Engineering Selection Recommendations

Parametric Equivalent - Same Manufacturer:

MBRB10H100CT-E3/81 (Vishay General Semiconductor - Diodes Division) is a parametric equivalent offering identical electrical specifications to the MBRB10H100CT/31. This part maintains the same 100 V reverse voltage, 5 A current rating, and 760 mV forward voltage characteristics. The primary distinction is ROHS3 compliance and availability in Tape & Reel packaging. This substitute is suitable for applications requiring continuity with the original Vishay product line while upgrading to compliant materials.

Direct Equivalent - Alternative Manufacturer:

MBRB10100CT (SMC Diode Solutions) is an active product offering the same diode array configuration in TO-263-3 D2PAK packaging. This part maintains 100 V reverse voltage and common cathode configuration. Forward voltage specification is 850 mV @ 5 A, which exceeds the original 760 mV specification. This part is ROHS3 compliant and available in Cut Tape and Digi-Reel® formats with high inventory availability (7695 units).

STPS10H100CG-TR (STMicroelectronics) provides an active alternative with identical 100 V reverse voltage and 5 A current rating. Forward voltage is specified at 730 mV @ 5 A, which is lower than the original 760 mV specification. This part is ROHS3 compliant, REACH unaffected, and available in Cut Tape & Digi-Reel® packaging with 4960 units in stock.

Manufacturer-Recommended Upgrade:

STPS20H100CG and STPS20H100CG-TR (STMicroelectronics) are manufacturer-recommended upgrades featuring doubled current capacity at 10 A per diode while maintaining 100 V reverse voltage. These parts are ROHS3 compliant, active products with superior inventory availability (170,801 and 90,200 units respectively). The higher current rating provides design margin for applications with variable load conditions. Forward voltage is specified at 770 mV @ 10 A.

Compliance Considerations:

The original MBRB10H100CT/31 is RoHS non-compliant. All recommended substitutes are ROHS3 compliant, supporting transition to compliant supply chains. For applications subject to REACH regulations, STPS10H100CG-TR and STPS20H100CG series are REACH unaffected, while MBRB10100CT is REACH affected.

Frequently Asked Questions (FAQ)

Q: Can MBRB10100CT be used as a direct replacement for MBRB10H100CT/31?

A: MBRB10100CT is mechanically and electrically compatible in the TO-263-3 D2PAK package with matching 100 V reverse voltage and common cathode configuration. The forward voltage specification of 850 mV @ 5 A is higher than the original 760 mV specification. This part is suitable for applications where forward voltage drop is not a critical design parameter. Verify thermal performance in your specific application.

Q: What is the difference between STPS10H100CG-TR and STPS20H100CG-TR?

A: Both parts are STMicroelectronics Schottky diode arrays in TO-263-3 D2PAK packaging with 100 V reverse voltage. The primary difference is current rating: STPS10H100CG-TR is rated for 5 A per diode, while STPS20H100CG-TR is rated for 10 A per diode. Forward voltage at rated current is 730 mV @ 5 A for the STPS10 and 770 mV @ 10 A for the STPS20. Both are ROHS3 compliant and active products.

Q: Is MBRB10H100CT-E3/81 identical to MBRB10H100CT/31?

A: MBRB10H100CT-E3/81 is a parametric equivalent with identical electrical specifications: 100 V reverse voltage, 5 A current rating, 760 mV forward voltage @ 5 A, and -65°C to 150°C operating temperature range. The key difference is ROHS3 compliance versus RoHS non-compliance in the original part. Packaging format differs: the -E3/81 variant is supplied in Tape & Reel format.

Q: Can STPS20H100CG be used in place of MBRB10H100CT/31?

A: STPS20H100CG is mechanically compatible in the TO-263-3 D2PAK package and maintains the 100 V reverse voltage and common cathode configuration. The current rating is doubled to 10 A per diode, providing design margin. Forward voltage is 770 mV @ 10 A compared to the original 760 mV @ 5 A. This part is ROHS3 compliant and an active product with extensive inventory availability.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT), Digi-Reel®, and Tape & Reel (TR). MBRB10H100CT-E3/81 is supplied in Tape & Reel format. MBRB10100CT and STPS10H100CG-TR are available in Cut Tape & Digi-Reel® format. STPS20H100CG is available without specified packaging format, while STPS20H100CG-TR is supplied in Cut Tape & Digi-Reel® format. Verify packaging requirements for your assembly process.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts are ROHS3 compliant. The original MBRB10H100CT/31 is RoHS non-compliant. Substitution with any of the recommended parts supports transition to compliant supply chains and regulatory requirements.

Q: What is the operating temperature range difference between substitute parts?

A: The original MBRB10H100CT/31 operates from -65°C to 150°C junction temperature. MBRB10100CT operates from -55°C to 150°C, providing a narrower low-temperature range. STMicroelectronics parts (STPS10H100CG-TR, STPS20H100CG, STPS20H100CG-TR) specify a maximum junction temperature of 175°C, providing higher temperature capability. Verify application temperature requirements when selecting substitutes.
