W be used in applications requiring 20 A current capacity?

A: No. The VI20100C-E3/4W is rated for a maximum average rectified current of 10 A per diode. Using this part in applications requiring 20 A operation will exceed its current rating and result in device failure or reduced reliability. The STPS41H100CR must be selected for 20 A applications.

Q: Are all substitute parts RoHS3 Compliant?

A: Yes. All substitute parts listed (STPS41H100CR, MBR20100CT, NTSB20U100CT-1G, and VI20100C-E3/4W) carry ROHS3 Compliant certification, matching the compliance status of the MBRI20100CT.

Q: What is the Moisture Sensitivity Level (MSL) of the substitute parts?

A: The STPS41H100CR, MBR20100CT, and VI20100C-E3/4W all carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The NTSB20U100CT-1G carries MSL Not Applicable. All parts are suitable for standard storage and handling conditions.

Q: Which substitute part offers the best long-term availability?

A: The STPS41H100CR (STMicroelectronics) carries Active product status with 11,900 pcs in current inventory, providing the strongest assurance of long-term availability and manufacturing support. The VI20100C-E3/4W (Vishay) also carries Active status with 1,400 pcs available. Both are suitable for production commitments.
