Substitute Part Grouping Explanation

Substitute parts for the ES2DA R3G are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical or superior performance across all critical electrical parameters: 200 V reverse voltage rating, 2 A average rectified current, fast recovery speed classification, DO-214AC package, and surface mount configuration. These parts are direct functional replacements with no circuit redesign required.

Similar Parts share the same package, voltage rating, and speed classification but differ in current rating or diode technology. These parts are suitable for applications where the specified current rating can be exceeded without adverse effects, or where alternative diode technologies (such as Schottky) provide performance benefits.

The critical parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) rating: must equal or exceed 200 V
Current - Average Rectified (Io): must equal or exceed 2 A for parametric equivalents
Package / Case: must be DO-214AC (SMA) surface mount
Speed classification: must maintain fast recovery characteristics
Operating temperature range: must encompass -55°C to 150°C minimum

Engineering Selection Recommendations

Primary Equivalent (Parametric Match):

The ES2DA from Good-Ark Semiconductor is the recommended primary substitute. This part maintains identical voltage and current ratings (200 V, 2 A) with superior electrical performance: forward voltage drop reduced to 920 mV (versus 950 mV), reverse recovery time improved to 25 ns (versus 35 ns), and reverse leakage current reduced to 5 µA (versus 10 µA). The part is in active production status with substantial inventory availability (125,300 pcs). All compliance certifications match the original specification: ROHS3 compliant, MSL 1, REACH unaffected, and identical HTSUS classification.

Secondary Equivalent (Same Manufacturer, Active Status):

The ES2DAH from Taiwan Semiconductor Corporation provides an alternative from the original manufacturer. This part is electrically identical to the ES2DA R3G (950 mV forward voltage, 35 ns recovery time, 10 µA leakage) but differs in packaging format (Tape & Reel versus Cut Tape) and includes automotive-grade qualification (AEC-Q101). This option is suitable for applications requiring original manufacturer continuity or automotive compliance. Product status is active with 15,960 pcs in inventory.

Alternative Technology (Schottky Diodes):

The CDBA2200-HF from Comchip Technology is a Schottky diode equivalent with identical 200 V / 2 A ratings. Schottky technology provides lower forward voltage (900 mV) and faster switching characteristics, beneficial for high-frequency applications. However, reverse leakage current is significantly higher (500 µA versus 10 µA), which may impact applications sensitive to standby power consumption. This part is active with 10,300 pcs available.

Higher Current Alternatives (Schottky):

The CDBA3200-HF (3 A) and CDBA5200-HF (5 A) from Comchip Technology provide increased current capacity in Schottky technology. These parts are suitable only for applications where the 2 A specification can be exceeded without adverse effects. Both parts are active with substantial inventory (36,554 and 33,051 pcs respectively).

Lower Current Parts (Not Recommended for Direct Substitution):

Parts rated for 1 A (CFRA103-G, CGRA4003-G, CMR1-02M variants, CMR1F-02M) are unsuitable as direct replacements for the 2 A ES2DA R3G specification. These parts are listed for reference only and should not be selected unless circuit requirements have been verified to operate at reduced current levels.

Frequently Asked Questions (FAQ)

Q: Can the ES2DA from Good-Ark Semiconductor be used as a direct replacement for the ES2DA R3G?

A: Yes. The Good-Ark ES2DA is a parametric equivalent with identical voltage (200 V) and current (2 A) ratings, matching package (DO-214AC), and superior electrical performance. No circuit modifications are required. The part is in active production with high inventory availability.

Q: What is the difference between the ES2DA R3G and ES2DAH?

A: Both parts are electrically identical (200 V, 2 A, 950 mV forward voltage, 35 ns recovery time). The primary differences are: ES2DA R3G is discontinued and supplied in Cut Tape packaging; ES2DAH is active production and supplied in Tape & Reel format, with automotive-grade qualification (AEC-Q101). Select ES2DAH for active procurement or automotive applications.

Q: Can Schottky diodes (CDBA series) replace the ES2DA R3G?

A: Schottky diodes are functionally compatible at the same voltage and current ratings but introduce different electrical characteristics. The CDBA2200-HF provides lower forward voltage (900 mV) and faster switching, beneficial for high-frequency circuits. However, reverse leakage current increases from 10 µA to 500 µA, which may impact low-power standby applications. Verify circuit requirements before substitution.

Q: Why are 1 A diodes (CFRA103-G, CMR1-02M) listed if they cannot replace the 2 A ES2DA R3G?

A: These parts are included for reference and cross-reference purposes only. They share the same 200 V voltage rating and DO-214AC package but are rated for half the current. They are not suitable as direct replacements unless circuit analysis confirms operation at reduced current levels.

Q: What packaging options are available for ES2DA equivalents?

A: The Good-Ark ES2DA is supplied in Cut Tape (CT) & Digi-Reel format. The Taiwan Semiconductor ES2DAH is supplied in Tape & Reel (TR) format. Both are surface mount DO-214AC packages. Verify packaging compatibility with assembly equipment before procurement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance, MSL 1 (unlimited moisture sensitivity), and REACH unaffected status, matching the original ES2DA R3G specification.

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

A: Reverse recovery time determines switching speed and is critical in high-frequency applications. The ES2DA R3G specifies 35 ns. The Good-Ark ES2DA improves this to 25 ns, enabling faster switching. Parts with longer recovery times (150 ns for CFRA103-G, CMR1F-02M) are unsuitable for applications requiring fast switching performance.

Q: Can I use a higher-current Schottky diode (CDBA3200-HF or CDBA5200-HF) in place of the 2 A ES2DA R3G?

A: Yes, from an electrical compatibility standpoint. Higher current ratings provide design margin and are backward-compatible with 2 A circuit requirements. However, verify that increased capacitance (250 pF and 380 pF respectively, versus 25 pF for ES2DA R3G) does not adversely affect circuit performance in high-frequency applications.
