Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR50035CT is determined by the following critical parameters that must remain constant or be exceeded:

Fixed Parameters (Must Match Exactly):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 35 V
• Mounting Type: Chassis Mount
• Package / Case: Twin Tower
• Operating Temperature Range: -55°C ~ 150°C

Allowable Parameter Variance:

• Current - Average Rectified (Io) (per Diode): May be equal to or greater than 250 A
• Voltage - Forward (Vf) (Max) @ If: May be equal to or less than 750 mV
• Current - Reverse Leakage @ Vr: May be equal to or less than 1 mA @ 20 V

The MBR60035CT qualifies as a direct substitute because it maintains all fixed parameters while providing enhanced current capability (300 A versus 250 A), identical forward voltage characteristics, and equivalent reverse leakage performance.

Engineering Selection Recommendations

The MBR60035CT is a qualified substitute for the obsolete MBR50035CT based on the following engineering criteria:

Product Status Alignment: The MBR60035CT maintains Active product status, ensuring continued availability and manufacturer support, whereas the MBR50035CT is classified as Obsolete.

Compliance Certification: Both components maintain RoHS Compliant status and identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, ensuring regulatory and trade compliance equivalence.

Electrical Performance: The MBR60035CT provides enhanced current capacity (300 A versus 250 A per diode) while maintaining identical reverse voltage rating (35 V), forward voltage characteristics (750 mV), and reverse leakage performance (1 mA @ 20 V). This represents a performance upgrade with no degradation in any specified parameter.

Mechanical and Thermal Compatibility: Identical chassis mount Twin Tower packaging and operating temperature range (-55°C ~ 150°C) ensure direct mechanical and thermal interchangeability.

Supply Chain Availability: The MBR60035CT demonstrates significantly higher inventory availability (3680 Pcs versus 766 Pcs), supporting long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the MBR60035CT be used as a direct replacement for the MBR50035CT in existing designs?

A: Yes. The MBR60035CT is electrically and mechanically compatible with the MBR50035CT. All critical parameters match or exceed the original specification. The higher current rating (300 A versus 250 A) represents an enhancement with no performance degradation.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Current rating: MBR60035CT is rated for 300 A versus 250 A for the MBR50035CT; (2) Product Status: MBR60035CT is Active while MBR50035CT is Obsolete; (3) Inventory availability: MBR60035CT has significantly higher stock levels.

Q: Are the package dimensions identical between MBR50035CT and MBR60035CT?

A: Both components use the Twin Tower chassis mount package. The provided specifications confirm identical package classification and mounting type, ensuring mechanical interchangeability.

Q: Does the MBR60035CT maintain the same thermal characteristics?

A: Yes. Both components share identical operating temperature range (-55°C ~ 150°C) and are mounted via the same chassis mount configuration, ensuring equivalent thermal performance in circuit applications.
