Substitute Part Grouping Explanation

Substitution of the ES2G R5G is determined by strict alignment of electrical and mechanical parameters within the rectifier diode category. The primary substitution criteria are:

Critical Parameters (Must Match):

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount

Secondary Parameters (Allowable Variance):

Voltage - Forward (Vf) (Max) @ If: 1.3 V nominal; minor deviations acceptable within design margin
Reverse Recovery Time (trr): 35 ns nominal; faster recovery times are acceptable
Current - Reverse Leakage @ Vr: 10 µA nominal; lower leakage is acceptable
Operating Temperature - Junction: -55°C to 150°C minimum; extended ranges are acceptable

Substitute parts are classified into two categories:

Parametric Equivalents: Parts with identical or superior electrical specifications and matching package, available in active product status with full compliance certifications.

Similar Parts: Components with matching voltage and current ratings and package type but with variations in secondary parameters such as forward voltage, recovery time, or leakage current. These parts are suitable for applications where the specific secondary parameter variation does not impact circuit performance.

Engineering Selection Recommendations

Primary Substitutes (Parametric Equivalents):

The ES2GH, ES2LG, and ES2LGH from Taiwan Semiconductor Corporation are direct parametric equivalents to the ES2G R5G. These parts maintain identical electrical specifications across all critical parameters: 400 V reverse voltage, 2 A average rectified current, 1.3 V forward voltage at 2 A, and 35 ns reverse recovery time. All three are in active product status with ROHS3 compliance and MSL 1 rating. The ES2GH and ES2LGH carry AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability. The ES2G from YAGEO provides an alternative from a different manufacturer with matching core specifications and active status.

Secondary Substitutes (Parametric Equivalents with Minor Variations):

The HS2G from Good-Ark Semiconductor matches all critical parameters with a reverse recovery time of 50 ns (versus 35 ns) and reduced reverse leakage of 5 µA (versus 10 µA). The RS2G from Taiwan Semiconductor Corporation maintains critical parameters but features a longer reverse recovery time of 150 ns and reduced reverse leakage of 5 µA. Both parts are in active status with full compliance certifications.

Similar Parts (Matching Voltage and Current, Parameter Variations):

The CGRB204-G and CSFB204-G from Comchip Technology both support 400 V and 2 A specifications in DO-214AA packaging. The CGRB204-G exhibits standard recovery characteristics (>500 ns) with 1.1 V forward voltage, suitable for applications where recovery speed is not critical. The CSFB204-G provides fast recovery (35 ns) with 1.25 V forward voltage, offering closer alignment to the original part's performance profile.

The ER1G-LTP from Micro Commercial Co is rated for 1 A average rectified current, making it unsuitable as a direct substitute for 2 A applications but available for reference in lower-current designs.

Packaging Consideration:

The original ES2G R5G is supplied in Cut Tape (CT) packaging. All identified substitutes are available in Tape & Reel (TR) packaging, which is standard for production environments and offers superior handling and automated assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ES2GH replace the ES2G R5G directly in production?

A: Yes. The ES2GH is a parametric equivalent with identical electrical specifications (400 V, 2 A, 1.3 V forward voltage, 35 ns recovery time) and matching DO-214AA package. The primary difference is packaging format (Tape & Reel versus Cut Tape) and active product status. The ES2GH includes AEC-Q101 automotive qualification, which may provide additional assurance for certain applications.

Q: What is the difference between ES2LG and ES2LGH?

A: Both parts are parametric equivalents with identical electrical specifications. The ES2LGH carries AEC-Q101 automotive qualification and is designated for automotive-grade applications, while the ES2LG is the standard industrial version. Both are in active status with equivalent availability.

Q: Is the HS2G a suitable replacement?

A: The HS2G is a parametric equivalent with matching 400 V and 2 A ratings and identical forward voltage. The reverse recovery time is 50 ns (versus 35 ns in the original), and reverse leakage is reduced to 5 µA. For most general-purpose rectification applications, this variation is acceptable. Applications with strict timing requirements for fast recovery may require evaluation.

Q: Why is the RS2G listed as a substitute if it has 150 ns recovery time?

A: The RS2G maintains all critical electrical parameters (400 V, 2 A, 1.3 V forward voltage) and package specifications. The 150 ns reverse recovery time represents a slower recovery characteristic compared to the original 35 ns. This part is suitable for applications where recovery speed is not a limiting factor. Applications requiring fast recovery should prioritize ES2GH, ES2LG, or ES2LGH.

Q: Can CGRB204-G be used as a direct substitute?

A: The CGRB204-G matches voltage and current ratings (400 V, 2 A) and package type (DO-214AA). However, it exhibits standard recovery characteristics (>500 ns) versus the original's fast recovery (35 ns), and forward voltage is reduced to 1.1 V. This part is suitable for applications where recovery speed is not critical. For applications requiring fast recovery performance, CSFB204-G or the parametric equivalents (ES2GH, ES2LG, ES2LGH) are preferred.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component has unlimited shelf life under standard storage conditions without requiring special moisture-control packaging or baking procedures prior to assembly. Both the original part and all identified substitutes carry this rating.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the original ES2G R5G specification. This ensures compatibility with environmental and regulatory requirements across all identified alternatives.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual component strips cut to specific lengths, typically used for manual assembly or small-volume applications. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for automated pick-and-place assembly in production environments. All substitutes are available in Tape & Reel format, which is standard for modern manufacturing processes.

Q: Can ER1G-LTP be used in place of ES2G R5G?

A: No. The ER1G-LTP is rated for 1 A average rectified current, while the ES2G R5G is rated for 2 A. Using a 1 A component in a 2 A application would result in component overstress and potential failure. The ER1G-LTP is suitable only for applications with 1 A or lower current requirements.
