Equivalent & Substitute Parts for 10ETF02S

Part Overview

The 10ETF02S is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 200 V DC reverse voltage and 10 A average rectified current in a surface mount TO-263AB (D2PAK) package. This part is classified as obsolete, making identification of active equivalent and substitute components essential for ongoing production and design continuity. The fast recovery characteristic (≤500 ns) and 145 ns reverse recovery time support applications requiring rapid switching performance. Equivalent parts are available from Vishay in active product status, while cross-manufacturer alternatives from STMicroelectronics provide additional sourcing options.

Substitute Part Grouping Explanation

Substitution of the 10ETF02S is determined by the following critical parameters:

Electrical Parameters (Must Match or Exceed):

Voltage - DC Reverse (Vr) (Max): 200 V minimum
Current - Average Rectified (Io): 10 A minimum
Voltage - Forward (Vf) (Max) @ If: 1.2 V or lower at rated current
Speed Classification: Fast Recovery ≤500 ns, >200 mA (Io)
Operating Temperature - Junction: -40°C to 150°C minimum range

Mechanical Parameters (Must Match):

Mounting Type: Surface Mount
Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB

Compliance Parameters:

RoHS Status: Preference for active RoHS3 compliant alternatives
Product Status: Active status preferred for long-term availability

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents (Vishay 10ETF02 Series) VS-10ETF02STRL-M3 and VS-10ETF02STRR-M3 are direct parametric equivalents from the same manufacturer base product line. These parts maintain identical electrical ratings and package specifications while offering active product status and RoHS3 compliance. The primary difference is packaging format (Tape & Reel) and minor variations in reverse recovery time (200 ns vs. 145 ns).

Category 2: Cross-Manufacturer Alternatives (STMicroelectronics) STTH1002CG-TR and STTH2002G-TR are cross-manufacturer alternatives that satisfy the core voltage and package requirements but differ in current rating and configuration. STTH1002CG-TR is a diode array (1 Pair Common Cathode) with 8 A per diode rating, while STTH2002G-TR is a single diode with 20 A rating. Both meet the 200 V reverse voltage requirement and TO-263AB package specification.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

VS-10ETF02STRL-M3 and VS-10ETF02STRR-M3 are the primary recommended substitutes for the obsolete 10ETF02S. Both parts maintain identical electrical specifications (200 V, 10 A, 1.2 V forward voltage) and package configuration. The transition from obsolete to active product status ensures long-term component availability and supply chain continuity. Both alternatives are ROHS3 compliant, addressing regulatory requirements that the original part does not meet. The reverse recovery time increase from 145 ns to 200 ns remains within the fast recovery classification and does not alter the functional performance category. These parts are available in Tape & Reel packaging, which is standard for production environments.

For Current Derating Applications:

STTH1002CG-TR is suitable for applications where the 10 A requirement can be met through parallel configuration or where the 8 A per-diode rating is acceptable. This part is a diode array with common cathode configuration, requiring circuit design consideration. The significantly lower reverse recovery time (25 ns) and reverse leakage current (5 µA) provide improved switching performance and lower standby losses compared to the original part.

For Current Upgrading Applications:

STTH2002G-TR is suitable for applications requiring higher current capacity. The 20 A rating provides design margin and allows for thermal derating in high-ambient-temperature environments. The 40 ns reverse recovery time and 10 µA reverse leakage current represent performance improvements over the original specification. The higher maximum junction temperature (175°C vs. 150°C) extends the operating envelope.

Compliance Consideration:

All recommended substitutes are ROHS3 compliant and REACH unaffected, supporting modern manufacturing and environmental standards. The original 10ETF02S is RoHS non-compliant and should be phased out in favor of compliant alternatives.

Frequently Asked Questions (FAQ)

Q: Can VS-10ETF02STRL-M3 or VS-10ETF02STRR-M3 be used as direct drop-in replacements for 10ETF02S?

