ES2E Equivalent & Substitute Parts Reference

Part Overview

The ES2E is a general-purpose rectifier diode manufactured by SMC Diode Solutions, rated for 300 V DC reverse voltage and 2 A average rectified current in a surface mount SMA (DO-214AC) package. This diode is classified as Active product status and is currently in stock with 2300 units available. The ES2E is designed for fast recovery applications with a reverse recovery time of 35 nanoseconds, making it suitable for switching power supplies, converters, and general rectification circuits operating at moderate voltage and current levels.

Substitute parts become necessary when the primary component reaches end-of-life status, inventory depletion, or when alternative sourcing is required to meet supply chain objectives. The HS2FA R3G, manufactured by Taiwan Semiconductor Corporation, represents a viable alternative for applications where the specified electrical parameters remain compatible with circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES2E is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 300 V minimum
• Package / Case: DO-214AC (SMA) surface mount package
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C minimum

Compatible Variation Parameters:

• Current - Average Rectified (Io): 1.5 A or higher (substitute may have lower rating if application current requirement permits)
• Voltage - Forward (Vf) (Max): Substitute values must be evaluated against circuit power dissipation limits
• Reverse Recovery Time (trr): Substitute values up to 500 ns are acceptable for fast recovery classification
• RoHS Status: ROHS3 Compliant required for regulatory alignment

The HS2FA R3G meets all mandatory matching parameters and operates within the compatible variation range, with the exception of a reduced average rectified current rating of 1.5 A compared to the ES2E's 2 A specification. This substitution is valid only for applications where the circuit current requirement does not exceed 1.5 A.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (ES2E): The ES2E remains the preferred selection for new designs and applications requiring the full 2 A average rectified current specification. The part is Active status with 2300 units in stock, ensuring supply continuity. ROHS3 compliance and RoHS Affected REACH status align with current regulatory requirements for commercial and industrial applications.

Substitute Part Selection (HS2FA R3G): The HS2FA R3G is suitable as a substitute only when the following conditions are met:

• Circuit design current requirement does not exceed 1.5 A
• Application can tolerate the increased reverse recovery time of 50 ns versus 35 ns
• Application can tolerate the increased junction capacitance of 50 pF versus 25 pF
• Packaging format change from Tape & Reel to Cut Tape is acceptable for procurement workflow

The HS2FA R3G is listed as Discontinued at DiGi Electronics, indicating limited future availability. This part should be considered only for legacy system support or when ES2E inventory is unavailable and current requirements permit the lower rating.

Compliance Considerations: Both parts maintain ROHS3 compliance. The ES2E carries REACH Affected status while the HS2FA R3G is REACH Unaffected. For applications subject to REACH regulations, the ES2E is the compliant choice. Both parts carry EAR99 ECCN classification and 8541.10.0080 HTSUS code.

Frequently Asked Questions (FAQ)

Q: Can the HS2FA R3G directly replace the ES2E in all applications?

A: No. The HS2FA R3G has a lower average rectified current rating of 1.5 A compared to the ES2E's 2 A specification. Direct substitution is valid only for circuits where the actual operating current does not exceed 1.5 A. Exceeding this current rating will result in excessive junction temperature and potential device failure.

Q: What is the impact of the different reverse recovery times (35 ns vs. 50 ns)?

A: The HS2FA R3G has a reverse recovery time of 50 ns compared to the ES2E's 35 ns. Both remain within the fast recovery classification (≤ 500 ns). The longer recovery time in the substitute may increase switching losses and EMI generation in high-frequency switching applications. Circuit simulation or testing is necessary to determine if this difference affects performance in the specific application.

Q: Are the DO-214AC and SMA packages identical?

A: Yes. DO-214AC and SMA refer to the same surface mount package. Both the ES2E and HS2FA R3G use this identical package, ensuring PCB footprint compatibility.

Q: Why does the HS2FA R3G have higher capacitance (50 pF vs. 25 pF)?

A: The increased junction capacitance in the HS2FA R3G is a characteristic of the device design. Higher capacitance may affect high-frequency circuit performance, particularly in switching applications or circuits with tight timing requirements. Evaluate circuit impact before substitution.

Q: What is the significance of the packaging format difference (Tape & Reel vs. Cut Tape)?

A: The ES2E is supplied in Tape & Reel format, suitable for automated assembly processes. The HS2FA R3G is supplied in Cut Tape format, which requires manual handling or different automated equipment. This difference affects procurement, storage, and assembly workflow but does not impact electrical performance or PCB compatibility.

Q: Is the HS2FA R3G still available for new orders?

A: The HS2FA R3G is listed as Discontinued at DiGi Electronics, indicating limited or no future availability through standard distribution channels. The ES2E, with Active status and 2300 units in stock, is the recommended choice for ongoing production and new designs.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. However, the ES2E is REACH Affected while the HS2FA R3G is REACH Unaffected. For applications subject to REACH regulations, verify that the ES2E's REACH Affected status is acceptable for your supply chain and end-use market.

Q: What is the forward voltage difference between these parts?

A: The ES2E has a maximum forward voltage of 1.25 V at 2 A, while the HS2FA R3G has a maximum forward voltage of 1 V at 1.5 A. The lower forward voltage in the substitute reduces power dissipation at its rated current. However, direct comparison at identical current levels is not possible due to the different current ratings. Evaluate power dissipation impact based on actual circuit operating current.
