Engineering Selection Recommendations

Parametric Equivalent Parts (Direct Substitution):

The following parts maintain identical electrical characteristics and operating temperature ranges as the ES2CHR5G and are suitable for direct substitution:

ES2CH (Taiwan Semiconductor Corporation): Active product status with automotive-grade qualification and AEC-Q101 certification matching the original part. Identical forward voltage, reverse recovery time, and reverse leakage specifications. Recommended for applications requiring automotive compliance continuity.
ER2C_R1_00001 (Panjit International Inc.): Active product status with identical electrical specifications. Superior reverse leakage performance (1 µA vs. 10 µA) provides enhanced reliability margin. Suitable for all applications where the ES2CHR5G was specified.
ES2C R5G (Taiwan Semiconductor Corporation): Identical specifications to ES2CHR5G but currently discontinued at DiGi Electronics. Not recommended for new designs due to product status.
ES2C (Diotec Semiconductor): Active product with improved reverse recovery time (20 ns vs. 35 ns) and lower reverse leakage (5 µA vs. 10 µA). Minimum operating temperature is -50°C versus -55°C; verify compatibility with application requirements. Forward voltage is 50 mV lower (900 mV vs. 950 mV), which may affect circuit performance in voltage-sensitive applications.

Similar Parts (Application-Dependent Substitution):

The following parts meet all mandatory parameters but exhibit variations in acceptable parameters:

ES2C-13-F (Diodes Incorporated): Active product with forward voltage of 920 mV (30 mV lower than original) and reverse recovery time of 25 ns (10 ns faster). Lower reverse leakage (5 µA) improves performance. Suitable for applications where improved switching speed is beneficial.
ESH2C-E3/52T and ESH2C-E3/5BT (Vishay General Semiconductor - Diodes Division): Active products with extended operating temperature range (-55°C to 175°C vs. -55°C to 150°C). Forward voltage of 930 mV (20 mV lower) and significantly lower reverse leakage (2 µA). Recommended for high-temperature applications or where superior leakage performance is required. Packaging differs (Tape & Reel vs. unspecified for original part).

Product Status Considerations:

The ES2CHR5G is discontinued at DiGi Electronics. For new production and design continuity, ES2CH (active, automotive-qualified) or ER2C_R1_00001 (active, parametric equivalent) are the primary recommendations. Both maintain full electrical and thermal compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can ES2C be used as a direct replacement for ES2CHR5G?

A: ES2C is a parametric equivalent with identical voltage and current ratings and package type. However, it exhibits three parameter variations: forward voltage is 50 mV lower (900 mV vs. 950 mV), reverse recovery time is 15 ns faster (20 ns vs. 35 ns), and reverse leakage is 5 µA lower (5 µA vs. 10 µA). The minimum operating temperature is -50°C instead of -55°C. Verify that these variations are acceptable for your specific circuit design before substitution.

Q: What is the difference between "Parametric Equivalent" and "Similar" classifications?

A: Parametric Equivalent parts maintain all mandatory electrical parameters (voltage rating, current rating, package type, speed classification) and keep acceptable variation parameters within specified tolerances (±50 mV forward voltage, ±15 ns reverse recovery time, ±10 µA reverse leakage). Similar parts exceed one or more acceptable variation tolerances while maintaining all mandatory parameters. Parametric Equivalent parts are suitable for direct substitution; Similar parts require application-specific evaluation.

Q: Is ES2CH suitable for automotive applications?

A: Yes. ES2CH carries automotive-grade classification with AEC-Q101 qualification, identical to the ES2CHR5G. It is an active product and maintains all electrical specifications of the original part, making it suitable for automotive applications requiring the same qualification level.

Q: Why does ER2C_R1_00001 have lower reverse leakage (1 µA) than the original part (10 µA)?

A: Reverse leakage variation is a normal characteristic difference between manufacturers and production processes. Lower reverse leakage indicates superior performance and provides additional reliability margin. This variation is within acceptable parameters and does not preclude substitution.

Q: Can ESH2C-E3/52T be used in applications with a maximum operating temperature of 150°C?

A: Yes. ESH2C-E3/52T has a maximum operating temperature of 175°C, which exceeds the 150°C requirement. The part is fully compatible with applications limited to 150°C operation. The extended temperature range provides additional design margin for thermal stress conditions.

Q: What is the significance of the DO-214AA (SMB) package designation?

A: DO-214AA and SMB are equivalent designations for the same surface mount package. All substitute parts listed use this identical package, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes. No board redesign is required when substituting between parts with this package designation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain RoHS3 compliance, matching the environmental and regulatory status of the ES2CHR5G. All parts are suitable for applications with RoHS compliance requirements.

Q: Which substitute part offers the best overall performance improvement?

A: Performance improvement depends on application requirements. ES2C-13-F and ESH2C-E3/52T both offer faster reverse recovery time (25 ns and 35 ns respectively vs. 35 ns original) and lower reverse leakage. ESH2C-E3/52T additionally provides extended temperature range (-55°C to 175°C). For general-purpose applications, ES2CH is recommended due to active product status and maintained automotive qualification. For high-temperature or high-reliability applications, ESH2C-E3/52T is recommended.

Q: What packaging options are available for substitute parts?

A: Most substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) packaging for production quantities. ES2CH and ES2C do not specify packaging format in the provided data. Verify packaging availability with your supplier for specific production requirements and order quantities.
