Engineering Selection Recommendations

Direct Equivalent (Same Current Rating):

The MBRB2060CT from Littelfuse Inc. is a direct equivalent with identical part number designation. This part maintains the same 10 A current rating and 60 V voltage specification. The Littelfuse version is ROHS3 compliant and carries active product status, making it suitable for new designs and ongoing production support.

The STPS20L60CG-TR from STMicroelectronics provides equivalent electrical performance at the 10 A rating with improved forward voltage characteristics (600 mV @ 10 A versus 950 mV @ 20 A). This part is ROHS3 compliant and actively manufactured.

The SBR20A60CTB from Diodes Incorporated offers Super Barrier technology with superior forward voltage performance (650 mV @ 10 A) while maintaining the 10 A current rating. This part is ROHS3 compliant and actively produced.

Higher Current Capacity Alternatives:

The MBRB2060CT-TP from Micro Commercial Co provides 20 A current capacity in the same package, offering design margin for applications requiring higher current handling. This part maintains Schottky technology and fast recovery characteristics.

The STPS30L60CG-TR from STMicroelectronics provides 15 A capacity with improved forward voltage (600 mV @ 15 A). This part is ROHS3 compliant and actively manufactured.

The STPS41L60CG-TR from STMicroelectronics provides 20 A capacity with optimized forward voltage (600 mV @ 20 A). This part is ROHS3 compliant and actively manufactured with the highest inventory availability (800,100 pcs).

The SBR20A60CTBQ-13 from Diodes Incorporated provides 20 A capacity with automotive qualification (AEC-Q101). This part is ROHS3 compliant and actively produced.

Compliance Considerations:

All active substitute parts listed are ROHS3 compliant, addressing environmental regulatory requirements. The original onsemi MBRB2060CT is RoHS non-compliant. Selection of ROHS3 compliant alternatives is recommended for new designs and applications subject to environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the MBRB2060CT be directly replaced with the Littelfuse MBRB2060CT?

A: Yes. Both parts share identical part number designation, voltage rating (60 V), current rating (10 A), diode configuration (1 Pair Common Cathode), and package specification (TO-263-3 D2PAK). The Littelfuse version is ROHS3 compliant and actively manufactured, making it a direct replacement.

Q: What is the difference between Schottky and Super Barrier technology in these substitutes?

A: Both technologies are acceptable substitutes based on the provided parameters. Schottky diodes (STPS series, Littelfuse MBRB2060CT) and Super Barrier diodes (SBR series from Diodes Incorporated) both meet the 60 V voltage and 10 A current requirements. Super Barrier technology typically offers lower forward voltage characteristics. Selection depends on application-specific thermal and efficiency requirements.

Q: Can I use a higher current-rated part such as STPS41L60CG-TR (20 A) in place of the 10 A MBRB2060CT?

A: Yes. Higher current-rated parts are acceptable substitutes when the voltage rating (60 V), diode configuration (1 Pair Common Cathode), and package (TO-263-3 D2PAK) remain identical. The 20 A rated parts provide additional design margin and are pin-compatible. No circuit modifications are required.

Q: Are all substitute parts available in the same D2PAK package?

A: Yes. All substitute parts listed are specified for TO-263-3, D2PAK (2 Leads + Tab), TO-263AB package. This ensures mechanical and electrical compatibility with existing PCB layouts and solder reflow processes.

Q: What is the significance of the operating temperature range difference between the original and substitute parts?

A: The original onsemi MBRB2060CT specifies -65°C to 175°C junction temperature range. Most active substitutes specify -65°C to 150°C or 150°C maximum. For applications operating above 150°C, the original part specification must be verified. For standard industrial applications operating below 150°C, all listed substitutes are acceptable.

Q: Why is the original MBRB2060CT listed as obsolete?

A: Obsolescence is a product lifecycle status indicating the manufacturer has discontinued production. Active equivalent parts from Littelfuse Inc., STMicroelectronics, and Diodes Incorporated provide continued design support and procurement availability.

Q: What packaging options are available for these substitute parts?

A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, Tube, and Bulk. Selection depends on procurement volume and assembly process requirements. All packaging options contain identical die and electrical specifications.

Q: Is RoHS compliance a mandatory consideration for substitution?

A: RoHS compliance status is determined by application requirements and regulatory jurisdiction. All active substitute parts are ROHS3 compliant. The original onsemi part is RoHS non-compliant. For applications subject to environmental regulations or customer requirements, ROHS3 compliant alternatives are necessary.
