Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBRF10H100/45 are classified based on electrical parameter compatibility within the Schottky rectifier diode category. The primary substitution criteria are:

Electrical Compatibility Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 10 A or greater
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Compatibility Parameters:

• Mounting Type: Through Hole
• Package / Case: TO-220-2 configuration with isolated tab capability

Compliance Parameters:

• RoHS Status and REACH Status alignment
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting these criteria are classified as direct electrical and mechanical equivalents. Parts with reduced current ratings (8 A versus 10 A) are classified as functional substitutes where application current requirements do not exceed the substitute part's rating.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (100 V, 10 A Rating):

MBR10100 (Taiwan Semiconductor Corporation) and MBRF10100 (Taiwan Semiconductor Corporation) are direct electrical equivalents to the MBRF10H100/45. Both parts maintain the 100 V reverse voltage and 10 A current ratings with identical fast recovery speed characteristics. Both substitute parts are ROHS3 compliant, addressing regulatory requirements where the original Vishay part is RoHS non-compliant. The MBRF10100 variant offers higher inventory availability (5123 units) compared to the MBR10100 (1847 units).

Operating temperature range differences exist: the original part operates from -65°C to 175°C, while both TSC substitutes operate from -55°C to 150°C. Forward voltage characteristics differ slightly, with TSC parts rated at 850 mV versus 770 mV for the Vishay part. Reverse leakage current is higher in TSC parts (100 µA versus 4.5 µA).

Functional Substitute (100 V, 8 A Rating):

STPS8H100FP (STMicroelectronics) is a functional substitute where application current requirements do not exceed 8 A. This part maintains 100 V reverse voltage rating and fast recovery speed. The STPS8H100FP offers superior forward voltage characteristics (710 mV @ 8 A) and reverse leakage current (4.5 µA) matching the original Vishay specification. The part is ROHS3 compliant with maximum junction temperature of 175°C. Package configuration includes TO-220-2 Full Pack with isolated tab, matching the original part's mechanical requirements. Inventory availability is 4423 units.

Selection between substitute parts depends on application current requirements, regulatory compliance mandates, and thermal operating range constraints.

Frequently Asked Questions (FAQ)

Q: Can MBR10100 directly replace MBRF10H100/45 in all applications?

A: MBR10100 is a direct electrical equivalent for applications operating within -55°C to 150°C junction temperature range. The part maintains 100 V reverse voltage and 10 A current ratings. Forward voltage is higher (850 mV versus 770 mV), and reverse leakage current is higher (100 µA versus 4.5 µA). Verify application thermal and leakage specifications before substitution.

Q: What is the difference between MBR10100 and MBRF10100?

A: Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications (100 V, 10 A, fast recovery Schottky). MBR10100 uses TO-220AC package configuration, while MBRF10100 uses ITO-220AC package configuration. MBRF10100 offers higher inventory availability (5123 units versus 1847 units). Package selection depends on specific PCB layout and thermal management requirements.

Q: Can STPS8H100FP replace MBRF10H100/45?

A: STPS8H100FP is a functional substitute for applications where maximum current requirement does not exceed 8 A. The part maintains 100 V reverse voltage rating and fast recovery speed. Forward voltage (710 mV @ 8 A) and reverse leakage current (4.5 µA) are superior to the original part. Operating temperature range extends to 175°C maximum. Substitution is valid only when application current does not exceed 8 A continuous operation.

Q: What are the compliance differences between the original part and substitutes?

A: MBRF10H100/45 is RoHS non-compliant. Both MBR10100 and MBRF10100 (TSC) are ROHS3 compliant. STPS8H100FP (STMicroelectronics) is ROHS3 compliant. All parts are REACH Unaffected. Substitution with compliant parts addresses regulatory requirements for RoHS-restricted applications.

Q: Are package configurations interchangeable?

A: MBRF10H100/45 uses ITO-220AC package with isolated tab. MBR10100 uses TO-220AC package. MBRF10100 uses ITO-220AC package. STPS8H100FP uses TO-220FPAC package. All configurations are through-hole TO-220-2 variants with isolated tab capability. PCB footprint compatibility exists across all variants. Verify specific thermal management and isolation requirements for your application.

Q: What is the impact of higher reverse leakage current in TSC substitutes?

A: MBR10100 and MBRF10100 exhibit 100 µA reverse leakage at 100 V compared to 4.5 µA in the original Vishay part. This 22-fold increase affects power dissipation in standby conditions and may impact precision analog circuits. Applications with strict leakage specifications should select STPS8H100FP (4.5 µA) or retain the original Vishay part.

Q: What is the forward voltage impact on circuit performance?

A: MBRF10H100/45 forward voltage is 770 mV @ 10 A. TSC substitutes (MBR10100, MBRF10100) are rated at 850 mV @ 10 A, representing 80 mV higher drop. STPS8H100FP is rated at 710 mV @ 8 A. Higher forward voltage increases power dissipation and heat generation. Circuits with tight voltage margin specifications should account for this difference.

Q: Is thermal management affected by substitute selection?

A: Original part operates -65°C to 175°C. TSC substitutes operate -55°C to 150°C, representing 15°C lower maximum junction temperature. STPS8H100FP maximum junction temperature is 175°C. Applications requiring full -65°C to 175°C range must retain the original Vishay part or select STPS8H100FP (with 8 A current limitation). TSC substitutes are suitable for -55°C to 150°C applications.
