Substitute Part Grouping Explanation

Substitution of the ES2F-M3/5BT is determined by electrical and mechanical parameter equivalence within the rectifier diode category. The critical parameters that define substitutability are:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 300 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters:

Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount

Compliance Parameters:

RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

The ES2GHE3_A/H qualifies as a parametric equivalent because it maintains identical voltage, current, package, and mounting specifications. Differences in reverse recovery time (35 ns versus 50 ns) and reverse leakage measurement conditions represent performance enhancements rather than incompatibilities. The primary distinction is packaging format: ES2F-M3/5BT is supplied in Tape & Reel (TR) format, while ES2GHE3_A/H is supplied in Cut Tape (CT) format. Both parts share the same base electrical characteristics and compliance certifications.

Engineering Selection Recommendations

ES2F-M3/5BT Selection Criteria: The ES2F-M3/5BT is appropriate for applications requiring a general-purpose rectifier diode in Tape & Reel packaging format. This part maintains Active product status and full RoHS3 compliance. Selection of this part number is suitable when procurement specifications explicitly require TR packaging or when inventory systems are configured for reel-based component handling.

ES2GHE3_A/H Selection Criteria: The ES2GHE3_A/H qualifies as a direct substitute when Cut Tape packaging is acceptable or preferred. This part carries Automotive grade classification and AEC-Q101 qualification, indicating enhanced reliability screening and suitability for automotive applications. The improved reverse recovery time (35 ns versus 50 ns) provides superior switching performance characteristics. Selection of ES2GHE3_A/H is appropriate for applications where automotive-grade components are specified or where enhanced performance margins are required. Both parts maintain identical electrical ratings and full compliance certifications.

Substitution Feasibility: Substitution between ES2F-M3/5BT and ES2GHE3_A/H is electrically and mechanically valid. The primary consideration is packaging format compatibility with assembly and procurement infrastructure. Both parts are manufactured by the same supplier, share identical electrical specifications, and maintain equivalent compliance status.

Frequently Asked Questions (FAQ)

Q: Can ES2GHE3_A/H replace ES2F-M3/5BT in existing designs?

A: Yes. Both parts share identical voltage ratings (300 V), current ratings (2 A), forward voltage characteristics (1.1 V @ 2 A), and package form factor (DO-214AA, SMB). The primary difference is packaging format: ES2F-M3/5BT is supplied in Tape & Reel format, while ES2GHE3_A/H is supplied in Cut Tape format. Electrical substitution is valid; assembly process compatibility depends on equipment configuration.

Q: What is the difference in reverse recovery time between these parts?

A: The ES2F-M3/5BT specifies a reverse recovery time of 50 ns, while the ES2GHE3_A/H specifies 35 ns. Both parts meet the fast recovery classification (≤ 500 ns, > 200 mA). The shorter recovery time of ES2GHE3_A/H represents improved switching performance and reduced switching losses in high-frequency applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ES2F-M3/5BT and ES2GHE3_A/H are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Both parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the significance of the Automotive grade designation on ES2GHE3_A/H?

A: The ES2GHE3_A/H carries Automotive grade classification and AEC-Q101 qualification. This indicates the part has undergone enhanced reliability screening and qualification testing specific to automotive applications. Standard-grade parts like ES2F-M3/5BT do not carry this qualification. Selection of automotive-grade components is required when specifications mandate AEC-Q101 compliance.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Both parts are classified as fast recovery diodes and operate within identical voltage and current parameters. The ES2GHE3_A/H offers improved reverse recovery time (35 ns versus 50 ns), which provides superior performance in high-frequency switching applications. For applications with stringent switching speed requirements, ES2GHE3_A/H is the preferred selection.

Q: What packaging considerations apply when substituting between these parts?

A: ES2F-M3/5BT is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly from reel feeders. ES2GHE3_A/H is supplied in Cut Tape (CT) format, suitable for manual or semi-automated assembly processes. Substitution requires verification that assembly equipment and procurement workflows support the alternative packaging format.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts specify an operating temperature range of -55°C to 150°C (junction temperature). Thermal performance characteristics are equivalent across the specified operating range.
