Substitute Part Grouping Explanation
Substitution of the HS2AA M2G is determined by the following critical electrical and mechanical parameters:
Primary Substitution Criteria:
- Voltage - DC Reverse (Vr) (Max): 50 V minimum
- Current - Average Rectified (Io): 1.5 A minimum
- Package / Case: DO-214AC (SMA) surface mount
- Mounting Type: Surface Mount
- Operating Temperature Range: -55°C to 150°C minimum
Secondary Compatibility Factors:
- Speed classification (Fast Recovery ≤ 500ns preferred for performance matching)
- Reverse Recovery Time (trr): 50 ns or lower preferred
- Forward Voltage (Vf): 1 V or lower at rated current
- RoHS3 compliance and MSL 1 rating
Parts are grouped into two categories:
Parametric Equivalents: Parts with identical or superior electrical ratings (50 V, 1.5 A) in the same package, differing only in packaging format (Tape & Reel vs. Cut Tape) or revision level.
Similar Parts: Parts with reduced current ratings (1 A) or different speed characteristics but maintaining 50 V reverse voltage and DO-214AC package compatibility. These require design verification for current capacity adequacy.

Engineering Selection Recommendations
Direct Parametric Equivalents (Recommended Primary Substitutes):
The HS2AA (Tape & Reel format) is the direct parametric equivalent to HS2AA M2G, maintaining identical electrical specifications (50 V, 1.5 A, 50 ns trr) with active product status. This part is the preferred substitute for direct replacement in production environments.
The HS2AA R3G provides identical electrical performance in Cut Tape format, suitable for lower-volume or manual assembly applications. Both Taiwan Semiconductor Corporation parts maintain the same fast recovery characteristics and forward voltage profile.
Active Substitute Options (1 A Current Rating):
Parts from Vishay General Semiconductor (ES1A series variants) and Diodes Incorporated (ES1A-13-F) provide active product status with 50 V reverse voltage and fast recovery characteristics. These parts operate at 1 A average rectified current, representing a 33% reduction from the HS2AA M2G 1.5 A rating. Selection of these parts requires verification that circuit design accommodates the lower current capacity.
The ES1AHE3_A/H and ES1AHE3_A/I variants include AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components.
Current-Upgraded Alternative:
The ES2AA-13-F from Diodes Incorporated provides 2 A average rectified current, exceeding the HS2AA M2G specification. This part maintains 50 V reverse voltage, fast recovery speed, and active product status, offering design margin for current capacity.
Non-Recommended Substitute:
The CGRA4001-G from Comchip Technology operates at standard recovery speed (>500ns), which differs from the fast recovery characteristic (≤500ns) of the HS2AA M2G. This part is suitable only for applications where recovery speed is not a critical design parameter.
All recommended substitutes maintain RoHS3 compliance, MSL 1 rating, and DO-214AC (SMA) package compatibility.
Frequently Asked Questions (FAQ)
Q: Can the HS2AA (Tape & Reel) directly replace the HS2AA M2G?
A: Yes. The HS2AA in Tape & Reel format is a parametric equivalent with identical electrical specifications (50 V, 1.5 A, 50 ns reverse recovery time). The difference is packaging format only. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain the same performance characteristics.
Q: What is the difference between the HS2AA and HS2AA R3G?
A: Both parts are parametric equivalents with identical electrical ratings. The HS2AA is supplied in Tape & Reel format, while the HS2AA R3G is supplied in Cut Tape format. Selection depends on assembly process requirements and volume.
Q: Can I use a 1 A rated diode (ES1A series) instead of the 1.5 A HS2AA M2G?
A: The ES1A series parts (ES1A-13-F, ES1A-E3/5AT, ES1A-M3/5AT, ES1A-M3/61T, and automotive variants) operate at 1 A average rectified current. Substitution requires circuit design verification to confirm that the application does not exceed 1 A continuous current. These parts maintain 50 V reverse voltage and fast recovery characteristics, making them electrically compatible at reduced current capacity.
Q: What is the advantage of the ES2AA-13-F over the HS2AA M2G?
A: The ES2AA-13-F provides 2 A average rectified current, exceeding the HS2AA M2G specification by 33%. This part maintains 50 V reverse voltage, fast recovery speed (≤500ns), and active product status. Selection of this part provides additional design margin for current capacity without changing package or performance characteristics.
Q: Why is the CGRA4001-G not recommended as a substitute?
A: The CGRA4001-G operates at standard recovery speed (>500ns), whereas the HS2AA M2G is specified for fast recovery (≤500ns). This difference affects switching performance and electromagnetic interference characteristics. The CGRA4001-G is suitable only for applications where recovery speed is not a critical design parameter.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All parts listed in this reference maintain RoHS3 compliance and MSL 1 (unlimited) moisture sensitivity level, matching the environmental and regulatory requirements of the HS2AA M2G.
Q: What packaging formats are available for substitute parts?
A: Substitute parts are available in Tape & Reel (TR) and Cut Tape (CT) formats. The HS2AA is supplied in Tape & Reel format. The HS2AA R3G is supplied in Cut Tape format. Vishay ES1AHE3_A/H is supplied in Cut Tape & Digi-Reel® format. Selection depends on assembly equipment compatibility and procurement volume requirements.
Q: Do the Vishay automotive-qualified variants (ES1AHE3_A/H and ES1AHE3_A/I) have different electrical performance?
A: No. The automotive variants maintain identical electrical specifications to the standard ES1A series parts (50 V, 1 A, 920 mV forward voltage, 25 ns reverse recovery time). The difference is AEC-Q101 automotive qualification, which adds process and reliability requirements suitable for automotive applications.
Q: What is the operating temperature range for substitute parts?
A: All substitute parts operate across a junction temperature range of -55°C to 150°C, matching or exceeding the HS2AA M2G specification. The ES1A-E3/5AT extends to -55°C to 155°C, providing an additional 5°C upper temperature margin.
