STPSC10C065RY Equivalent & Substitute Parts

Part Overview

The STPSC10C065RY is a silicon carbide Schottky diode rated for 650 V DC reverse voltage and 10 A average rectified current, packaged in a through-hole I2PAK (TO-262-3 Long Leads) configuration. This component is classified as obsolete, indicating that direct procurement from original inventory may become limited. The substitute part STPSC10065DY provides equivalent electrical performance while offering active product status and alternative packaging in TO-220AC format, ensuring continued design support and supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPSC10C065RY with the STPSC10065DY is valid based on the following electrical and mechanical equivalence criteria:

Electrical Equivalence:

• Identical DC reverse voltage rating: 650 V
• Identical average rectified current: 10 A
• Identical technology platform: SiC (Silicon Carbide) Schottky
• Identical reverse recovery time: 0 ns
• Identical junction temperature range: -40°C to 175°C

Compliance & Certification Equivalence:

• Both devices maintain Automotive grade classification
• Both devices hold AEC-Q101 qualification
• Both devices comply with ROHS3 and REACH requirements
• Both devices feature MSL 1 (Unlimited) moisture sensitivity

Packaging Difference: The primary distinction between these parts is the package format. The STPSC10C065RY uses I2PAK (TO-262-3 Long Leads), while the STPSC10065DY uses TO-220AC. Both are through-hole mounting configurations suitable for PCB integration with appropriate footprint redesign.

Engineering Selection Recommendations

Primary Recommendation: STPSC10065DY

The STPSC10065DY is the manufacturer-recommended substitute for the obsolete STPSC10C065RY. Selection of this substitute is justified on the following engineering grounds:

1. Product Status Continuity: The STPSC10065DY maintains active product status, ensuring long-term availability, technical support, and supply chain stability compared to the obsolete STPSC10C065RY.

2. Electrical Equivalence: All critical electrical parameters—reverse voltage, forward current, recovery time, and temperature range—are identical between the two devices, confirming functional interchangeability in circuit operation.

3. Compliance Maintenance: Both devices retain identical automotive-grade classification and AEC-Q101 qualification, preserving compliance requirements for automotive and industrial applications.

4. Packaging Consideration: The transition from I2PAK to TO-220AC packaging requires PCB footprint modification. The TO-220AC package offers standard through-hole mounting with widely available socket and heatsink solutions.

5. Environmental Compliance: Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across manufacturing jurisdictions.

Frequently Asked Questions (FAQ)

Q: Can the STPSC10065DY directly replace the STPSC10C065RY without circuit modification?

A: Electrical substitution is direct. However, PCB layout modification is required due to package format differences. The STPSC10C065RY uses I2PAK (TO-262-3 Long Leads), while the STPSC10065DY uses TO-220AC. Pin-to-pin electrical connections remain identical; only the physical footprint and mounting hole pattern differ.

Q: Are there thermal performance differences between the I2PAK and TO-220AC packages?

A: Thermal performance characteristics are not provided in the supplied technical parameters. Package selection should be based on available PCB real estate, heatsinking requirements, and mechanical constraints specific to the application.

Q: Does the obsolete status of the STPSC10C065RY affect its electrical performance?

A: No. Obsolete status indicates end-of-life production and limited inventory availability, not degraded performance. Existing stock of the STPSC10C065RY remains electrically and functionally equivalent to the active STPSC10065DY.

Q: Are both devices suitable for automotive applications?

A: Yes. Both the STPSC10C065RY and STPSC10065DY carry automotive-grade classification and AEC-Q101 qualification, confirming suitability for automotive circuit applications.

Q: What is the primary reason to transition from STPSC10C065RY to STPSC10065DY?

A: The primary reason is supply chain continuity. The STPSC10C065RY is obsolete with finite inventory, while the STPSC10065DY is an active product with ongoing manufacturing support and availability.

Q: Are there any electrical parameter differences between the two devices?

A: All critical electrical parameters—voltage rating, current rating, recovery time, and temperature range—are identical. Minor differences in reverse leakage current (100 µA vs. 130 µA @ 650 V) and junction capacitance (480 pF vs. 670 pF @ 0V, 1MHz) are within normal manufacturing tolerance ranges and do not affect functional equivalence.
