Engineering Selection Recommendations

Primary Recommendation: ES2HA

The ES2HA is a parametric equivalent to the ES2HA M2G with identical electrical specifications and package form factor. This part maintains active product status and is available in Tape & Reel packaging. The ES2HA provides direct functional replacement capability without circuit modification. ROHS3 compliance and MSL 1 rating match the original specification.

Secondary Recommendation: AES2HF-HF

The AES2HF-HF is a parametric equivalent manufactured by Comchip Technology, offering identical voltage, current, and recovery time specifications. This part features lower reverse leakage current (5 µA versus 10 µA) and carries AEC-Q101 automotive qualification. The AES2HF-HF is available in active product status with Tape & Reel packaging. Selection of this part is appropriate for applications requiring automotive-grade components or enhanced leakage performance.

Alternative Consideration: UFS150JE3/TR13

The UFS150JE3/TR13 manufactured by Microchip Technology shares the 500 V voltage rating and DO-214BA package compatibility but is rated for 1 A average rectified current. This part is suitable only for applications where the 2 A current requirement can be reduced or where parallel configurations are implemented. The extended operating temperature range (-55°C to 175°C) provides additional thermal margin. This part carries active product status.

Discontinued Part: ES2HA R3G

The ES2HA R3G is a parametric equivalent with identical electrical specifications but is discontinued at DiGi Electronics. This part should not be selected for new designs or long-term procurement strategies.

Frequently Asked Questions (FAQ)

Q: Can the ES2HA directly replace the ES2HA M2G?

A: Yes. The ES2HA is a parametric equivalent with identical voltage rating (500 V), current rating (2 A), forward voltage drop (1.7 V @ 2 A), reverse recovery time (35 ns), and package form factor (DO-214AC, SMA). The primary difference is packaging format (Tape & Reel versus unspecified) and active product status. No circuit redesign is required.

Q: What is the difference between ES2HA M2G and ES2HA R3G?

A: Both parts are parametric equivalents with identical electrical specifications. The ES2HA R3G is supplied in Cut Tape packaging, while the ES2HA M2G packaging format is not specified. Both parts are discontinued at DiGi Electronics. The ES2HA (without suffix) in Tape & Reel packaging is the recommended active alternative.

Q: Is the AES2HF-HF suitable as a substitute?

A: Yes. The AES2HF-HF is a parametric equivalent with matching voltage (500 V), current (2 A), forward voltage (1.7 V @ 2 A), and recovery time (35 ns) specifications. The AES2HF-HF features lower reverse leakage (5 µA versus 10 µA) and AEC-Q101 automotive qualification. This part is available in active product status and is suitable for direct substitution.

Q: Can the UFS150JE3/TR13 replace the ES2HA M2G?

A: The UFS150JE3/TR13 shares the 500 V voltage rating but is rated for 1 A average rectified current, compared to 2 A for the ES2HA M2G. This part is suitable only for applications where the current requirement does not exceed 1 A or where parallel device configurations are implemented. The UFS150JE3/TR13 uses a DO-214BA package rather than DO-214AC, requiring PCB layout verification for mechanical compatibility.

Q: What packaging formats are available for equivalent parts?

A: The ES2HA is available in Tape & Reel (TR) packaging. The ES2HA R3G is available in Cut Tape (CT) packaging. The AES2HF-HF is available in Tape & Reel (TR) packaging. The UFS150JE3/TR13 is available in Tape & Reel (TR) packaging. Packaging selection depends on assembly process requirements and volume considerations.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (ES2HA, ES2HA R3G, AES2HF-HF, and UFS150JE3/TR13) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original ES2HA M2G specification.

Q: What is the temperature operating range for each substitute?

A: The ES2HA, ES2HA R3G, and AES2HF-HF operate from -55°C to 150°C junction temperature. The UFS150JE3/TR13 operates from -55°C to 175°C, providing an extended upper temperature limit of 25°C. Selection of the UFS150JE3/TR13 is appropriate for applications requiring enhanced thermal performance, subject to current rating verification.
