MBR1090 Equivalent & Substitute Parts

Part Overview

The MBR1090 is a Schottky rectifier diode rated for 90 V DC reverse voltage and 10 A average rectified current in a Through Hole TO-220-2 package. Manufactured by onsemi, this component is classified as Obsolete product status. Due to its obsolete classification, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts maintain the core electrical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR1090 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): Substitute must equal or exceed 90 V
• Current - Average Rectified (Io): Substitute must equal or exceed 10 A
• Voltage - Forward (Vf) (Max) @ If: Substitute must not exceed 800 mV @ 10 A
• Speed: Substitute must maintain Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: Substitute must not exceed 100 µA @ 90 V

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (required)
• Package / Case: TO-220-2 or compatible TO-220 variant (required)

Compliance Criteria:

• Technology: Schottky (required)
• REACH Status: REACH Unaffected (required)
• ECCN: EAR99 (required)

Substitute parts are grouped into two categories: Direct Equivalents (matching all electrical parameters at 90 V rating) and Parametric Equivalents (meeting or exceeding electrical specifications with higher voltage ratings).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitutes (90 V Rating):

The MBR1090-E3/4W and MBR1090-M3/4W from Vishay General Semiconductor - Diodes Division are direct electrical equivalents with identical 90 V reverse voltage and 10 A current ratings. Both parts maintain the same forward voltage specification of 800 mV @ 10 A and reverse leakage of 100 µA @ 90 V. These parts are classified as Active product status and ROHS3 Compliant, addressing the RoHS non-compliance of the original MBR1090. Operating temperature range is -65 to 150°C, which covers the lower end of the original part's -65 to 175°C range.

The MBR1090_T0_00001 from Panjit International Inc. is a parametric equivalent offering identical electrical specifications at 90 V with improved reverse leakage performance (50 µA @ 90 V versus 100 µA @ 90 V). This part maintains the full operating temperature range of -65 to 175°C and is ROHS3 Compliant with Active product status.

Parametric Equivalent Substitutes (100 V Rating):

The MBR10100-BP and MBR10100F-BP from Micro Commercial Co provide higher voltage ratings of 100 V while maintaining 10 A current capacity. These parts are suitable for applications where voltage margin is beneficial. The MBR10100-BP maintains the 800 mV forward voltage specification. The MBR10100F-BP features an isolated tab variant (ITO-220AC) with slightly elevated forward voltage of 850 mV @ 10 A. Both parts are Active product status. Operating temperature ranges are reduced to -55 to 150°C and -50 to 150°C respectively.

Compliance Considerations:

For applications requiring RoHS3 compliance, the Vishay parts (MBR1090-E3/4W, MBR1090-M3/4W) and Panjit part (MBR1090_T0_00001) are suitable replacements. All substitute parts maintain REACH Unaffected and EAR99 ECCN classifications consistent with the original MBR1090.

Frequently Asked Questions (FAQ)

Q: Can MBR10100-BP and MBR10100F-BP be used as direct replacements for MBR1090?

A: Yes, with design considerations. Both parts meet or exceed the electrical specifications of the MBR1090. The 100 V rating provides additional voltage margin beyond the 90 V requirement. However, the operating temperature range is reduced to -55 to 150°C and -50 to 150°C respectively, compared to the original -65 to 175°C. Applications operating at the temperature extremes of the original specification require verification of the substitute part's suitability.

Q: What is the difference between MBR1090-E3/4W and MBR1090-M3/4W?

A: Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications: 90 V reverse voltage, 10 A current, 800 mV forward voltage, and 100 µA reverse leakage. The primary difference is packaging: MBR1090-E3/4W is supplied in Tube packaging with 733 Pcs in stock, while MBR1090-M3/4W is also supplied in Tube packaging with 1114 Pcs in stock. Both are ROHS3 Compliant and Active product status.

Q: Why does MBR1090_T0_00001 show lower reverse leakage (50 µA) compared to the original MBR1090 (100 µA)?

A: Lower reverse leakage indicates improved device performance and is a beneficial characteristic. The MBR1090_T0_00001 from Panjit International Inc. demonstrates superior leakage characteristics while maintaining all other electrical specifications. This represents an enhancement over the original part.

Q: Is the isolated tab variant MBR10100F-BP compatible with standard TO-220-2 footprints?

A: The MBR10100F-BP uses an ITO-220AC package (isolated tab variant) while the standard MBR1090 uses TO-220-2. Both are mechanically compatible with Through Hole mounting, but the isolated tab design provides electrical isolation of the tab from the case. PCB layout and thermal management considerations may differ. Verify that the isolated tab configuration is compatible with the application's thermal and electrical requirements.

Q: What is the impact of the 150 µA reverse leakage in MBR10100-BP compared to 100 µA in MBR1090?

A: The MBR10100-BP exhibits 150 µA reverse leakage at 100 V, compared to 100 µA at 90 V in the original MBR1090. Reverse leakage increases with applied voltage; therefore, direct comparison requires consideration of the voltage difference. At the MBR1090's 90 V operating point, the MBR10100-BP's leakage would be lower than the specified 150 µA @ 100 V. Applications sensitive to reverse leakage should evaluate this parameter within their specific operating voltage range.

Q: Are all substitute parts RoHS compliant?

A: The Vishay parts (MBR1090-E3/4W, MBR1090-M3/4W) and Panjit part (MBR1090_T0_00001) are ROHS3 Compliant. The Micro Commercial Co parts (MBR10100-BP, MBR10100F-BP) do not specify RoHS status in the provided data. For applications requiring RoHS compliance, the Vishay and Panjit alternatives are confirmed suitable.

Q: Can MBR1090_T0_00001 be used in applications requiring the full -65 to 175°C temperature range?

A: Yes. The MBR1090_T0_00001 maintains the full operating temperature range of -65 to 175°C, matching the original MBR1090. This part is suitable for applications requiring operation across the complete temperature specification.
