EPC2020 Equivalent & Substitute Parts Reference

Part Overview

The EPC2020 is an N-Channel GaNFET (Gallium Nitride Field Effect Transistor) rated for 60V drain-to-source voltage with 90A continuous drain current at 25°C. This component is supplied as a surface mount die in Cut Tape and Digi-Reel packaging formats. The EPC2020 is classified as "Not For New Designs," indicating that this part number is obsolete or transitioning out of active production. Identifying suitable substitute components is necessary for ongoing maintenance, repair, and redesign of existing applications utilizing this GaNFET technology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPC2020 GaNFET is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• FET Type: N-Channel configuration required
• Technology: GaNFET (Gallium Nitride) maintained
• Drain-to-Source Voltage (Vdss): Substitute must equal or exceed 60V rating
• Continuous Drain Current (Id): Substitute must meet or exceed 90A at 25°C
• Gate Threshold Voltage (Vgs(th)): Must remain within compatible range (2.5V specification)
• Drive Voltage: 5V gate drive compatibility required
• Operating Temperature Range: Must support -40°C to +150°C (TJ)

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount required
• Series: eGaN® technology family
• RoHS Compliance: ROHS3 Compliant status required
• REACH Status: REACH Unaffected designation required

The EPC2302 qualifies as a substitute based on these parameters. While the EPC2302 features higher voltage rating (100V vs. 60V) and increased current capability (101A vs. 90A), these represent performance enhancements rather than incompatibilities. The lower on-resistance (1.8 mOhm vs. 2.2 mOhm) and higher gate charge (23 nC vs. 16 nC) are direct consequences of the improved specifications. Package format differs (7-QFN vs. Die), requiring circuit board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The EPC2020 carries "Not For New Designs" status, indicating manufacturer transition away from this part number. The EPC2302 is classified as "Active," ensuring ongoing manufacturer support, availability, and technical documentation updates.

Compliance and Certification: Both the EPC2020 and EPC2302 maintain ROHS3 Compliant and REACH Unaffected designations, satisfying regulatory requirements for industrial and commercial applications. No compliance barriers exist for substitution.

Electrical Performance: The EPC2302 provides enhanced electrical specifications within the same GaNFET technology platform. The 100V voltage rating accommodates 60V application requirements with design margin. The 101A current rating exceeds the 90A requirement. Lower on-resistance (1.8 mOhm vs. 2.2 mOhm) reduces power dissipation and improves thermal performance in equivalent operating conditions.

Gate Drive Compatibility: Both devices operate with 5V gate drive voltage and maintain identical gate threshold voltage (2.5V). The EPC2302 exhibits higher gate charge (23 nC vs. 16 nC), requiring verification that existing gate driver circuits possess sufficient charge delivery capability. Driver output impedance and switching frequency must be evaluated against the increased gate charge specification.

Packaging and Integration: The EPC2020 is supplied as a bare die, while the EPC2302 is packaged in 7-QFN (3x5) format. This fundamental difference necessitates circuit board layout redesign, including die attachment methodology, wire bonding or solder connection techniques, and thermal management approach. The packaged format of EPC2302 may simplify integration compared to bare die handling.

Moisture Sensitivity: The EPC2020 carries MSL 1 (Unlimited), while EPC2302 is rated MSL 2 (1 Year). The EPC2302 requires controlled storage and handling within one year of packaging. Manufacturing and assembly processes must accommodate this moisture sensitivity level.

Frequently Asked Questions (FAQ)

Q: Can the EPC2302 directly replace the EPC2020 in existing circuit designs?

A: Electrical substitution is feasible based on voltage, current, and gate drive specifications. However, the package format change from Die to 7-QFN (3x5) requires circuit board layout modification. Gate driver circuits must be evaluated for compatibility with the increased gate charge (23 nC vs. 16 nC) to ensure proper switching performance.

Q: What are the key differences between EPC2020 and EPC2302?

A: The EPC2302 provides higher voltage rating (100V vs. 60V), increased current capability (101A vs. 90A), and lower on-resistance (1.8 mOhm vs. 2.2 mOhm). The EPC2302 is packaged in 7-QFN format versus bare die. The EPC2302 is actively supported by the manufacturer, while EPC2020 is not recommended for new designs. Gate charge is higher (23 nC vs. 16 nC), and moisture sensitivity level differs (MSL 2 vs. MSL 1).

Q: Is the higher voltage rating of EPC2302 (100V vs. 60V) a concern for 60V applications?

A: No. Higher voltage rating provides design margin and does not create incompatibility. The EPC2302 is fully suitable for applications rated at 60V or lower. The device will operate safely within the lower voltage envelope.

Q: What impact does the increased gate charge of EPC2302 have on circuit performance?

A: Gate charge (23 nC vs. 16 nC) affects switching speed and gate driver power dissipation. Existing gate driver circuits must deliver sufficient charge within the required switching time. Driver output impedance, supply voltage, and switching frequency should be evaluated. Higher gate charge may increase switching losses in high-frequency applications.

Q: Does the package format change from Die to 7-QFN require complete circuit redesign?

A: The package format change requires circuit board layout modification, including footprint redesign, trace routing, and thermal management approach. Electrical functionality remains compatible. The 7-QFN package may simplify manufacturing compared to bare die assembly, potentially reducing integration complexity.

Q: Are there any compliance or regulatory differences between EPC2020 and EPC2302?

A: Both devices maintain ROHS3 Compliant and REACH Unaffected status. No regulatory barriers exist for substitution. Both devices are suitable for industrial and commercial applications subject to the same compliance frameworks.

Q: What is the significance of the "Not For New Designs" status of EPC2020?

A: This designation indicates the manufacturer is transitioning away from this part number. Existing inventory may become limited. The EPC2302, classified as "Active," ensures ongoing availability, technical support, and documentation updates from the manufacturer.

Q: How does the moisture sensitivity level (MSL) difference affect handling and storage?

A: EPC2020 (MSL 1) has unlimited shelf life under standard conditions. EPC2302 (MSL 2) requires controlled storage and must be used within one year of packaging. Manufacturing and assembly processes must implement moisture control measures, including dry storage, desiccant packaging, and bake-out procedures if the device is exposed to moisture.