A: Yes. Both parts are parametric equivalents with identical voltage (200 V), current (10 A), forward voltage (1.2 V @ 10 A), and package specifications (TO-263AB D2PAK). The reverse recovery time difference (200 ns vs. 145 ns) does not affect functional compatibility, as both remain within the fast recovery classification. The primary difference is packaging format (Tape & Reel vs. bulk) and active product status.

Q: What is the difference between VS-10ETF02STRL-M3 and VS-10ETF02STRR-M3?

A: Both parts are electrically identical with 200 V reverse voltage, 10 A current rating, and 200 ns reverse recovery time. The designations STRL and STRR indicate different internal configurations or manufacturing processes within the Vishay 10ETF02 product line. Both are active products with ROHS3 compliance and identical electrical performance.

Q: Why is STTH1002CG-TR listed as a substitute if it has only 8 A rating?

A: STTH1002CG-TR is a cross-manufacturer alternative that meets the core voltage requirement (200 V) and package specification (TO-263AB). However, it is a diode array with 1 Pair Common Cathode configuration and 8 A per-diode rating. This part is suitable for applications where the circuit topology can accommodate the array configuration or where 8 A per diode is sufficient. It is not a direct replacement for single-diode 10 A applications.

Q: Can STTH2002G-TR be used in place of 10ETF02S?

A: STTH2002G-TR meets the voltage (200 V) and package (TO-263AB) requirements and exceeds the current rating (20 A vs. 10 A). It is electrically compatible and provides design margin for thermal derating. However, it is not a direct drop-in replacement due to the higher current rating and different manufacturer. Circuit validation is necessary to confirm performance equivalence in the specific application.

Q: What is the significance of the reverse recovery time difference between 10ETF02S (145 ns) and the Vishay substitutes (200 ns)?

A: Both specifications fall within the fast recovery classification (≤500 ns, >200 mA). The 55 ns difference does not change the functional performance category. Applications sensitive to switching speed should evaluate the specific circuit requirements, but for general-purpose rectification, this difference is not significant.

Q: Are all substitute parts RoHS compliant?

A: Yes. VS-10ETF02STRL-M3, VS-10ETF02STRR-M3, STTH1002CG-TR, and STTH2002G-TR are all ROHS3 compliant. The original 10ETF02S is RoHS non-compliant. Transition to compliant alternatives is necessary for modern manufacturing environments and regulatory compliance.

Q: What is the difference between Tape & Reel packaging and bulk packaging?

A: Tape & Reel (TR) packaging is the standard format for automated assembly and production environments. All substitute parts are supplied in Tape & Reel format. The original 10ETF02S was available in bulk format. Tape & Reel packaging is compatible with standard pick-and-place equipment and is the industry standard for surface mount components.

Q: Can multiple STTH1002CG-TR diodes be paralleled to achieve 10 A capacity?

A: STTH1002CG-TR is a diode array with common cathode configuration, not individual diodes. Parallel connection of array elements requires specific circuit design consideration and is not a standard substitution approach. For 10 A single-diode applications, VS-10ETF02STRL-M3 or VS-10ETF02STRR-M3 are the appropriate choices.

Q: What is the maximum junction temperature difference between 10ETF02S and the STMicroelectronics substitutes?

A: The original 10ETF02S has a maximum junction temperature of 150°C. STTH1002CG-TR and STTH2002G-TR have maximum junction temperatures of 175°C. This 25°C difference allows for improved thermal derating in high-ambient-temperature applications when using STMicroelectronics alternatives.

Q: Are there any circuit design changes required when substituting 10ETF02S with STTH2002G-TR?

A: STTH2002G-TR is electrically compatible with 10ETF02S in terms of voltage rating and package. The higher current rating (20 A vs. 10 A) does not require circuit modifications; it provides design margin. However, thermal management and PCB layout should be evaluated to ensure the higher current capability does not introduce thermal issues in the specific application.
