Substitute Part Grouping Explanation

Substitution of the STPS10170CT is determined by the following critical parameters:

Configuration Match: The substitute part must maintain a 1 Pair Common Cathode diode array configuration to ensure pin-compatible operation within existing circuit designs.

Technology Consistency: Schottky diode technology must be preserved to maintain the fast recovery characteristics and forward voltage performance required by the application.

Electrical Ratings: The substitute part must meet or exceed the voltage and current specifications of the original component. The STPS10170CT operates at 170 V maximum reverse voltage with 5 A average rectified current. Substitute parts with higher voltage and current ratings remain functionally compatible within the original design envelope.

Package Compatibility: The TO-220-3 through-hole package is mandatory for mechanical and thermal compatibility with existing PCB layouts and mounting infrastructure.

Compliance Requirements: RoHS3 compliance and EAR99 export classification must be maintained to satisfy regulatory and supply chain requirements.

The MBR20200CTG from onsemi satisfies all substitution criteria with enhanced electrical performance characteristics.

Electrical Superiority: The MBR20200CTG provides enhanced performance margins with 200 V reverse voltage rating (versus 170 V) and 10 A current capacity (versus 5 A), ensuring the substitute operates within safe design margins when applied to circuits originally specified for the STPS10170CT.

Technology Alignment: Both components employ Schottky diode technology with identical fast recovery characteristics (≤ 500 ns), preserving switching performance and efficiency in rectification and protection applications.

Regulatory Compliance: The MBR20200CTG maintains ROHS3 compliance and EAR99 export classification, satisfying all regulatory requirements applicable to the original component.

Supply Availability: The MBR20200CTG is classified as Active with substantial inventory availability (55,160 pcs), providing reliable long-term supply continuity compared to the obsolete STPS10170CT.

Frequently Asked Questions (FAQ)

Q: Can the MBR20200CTG directly replace the STPS10170CT without circuit modifications?

A: Yes. Both components share identical TO-220-3 pinout configuration and 1 Pair Common Cathode diode array topology. Direct PCB-level substitution is supported without schematic or layout changes.

Q: What are the key differences between these components?

A: The MBR20200CTG provides higher voltage rating (200 V versus 170 V) and higher current capacity (10 A versus 5 A). Both maintain identical fast recovery characteristics and operating temperature limits. The MBR20200CTG is currently in active production, while the STPS10170CT is obsolete.

Q: Are there thermal considerations when substituting these parts?

A: Both components share identical maximum junction temperature ratings (175°C) and TO-220-3 package form factor. Thermal performance is equivalent when mounted using identical PCB layout and heatsinking configurations.

Q: Does the higher current rating of the MBR20200CTG affect circuit operation?

A: No. The higher current rating represents an increased capability margin. The substitute component operates safely within the original design's current requirements while providing additional headroom for design flexibility.

Q: Are both components RoHS compliant?

A: Yes. Both the STPS10170CT and MBR20200CTG are ROHS3 compliant and REACH unaffected, satisfying all applicable environmental and regulatory requirements.

Q: What is the reverse leakage current difference between these components?

A: The STPS10170CT specifies 10 µA @ 170 V, while the MBR20200CTG specifies 1 mA @ 200 V. This difference reflects measurement at different voltage levels and does not impact circuit functionality within the original design envelope.

Q: Can the MBR20200CTG be used in applications requiring the exact 170 V rating?

A: Yes. The MBR20200CTG's 200 V rating exceeds the 170 V requirement, providing additional voltage margin. The component operates safely in circuits designed for 170 V maximum reverse voltage.
