MBR4015CTL Equivalent & Substitute Parts

Part Overview

The MBR4015CTL is a Schottky diode array manufactured by onsemi, configured as 1 pair common cathode with a maximum reverse voltage of 15 V and average rectified current of 20 A per diode. This component is packaged in TO-220-3 through-hole configuration and is classified as obsolete product status.

Due to the obsolete status of the MBR4015CTL, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain electrical compatibility within the specified parameter ranges while meeting current manufacturing and compliance standards.

Engineering Selection Recommendations

40CTQ015 (SMC Diode Solutions)

The 40CTQ015 is an active product with identical electrical specifications to the MBR4015CTL at the primary operating point (15 V reverse voltage, 20 A average rectified current). This part demonstrates ROHS3 compliance and is currently in production with substantial inventory availability. The forward voltage specification of 410 mV @ 20 A is lower than the MBR4015CTL, indicating improved efficiency characteristics. The operating temperature range of -55°C ~ 150°C is narrower at the lower bound but maintains the upper temperature limit. This substitute is suitable for applications where the minimum operating temperature requirement does not fall below -55°C.

VS-47CTQ020-M3 (Vishay General Semiconductor - Diodes Division)

The VS-47CTQ020-M3 is an active product with a maximum reverse voltage rating of 20 V, exceeding the MBR4015CTL specification by 5 V. This higher voltage rating provides additional design margin in applications subject to voltage transients or overvoltage conditions. The part maintains the 20 A average rectified current specification and fast recovery speed characteristic. ROHS3 compliance is confirmed. The reverse leakage current of 3 mA @ 20 V is significantly lower than the MBR4015CTL specification, indicating superior leakage performance. Inventory availability is substantially higher than alternative substitutes. The operating temperature range of -55°C ~ 150°C applies the same lower bound limitation as the 40CTQ015.

Both substitute parts are suitable for direct replacement in applications where the minimum operating temperature requirement is -55°C or higher. Selection between the two substitutes depends on whether the additional 5 V reverse voltage margin and lower leakage current of the VS-47CTQ020-M3 are required for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 40CTQ015 be used as a direct replacement for the MBR4015CTL?

A: The 40CTQ015 is electrically compatible with the MBR4015CTL for applications operating at or above -55°C. Both parts share identical diode configuration, technology, current rating, and reverse voltage specification. The TO-220-3 package is identical, enabling direct mechanical substitution. The forward voltage of the 40CTQ015 is lower, which may improve circuit efficiency.

Q: What is the primary difference between the 40CTQ015 and VS-47CTQ020-M3?

A: The VS-47CTQ020-M3 has a maximum reverse voltage rating of 20 V compared to 15 V for both the MBR4015CTL and 40CTQ015. The VS-47CTQ020-M3 also exhibits lower reverse leakage current (3 mA @ 20 V versus 10 mA @ 15 V for the MBR4015CTL). Both parts are functionally compatible as substitutes, with the VS-47CTQ020-M3 providing additional voltage margin and improved leakage characteristics.

Q: Are there temperature range limitations when using substitute parts?

A: Both substitute parts operate over the temperature range of -55°C ~ 150°C, which is narrower than the MBR4015CTL range of -65°C ~ 150°C at the lower bound. Applications requiring operation below -55°C cannot use these substitutes. Applications operating within -55°C ~ 150°C are fully compatible.

Q: Do the substitute parts meet current compliance standards?

A: Both the 40CTQ015 and VS-47CTQ020-M3 are ROHS3 compliant, whereas the MBR4015CTL is RoHS non-compliant. Both substitute parts are REACH affected or unaffected as specified. For applications requiring RoHS compliance, either substitute part is suitable.

Q: Is the TO-220-3 package identical across all three parts?

A: Yes. The MBR4015CTL, 40CTQ015, and VS-47CTQ020-M3 all use the TO-220-3 package for through-hole mounting. Mechanical compatibility is confirmed, and no PCB layout modifications are required for substitution.

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

A: Selection depends on application-specific requirements. The 40CTQ015 is suitable for applications requiring exact voltage specification matching (15 V). The VS-47CTQ020-M3 is suitable for applications where additional voltage margin (20 V rating) and lower leakage current provide design benefits. Both parts are active products with confirmed availability.
