MBRB2060CT Equivalent & Substitute Parts

Part Overview

The MBRB2060CT is a Schottky diode array manufactured by Littelfuse Inc., configured as 1 pair common cathode with a maximum reverse voltage of 60 V and average rectified current of 10 A per diode. The device is packaged in TO-263-3 (D2PAK) surface mount configuration and is currently in active product status with 2395 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for higher current ratings or improved electrical characteristics within the same voltage class and package family.

Substitute Part Grouping Explanation

Substitution of the MBRB2060CT is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Diode configuration must remain 1 pair common cathode
Technology must be Schottky
Maximum reverse voltage (Vr) must be 60 V
Package must be TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
Mounting type must be surface mount
RoHS3 compliance required
MSL rating of 1 (Unlimited) required

Allowable Variation Parameters:

Current rating (Io) may be equal to or greater than 10 A
Forward voltage (Vf) may be lower than 800 mV
Reverse leakage current may be lower than 1 mA
Operating temperature range may be extended
Packaging format (Tape & Reel, Cut Tape, Tube) may vary
Product status may differ (Active, Last Time Buy)

Substitute parts are grouped into three categories based on current rating: 10 A equivalents, 15 A upgrades, and 20 A upgrades. All substitute parts maintain the 60 V reverse voltage specification and TO-263-3 package footprint.

Engineering Selection Recommendations

Direct Equivalents (10 A Rating):

STPS20L60CG-TR and STPS20L60CGY-TR are direct current-rated equivalents to the MBRB2060CT. Both devices maintain the 10 A average rectified current specification and 60 V reverse voltage. STPS20L60CG-TR is suitable for standard industrial applications with a maximum junction temperature of 150°C. STPS20L60CGY-TR includes automotive-grade qualification (AEC-Q101) and extended operating temperature range (-40°C to 175°C), making it appropriate for automotive and high-reliability applications.

Higher Current Alternatives (15 A Rating):

STPS30H60CG-TR, STPS30H60CGY-TR, STPS30L60CG-TR, MBRB2560CT-E3/81, VBT30L60C-E3/4W, VS-30CTQ060S-M3, and VS-30CTQ060STRL-M3 all provide 15 A current capacity. These parts are suitable for designs where the MBRB2060CT current rating is insufficient or where thermal margin is required. STPS30H60CGY-TR offers automotive qualification and extended temperature range. STPS30L60CG-TR provides the lowest forward voltage (600 mV @ 15 A) among 15 A options. MBRB2560CT-E3/81 is designated Last Time Buy status and should be selected only when inventory continuity is critical.

Higher Current Alternative (20 A Rating):

STPS41L60CG-TR provides 20 A average rectified current in the same TO-263-3 package. This part is suitable for applications requiring significant thermal headroom or where current derating is necessary. Inventory availability is substantial (800,100 units).

Packaging Considerations:

All substitute parts maintain TO-263-3 (D2PAK) footprint compatibility. Packaging format variations (Tape & Reel, Cut Tape, Tube) do not affect electrical performance or PCB mounting. Selection should be based on assembly process requirements and supply chain availability.

Product Status:

All recommended substitutes except MBRB2560CT-E3/81 maintain Active product status. MBRB2560CT-E3/81 is Last Time Buy and should be avoided for new designs unless existing inventory commitments require its use.

Frequently Asked Questions (FAQ)

Q: Can STPS20L60CG-TR be used as a direct replacement for MBRB2060CT?

A: Yes. STPS20L60CG-TR is a direct current-rated equivalent with identical 10 A average rectified current and 60 V reverse voltage. The device is packaged in the same TO-263-3 (D2PAK) configuration and is pin-compatible. Forward voltage is lower (600 mV vs. 800 mV @ 10 A), which reduces power dissipation.

Q: What is the difference between STPS30H60CG-TR and STPS30L60CG-TR?

A: Both devices provide 15 A current capacity and 60 V reverse voltage in TO-263-3 packaging. STPS30H60CG-TR has a maximum junction temperature of 175°C and reverse leakage of 60 µA @ 60 V. STPS30L60CG-TR has a maximum junction temperature of 150°C and reverse leakage of 480 µA @ 60 V. STPS30H60CG-TR is preferred for high-temperature applications.

Q: Is STPS20L60CGY-TR suitable for automotive applications?

A: Yes. STPS20L60CGY-TR carries AEC-Q101 automotive qualification and operates across -40°C to 175°C, meeting automotive temperature and reliability requirements. It maintains 10 A current capacity and 60 V reverse voltage.

Q: Can a 15 A rated part replace a 10 A rated part?

A: Yes. A 15 A rated device can replace a 10 A rated device when both maintain the same 60 V reverse voltage and TO-263-3 package. The higher current rating provides additional thermal margin and does not affect circuit operation at 10 A load current.

Q: What is the significance of the "Y" suffix in STPS20L60CGY-TR and STPS30H60CGY-TR?

A: The "Y" suffix indicates automotive-grade qualification (AEC-Q101) and extended operating temperature range. These parts are qualified for automotive applications and high-reliability environments.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain RoHS3 compliance and MSL rating of 1 (Unlimited), matching the MBRB2060CT environmental and handling specifications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel and Cut Tape are packaging formats for surface mount components. Both formats contain identical devices in TO-263-3 (D2PAK) packages. Selection depends on assembly equipment compatibility and supply chain preference. Electrical performance is identical.

Q: Why is MBRB2560CT-E3/81 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued or will discontinue production. This part should be selected only when existing inventory commitments or long-term supply agreements require its use. For new designs, select Active status alternatives such as STPS30H60CGY-TR or STPS30L60CG-TR.

Q: Can STPS41L60CG-TR (20 A) be used in place of MBRB2060CT (10 A)?

A: Yes. STPS41L60CG-TR maintains 60 V reverse voltage and TO-263-3 packaging. The 20 A current rating provides significant thermal margin for 10 A applications. This substitution is appropriate when design specifications allow for higher current capacity or when thermal performance improvement is required.

Q: What is the impact of lower forward voltage in substitute parts?

A: Lower forward voltage reduces power dissipation and heat generation. STPS20L60CG-TR and STPS30L60CG-TR both specify 600 mV forward voltage compared to 800 mV in the MBRB2060CT. This 200 mV reduction decreases power loss and improves thermal performance without affecting circuit functionality.
