EPC2015C GaNFET N-Channel 40V 53A Die Equivalent & Substitute Parts

Part Overview

The EPC2015C is an N-Channel GaNFET (Gallium Nitride Field Effect Transistor) die rated for 40V drain-to-source voltage with 53A continuous drain current at 25°C. This component is designed for surface mount applications in high-efficiency power conversion circuits. The EPC2015C carries a "Not For New Designs" product status, indicating that EPC has transitioned this part from active production. For new circuit designs and ongoing production requirements, equivalent substitute parts with compatible electrical and mechanical specifications are necessary to ensure design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the EPC2015C is determined by strict alignment of electrical and mechanical parameters within the GaNFET N-Channel device category. The following criteria establish substitution validity:

Primary Substitution Criteria:

• Drain to Source Voltage (Vdss): Must equal 40V
• FET Type: Must be N-Channel
• Technology: Must be GaNFET (Gallium Nitride)
• Package Type: Must be Die (surface mount)
• Gate Threshold Voltage (Vgs(th)): Must be compatible at specified test conditions
• Gate Voltage Range (Vgs Max): Must accommodate +6V / -4V operation
• Operating Temperature Range: Must support -40°C to 150°C

Secondary Compatibility Parameters:

• Continuous Drain Current (Id): Substitute must meet or exceed application requirements
• On-State Resistance (Rds On): Lower or equal values are acceptable
• Gate Charge (Qg): Lower values indicate improved switching performance
• Input Capacitance (Ciss): Lower values indicate reduced gate drive requirements

The EPC2055 qualifies as a manufacturer-recommended substitute based on matching Vdss (40V), FET type (N-Channel), technology (GaNFET), package (Die), gate voltage range (+6V / -4V), and operating temperature range (-40°C to 150°C). The EPC2055 operates at 29A continuous drain current, which is lower than the EPC2015C's 53A rating; therefore, application current requirements must not exceed 29A for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The EPC2055 is the manufacturer-recommended substitute and carries Active product status, making it the appropriate choice for new circuit designs. This part maintains full electrical compatibility with the EPC2015C across all critical parameters: Vdss, gate voltage range, operating temperature, and package type. Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance in manufacturing and end-use applications.

Current Rating Consideration: The EPC2055 is rated for 29A continuous drain current compared to the EPC2015C's 53A. Substitution is valid only when the application's maximum continuous drain current requirement does not exceed 29A at 25°C. For applications requiring drain currents above 29A, the EPC2015C must be retained or alternative higher-current GaNFET devices must be evaluated.

Supply Chain and Production: The EPC2015C is designated "Not For New Designs," indicating end-of-life status. The EPC2055 with Active status provides long-term supply availability and production support. Existing designs using the EPC2015C should transition to the EPC2055 during the next design revision cycle if current requirements permit.

Compliance and Certifications: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. No additional qualification or testing is required from a regulatory or environmental standpoint when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can the EPC2055 directly replace the EPC2015C in existing designs?

A: Direct substitution is valid only if the application's continuous drain current requirement does not exceed 29A at 25°C. The EPC2055 is rated for 29A, while the EPC2015C is rated for 53A. If the existing design operates below 29A, the EPC2055 is a direct electrical and mechanical replacement. If the design requires higher current, substitution is not valid.

Q: What are the key electrical differences between these parts?

A: The primary difference is continuous drain current rating: EPC2015C at 53A versus EPC2055 at 29A. The EPC2055 exhibits slightly lower on-state resistance (3.6 mOhm at 15A versus 4 mOhm at 33A) and lower input capacitance (1111 pF versus 1180 pF). Gate charge is nearly identical (8.5 nC versus 8.7 nC). Both parts share identical Vdss (40V), gate voltage range (+6V / -4V), and operating temperature range (-40°C to 150°C).

Q: Are there any package or mounting differences?

A: No. Both the EPC2015C and EPC2055 are supplied as surface mount dies with identical package type. No PCB layout modifications or assembly process changes are required for substitution.

Q: Why is the EPC2015C marked "Not For New Designs"?

A: This designation indicates that EPC has transitioned the EPC2015C to end-of-life status and is no longer recommending it for new circuit designs. The EPC2055, with Active product status, is the current production alternative and should be used for all new designs within the current rating constraints.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the EPC2015C and EPC2055 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. No additional compliance qualification is required when substituting between these parts.

Q: What should I do if my application requires more than 29A continuous drain current?

A: If your application requires continuous drain current above 29A, the EPC2055 is not a valid substitute. You must retain the EPC2015C if inventory is available, or evaluate alternative GaNFET N-Channel devices with higher current ratings and matching Vdss (40V) and package type (Die) specifications.
