EPC2025 GaNFET N-Channel 300V 4A Die - Equivalent & Substitute Parts

Part Overview

The EPC2025 is an N-Channel GaNFET (Gallium Nitride Field Effect Transistor) rated for 300V drain-to-source voltage and 4A continuous drain current at 25°C. This component is supplied as a surface mount die in the eGaN® series from EPC (Efficient Power Conversion). The EPC2025 is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility within the specified parameter ranges while meeting current product availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPC2025 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• FET Type: N-Channel
• Technology: GaNFET (Gallium Nitride)
• Drain to Source Voltage (Vdss): Must equal or exceed 300V
• Current - Continuous Drain (Id) @ 25°C: Must equal or exceed 4A
• Drive Voltage (Max Rds On): Must be compatible at 5V
• Gate Threshold Voltage (Vgs(th)): Must be within acceptable range
• Gate Voltage Limits (Vgs Max): Must be compatible with +6V, -4V specification
• Mounting Type: Surface Mount Die
• Operating Temperature Range: Must support -40°C to 150°C (TJ)
• Compliance: RoHS3 Compliant, MSL 1

The EPC2050 qualifies as a manufacturer-recommended substitute because it exceeds the minimum electrical requirements of the EPC2025 while maintaining identical gate voltage specifications, compatible threshold voltage characteristics, and equivalent compliance certifications. Both devices are eGaN® series components with identical mounting type (Surface Mount Die) and operating temperature range.

Engineering Selection Recommendations

EPC2050 as Primary Substitute:

The EPC2050 is the manufacturer-recommended substitute for the obsolete EPC2025. Selection of the EPC2050 is based on the following engineering factors:

Product Status: The EPC2025 is classified as obsolete, whereas the EPC2050 is active. Active product status ensures ongoing availability, manufacturing support, and compliance with current regulatory requirements.

Electrical Compatibility: The EPC2050 exceeds the minimum electrical specifications of the EPC2025 across all critical parameters. The drain-to-source voltage rating increases from 300V to 350V, and continuous drain current increases from 4A to 6.3A. These enhancements provide design margin and allow the EPC2050 to function in applications originally designed for the EPC2025 without performance degradation.

Gate Voltage Compatibility: Both devices share identical gate voltage specifications (Vgs Max: +6V, -4V) and gate threshold voltage (Vgs(th) Max: 2.5V @ 1mA), ensuring direct compatibility with existing gate drive circuits and control electronics.

Compliance and Certifications: Both the EPC2025 and EPC2050 are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Both devices are REACH unaffected and classified under ECCN EAR99. The EPC2050 maintains full compliance equivalence with the obsolete part.

Thermal Performance: Both devices support the identical operating temperature range of -40°C to 150°C (TJ), ensuring thermal compatibility in existing thermal management designs.

Die Package Compatibility: Both devices are supplied as surface mount dies, maintaining identical mechanical and assembly compatibility.

Frequently Asked Questions (FAQ)

Q1: Can the EPC2050 directly replace the EPC2025 in existing designs?

A: Yes. The EPC2050 is the manufacturer-recommended substitute and exceeds all minimum electrical specifications of the EPC2025. Gate voltage specifications are identical, and both devices support the same operating temperature range. No circuit modifications are required for direct substitution.

Q2: What are the key differences between the EPC2025 and EPC2050?

A: The EPC2050 provides higher voltage rating (350V vs. 300V), higher continuous drain current (6.3A vs. 4A), and higher input capacitance (628 pF vs. 194 pF). The EPC2050 is active product status, whereas the EPC2025 is obsolete. On-resistance (Rds On) is specified at higher current levels for the EPC2050 (6A vs. 3A).

Q3: Are there any compliance or certification differences between these parts?

A: No. Both the EPC2025 and EPC2050 are RoHS3 compliant, carry MSL 1 (Unlimited) rating, are REACH unaffected, and share the same ECCN classification (EAR99). Compliance equivalence is maintained.

Q4: Why is the EPC2025 obsolete?

A: The EPC2025 has been superseded by the EPC2050, which offers improved electrical performance and higher current capability. The manufacturer recommends the EPC2050 for all new designs and as the substitute for existing EPC2025 applications.

Q5: What is the impact of higher input capacitance in the EPC2050?

A: The EPC2050 has higher input capacitance (628 pF @ 280V vs. 194 pF @ 240V). This parameter affects gate drive circuit design and switching speed characteristics. Applications with tight switching frequency requirements should evaluate gate drive capability, though the identical gate voltage specifications ensure compatibility with standard drive circuits.

Q6: Are there inventory considerations for the EPC2025 vs. EPC2050?

A: The EPC2025 has 786 pieces in stock as new original inventory. The EPC2050 has significantly higher availability with 17,144 pieces in stock. For new production and long-term supply chain planning, the EPC2050 is the recommended choice due to superior availability and active product status.

Q7: Can the EPC2050 be used in applications requiring exactly 300V rating?

A: Yes. The EPC2050 is rated for 350V, which exceeds the 300V requirement. Higher voltage rating provides design margin and does not create incompatibility in 300V applications. The device will operate safely within the lower voltage specification.

Q8: What packaging format is used for both parts?

A: Both the EPC2025 and EPC2050 are supplied as surface mount dies. The EPC2050 is available in Tape & Reel (TR) packaging format. Both maintain identical die package specifications for assembly compatibility.
