ES2C Equivalent & Substitute Parts

Part Overview

The ES2C is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 150 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 with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The ES2C serves applications requiring fast recovery rectification with a reverse recovery time of 35 nanoseconds, making it suitable for switching power supplies, converter circuits, and general rectification tasks. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and compliance certifications to ensure direct functional interchangeability in circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the ES2C are identified through parametric equivalence based on the following critical electrical and mechanical criteria:

Matching Parameters (Required for Substitution):

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 2 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 150 V (or lower)
• Capacitance @ Vr, F: 25 pF @ 4V, 1MHz
• Package / Case: DO-214AA, SMB (surface mount)
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts identified include ES2C R5G (Taiwan Semiconductor Corporation) and ER2C_R1_00001 (Panjit International Inc.). Both maintain identical electrical performance specifications and package compatibility, differing only in packaging format (Cut Tape versus Tape & Reel) and product status classification.

Engineering Selection Recommendations

Primary Selection: ES2C

The ES2C remains the preferred component choice for new designs and ongoing production. It maintains Active product status with full manufacturer support, ROHS3 compliance, and unlimited moisture sensitivity level. Current inventory of 43,700 pieces ensures supply continuity for production requirements.

Secondary Selection: ER2C_R1_00001

The ER2C_R1_00001 manufactured by Panjit International Inc. serves as the primary substitute when ES2C availability is constrained. This part maintains identical electrical specifications and package compatibility while offering superior reverse leakage characteristics (1 µA versus 10 µA at 150 V), resulting in lower power dissipation in reverse bias conditions. Active product status and ROHS3 compliance ensure regulatory alignment. Inventory of 2,900 pieces supports medium-term supply requirements. The Tape & Reel packaging format suits high-volume automated assembly operations.

Tertiary Selection: ES2C R5G

The ES2C R5G is a variant of the primary part from Taiwan Semiconductor Corporation with identical electrical performance. However, this part is classified as Discontinued at DiGi Electronics, indicating limited future availability. Use of this part is restricted to applications where existing inventory must be consumed or where supply chain continuity from alternative distributors is confirmed. Cut Tape packaging format is suitable for lower-volume or manual assembly processes.

Compliance Verification

All three parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 export classification. Moisture sensitivity level MSL 1 (Unlimited) eliminates special storage and handling requirements. All parts are suitable for operating environments spanning -55°C to 150°C junction temperature range.

Frequently Asked Questions (FAQ)

Q: Can ES2C R5G be used as a direct replacement for ES2C?

A: Yes. ES2C R5G is parametrically equivalent to ES2C with identical electrical specifications, reverse recovery time, and package configuration. The primary distinction is packaging format (Cut Tape versus standard packaging) and product status (Discontinued at DiGi Electronics). Electrical performance in circuit operation is identical.

Q: What is the difference between ES2C and ER2C_R1_00001?

A: Both parts are electrically equivalent with matching voltage ratings, current capacity, and reverse recovery time. The ER2C_R1_00001 exhibits lower reverse leakage current (1 µA versus 10 µA at 150 V), resulting in reduced power dissipation during reverse bias operation. ER2C_R1_00001 is manufactured by Panjit International Inc. and supplied in Tape & Reel format, while ES2C is manufactured by Taiwan Semiconductor Corporation. Both maintain Active product status and ROHS3 compliance.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use identical DO-214AA (SMB) surface mount package configuration. PCB footprints, solder pad dimensions, and mounting procedures are identical across ES2C, ES2C R5G, and ER2C_R1_00001. No circuit board redesign or assembly process modification is required.

Q: Which substitute part should be selected for new production designs?

A: ER2C_R1_00001 is recommended for new production designs when ES2C availability is limited. It maintains Active product status, offers superior reverse leakage characteristics, and is supplied in Tape & Reel format optimized for automated assembly. ES2C remains the primary choice when available due to established supply relationships and higher current inventory levels.

Q: Do these parts require special handling or storage conditions?

A: No. All three parts are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control or baking procedures are required. Standard component storage at room temperature and normal humidity conditions is acceptable.

Q: Are all substitute parts compliant with current regulatory requirements?

A: Yes. ES2C, ES2C R5G, and ER2C_R1_00001 all maintain ROHS3 compliance and REACH Unaffected status. All parts are classified under ECCN EAR99 for export purposes. Regulatory compliance is maintained across all three options.

Q: What is the significance of reverse recovery time (trr) in these specifications?

A: Reverse recovery time of 35 nanoseconds indicates fast recovery diode performance, suitable for high-frequency switching applications including switching power supplies and converter circuits. All three substitute parts maintain identical 35 ns reverse recovery time, ensuring equivalent performance in switching applications.

Q: Can ER2C_R1_00001 be used in applications where lower reverse leakage is critical?

A: Yes. ER2C_R1_00001 exhibits 1 µA reverse leakage current compared to 10 µA for ES2C and ES2C R5G. In applications where reverse bias power dissipation or leakage current is a design constraint, ER2C_R1_00001 provides superior performance while maintaining all other electrical specifications.
