MBRM1H100T3G Equivalent & Substitute Parts

Part Overview

The MBRM1H100T3G is a Schottky rectifier diode manufactured by onsemi, rated for 100 V DC reverse voltage and 1 A average rectified current in a Powermite surface mount package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required for design flexibility, supply chain alternatives, or manufacturing process optimization.

Substitute Part Grouping Explanation

Substitution of the MBRM1H100T3G is determined by equivalence in the following critical parameters:

Voltage Rating: Reverse voltage must be 100 V or greater
Current Rating: Average rectified current must support 1 A or greater
Technology: Schottky diode technology
Mounting Type: Surface mount configuration
Speed Characteristics: Fast recovery ≤ 500ns for switching applications
Compliance: RoHS3 compliance and MSL Level 1 rating
Operating Temperature Range: Junction temperature capability of -55°C to 175°C or better

The substitute part SS2PH10-M3/84A meets these criteria with equivalent or superior electrical ratings and maintains compliance certifications. Package differences (DO-220AA versus DO-216AA) represent mechanical variations that may require PCB layout adjustment but do not affect electrical substitution validity.

Engineering Selection Recommendations

MBRM1H100T3G remains the primary selection when the original design specifications require the DO-216AA package form factor, the extended low-temperature operating range of -65°C, or when the 1 A current rating is the design constraint.

SS2PH10-M3/84A is a valid substitute when:

The application circuit can accommodate the DO-220AA package footprint
The operating temperature minimum of -55°C satisfies system requirements
The higher 2 A current rating provides design margin or future scalability
Supply chain availability or cost optimization favors the Vishay component

Both parts maintain Active product status, RoHS3 compliance, and MSL Level 1 rating. No additional qualification testing is required based on compliance certifications alone. PCB layout modifications are necessary due to package differences.

Frequently Asked Questions (FAQ)

Q: Can SS2PH10-M3/84A directly replace MBRM1H100T3G without PCB modification?

A: Electrical substitution is valid. However, the package change from DO-216AA to DO-220AA requires PCB footprint modification. Physical dimensions and pin spacing differ between these packages.

Q: What is the impact of the higher 2 A current rating in the substitute part?

A: The SS2PH10-M3/84A is rated for 2 A average rectified current versus 1 A for the MBRM1H100T3G. This provides additional current capacity and thermal margin in the same application. No circuit redesign is required.

Q: Are there temperature range limitations when using SS2PH10-M3/84A?

A: The substitute part operates from -55°C to 175°C junction temperature, compared to -65°C to 175°C for the original part. If the application requires operation below -55°C, the MBRM1H100T3G must be retained.

Q: How do the reverse leakage characteristics compare?

A: The SS2PH10-M3/84A exhibits 1 µA reverse leakage at 100 V, compared to 20 µA for the MBRM1H100T3G. Lower leakage current in the substitute part may improve circuit performance in high-impedance applications.

Q: Are both parts available in the same packaging format?

A: The MBRM1H100T3G is supplied in Tape & Reel (TR) format in Powermite package. The SS2PH10-M3/84A is available in Cut Tape (CT) and Digi-Reel® format in DO-220AA (SMP) package. Packaging format and supplier device package differ between the two parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MBRM1H100T3G and SS2PH10-M3/84A are RoHS3 compliant, REACH unaffected, and classified as MSL Level 1 (Unlimited). ECCN and HTSUS classifications are identical.
