Substitute Part Grouping Explanation
Substitution of the ES2GA R3G is determined by the following critical parameters:
Primary Substitution Criteria:
- Voltage - DC Reverse (Vr) (Max): Must equal or exceed 400 V
- Current - Average Rectified (Io): Must equal or exceed 2 A
- Package / Case: Must be DO-214AC (SMA) surface mount
- Mounting Type: Must be surface mount
- Operating Temperature Range: Must accommodate -55°C to 150°C minimum
Secondary Compatibility Factors:
- Voltage - Forward (Vf): Lower values indicate improved efficiency
- Reverse Recovery Time (trr): Lower values indicate faster switching capability
- Current - Reverse Leakage: Lower values indicate reduced standby current
- RoHS and MSL Compliance: Must maintain ROHS3 compliance and MSL 1 rating
Parts are classified as Parametric Equivalents when all primary criteria are met with identical electrical specifications. Parts are classified as Similar when current rating is reduced (1 A instead of 2 A) or recovery characteristics differ, requiring application-level verification of suitability.

Engineering Selection Recommendations
Parametric Equivalent - Direct Replacement:
ES2GAH (Taiwan Semiconductor Corporation) is the direct parametric equivalent to ES2GA R3G. This part maintains identical electrical specifications including 400 V reverse voltage, 2 A average rectified current, 1.3 V forward voltage at 2 A, 35 ns reverse recovery time, and 10 µA reverse leakage current. The ES2GAH is supplied in Tape & Reel (TR) packaging and carries AEC-Q101 automotive qualification. Product status is Active with 15,629 units in stock. This part is suitable for direct substitution in all applications where ES2GA R3G was specified.
Parametric Equivalent - Enhanced Performance:
ES2GA (SURGE) meets all primary substitution criteria with 400 V reverse voltage and 2 A average rectified current in DO-214AC (SMA) package. This part offers improved performance characteristics with 1.25 V forward voltage (reduced from 1.3 V), 25 ns reverse recovery time (reduced from 35 ns), and 5 µA reverse leakage current (reduced from 10 µA). Product status is Active with 305,000 units in stock. This part is suitable for direct substitution with performance benefits in switching efficiency and leakage current.
Similar Parts - Reduced Current Rating:
CFRA104-G, CGRA4004-G, CMR1-04M variants, CMR1F-04M variants, and CMR1U-04M variants are rated for 1 A average rectified current instead of 2 A. These parts maintain 400 V reverse voltage and DO-214AC (SMA) package compatibility. These parts are suitable only for applications where the circuit current requirement does not exceed 1 A. Application-level verification is required to confirm current margin adequacy.
All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating consistent with the original ES2GA R3G specification.
Frequently Asked Questions (FAQ)
Q: Can ES2GAH be used as a direct replacement for ES2GA R3G?
A: Yes. ES2GAH is a parametric equivalent with identical electrical specifications. Both parts are rated for 400 V reverse voltage, 2 A average rectified current, 1.3 V forward voltage at 2 A, and 35 ns reverse recovery time. The primary difference is packaging format (Tape & Reel versus bag) and automotive qualification (AEC-Q101) on the ES2GAH. Both parts are surface mount DO-214AC (SMA) package.
Q: What is the difference between ES2GA (SURGE) and ES2GA R3G?
A: Both parts meet the primary substitution criteria of 400 V reverse voltage and 2 A average rectified current in DO-214AC (SMA) package. ES2GA (SURGE) offers improved performance with lower forward voltage (1.25 V versus 1.3 V), faster reverse recovery time (25 ns versus 35 ns), and lower reverse leakage current (5 µA versus 10 µA). These improvements reduce power dissipation and switching losses.
Q: Can 1 A rated parts (CFRA104-G, CMR1-04M, CMR1F-04M, CMR1U-04M) replace the 2 A ES2GA R3G?
A: These parts are suitable only for applications where the circuit current requirement does not exceed 1 A. The ES2GA R3G is rated for 2 A average rectified current. Using a 1 A rated part in a 2 A application will result in device overstress and potential failure. Verify circuit current requirements before selecting a 1 A alternative.
Q: What is the significance of reverse recovery time (trr) differences?
A: Reverse recovery time affects switching speed and switching losses in high-frequency applications. ES2GA R3G has 35 ns trr. ES2GA (SURGE) has 25 ns (faster), while CFRA104-G and CMR1F-04M variants have 150 ns (slower). Faster recovery times reduce switching losses but may increase EMI. Application frequency and circuit topology determine whether trr differences are significant.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance consistent with ES2GA R3G specification. All parts also maintain MSL 1 (Unlimited) moisture sensitivity rating.
Q: What is the difference between Bulk and Tape & Reel (TR) packaging?
A: Bulk packaging is suitable for manual assembly and small-volume applications. Tape & Reel (TR) packaging is suitable for automated pick-and-place assembly and high-volume production. Both packaging formats contain identical components; the difference is in delivery and handling format. Select packaging based on assembly process requirements.
Q: Why do some parts show "REACH Status: Vendor Undefined"?
A: REACH Status indicates compliance with European chemical regulations. "Vendor Undefined" indicates the manufacturer has not provided explicit REACH compliance documentation. "REACH Unaffected" indicates the part does not contain substances of concern under REACH regulations. For applications requiring explicit REACH compliance documentation, select parts with "REACH Unaffected" status.
Q: Can CMR1U-04M variants be used in high-temperature applications?
A: CMR1U-04M variants are rated for -65°C to 175°C operating temperature range, compared to ES2GA R3G at -55°C to 150°C. However, CMR1U-04M is rated for only 1 A current. If both high-temperature operation and 2 A current are required, CMR1U-04M is not suitable. Verify both current and temperature requirements before selection.
