Substitute Part Grouping Explanation

Substitution of the ES2CA M2G is determined by the following critical parameters:

Parametric Equivalents share identical electrical specifications: 150 V reverse voltage, 2 A average rectified current, 950 mV forward voltage at 2 A, 35 ns reverse recovery time, and standard diode technology. These parts are direct functional replacements with no performance trade-offs.

Similar Parts maintain the same package format (DO-214AC/SMA) and voltage rating (150 V) but differ in one or more of the following: current rating, forward voltage characteristics, reverse leakage current, capacitance, or diode technology (Schottky versus standard). Selection of similar parts requires circuit-level analysis to confirm compatibility with the application's current and thermal requirements.

The following parameters establish substitution boundaries:

Voltage - DC Reverse (Vr) Maximum: 150 V minimum
Current - Average Rectified (Io): 2 A minimum for direct equivalence
Package / Case: DO-214AC (SMA) surface mount
Technology: Standard diode technology for parametric equivalents
Operating Temperature Range: -55°C to 150°C minimum

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacements)

ES2CA and ES2CAH are parametric equivalents of the discontinued ES2CA M2G. Both parts maintain identical electrical specifications and package format. ES2CA is available in Tape & Reel (TR) packaging with active product status. ES2CAH is available with automotive-grade qualification (AEC-Q101) and active product status, suitable for applications requiring automotive-level reliability and traceability.

Selection between ES2CA and ES2CAH depends on application requirements. Standard industrial applications use ES2CA. Automotive and mission-critical applications requiring AEC-Q101 qualification use ES2CAH.

Similar Parts with Current Rating Equivalence

CDBA2150-HF (Comchip Technology) matches the 2 A current rating and 150 V voltage specification of the ES2CA M2G. This part uses Schottky diode technology, resulting in lower forward voltage (870 mV versus 950 mV at rated current) and higher reverse leakage current (500 µA versus 10 µA). The Schottky technology provides faster switching characteristics suitable for high-frequency applications. Operating temperature range is identical (-55°C to 150°C). This part is suitable for applications where lower forward voltage drop and faster recovery are beneficial.

Similar Parts with Current Rating Derating

CDBA1150-HF and CDBA1200-HF are rated for 1 A average rectified current, requiring current derating for 2 A applications. These parts are not suitable as direct replacements for 2 A circuits.

CDBA3150-HF and CDBA5150-HF are rated for 3 A and 5 A respectively, providing current margin above the 2 A requirement. Both parts use Schottky technology with lower forward voltage and higher reverse leakage. Operating temperature range extends to 175°C maximum. These parts are suitable for applications requiring higher current capacity or extended temperature operation.

Similar Parts with Current Rating Derating (1 A)

ES1C-13-F (Diodes Incorporated), ES1C-E3/5AT, and ES1C-E3/61T (Vishay General Semiconductor) are rated for 1 A average rectified current. These standard diode technology parts are not suitable as direct replacements for 2 A circuits without circuit redesign.

All substitute parts maintain RoHS3 compliance, MSL 1 (unlimited), and REACH unaffected status consistent with the original ES2CA M2G specification.

Frequently Asked Questions (FAQ)

Q: Can ES2CA be used as a direct replacement for ES2CA M2G?

A: Yes. ES2CA is a parametric equivalent with identical electrical specifications (150 V, 2 A, 950 mV forward voltage, 35 ns recovery time) and package format (DO-214AC/SMA). The primary difference is product status: ES2CA M2G is discontinued while ES2CA is active. ES2CA is available in Tape & Reel packaging.

Q: What is the difference between ES2CA and ES2CAH?

A: Both parts are parametric equivalents with identical electrical specifications. ES2CAH carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. ES2CA is standard industrial grade. Selection depends on application requirements and qualification mandates.

Q: Can CDBA2150-HF replace ES2CA M2G?

A: CDBA2150-HF matches the 2 A current rating and 150 V voltage specification. However, it uses Schottky diode technology instead of standard diode technology. This results in lower forward voltage (870 mV versus 950 mV) and higher reverse leakage current (500 µA versus 10 µA). Schottky diodes are suitable for applications where lower forward voltage drop and faster switching are beneficial. Circuit-level analysis is required to confirm compatibility.

Q: Why are ES1C-13-F, ES1C-E3/5AT, and ES1C-E3/61T listed as similar parts if they are only rated for 1 A?

A: These parts are listed as similar because they share the same 150 V voltage rating, standard diode technology, and DO-214AC/SMA package format. However, their 1 A current rating is insufficient for direct replacement in 2 A applications. These parts are included for reference in applications where current requirements can be reduced or where multiple devices can be paralleled.

Q: What is the significance of reverse recovery time (trr) in diode selection?

A: Reverse recovery time affects switching speed and electromagnetic interference characteristics. The ES2CA M2G has a 35 ns reverse recovery time. Schottky alternatives (CDBA series) have faster recovery (≤500 ns specification, typically faster in practice). Standard diode alternatives from Diodes Incorporated and Vishay have 25 ns recovery time. Faster recovery times reduce switching losses in high-frequency applications.

Q: Can higher-rated current diodes (CDBA3150-HF, CDBA5150-HF) be used in place of ES2CA M2G?

A: Yes, with circuit-level analysis. CDBA3150-HF (3 A) and CDBA5150-HF (5 A) provide current margin above the 2 A requirement. Both use Schottky technology with lower forward voltage and higher reverse leakage. Operating temperature extends to 175°C. These parts are suitable for applications requiring higher current capacity, lower forward voltage drop, or extended temperature operation.

Q: What packaging options are available for equivalent parts?

A: ES2CA is available in Tape & Reel (TR) packaging. ES2CAH packaging is not specified. Comchip CDBA series parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Diodes Incorporated ES1C-13-F is available in Tape & Reel (TR). Vishay parts ES1C-E3/5AT and ES1C-E3/61T are available in Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) respectively. Packaging selection depends on assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance, MSL 1 (unlimited moisture sensitivity level), and REACH unaffected status consistent with the original ES2CA M2G specification.
