Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB10H90HE3_A/I is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 90V
• Current - Average Rectified (Io): 10A
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Technology: Schottky

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must satisfy all mandatory matching parameters to ensure functional and mechanical compatibility. Compliance parameters must be maintained to support regulatory and supply chain requirements. Variations in secondary electrical characteristics (forward voltage, reverse leakage current, operating temperature range) are acceptable provided the substitute part meets or exceeds the primary electrical ratings and maintains the specified package configuration.

Parameter Comparison

Engineering Selection Recommendations

The MBRS1090 MNG manufactured by Taiwan Semiconductor Corporation is a direct functional substitute for the obsolete MB10H90HE3_A/I. Both components share identical voltage and current ratings, package configuration, and fast recovery speed characteristics. The substitute part is currently in active production status, ensuring supply chain availability.

Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity classification, supporting regulatory and handling requirements. The operating temperature range of the substitute part (-55°C ~ 175°C) covers the upper temperature specification of the original part, with the lower temperature limit reduced by 10°C. This difference is acceptable for applications operating within the substitute part's specified range.

The reverse leakage current specification of the MBRS1090 MNG (100 µA @ 90V) is higher than the original part (4.5 µA @ 90V). This parameter difference is acceptable for general rectification applications and does not compromise the substitute part's suitability for standard power conversion circuits.

Selection of the MBRS1090 MNG eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the MBRS1090 MNG be used as a direct replacement for the MB10H90HE3_A/I in existing designs?

A: Yes. Both parts share identical voltage ratings (90V), current ratings (10A), package configuration (TO-263AB), and mounting type (surface mount). The parts are pin-compatible and functionally equivalent for rectification applications.

Q: What is the significance of the higher reverse leakage current in the MBRS1090 MNG?

A: The MBRS1090 MNG specifies 100 µA reverse leakage at 90V compared to 4.5 µA for the original part. This difference reflects normal manufacturing variation between suppliers and does not affect performance in standard rectification circuits. Applications with specific leakage current requirements should evaluate this parameter against circuit specifications.

Q: Does the reduced lower operating temperature limit of the MBRS1090 MNG affect compatibility?

A: The MBRS1090 MNG operates from -55°C to 175°C, compared to -65°C to 175°C for the original part. The substitute part is suitable for applications operating within its specified temperature range. Applications requiring operation below -55°C require evaluation against specific circuit requirements.

Q: Are both parts automotive-grade qualified?

A: The MB10H90HE3_A/I carries AEC-Q101 automotive qualification. The MBRS1090 MNG specifications provided do not include automotive qualification details. Applications requiring automotive-grade certification should verify qualification status with the manufacturer.

Q: What is the package compatibility between these parts?

A: Both parts use the TO-263-3 package, also designated as D2PAK (2 Leads + Tab) or TO-263AB. The parts are mechanically and electrically compatible for PCB mounting and thermal management applications.

Q: Why is the original MB10H90HE3_A/I classified as obsolete?

A: Obsolescence classification indicates the part is no longer in active production. The MBRS1090 MNG provides equivalent functionality with active production status, ensuring long-term supply availability.
