Substitute Part Grouping Explanation

Substitution of the ES2FHE3/5BT is determined by the following critical parameters: maximum reverse voltage (300 V), average rectified current (2 A), forward voltage drop (1.1 V @ 2 A), reverse recovery time (50 ns), reverse leakage current (10 µA @ 300 V), and surface mount DO-214AA (SMB) package compatibility. All substitute parts must maintain these electrical specifications and physical package dimensions to ensure functional equivalence in circuit applications.

Substitute parts are grouped into three categories:

Direct Manufacturer Equivalents (Vishay): Parts ES2FHE3_A/I, ES2F-M3/52T, ES2F-M3/5BT, and ES2FHE3_A/H maintain identical electrical ratings and automotive qualification. These parts differ primarily in packaging format (Tape & Reel versus bulk) and minor variations in reverse recovery time (35 ns versus 50 ns) or reverse leakage measurement conditions.

Parametric Equivalent (Vishay): Part ES2GHE3_A/H provides identical electrical performance with the same 35 ns reverse recovery time and automotive qualification, available in Cut Tape packaging.

Cross-Manufacturer Equivalent (onsemi): Part MURS230T3G from onsemi meets the core electrical requirements (300 V, 2 A, DO-214AA package) with minor parameter variations including higher forward voltage (1.3 V @ 2 A) and longer reverse recovery time (65 ns). This part carries Last Time Buy status.

Engineering Selection Recommendations

For Automotive Applications with AEC-Q101 Requirement:

Select ES2FHE3_A/I, ES2FHE3_A/H, or ES2GHE3_A/H. These Vishay parts maintain full automotive qualification and AEC-Q101 certification. ES2GHE3_A/H offers the highest inventory availability (17,545 pcs) and is recommended for high-volume production. ES2FHE3_A/H and ES2FHE3_A/I provide equivalent performance with slightly improved reverse recovery time (35 ns versus 50 ns of the original part).

For Non-Automotive or Legacy System Replacement:

ES2F-M3/52T and ES2F-M3/5BT are suitable alternatives when automotive qualification is not required. Both maintain identical electrical specifications to the original ES2FHE3/5BT, including 50 ns reverse recovery time and 10 µA reverse leakage at 300 V.

For Cross-Manufacturer Substitution:

MURS230T3G from onsemi provides functional equivalence in voltage and current ratings with identical DO-214AA package compatibility. However, this part carries Last Time Buy status and exhibits higher forward voltage drop (1.3 V versus 1.1 V) and longer reverse recovery time (65 ns versus 50 ns). Use only when Vishay alternatives are unavailable and circuit design accommodates the parameter variations.

Packaging Considerations:

Tape & Reel (TR) packaging is standard for production environments. Cut Tape (CT) packaging (ES2GHE3_A/H) is suitable for smaller quantity requirements or mixed component kitting. Bulk packaging is no longer available for active parts.

Frequently Asked Questions (FAQ)

Q: Can ES2FHE3_A/I directly replace ES2FHE3/5BT in production?

A: Yes. ES2FHE3_A/I is a direct manufacturer equivalent with identical electrical specifications (300 V, 2 A, 1.1 V forward voltage, 50 ns reverse recovery time) and automotive AEC-Q101 qualification. The primary difference is packaging format (Tape & Reel versus bulk). Functional performance in circuit is equivalent.

Q: What is the difference between ES2FHE3_A/H and ES2FHE3_A/I?

A: Both parts are Vishay automotive-qualified diodes with identical voltage and current ratings. ES2FHE3_A/H features 35 ns reverse recovery time compared to 50 ns for ES2FHE3_A/I. The reverse leakage current measurement condition differs (10 µA @ 50 V for ES2FHE3_A/H versus 10 µA @ 300 V for ES2FHE3_A/I). Both are suitable substitutes; ES2FHE3_A/H offers faster switching characteristics.

Q: Is ES2GHE3_A/H suitable for automotive applications?

A: Yes. ES2GHE3_A/H carries automotive grade designation and AEC-Q101 qualification identical to the original part. It is available in Cut Tape packaging and offers the highest inventory availability (17,545 pcs). Electrical performance is equivalent to ES2FHE3_A/H with 35 ns reverse recovery time.

Q: Can MURS230T3G replace ES2FHE3/5BT?

A: MURS230T3G meets the core voltage (300 V) and current (2 A) requirements with identical DO-214AA package. However, it exhibits higher forward voltage drop (1.3 V versus 1.1 V @ 2 A) and longer reverse recovery time (65 ns versus 50 ns). Use only when Vishay alternatives are unavailable and circuit design accommodates these parameter variations. This part is in Last Time Buy status.

Q: What is the significance of the reverse recovery time difference between 35 ns and 50 ns?

A: Reverse recovery time affects switching speed and switching losses in high-frequency applications. The 35 ns variants (ES2FHE3_A/H, ES2FHE3_A/I, ES2GHE3_A/H) provide faster switching compared to the original 50 ns specification. For most general-purpose rectification applications, both are functionally equivalent. High-frequency switching circuits may benefit from the faster 35 ns variants.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (ES2FHE3_A/I, ES2F-M3/52T, ES2F-M3/5BT, ES2FHE3_A/H, ES2GHE3_A/H, and MURS230T3G) are RoHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What packaging format should be selected for production?

A: Tape & Reel (TR) packaging is standard for automated assembly and production environments. Cut Tape (CT) packaging is suitable for manual assembly or small quantity requirements. All active substitute parts are available in Tape & Reel format except ES2GHE3_A/H, which is available in Cut Tape.

Q: Why is MURS230T3G marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer (onsemi) is discontinuing this part. Existing inventory may be available, but no future production is planned. For new designs or long-term production requirements, select active Vishay alternatives (ES2FHE3_A/I, ES2FHE3_A/H, ES2GHE3_A/H, ES2F-M3/52T, or ES2F-M3/5BT).
