EPC2024 GaNFET N-Channel 40V 60A Equivalent & Substitute Parts

Part Overview

The EPC2024 is an N-Channel GaNFET (Gallium Nitride Field Effect Transistor) rated for 40V drain-to-source voltage with 90A continuous drain current at 25°C. This surface mount die package component operates across a temperature range of -40°C to 150°C junction temperature. The EPC2024 is classified as "Not For New Designs," indicating it has been superseded in the product lifecycle. Identifying equivalent and substitute parts is necessary for ongoing support of existing designs, maintenance of legacy systems, and sourcing continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EPC2024 is determined by strict alignment of the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must maintain the same 40V Vdss rating to ensure safe operation within the original circuit design envelope.

Current Handling Capability: The substitute must support continuous drain current at or above the original specification. The EPC2024 specifies 90A (Ta) at 25°C; substitute parts must not fall below this threshold to maintain thermal and electrical performance margins.

On-Resistance (Rds On): The substitute's maximum on-resistance must not exceed the original specification to prevent increased power dissipation and thermal stress in the application.

Gate-Source Voltage Compatibility: The substitute must operate within the same Vgs range (+6V / -4V) to ensure compatibility with existing gate drive circuitry.

Temperature Operating Range: The substitute must support the full -40°C to 150°C junction temperature range to maintain reliability across all operating conditions.

Package Type: Both the main part and substitute must be surface mount die packages to ensure mechanical and thermal interface compatibility.

Technology Platform: Both parts must utilize GaNFET technology to maintain electrical characteristics and switching performance.

The EPC2067 meets all these criteria and is identified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: EPC2067

The EPC2067 is the manufacturer-recommended substitute for the EPC2024. Both components share identical voltage ratings (40V Vdss), gate-source voltage compatibility (+6V / -4V), and operating temperature range (-40°C to 150°C). Both are RoHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level).

The EPC2067 carries Active product status, ensuring ongoing manufacturer support, availability, and technical documentation. The EPC2024 is designated "Not For New Designs," making the EPC2067 the appropriate choice for design continuity and long-term supply chain stability.

Parameter Considerations:

The EPC2024 specifies 90A continuous drain current, while the EPC2067 specifies 69A. In applications where the full 90A capability is required, the EPC2067 may not provide equivalent current handling. However, the on-resistance specifications remain compatible (1.5 mOhm vs. 1.55 mOhm at 37A, 5V), indicating similar power dissipation characteristics at nominal operating points.

The EPC2067 exhibits higher input capacitance (3267 pF vs. 2100 pF at 20V), which may affect gate drive timing and switching speed in high-frequency applications. Circuit validation is necessary to confirm performance equivalence in applications sensitive to input capacitance.

Compliance and Regulatory:

Both parts maintain identical compliance certifications (RoHS3, REACH Unaffected, EAR99 ECCN classification, HTSUS 8541.29.0040). No regulatory or environmental qualification barriers exist for substitution.

Frequently Asked Questions (FAQ)

Q: Can the EPC2067 directly replace the EPC2024 in all applications?

A: The EPC2067 is electrically compatible with the EPC2024 across voltage rating, gate-source voltage range, and operating temperature. However, the EPC2067 specifies 69A continuous drain current compared to the EPC2024's 90A. Applications requiring the full 90A capability must evaluate whether the substitute's current rating is sufficient. The on-resistance specifications are nearly identical (1.5 mOhm vs. 1.55 mOhm), supporting equivalent power dissipation at standard operating points.

Q: What is the significance of the higher input capacitance in the EPC2067?

A: The EPC2067 exhibits 3267 pF input capacitance versus 2100 pF in the EPC2024 at 20V. Higher input capacitance increases gate charge requirements and may extend switching transition times. Applications with tight switching frequency or gate drive current constraints should evaluate the impact on circuit performance and thermal management.

Q: Are there packaging differences between the EPC2024 and EPC2067?

A: Both parts are surface mount die packages. The EPC2024 is supplied in Cut Tape (CT) and Digi-Reel® packaging, while the EPC2067 is supplied in Tape & Reel (TR) packaging. The die package itself is identical; packaging format differences relate to supply and handling only.

Q: Why is the EPC2024 marked "Not For New Designs"?

A: The "Not For New Designs" designation indicates the EPC2024 has been superseded in the manufacturer's product lifecycle. The EPC2067, classified as Active, represents the current generation equivalent. For new designs, the EPC2067 is the recommended selection. For existing designs using the EPC2024, the EPC2067 provides a qualified substitute path.

Q: Are there any compliance or regulatory differences between the two parts?

A: No. Both the EPC2024 and EPC2067 are RoHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.29.0040) classifications. No regulatory barriers exist for substitution.

Q: What inventory status should be considered when selecting between these parts?

A: The EPC2024 has 1230 pieces in stock (new original), while the EPC2067 has 5643 pieces in stock. The EPC2067's higher inventory level and Active product status support longer-term availability and supply chain continuity.

Q: How do the gate-source threshold voltages compare?

A: Both parts specify 2.5V maximum gate-source threshold voltage. The EPC2024 measures this at 19mA, while the EPC2067 measures at 18mA. This minor difference in measurement current does not affect gate drive circuit compatibility, as both operate within the same +6V / -4V gate-source voltage range.
