Substitute Part Grouping Explanation

Substitution of the ES2DHR5G is determined by strict equivalence across the following critical parameters: reverse voltage rating (200 V minimum), average rectified current capacity (2 A minimum), package type (DO-214AA/SMB surface mount), fast recovery speed classification, and reverse recovery time (35 ns or faster). All substitute parts must maintain ROHS3 compliance and operate within compatible temperature ranges.

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical specifications and automotive qualification. These parts are direct functional replacements with no design modifications required.

Similar Parts share the same voltage and current ratings, package type, and fast recovery characteristics but may exhibit minor variations in forward voltage, reverse leakage current, or temperature operating range. These parts are suitable for applications where the primary electrical parameters are the controlling factors and minor specification differences do not impact circuit performance.

Engineering Selection Recommendations

Primary Recommendation: ES2DH

The ES2DH from Taiwan Semiconductor Corporation is the optimal substitute for the discontinued ES2DHR5G. This part maintains identical electrical specifications across all critical parameters: 200 V reverse voltage, 2 A average rectified current, 950 mV forward voltage at 2 A, and 35 ns reverse recovery time. The ES2DH carries automotive-grade qualification under AEC-Q101, matching the original part's certification status. The component is currently in active production with 3,896 units in stock. Packaging is DO-214AA (SMB) surface mount, identical to the original. This part requires no circuit modifications and provides direct functional equivalence.

Secondary Recommendation: ER2D-LTP

The ER2D-LTP from Micro Commercial Co provides full electrical equivalence with 200 V reverse voltage and 2 A average rectified current in DO-214AA (SMB) packaging. Reverse recovery time is 35 ns, matching the original specification. Forward voltage is 950 mV at 2 A. Reverse leakage current is 5 µA at 200 V, lower than the original 10 µA specification. The part is in active production with 198,400 units in stock, providing excellent supply availability. Operating temperature range extends to -65°C to 175°C, exceeding the original -55°C to 150°C range. This part is suitable for applications where automotive qualification is not a requirement.

Tertiary Recommendation: ES2D-13-F

The ES2D-13-F from Diodes Incorporated offers 200 V reverse voltage and 2 A average rectified current in DO-214AA (SMB) packaging. Forward voltage is 920 mV at 2 A, 30 mV lower than the original specification. Reverse recovery time is 25 ns, faster than the original 35 ns. Reverse leakage current is 5 µA at 200 V. This part is in active production with 130,906 units in stock. The improved reverse recovery time may provide performance benefits in high-frequency switching applications. No circuit modifications are required.

Current Rating Consideration: ER3DB-TP

The ER3DB-TP from Micro Commercial Co is rated for 3 A average rectified current, exceeding the 2 A requirement of the original part. All other electrical parameters match: 200 V reverse voltage, 950 mV forward voltage, 35 ns reverse recovery time, and DO-214AA (SMB) packaging. This part is suitable for applications requiring design margin or where higher current capacity provides system-level benefits. The part is in active production with 2,200 units in stock.

Package Variant: ES2DA-13-F

The ES2DA-13-F from Diodes Incorporated is electrically equivalent to ES2D-13-F but uses DO-214AC (SMA) packaging instead of DO-214AA (SMB). This part is suitable only for designs where SMA package footprints are acceptable. Direct substitution into DO-214AA (SMB) footprints is not possible without PCB modification.

Not Recommended: ER1D-LTP

The ER1D-LTP from Micro Commercial Co is rated for only 1 A average rectified current, below the 2 A requirement of the original part. This part is unsuitable for direct substitution in applications requiring 2 A current capacity.

Frequently Asked Questions (FAQ)

Q: Can ES2DH be used as a direct replacement for ES2DHR5G without circuit modifications?

A: Yes. The ES2DH maintains identical electrical specifications across all critical parameters: 200 V reverse voltage, 2 A average rectified current, 950 mV forward voltage at 2 A, 35 ns reverse recovery time, and DO-214AA (SMB) packaging. Both parts carry AEC-Q101 automotive qualification. No circuit modifications are required.

Q: What is the difference between parametric equivalents and similar parts in this list?

A: Parametric equivalents (ES2D, ES2DH) maintain identical electrical specifications to the original ES2DHR5G. Similar parts (CSFB203-G, ER2D-LTP, ES2D-13-F, ESH2D-E3/52T, ESH2D-E3/5BT) share the same voltage and current ratings and package type but may exhibit minor variations in forward voltage, reverse leakage current, or reverse recovery time. Similar parts are suitable when these minor variations do not impact circuit performance.

Q: Why is automotive qualification important for this part?

A: The original ES2DHR5G carries AEC-Q101 automotive-grade qualification, indicating compliance with automotive industry reliability and quality standards. For applications in automotive systems, replacement parts should maintain this qualification level. The ES2DH preserves this certification; other substitutes do not carry automotive qualification.

Q: Can ER3DB-TP be used in place of ES2DHR5G?

A: Yes, with the understanding that ER3DB-TP is rated for 3 A average rectified current, exceeding the 2 A requirement. All other electrical parameters match: 200 V reverse voltage, 950 mV forward voltage, 35 ns reverse recovery time, and DO-214AA (SMB) packaging. This part is suitable for applications where higher current capacity provides design margin or system-level benefits.

Q: What is the significance of reverse recovery time in this application?

A: Reverse recovery time (trr) determines how quickly the diode transitions from forward conduction to reverse blocking when the applied voltage reverses. The original ES2DHR5G specifies 35 ns. Substitute parts with equal or faster reverse recovery times (such as ES2D-13-F at 25 ns) are suitable. Faster recovery times reduce switching losses in high-frequency applications.

Q: Is the ES2D from Good-Ark Semiconductor a suitable replacement?

A: The ES2D maintains identical electrical specifications to the original ES2DHR5G: 200 V reverse voltage, 2 A average rectified current, 950 mV forward voltage at 2 A, and 35 ns reverse recovery time in DO-214AA (SMB) packaging. However, the ES2D does not carry automotive-grade qualification. It is suitable for non-automotive applications where AEC-Q101 certification is not required.

Q: Why is ES2DA-13-F listed if it uses a different package?

A: ES2DA-13-F is included for reference as an electrically equivalent part from the same manufacturer (Diodes Incorporated) as ES2D-13-F. However, it uses DO-214AC (SMA) packaging instead of DO-214AA (SMB). Direct substitution into existing DO-214AA (SMB) footprints is not possible without PCB redesign. This part is suitable only for new designs where SMA packaging is acceptable.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This classification indicates that the diode exhibits fast recovery characteristics with a reverse recovery time of 500 ns or less when the reverse recovery current exceeds 200 mA. All substitute parts in this list meet this fast recovery classification, making them suitable for switching applications requiring rapid diode turn-off.

Q: Can I use ER1D-LTP as a substitute?

A: No. The ER1D-LTP is rated for only 1 A average rectified current, below the 2 A requirement of the original ES2DHR5G. Using this part in a 2 A application would exceed its current rating and result in excessive heat generation and potential device failure.

Q: What is the difference between forward voltage specifications at different current levels?

A: Forward voltage (Vf) varies with the applied forward current (If). The original ES2DHR5G specifies 950 mV at 2 A. Some substitute parts specify 920 mV at 2 A, representing a 30 mV reduction. This difference affects power dissipation in the diode. Lower forward voltage results in lower power loss. The difference is typically negligible in most circuit applications but may be significant in high-current or thermally constrained designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this document are ROHS3 compliant, matching the original ES2DHR5G compliance status. All parts are also REACH unaffected and carry EAR99 export classification.
