Substitute Part Grouping Explanation

Substitution of the ES2CHM4G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Technology: Standard

Acceptable Variation Parameters:

Voltage - Forward (Vf) (Max) @ If: Within ±50 mV of 950 mV @ 2 A
Reverse Recovery Time (trr): Within ±15 ns of 35 ns
Current - Reverse Leakage @ Vr: Within ±10 µA @ 150 V
Operating Temperature - Junction: Minimum -55°C, maximum ≥150°C

Parts are classified as Parametric Equivalent when all mandatory parameters match exactly and acceptable variation parameters remain within specified tolerances. Parts are classified as Similar when one or more acceptable variation parameters fall outside specified tolerances while maintaining all mandatory parameters.

Engineering Selection Recommendations

Parametric Equivalent Parts (Direct Substitution):

The following parts maintain identical electrical characteristics within specified tolerances and are suitable for direct substitution:

ES2CH (Taiwan Semiconductor Corporation): Active product status with identical specifications to ES2CHM4G. Maintains automotive-grade classification and AEC-Q101 qualification. Recommended for applications requiring automotive compliance.
ES2C (Diotec Semiconductor): Active product with improved reverse leakage performance (5 µA vs. 10 µA) and faster recovery time (20 ns vs. 35 ns). Forward voltage is 50 mV lower (900 mV vs. 950 mV), resulting in reduced power dissipation. Operating temperature minimum is -50°C (vs. -55°C).
ER2C_R1_00001 (Panjit International Inc.): Active product with superior reverse leakage performance (1 µA vs. 10 µA). Maintains identical forward voltage and recovery time specifications. Suitable for applications with stringent leakage requirements.

Similar Parts (Conditional 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 main part) and faster recovery time of 25 ns (10 ns faster). Improved reverse leakage (5 µA vs. 10 µA). Supplied in Tape & Reel packaging.
ESH2C-E3/52T and ESH2C-E3/5BT (Vishay General Semiconductor - Diodes Division): Active products with forward voltage of 930 mV (20 mV lower) and superior reverse leakage (2 µA vs. 10 µA). Extended operating temperature range to 175°C. Supplied in Tape & Reel packaging.

Product Status Consideration:

ES2C R5G, while parametrically equivalent, shares discontinued status with the main part and is not recommended for new designs requiring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can ES2C from Diotec Semiconductor be used as a direct replacement for ES2CHM4G?

A: Yes. ES2C meets all mandatory electrical parameters (150 V, 2 A, DO-214AA package) and operates within acceptable variation limits. The lower forward voltage (900 mV vs. 950 mV) and faster recovery time (20 ns vs. 35 ns) represent performance improvements. However, the minimum operating temperature is -50°C instead of -55°C; verify this meets application requirements.

Q: What is the difference between parametric equivalent and similar classifications?

A: Parametric equivalent parts maintain all mandatory parameters and remain within specified acceptable variations for forward voltage, recovery time, and leakage current. Similar parts meet all mandatory parameters but exceed acceptable variation limits in one or more electrical characteristics. Both are functionally compatible; similar parts require engineering review of the specific parameter variations.

Q: Is ES2CH suitable for automotive applications?

A: Yes. ES2CH maintains automotive-grade classification and AEC-Q101 qualification identical to ES2CHM4G. It is an active product and recommended for automotive applications requiring these certifications.

Q: Why do some substitute parts have lower reverse leakage current?

A: Reverse leakage current variation is a normal characteristic difference between manufacturers and process technologies. Lower leakage (such as 1-5 µA vs. 10 µA) represents improved performance and does not prevent substitution. Applications sensitive to leakage current benefit from these alternatives.

Q: Does packaging format affect substitution compatibility?

A: All listed parts use DO-214AA (SMB) surface mount packaging and are mechanically compatible. Packaging format variations (Cut Tape, Tape & Reel) affect supply and handling but not electrical compatibility or PCB mounting.

Q: Can ESH2C-E3/52T be used in applications with operating temperatures above 150°C?

A: ESH2C-E3/52T supports junction temperatures to 175°C, compared to 150°C for ES2CHM4G. This extended range is available for applications requiring higher temperature operation. Verify that other circuit components support the extended temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant, matching the compliance status of ES2CHM4G.
