MBR2035CT Equivalent & Substitute Parts

Part Overview

The MBR2035CT is a Schottky diode array manufactured by SMC Diode Solutions, configured as a 1 Pair Common Cathode arrangement in a TO-220-3 through-hole package. This component is rated for 35 V DC reverse voltage and features fast recovery characteristics suitable for rectification applications. The part maintains Active product status with 1990 units in current inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved within the specified parameter ranges for this diode category. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative sourcing is required while maintaining circuit functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBR2035CT is determined by the following critical parameters:

Mandatory Matching Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 35 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3

Performance Compatibility Criteria:

• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature Range: Must encompass or exceed the application requirements within -55°C to 150°C
• Forward Voltage (Vf): Must not exceed specified maximum at rated current
• Reverse Leakage Current: Must remain within acceptable limits for the application

The MBR1535CTG from onsemi satisfies all mandatory matching criteria and maintains equivalent fast recovery speed performance. This part is identified as a functional substitute despite its Obsolete product status, as it provides the same electrical configuration and mechanical interface required for direct replacement in TO-220-3 through-hole applications.

Engineering Selection Recommendations

Primary Part Selection: The MBR2035CT is the preferred selection for new designs and applications requiring active product status with ongoing manufacturer support. This part carries Active product status from SMC Diode Solutions and maintains full RoHS3 compliance with REACH Affected designation.

Substitute Part Consideration: The MBR1535CTG from onsemi functions as an electrical and mechanical equivalent for existing applications currently using the MBR2035CT. However, this part carries Obsolete product status, indicating discontinued manufacturing and limited future availability. The MBR1535CTG is suitable for replacement in fielded equipment or legacy system maintenance where inventory exists.

Compliance Considerations: Both parts maintain ROHS3 compliance. The MBR2035CT is REACH Affected, while the MBR1535CTG is REACH Unaffected. Applications subject to REACH regulatory requirements should verify compliance status against specific substance restrictions applicable to the end-use market.

Thermal Performance: The MBR1535CTG provides an extended operating temperature range (-65°C to 175°C) compared to the MBR2035CT (-55°C to 150°C). Applications operating at temperature extremes should confirm that the selected part's thermal range encompasses the required operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the MBR1535CTG directly replace the MBR2035CT in existing circuits?

A: Yes. Both parts share identical diode configuration (1 Pair Common Cathode), Schottky technology, 35 V reverse voltage rating, fast recovery speed characteristics, and TO-220-3 through-hole package. Mechanical and electrical interfaces are compatible for direct substitution.

Q: What are the differences in forward voltage characteristics between these parts?

A: The MBR2035CT specifies 700 mV maximum forward voltage at 10 A, while the MBR1535CTG specifies 840 mV maximum at 15 A. The MBR1535CTG exhibits higher forward voltage drop at its rated current. Circuit designs sensitive to forward voltage losses should account for this 140 mV difference in thermal or efficiency calculations.

Q: Why is the MBR1535CTG listed as Obsolete?

A: Obsolete status indicates that onsemi has discontinued manufacturing of this part. While existing inventory may be available through component distributors, future availability is not guaranteed. New designs should prioritize the Active MBR2035CT to ensure long-term supply chain stability.

Q: Are there differences in reverse leakage current between these parts?

A: Yes. The MBR2035CT specifies 1 mA reverse leakage at 35 V, while the MBR1535CTG specifies 100 µA at 35 V. The MBR1535CTG exhibits lower reverse leakage current by a factor of 10. Applications with stringent leakage requirements should evaluate this parameter against circuit specifications.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). The MBR2035CT is REACH Affected, while the MBR1535CTG is REACH Unaffected. Applications subject to REACH regulations should verify the specific substance restrictions applicable to their end-use market and select accordingly.

Q: What is the significance of the TO-220-3 package designation?

A: TO-220-3 indicates a three-lead through-hole package with a metal mounting tab. Both the MBR2035CT and MBR1535CTG use this identical package, ensuring mechanical compatibility for PCB mounting, thermal management via heatsink attachment, and lead-to-pad alignment without modification.
