Substitute Part Grouping Explanation

Substitution of the 10CTQ150STRR is determined by the following critical parameters: diode configuration (1 pair common cathode), technology (Schottky), package type (TO-263-3 D2PAK), voltage rating (150 V minimum), and current rating (5 A minimum per diode). Parts are grouped into two categories based on substitution relationship:

Category 1: Parametric Equivalent Parts that match all electrical and mechanical specifications of the original device, including identical voltage and current ratings, forward voltage characteristics, and package configuration.

Category 2: Manufacturer Recommended Substitutes Parts that meet or exceed the electrical specifications of the original device while offering improved performance characteristics such as lower reverse leakage current, active product status, or higher voltage/current ratings. These parts maintain identical package configuration and diode topology.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent): The 10CTQ150S is a parametric equivalent manufactured by Vishay with identical electrical specifications and package configuration. However, this part is also classified as obsolete. Selection of this part is appropriate only when existing inventory is available and long-term procurement is not a concern.

For Active Product Substitution: The STPS10150CG-TR manufactured by STMicroelectronics is the primary recommended substitute. This part maintains identical voltage (150 V) and current (5 A) ratings, identical package configuration (TO-263-3 D2PAK), and identical diode topology (1 pair common cathode). The STPS10150CG-TR offers improved performance with lower reverse leakage current (2 µA versus 50 µA) and holds active product status with ROHS3 compliance. This part is suitable for direct replacement in new designs and ongoing production.

For Higher Voltage Applications: The STPS10170CG-TR provides a 170 V reverse voltage rating while maintaining 5 A current capacity and identical package configuration. This part is appropriate for applications requiring higher voltage margin or operating in elevated voltage environments.

For Higher Current Applications: The STPS20150CG-TR provides 10 A average rectified current per diode while maintaining 150 V reverse voltage rating and identical package configuration. This part is appropriate for applications requiring higher current capacity or thermal margin.

All STMicroelectronics substitutes are active products with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the STPS10150CG-TR be used as a direct replacement for the 10CTQ150STRR? A: Yes. The STPS10150CG-TR maintains identical voltage (150 V), current (5 A), diode configuration (1 pair common cathode), technology (Schottky), and package (TO-263-3 D2PAK). The part is pin-compatible and electrically interchangeable. The STPS10150CG-TR offers improved reverse leakage characteristics and active product status.

Q: What is the difference between the STPS10150CG-TR and STPS10170CG-TR? A: The primary difference is the maximum reverse voltage rating. The STPS10150CG-TR is rated for 150 V, while the STPS10170CG-TR is rated for 170 V. Both maintain 5 A current capacity and identical package configuration. The STPS10170CG-TR is suitable for applications requiring higher voltage margin.

Q: What is the difference between the STPS10150CG-TR and STPS20150CG-TR? A: The primary difference is the maximum average rectified current per diode. The STPS10150CG-TR is rated for 5 A, while the STPS20150CG-TR is rated for 10 A. Both maintain 150 V voltage rating and identical package configuration. The STPS20150CG-TR is suitable for applications requiring higher current capacity.

Q: Is the 10CTQ150S a suitable substitute? A: The 10CTQ150S is a parametric equivalent with identical electrical specifications. However, both the 10CTQ150S and 10CTQ150STRR are classified as obsolete. This part is suitable only when existing inventory is available. For new designs and ongoing production, active products such as the STPS10150CG-TR are recommended.

Q: Are all substitute parts RoHS compliant? A: The original 10CTQ150STRR is RoHS non-compliant. The parametric equivalent 10CTQ150S is also RoHS non-compliant. All STMicroelectronics substitutes (STPS10150CG-TR, STPS10170CG-TR, STPS20150CG-TR) are ROHS3 compliant.

Q: Do all substitute parts use the same package configuration? A: Yes. All substitute parts use the TO-263-3 D2PAK (2 Leads + Tab) surface mount package, ensuring mechanical and electrical compatibility with the original 10CTQ150STRR.

Q: What is the reverse leakage current difference between the original part and substitutes? A: The 10CTQ150STRR has reverse leakage current of 50 µA @ 150 V. The STPS10150CG-TR reduces this to 2 µA @ 150 V, the STPS10170CG-TR to 10 µA @ 170 V, and the STPS20150CG-TR to 5 µA @ 150 V. Lower reverse leakage current improves device efficiency and reduces power dissipation.
