Substitute Part Grouping Explanation

Substitution of the MBRS360T3 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 60V minimum
Current - Average Rectified (Io): 3A minimum
Technology: Schottky
Mounting Type: Surface Mount
Package compatibility: DO-214AB (SMC) preferred for direct mechanical interchange

Secondary Compatibility Factors:

Voltage - Forward (Vf) (Max) @ If: ≤750 mV @ 3A
Speed: Fast Recovery ≤500ns, >200mA (Io)
Current - Reverse Leakage @ Vr: ≤500 µA @ 60V

Parts are grouped into two categories:

Direct Equivalents (Same Package - DO-214AB/SMC): Parts maintaining identical mechanical form factor and electrical specifications within tolerance.

Functional Equivalents (Alternative Packages): Parts meeting electrical requirements but utilizing different surface mount packages (DO-214AA/SMB, DO-214AC/SMA), requiring PCB layout modification.

Higher Current Rated Parts: Parts exceeding 3A rating (5A) that function as substitutes in applications where the MBRS360T3 operates below maximum current specification.

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Identical Package, Active Status):

MBRS360T3G (onsemi) is the primary direct equivalent. This part maintains identical electrical specifications (60V, 3A, 740mV forward voltage) and mechanical form factor (DO-214AB/SMC). The part is in active production status with ROHS3 compliance, addressing the obsolescence of the original MBRS360T3. This selection eliminates PCB redesign requirements.

STPS3L60S (STMicroelectronics) provides equivalent functionality in the same package with improved reverse leakage characteristics (55µA versus 150µA). Forward voltage is reduced to 700mV, resulting in lower power dissipation. Active production status and ROHS3 compliance support long-term availability.

VS-MBRS360-M3/9AT (Vishay General Semiconductor) offers identical electrical specifications to the original part in an active production status. ROHS3 compliance and DO-214AB/SMC packaging enable direct substitution without layout modification.

Tier 2 - Functional Equivalents (Alternative Packages, Active Status):

CDBB360-G (Comchip Technology) meets electrical requirements (60V, 3A) with reduced forward voltage (700mV). The DO-214AA/SMB package requires PCB layout modification but maintains surface mount technology. Active status and ROHS3 compliance support procurement continuity.

SS36 (MDD) provides 60V, 3A Schottky rectification in a DO-214AC/SMA package. This smaller package footprint requires PCB redesign. Active production status and ROHS3 compliance are confirmed.

Tier 3 - Higher Current Rated Substitute (Same Package):

CDBC560-G (Comchip Technology) is rated for 5A average rectified current while maintaining 60V reverse voltage and DO-214AB/SMC packaging. This part functions as a substitute in applications where the MBRS360T3 operates below 3A specification, providing design margin. Active status and ROHS3 compliance are confirmed.

Obsolete Parts (Not Recommended for New Designs):

SK36-TP (Micro Commercial Co) is classified as obsolete and should not be selected for new designs despite meeting electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can MBRS360T3G directly replace MBRS360T3 without PCB modification?

A: Yes. MBRS360T3G maintains identical electrical specifications (60V, 3A, 740mV forward voltage) and mechanical form factor (DO-214AB/SMC package). No PCB layout changes are required. The part is in active production with ROHS3 compliance.

Q: What is the difference between STPS3L60S and MBRS360T3?

A: Both parts are rated 60V, 3A Schottky diodes in DO-214AB/SMC packages. STPS3L60S exhibits lower reverse leakage (55µA versus 150µA) and reduced forward voltage (700mV versus 740mV), resulting in lower power dissipation. STPS3L60S is in active production with ROHS3 compliance.

Q: Can I use CDBB360-G as a substitute if my PCB layout permits package change?

A: Yes. CDBB360-G meets the electrical requirements (60V, 3A) with forward voltage of 700mV. The DO-214AA/SMB package is smaller than DO-214AB/SMC, requiring PCB footprint modification. The part is in active production with ROHS3 compliance.

Q: Why is CDBC560-G listed as a substitute if it is rated for 5A?

A: CDBC560-G functions as a substitute in applications where the MBRS360T3 operates below its 3A maximum specification. The higher current rating (5A) provides design margin and thermal headroom. The part maintains 60V reverse voltage and DO-214AB/SMC packaging. This selection is appropriate when application current requirements are confirmed below 3A.

Q: What is the impact of package differences between DO-214AB, DO-214AA, and DO-214AC?

A: DO-214AB (SMC) is the largest package, DO-214AA (SMB) is intermediate, and DO-214AC (SMA) is the smallest. These packages have different PCB footprints and thermal characteristics. Direct mechanical interchange requires identical package designation. Alternative packages necessitate PCB layout modification and thermal analysis.

Q: Should I select SK36-TP for new designs?

A: No. SK36-TP is classified as obsolete and should not be selected for new designs. Active production alternatives such as MBRS360T3G, STPS3L60S, or VS-MBRS360-M3/9AT are preferred to ensure long-term component availability.

Q: What does ROHS3 compliance mean for component selection?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. MBRS360T3 is non-compliant, while all listed active substitutes are ROHS3 compliant. This compliance is required for many applications and regulatory jurisdictions.

Q: How do reverse leakage specifications affect circuit performance?

A: Reverse leakage current flows when the diode is reverse-biased. Lower reverse leakage reduces standby power consumption and improves circuit efficiency. STPS3L60S exhibits 55µA reverse leakage compared to 150µA for MBRS360T3, providing improved performance in low-power applications.

Q: Can I use multiple lower-rated diodes in parallel to replace MBRS360T3?

A: Parallel diode configurations introduce current sharing complexity and are not recommended as direct substitutes. Single-device replacements from the provided substitute list are the appropriate engineering solution.
