Engineering Selection Recommendations

MBR1080CT (SMC Diode Solutions): The MBR1080CT is an Active product offering direct functional equivalence to the obsolete STPS10M80CT. Both devices share identical voltage ratings, configuration, and package specifications. The MBR1080CT maintains ROHS3 compliance and carries unlimited moisture sensitivity rating. This part is suitable for direct replacement in applications where the 5 A current specification of the original design is maintained. Current inventory availability is 2320 pieces.

DST2080C (Littelfuse Inc.): The DST2080C is an Active product with identical voltage and configuration specifications. This part features a 10 A average rectified current rating, providing increased current capacity relative to the STPS10M80CT. The DST2080C is suitable for applications requiring the same 80 V reverse voltage and Common Cathode configuration, with the capability to handle higher current loads. ROHS3 compliance and unlimited MSL rating are maintained. Current inventory availability is 1781 pieces.

DST3080C (Littelfuse Inc.): The DST3080C is an Active product with identical voltage and configuration specifications. This part features a 15 A average rectified current rating, providing the highest current capacity among the substitute options. The DST3080C is suitable for applications requiring the same 80 V reverse voltage and Common Cathode configuration, with capability to handle significantly higher current loads. ROHS3 compliance and unlimited MSL rating are maintained. Current inventory availability is 652 pieces.

Selection Basis: All substitute parts are Active products, eliminating obsolescence risk. Selection between MBR1080CT, DST2080C, and DST3080C depends on application current requirements. For designs operating at or below 5 A, MBR1080CT provides direct equivalence. For designs requiring higher current margins or future capacity expansion, DST2080C (10 A) or DST3080C (15 A) offer increased headroom within the same electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the MBR1080CT directly replace the STPS10M80CT in existing designs?

A: Yes. The MBR1080CT shares identical voltage rating (80 V), diode configuration (1 Pair Common Cathode), package type (TO-220-3), and mounting method (Through Hole) with the STPS10M80CT. Both devices are ROHS3 compliant with unlimited moisture sensitivity rating. Direct substitution is supported for applications operating within the 5 A current specification.

Q: What is the difference between the MBR1080CT, DST2080C, and DST3080C?

A: All three parts maintain identical 80 V reverse voltage rating and Common Cathode configuration. The primary difference is current capacity: MBR1080CT operates at 5 A (matching the original STPS10M80CT), DST2080C at 10 A, and DST3080C at 15 A. Forward voltage characteristics vary slightly across the three parts due to their different current ratings. All three are Active products with full ROHS3 compliance.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All substitute parts use the TO-220-3 package in Through Hole mounting configuration, identical to the STPS10M80CT. Mechanical fit and PCB layout compatibility are maintained across all substitutes. Supplier device package designations (TO-220 versus TO-220AB) reflect manufacturer nomenclature variations but do not affect physical compatibility.

Q: What is the significance of the different current ratings among substitute parts?

A: Current rating indicates the maximum average rectified current each diode can handle continuously. The STPS10M80CT is rated at 5 A per diode. Substitute parts with higher ratings (10 A or 15 A) can safely operate at the original 5 A specification with additional thermal margin. Selection of a higher-rated part does not require design changes but provides increased operational headroom and potential thermal benefits in demanding applications.

Q: Are all substitute parts compliant with the same regulatory standards as the STPS10M80CT?

A: Yes. All substitute parts maintain ROHS3 compliance, share the same ECCN classification (EAR99), and carry identical HTSUS codes (8541.10.0080). Moisture sensitivity level is 1 (Unlimited) for all parts. Regulatory equivalence is maintained across all substitutes.

Q: What is the current inventory status for each substitute part?

A: MBR1080CT: 2320 pieces in stock. DST2080C: 1781 pieces in stock. DST3080C: 652 pieces in stock. All parts are available as New Original stock.
