ES2B Equivalent & Substitute Parts

Part Overview

The ES2B is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain discontinuation, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ES2B are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 2 A
• Reverse Recovery Time (trr): 35 ns
• Package / Case: DO-214AA, SMB
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitutes are grouped into two categories:

Category 1: Parametric Equivalents with Identical Electrical Specifications

• ES2B R5G (Taiwan Semiconductor Corporation): Identical electrical parameters; packaging variant (Cut Tape & Digi-Reel® vs. Tape & Reel); product status Discontinued at DiGi Electronics
• ER2B_R1_00001 (Panjit International Inc.): Identical electrical parameters; manufacturer variant; product status Active; reverse leakage current 1 µA @ 100 V (lower than main part specification of 10 µA)

All substitute parts maintain the same voltage rating, current rating, forward voltage drop, recovery time, package type, temperature range, and compliance certifications as the main ES2B part.

Engineering Selection Recommendations

ES2B (Primary Selection) The ES2B remains the primary component choice. It is Active product status with full availability (55,400 pcs in stock), RoHS3 compliant, and REACH unaffected. This part is suitable for new designs and production applications requiring long-term supply assurance.

ES2B R5G (Secondary Selection) The ES2B R5G is a parametric equivalent from the same manufacturer with identical electrical specifications. However, this part is Discontinued at DiGi Electronics and carries lower inventory (1,233 pcs). The packaging variant (Cut Tape & Digi-Reel® vs. Tape & Reel) may affect procurement and assembly processes. This part is suitable only when existing inventory must be utilized or when packaging format compatibility is confirmed.

ER2B_R1_00001 (Alternative Selection) The ER2B_R1_00001 is manufactured by Panjit International Inc. and maintains Active product status with 2,229 pcs in stock. All electrical parameters match the ES2B specification. The reverse leakage current is 1 µA @ 100 V, which is lower than the ES2B specification of 10 µA, indicating superior leakage performance. This part is suitable as a direct substitute when supply of the ES2B is constrained and cross-manufacturer qualification is permitted.

All three parts satisfy RoHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity requirements.

Frequently Asked Questions (FAQ)

Q: Can ES2B R5G be used as a direct replacement for ES2B? A: Yes. The ES2B R5G is a parametric equivalent with identical electrical specifications (100 V, 2 A, 950 mV forward voltage, 35 ns recovery time). The primary difference is packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel) and product status (Discontinued at DiGi Electronics). Confirm packaging compatibility with assembly equipment before substitution.

Q: What is the difference between ES2B and ER2B_R1_00001? A: Both parts are electrically equivalent with identical voltage, current, and recovery time specifications. The ER2B_R1_00001 is manufactured by Panjit International Inc. instead of Taiwan Semiconductor Corporation. The ER2B_R1_00001 exhibits lower reverse leakage current (1 µA vs. 10 µA @ 100 V), which may provide improved performance in low-leakage applications. Both are Active product status.

Q: Are all substitute parts RoHS3 compliant? A: Yes. The ES2B, ES2B R5G, and ER2B_R1_00001 are all RoHS3 compliant and REACH unaffected. All parts carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: Can ER2B_R1_00001 be used in applications where ES2B is specified? A: Yes. The ER2B_R1_00001 meets all electrical and mechanical requirements of the ES2B specification. The lower reverse leakage current (1 µA) is within acceptable limits for applications designed for the 10 µA specification. Cross-manufacturer substitution is permitted when design documentation does not restrict supplier selection.

Q: What is the difference in packaging between ES2B and ES2B R5G? A: The ES2B is supplied in Tape & Reel (TR) format. The ES2B R5G is supplied in Cut Tape (CT) & Digi-Reel® format. Both use the same DO-214AA (SMB) package case. Verify that assembly equipment supports the selected packaging format before procurement.

Q: Are there temperature or compliance differences between the substitute parts? A: No. All three parts operate across the same junction temperature range (-55°C to 150°C) and carry identical RoHS3 and REACH compliance certifications. Moisture sensitivity level is MSL 1 (Unlimited) for all parts.
