MBR10100ULPS-TP Equivalent & Substitute Parts

Part Overview

The MBR10100ULPS-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 100 V DC reverse voltage and 10 A average rectified current in a surface mount TO-277-3 package. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design requirements and procurement needs. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within acceptable parameter ranges for the application category.

Substitute Part Grouping Explanation

Substitution of the MBR10100ULPS-TP is determined by the following critical parameters: voltage rating (100 V DC reverse), current capacity (10 A or higher), Schottky technology, surface mount configuration, and TO-277 package family compatibility. Parts are grouped into two categories:

Direct Equivalents: Parts maintaining identical voltage and current ratings (100 V, 10 A) with compatible package designations.

Functional Substitutes: Parts with equal or higher voltage ratings (100 V minimum) and equal or higher current capacity (10 A or greater) that operate within the same temperature range and package family, allowing circuit-level compatibility with potential performance improvements.

The following parameters establish substitution validity: DC reverse voltage ≥ 100 V, average rectified current ≥ 10 A, fast recovery Schottky technology, surface mount configuration, and TO-277 package series.

Engineering Selection Recommendations

MBR15U100L-TP (Micro Commercial Co): This part is the primary substitute for the MBR10100ULPS-TP. It maintains the 100 V voltage rating and TO-277 package compatibility while providing increased current capacity at 15 A. The part is currently in active production status, ensuring long-term availability. RoHS3 compliance and unlimited moisture sensitivity level (MSL 1) match the original specification. The operating temperature range extends to 150°C, which is acceptable for most applications requiring the original -55 to 175°C range, though the upper limit is reduced by 25°C. This part is suitable for direct replacement in applications where the higher current rating does not create thermal or design conflicts.

FSV10100V (onsemi): This part provides electrical equivalence to the MBR10100ULPS-TP with identical 100 V and 10 A ratings in the TO-277-3 package. The forward voltage is lower at 670 mV compared to 700 mV, and reverse leakage is significantly lower at 60 µA. However, the product status is classified as "Not For New Designs," limiting its suitability for new development. This part is appropriate for legacy system maintenance and repair applications where the original specification must be maintained precisely.

V8PM10S-M3/H (Vishay General Semiconductor): This part operates at 100 V with 8 A current capacity, which is below the original 10 A specification. The operating temperature range extends to 175°C, matching the original upper limit. This part is suitable only in applications where the 8 A current rating is sufficient and where the 2 A reduction in capacity does not compromise circuit performance. The part is in active production status with full RoHS3 compliance.

For new designs, MBR15U100L-TP is the recommended primary substitute. For legacy system support, FSV10100V provides electrical equivalence. V8PM10S-M3/H is suitable only when current requirements are confirmed to be 8 A or less.

Frequently Asked Questions (FAQ)

Q: Can MBR15U100L-TP directly replace MBR10100ULPS-TP in all applications?

A: MBR15U100L-TP is mechanically and electrically compatible for direct replacement in the TO-277 package footprint. The higher 15 A current rating is backward compatible with 10 A applications. However, the maximum operating temperature is reduced from 175°C to 150°C. Verify that your application does not require operation above 150°C junction temperature before substitution.

Q: What is the difference between TO-277-3 and TO-277 package designations?

A: Both designations refer to the same TO-277 package family with 3-pin PowerDFN configuration. The "-3" suffix in TO-277-3 explicitly indicates the 3-pin variant. MBR15U100L-TP uses the TO-277 designation and is compatible with TO-277-3 footprints.

Q: Why is FSV10100V marked "Not For New Designs"?

A: This product status indicates that onsemi has discontinued active development and marketing of this part. While the part remains available in inventory, it is not recommended for new circuit designs. FSV10100V is appropriate for repair and maintenance of existing systems using this component.

Q: Is V8PM10S-M3/H suitable as a substitute if my circuit only requires 8 A?

A: Yes, V8PM10S-M3/H is suitable for applications confirmed to operate at 8 A or below. The 100 V voltage rating and Schottky technology match the original specification. The operating temperature range extends to 175°C, providing full compatibility with the original temperature specification. Verify circuit current requirements before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts (MBR15U100L-TP, FSV10100V, and V8PM10S-M3/H) are RoHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), matching the original MBR10100ULPS-TP specification.

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

A: Forward voltage differences (700 mV original, 670 mV FSV10100V, 820 mV MBR15U100L-TP, 780 mV V8PM10S-M3/H) affect power dissipation and voltage drop across the diode. Lower forward voltage reduces heat generation. Verify that your circuit design accommodates the forward voltage range of the selected substitute part, particularly in high-current or thermally constrained applications.

Q: Can reverse leakage current differences affect circuit operation?

A: Reverse leakage current varies among substitutes (500 µA original, 200 µA MBR15U100L-TP, 60 µA FSV10100V, 200 µA V8PM10S-M3/H). Lower leakage current reduces standby power consumption and improves circuit efficiency. Higher leakage has minimal impact in most rectifier applications but may affect precision analog circuits. Verify leakage specifications against circuit requirements.
