Substitute Part Grouping Explanation
Substitute parts for the ES2A-TP are categorized based on electrical parameter compatibility and package equivalence. The primary substitution criteria are:
Critical Parameters for Substitution:
- Voltage - DC Reverse (Vr) (Max): Must equal or exceed 50 V
- Current - Average Rectified (Io): Must equal or exceed 2 A
- Mounting Type: Surface Mount
- Package / Case: DO-214AC (SMA) compatible
- Speed Classification: Fast Recovery technology
- RoHS Status: ROHS3 Compliant
- Moisture Sensitivity Level: MSL 1
Substitution Categories:
Category 1: Direct Equivalents (50 V, 2 A Rating) Parts with identical voltage and current ratings maintain full functional equivalence. The ES2A-LTP from Micro Commercial Co represents a direct equivalent with improved reverse recovery time (35 ns vs. 50 ns) and lower forward voltage (950 mV vs. 975 mV at 2 A).
Category 2: Reduced Current Rating (50 V, 1 A Rating) Parts rated for 1 A average rectified current (ES1A series from Diodes Incorporated and Vishay) are suitable for applications where the 2 A capability of the ES2A-TP is not fully utilized. These parts maintain the 50 V reverse voltage rating and DO-214AC package compatibility. Forward voltage characteristics are superior (920 mV at 1 A) and reverse recovery time is faster (25 ns).
Category 3: Elevated Voltage Rating (100 V, 2 A Rating) The ES2BA-13-F from Diodes Incorporated provides increased voltage headroom (100 V vs. 50 V) while maintaining 2 A current capacity. This part is suitable for applications requiring higher voltage margin and is available in active product status.

Engineering Selection Recommendations
For Direct Replacement (Same Electrical Rating):
The ES2A-LTP from Micro Commercial Co provides the closest functional equivalent to the ES2A-TP. Both parts maintain 50 V reverse voltage and 2 A average rectified current ratings. The ES2A-LTP demonstrates improved electrical characteristics with lower forward voltage drop (950 mV vs. 975 mV at 2 A) and faster reverse recovery time (35 ns vs. 50 ns). However, the ES2A-LTP is classified as "Not For New Designs," limiting its suitability for new product development. The ES2A-LTP is suitable for legacy system maintenance and repair applications where the ES2A-TP is no longer available.
For New Designs with Reduced Current Requirements:
The ES1A series from Diodes Incorporated and Vishay General Semiconductor - Diodes Division are recommended for applications where 1 A average rectified current is sufficient. These parts are classified as Active and provide superior electrical performance characteristics: forward voltage of 920 mV at 1 A (compared to 975 mV at 2 A for the ES2A-TP) and reverse recovery time of 25 ns (compared to 50 ns). All ES1A variants maintain the 50 V reverse voltage rating and DO-214AC package compatibility.
Vishay ES1A Variants:
- ES1A-E3/5AT and ES1A-E3/61T: Standard industrial grade, Active status
- ES1A-M3/5AT and ES1A-M3/61T: Standard industrial grade, Active status
- ES1AHE3_A/H and ES1AHE3_A/I: Automotive grade with AEC-Q101 qualification, Active status
The automotive-qualified variants (ES1AHE3_A/H and ES1AHE3_A/I) are appropriate for applications requiring automotive-grade reliability and traceability.
For New Designs with Elevated Voltage Margin:
The ES2BA-13-F from Diodes Incorporated is recommended for applications requiring higher reverse voltage capability. This part maintains 2 A average rectified current while providing 100 V reverse voltage rating (double the ES2A-TP specification). The ES2BA-13-F is classified as Active and demonstrates superior electrical characteristics: forward voltage of 920 mV at 2 A and reverse recovery time of 25 ns. This part is suitable for new product designs where voltage margin enhancement is beneficial.
Compliance and Regulatory Considerations:
All recommended substitute parts are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the ES2A-TP specifications. All parts are classified as REACH Unaffected and carry EAR99 ECCN designation.
Frequently Asked Questions (FAQ)
Q: Can the ES1A series parts directly replace the ES2A-TP in all applications?
A: The ES1A series parts are suitable for applications where the average rectified current requirement does not exceed 1 A. If the application circuit requires 2 A capability, the ES1A series parts are not appropriate. The 50 V reverse voltage rating and DO-214AC package are compatible. Forward voltage and reverse recovery time characteristics of the ES1A series are superior to the ES2A-TP.
Q: What is the difference between ES1A-E3/61T and ES1A-M3/61T?
A: Both parts share identical electrical specifications: 50 V reverse voltage, 1 A average rectified current, 920 mV forward voltage at 1 A, and 25 ns reverse recovery time. The primary difference is packaging designation. Both are classified as Active and suitable for new designs.
Q: Are the automotive-qualified ES1AHE3_A/H and ES1AHE3_A/I variants interchangeable with standard ES1A parts?
A: The automotive-qualified variants (ES1AHE3_A/H and ES1AHE3_A/I) share identical electrical specifications with standard ES1A parts and are physically compatible in the same DO-214AC package. The automotive variants carry AEC-Q101 qualification and are appropriate for applications requiring automotive-grade traceability and reliability documentation. Standard ES1A parts are suitable for industrial and consumer applications.
Q: Why is the ES2A-LTP classified as "Not For New Designs" despite being a direct equivalent?
A: The ES2A-LTP classification reflects manufacturer product lifecycle decisions. While the ES2A-LTP provides equivalent or superior electrical performance to the ES2A-TP, the "Not For New Designs" status indicates the manufacturer is transitioning away from this product line. For new product development, the ES2BA-13-F (100 V, 2 A) or ES1A series (50 V, 1 A) are recommended as they carry Active status.
Q: Can the ES2BA-13-F (100 V, 2 A) be used in place of the ES2A-TP (50 V, 2 A)?
A: Yes, the ES2BA-13-F is a suitable substitute for the ES2A-TP in applications where the 2 A current rating is required. The ES2BA-13-F provides higher reverse voltage capability (100 V vs. 50 V), which is beneficial for applications with voltage margin requirements. The ES2BA-13-F is classified as Active and demonstrates superior electrical characteristics: forward voltage of 920 mV at 2 A and reverse recovery time of 25 ns. The DO-214AC package is compatible.
Q: What packaging options are available for substitute parts?
A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR), Cut Tape (CT), and Cut Tape & Digi-Reel® combinations. All substitute parts maintain the DO-214AC (SMA) surface mount package format compatible with the ES2A-TP. Packaging selection depends on procurement volume and assembly process requirements.
Q: Are all substitute parts RoHS3 Compliant?
A: Yes, all recommended substitute parts are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the ES2A-TP specifications. All parts are REACH Unaffected and carry EAR99 ECCN designation.
Q: What is the temperature operating range difference between the ES2A-TP and substitute parts?
A: The ES2A-TP operates from -50°C to 150°C. Most substitute parts operate from -55°C to 150°C or -55°C to 155°C, providing equivalent or slightly extended temperature range capability. The ES2A-LTP extends to -65°C to 175°C. Temperature range differences are not limiting factors for substitution in standard industrial applications.
