Engineering Selection Recommendations

STPS3030CR (Primary Substitute)

The STPS3030CR is the recommended substitute for the 32CTQ030-1. This part maintains electrical equivalence across all critical parameters: 30 V reverse voltage rating, 15 A average rectified current per diode, 490 mV forward voltage at 15 A, and fast recovery characteristics. The component is housed in the identical TO-262-3 Long Leads I2PAK package, ensuring mechanical compatibility with existing designs.

The STPS3030CR holds Active product status, providing long-term supply chain availability. The part is ROHS3 compliant, meeting current environmental and regulatory requirements. Current reverse leakage is 1 mA at 30 V, which is lower than the original 32CTQ030-1 specification of 1.75 mA, representing improved performance characteristics.

STPS30L30CR (Secondary Substitute)

The STPS30L30CR is an alternative substitute that meets all electrical and mechanical compatibility requirements. This part shares the same 30 V reverse voltage, 15 A current rating, fast recovery speed, and TO-262-3 I2PAK package configuration. The forward voltage specification is 460 mV at 15 A, which is lower than the 32CTQ030-1 at 490 mV, indicating superior forward conduction characteristics.

The STPS30L30CR is classified as Obsolete and carries ROHS3 compliance. While this part is electrically and mechanically equivalent, the STPS3030CR is preferred due to its Active product status and superior long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the STPS3030CR be used as a direct replacement for the 32CTQ030-1?

A: Yes. The STPS3030CR is electrically and mechanically equivalent to the 32CTQ030-1. Both components feature identical diode configuration, voltage rating, current rating, package type, and mounting method. No circuit modifications are required for substitution.

Q: What is the difference between the STPS3030CR and STPS30L30CR?

A: Both parts are electrically and mechanically compatible with the 32CTQ030-1. The primary difference is product status: STPS3030CR is Active, while STPS30L30CR is Obsolete. The STPS30L30CR exhibits a lower forward voltage specification (460 mV versus 490 mV at 15 A). For new designs and ongoing production, STPS3030CR is the preferred choice due to supply availability.

Q: Are there any compliance differences between the original part and the substitutes?

A: Yes. The 32CTQ030-1 is RoHS non-compliant, while both STPS3030CR and STPS30L30CR are ROHS3 compliant. If your application requires RoHS compliance, either STMicroelectronics substitute meets this requirement. All three parts are REACH Unaffected and carry EAR99 ECCN classification.

Q: Will the substitutes fit in the same circuit board footprint?

A: Yes. All three parts use the TO-262-3 Long Leads I2PAK TO-262AA package. The mechanical dimensions and pin configuration are identical, ensuring compatibility with existing printed circuit board layouts and assembly processes.

Q: What is the operating temperature range for the substitute parts?

A: The STPS3030CR and STPS30L30CR specify a maximum junction temperature of 150°C. The original 32CTQ030-1 specifies an operating range of -55°C to 150°C. For applications requiring operation below -55°C, design verification is necessary to confirm substitute part suitability.

Q: How do the reverse leakage characteristics compare?

A: The STPS3030CR exhibits 1 mA reverse leakage at 30 V, which is lower than the 32CTQ030-1 at 1.75 mA. The STPS30L30CR exhibits 1.5 mA reverse leakage at 30 V. Lower reverse leakage represents improved performance and reduced power dissipation in standby conditions.

Q: Are moisture sensitivity levels equivalent across all three parts?

A: Yes. The 32CTQ030-1, STPS3030CR, and STPS30L30CR all carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
