Substitute Part Grouping Explanation

Substitute parts for the ES2FHE3_A/I are identified based on electrical and mechanical parameter equivalence. The critical parameters that determine substitutability are:

Voltage - DC Reverse (Vr) (Max): 300 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
Reverse Recovery Time (trr): 35 ns
Current - Reverse Leakage @ Vr: 10 µA @ 50 V
Capacitance @ Vr, F: 15 pF @ 4V, 1MHz
Operating Temperature - Junction: -55°C to 150°C
Package / Case: DO-214AA (SMB)
Mounting Type: Surface Mount
Grade: Automotive
Qualification: AEC-Q101

The ES2GHE3_A/H meets all electrical and mechanical parameter requirements for direct substitution. The primary difference between the main part and the substitute is the packaging format: the ES2FHE3_A/I is supplied in Tape & Reel (TR) format, while the ES2GHE3_A/H is supplied in Cut Tape (CT) format. Both parts share identical electrical characteristics, thermal ratings, compliance certifications, and mounting specifications.

Engineering Selection Recommendations

The ES2GHE3_A/H is a direct electrical and mechanical equivalent to the ES2FHE3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division, carry active product status, and maintain identical electrical performance specifications across all rated parameters. Both devices are AEC-Q101 qualified for automotive applications and are RoHS3 compliant with REACH unaffected status.

Selection between these parts is determined by packaging and supply chain requirements. The ES2FHE3_A/I in Tape & Reel format is suitable for high-volume automated assembly operations. The ES2GHE3_A/H in Cut Tape format accommodates lower-volume production runs or manual assembly processes. The ES2GHE3_A/H currently maintains higher inventory availability at 17545 units compared to 1070 units for the ES2FHE3_A/I.

Both parts are suitable for applications requiring 300 V reverse voltage rating, 2 A average rectified current, fast recovery characteristics, and automotive-grade reliability. No electrical performance trade-offs exist between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can the ES2GHE3_A/H be used as a direct replacement for the ES2FHE3_A/I in circuit design?

A: Yes. The ES2GHE3_A/H is electrically and mechanically equivalent to the ES2FHE3_A/I. All electrical parameters, thermal ratings, package dimensions, and mounting specifications are identical. The devices are interchangeable from a circuit performance perspective.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape packaging supplies components on tape segments, typically used for lower-volume assembly or manual placement. Both formats contain the same component in the same DO-214AA package.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the ES2FHE3_A/I and ES2GHE3_A/H carry AEC-Q101 automotive qualification and Automotive grade designation. Both are suitable for automotive circuit applications requiring this qualification level.

Q: Do these parts have identical thermal performance?

A: Yes. Both parts share identical operating temperature junction range of -55°C to 150°C and identical reverse recovery time of 35 ns. Thermal performance is equivalent.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). Compliance status is identical.

Q: Which part should be selected for new designs?

A: Selection is based on manufacturing process requirements. For high-volume automated assembly, the ES2FHE3_A/I Tape & Reel format is appropriate. For lower-volume or manual assembly processes, the ES2GHE3_A/H Cut Tape format is appropriate. Electrical performance is identical in both cases.
