Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRS3201T3 is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 3 A minimum
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Technology: Schottky

Secondary Compatibility Factors:

• Reverse Recovery Time (trr): 35 ns or faster
• Operating Temperature Range: -55°C to 150°C or wider
• Forward Voltage (Vf): Within acceptable circuit tolerance

Substitute parts are classified into two categories:

Direct Equivalent (Identical Electrical Specifications): MBRS3201T3G meets all primary and secondary criteria with identical electrical performance and package configuration. This part is manufactured by onsemi and maintains the same base product number (MBRS3201).

Functional Equivalent (Meets or Exceeds Electrical Requirements): SK3200-TP and SK4200L-TP are manufactured by Micro Commercial Co and satisfy all primary substitution criteria. SK3200-TP maintains 3A current rating with identical voltage and package specifications. SK4200L-TP provides 4A current rating, exceeding the 3A requirement while maintaining 200V voltage rating and identical package configuration.

Engineering Selection Recommendations

MBRS3201T3G (Direct Equivalent - Recommended Primary Choice)

The MBRS3201T3G is the direct equivalent substitute for the obsolete MBRS3201T3. Both parts are manufactured by onsemi and share identical electrical specifications, including 200V reverse voltage, 3A average rectified current, 840 mV forward voltage at 3A, and 35 ns reverse recovery time. The MBRS3201T3G is classified as Active product status with 19,013 pieces in inventory, ensuring reliable long-term availability. The primary distinction is regulatory compliance: MBRS3201T3G is ROHS3 compliant, whereas the original MBRS3201T3 is RoHS non-compliant. For applications subject to RoHS requirements or environmental regulations, MBRS3201T3G is the appropriate selection. Packaging is available in Cut Tape (CT) and Digi-Reel® formats.

SK3200-TP (Functional Equivalent - Alternative Choice)

The SK3200-TP manufactured by Micro Commercial Co is a functional equivalent that meets all primary substitution criteria. It maintains 200V reverse voltage and 3A average rectified current in the identical DO-214AB SMC package. The forward voltage is 860 mV at 3A, representing a 20 mV increase compared to the MBRS3201T3. This difference is within typical circuit tolerance margins for most applications. The SK3200-TP is Active product status with 17,030 pieces in inventory. Reverse leakage current is 500 µA at 200V, lower than the original part's 1 mA specification, which represents improved performance. The SK3200-TP is ROHS3 compliant and available in Tape & Reel (TR) packaging.

SK4200L-TP (Functional Equivalent with Increased Current Rating)

The SK4200L-TP manufactured by Micro Commercial Co is a functional equivalent with enhanced current capacity. It maintains 200V reverse voltage while providing 4A average rectified current, exceeding the 3A requirement of the original MBRS3201T3. The forward voltage is 860 mV at 4A. This part is suitable for applications where current margin or future design headroom is required. The SK4200L-TP is Active product status with 4,200 pieces in inventory. Reverse leakage current is 500 µA at 200V. The part is ROHS3 compliant and available in Cut Tape (CT) and Digi-Reel® packaging. The increased current rating does not affect package dimensions or mounting compatibility.

Compliance Considerations

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The original MBRS3201T3 is RoHS non-compliant; therefore, new designs or production requiring regulatory compliance must transition to MBRS3201T3G, SK3200-TP, or SK4200L-TP.

Frequently Asked Questions (FAQ)

Q: Can MBRS3201T3G be used as a direct replacement for MBRS3201T3?

A: Yes. MBRS3201T3G is the direct equivalent substitute manufactured by onsemi. Both parts share identical electrical specifications (200V, 3A, 840 mV forward voltage, 35 ns recovery time) and the same DO-214AB SMC package. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). MBRS3201T3G is recommended for new production and designs requiring regulatory compliance.

Q: What is the difference between SK3200-TP and SK4200L-TP?

A: Both parts are manufactured by Micro Commercial Co and maintain 200V reverse voltage in the DO-214AB SMC package. The primary difference is current rating: SK3200-TP is rated for 3A average rectified current (matching the original MBRS3201T3), while SK4200L-TP is rated for 4A. The forward voltage is 860 mV for both parts. SK4200L-TP provides additional current margin and is suitable for applications requiring higher current capacity or design headroom.

Q: Is the 20 mV increase in forward voltage (860 mV vs. 840 mV) significant?

A: The 20 mV difference between SK3200-TP/SK4200L-TP (860 mV @ rated current) and MBRS3201T3 (840 mV @ 3A) is within typical circuit tolerance margins for most rectifier applications. This represents approximately 2.4% variation. Circuit designers should verify that this forward voltage increase does not exceed the maximum allowable voltage drop in their specific application. For applications with tight voltage regulation requirements, MBRS3201T3G maintains the original 840 mV specification.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts (MBRS3201T3G, SK3200-TP, SK4200L-TP) use the DO-214AB SMC package with Surface Mount configuration. Mechanical compatibility and PCB footprint are identical. Packaging format differs: MBRS3201T3G is available in Cut Tape (CT) and Digi-Reel®; SK3200-TP is available in Tape & Reel (TR); SK4200L-TP is available in Cut Tape (CT) and Digi-Reel®. These packaging differences do not affect component performance or board-level compatibility.

Q: What is the reverse leakage current difference between the original part and substitutes?

A: The MBRS3201T3 specifies 1 mA reverse leakage at 200V. SK3200-TP and SK4200L-TP specify 500 µA at 200V, representing 50% lower leakage. Lower reverse leakage is generally beneficial for circuit performance and does not create compatibility issues. MBRS3201T3G maintains the original 1 mA specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. MBRS3201T3G, SK3200-TP, and SK4200L-TP are all ROHS3 compliant. The original MBRS3201T3 is RoHS non-compliant. For applications or markets requiring RoHS compliance, any of the three substitute parts are acceptable. All parts are REACH unaffected.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring direct electrical equivalence and RoHS compliance, MBRS3201T3G is the recommended choice. It is manufactured by onsemi (original manufacturer) and maintains identical electrical specifications. For designs where alternative manufacturers are acceptable and current margin is desired, SK4200L-TP provides 4A capacity in the same package. For cost-optimized designs with 3A requirement, SK3200-TP is a functional equivalent.

Q: What is the inventory status of each substitute part?

A: MBRS3201T3G has 19,013 pieces in inventory (Active status). SK3200-TP has 17,030 pieces in inventory (Active status). SK4200L-TP has 4,200 pieces in inventory (Active status). All parts are classified as Active product status, ensuring ongoing availability and supply chain continuity.
