ES2CH Equivalent & Substitute Parts

Part Overview

The ES2CH 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 and carries automotive-grade qualification under AEC-Q101 standard.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or alternative sourcing from qualified manufacturers is required to maintain supply chain continuity. The ES2C R5G variant has been discontinued at DiGi Electronics, making equivalent alternatives essential for ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the ES2CH is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) Maximum: 150 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) Maximum @ If: 950 mV @ 2 A
Reverse Recovery Time (trr): 35 ns
Package / Case: DO-214AA, SMB
Operating Temperature - Junction: -55°C to 150°C
Technology: Standard
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Variation Parameters:

Current - Reverse Leakage @ Vr: Equivalent or lower values are acceptable
Capacitance @ Vr, F: Equivalent values at specified conditions
Mounting Type: Surface Mount (consistent across all candidates)
RoHS and REACH Compliance: ROHS3 Compliant and REACH Unaffected (maintained across all substitutes)

All identified substitute parts meet these criteria and are qualified for direct replacement in applications designed for the ES2CH.

Engineering Selection Recommendations

ES2CH (Primary Selection)

The ES2CH remains the preferred choice for new designs and ongoing production. It maintains Active product status with Taiwan Semiconductor Corporation, ensuring long-term availability and supply chain stability. The part carries AEC-Q101 automotive qualification, making it suitable for automotive and industrial applications requiring certified components.

ER2C_R1_00001 (Recommended Substitute)

The ER2C_R1_00001 manufactured by Panjit International Inc. is the primary substitute option. This part maintains Active product status and meets all electrical specifications required for direct replacement. The reverse leakage current is 1 µA at 150 V, which is lower than the ES2CH specification of 10 µA, representing improved performance characteristics. Packaging is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations. ROHS3 compliance and REACH Unaffected status are maintained.

ES2C R5G (Secondary Substitute)

The ES2C R5G is a parametric equivalent from Taiwan Semiconductor Corporation with identical electrical specifications to the ES2CH. However, this part has been discontinued at DiGi Electronics, limiting its viability for new procurement. It is listed here for reference in legacy system documentation and for applications where existing inventory remains available. Packaging is supplied in Cut Tape (CT) format.

Compliance and Certification Considerations

All three parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across EU and international markets. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all candidates, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the ER2C_R1_00001 be used as a direct replacement for the ES2CH in automotive applications?

A: Yes. The ER2C_R1_00001 meets all electrical parameters required for direct replacement. However, verify that your application design does not specifically require AEC-Q101 qualification from Taiwan Semiconductor Corporation. The ER2C_R1_00001 is manufactured by Panjit International Inc. and maintains equivalent electrical performance with lower reverse leakage current.

Q: What is the difference between the packaging formats (Cut Tape vs. Tape & Reel)?

A: Cut Tape (CT) packaging is supplied in individual strips suitable for manual or small-batch assembly. Tape & Reel (TR) packaging is supplied on continuous reels optimized for high-speed automated pick-and-place assembly equipment. Both formats contain the same component in the DO-214AA (SMB) package. Select based on your assembly process requirements.

Q: Why is the ES2C R5G listed as discontinued?

A: The ES2C R5G has been discontinued at DiGi Electronics, the primary distribution channel referenced in the product data. This does not indicate the part is obsolete globally, but rather that it is no longer actively stocked through this specific distributor. For legacy system support, verify availability through alternative distribution channels or consider migration to the ER2C_R1_00001.

Q: Are there any thermal or performance differences between the ES2CH and ER2C_R1_00001?

A: Both parts operate across the identical temperature range (-55°C to 150°C junction temperature) and share the same reverse recovery time (35 ns). The ER2C_R1_00001 exhibits lower reverse leakage current (1 µA vs. 10 µA at 150 V), which may provide marginal performance benefits in high-impedance circuit applications. Forward voltage drop and capacitance are identical.

Q: Can these parts be mixed in the same production batch?

A: Yes, provided your design and quality procedures permit cross-manufacturer substitution. All three parts meet identical electrical specifications and package requirements. Document any substitution in your bill of materials and design change records for traceability and future reference.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level is 1 (Unlimited) for all candidates, requiring no special moisture control during storage or assembly. Verify any additional application-specific certifications required by your end-use market or customer specifications.
