EPC2029 Equivalent & Substitute Parts Reference

Part Overview

The EPC2029 is an N-Channel GaNFET (Gallium Nitride) transistor rated for 80V drain-to-source voltage with 48A continuous drain current at 25°C. This device is packaged as a surface mount die and is designed for high-efficiency power conversion applications. The EPC2029 carries a product status of "Not For New Designs," indicating that EPC has transitioned this part to end-of-life status. For new circuit designs and ongoing production requirements, identifying functionally equivalent substitute parts is necessary to ensure design continuity and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPC2029 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Voltage Rating: The substitute must maintain the same 80V Vdss rating to ensure safe operation within the same circuit topology.

Current Capability: The substitute must support equal or greater continuous drain current at 25°C. The EPC2029 specifies 48A; substitutes rated at 48A or higher are acceptable.

On-Resistance Characteristics: The substitute must demonstrate on-resistance performance compatible with the EPC2029's 3.2mOhm specification at the rated drive voltage of 5V. Substitutes with equal or lower on-resistance values are acceptable.

Gate Threshold Voltage: The substitute must operate within the same Vgs(th) range (2.5V @ 12mA) to ensure compatible gate drive circuitry.

Gate Charge and Input Capacitance: These parameters must remain within acceptable ranges to maintain switching performance and gate drive requirements.

Package and Mounting: The substitute must be supplied as a surface mount die to maintain mechanical and thermal compatibility.

Technology Platform: The substitute must utilize GaNFET technology within the eGaN® series to ensure consistent performance characteristics.

Compliance and Status: The substitute should carry Active product status and maintain RoHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

The EPC2065 is the qualified substitute for the EPC2029 based on the following engineering criteria:

Voltage and Current Compatibility: Both devices share an 80V Vdss rating. The EPC2065 provides 60A continuous drain current, exceeding the EPC2029's 48A specification. This higher current rating ensures the substitute can handle the same or greater load conditions without thermal stress.

On-Resistance Performance: The EPC2065 exhibits 3.6mOhm on-resistance at 25A and 5V drive voltage, compared to the EPC2029's 3.2mOhm at 30A and 5V. The on-resistance values are comparable and within acceptable engineering tolerance for equivalent substitution in power conversion circuits.

Gate Drive Compatibility: Both devices maintain a 2.5V gate threshold voltage, ensuring existing gate drive circuits require no modification. Gate charge specifications (13nC for EPC2029 versus 12.2nC for EPC2065) are nearly identical, confirming compatible switching performance.

Thermal and Electrical Characteristics: Input capacitance values (1410pF versus 1449pF) and operating temperature ranges (-40°C to 150°C) are equivalent, ensuring thermal management and switching dynamics remain consistent.

Product Status and Compliance: The EPC2065 carries Active product status, ensuring long-term availability and supply chain continuity. Both devices maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for new designs.

Package Compatibility: Both devices are supplied as surface mount dies, maintaining mechanical and thermal interface compatibility with existing circuit layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the EPC2065 directly replace the EPC2029 in existing designs?

A: Yes. The EPC2065 meets all critical electrical parameters for direct substitution. Both devices share identical voltage ratings (80V), compatible current ratings (60A versus 48A), equivalent on-resistance characteristics, and matching gate drive requirements. No circuit modifications are required.

Q: Why is the EPC2029 marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that EPC has transitioned this part to end-of-life. New circuit designs should utilize the EPC2065, which carries Active product status and ensures long-term supply availability.

Q: Are there differences in on-resistance between the two devices?

A: The EPC2029 specifies 3.2mOhm on-resistance at 30A and 5V drive voltage. The EPC2065 specifies 3.6mOhm at 25A and 5V drive voltage. These values are comparable and within acceptable engineering tolerance for equivalent substitution. The EPC2065's higher current rating (60A) provides additional design margin.

Q: Do gate drive circuits require modification when switching from EPC2029 to EPC2065?

A: No. Both devices maintain identical gate threshold voltage (2.5V) and nearly identical gate charge specifications (13nC versus 12.2nC). Existing gate drive circuits operate without modification.

Q: Are both devices available in the same package?

A: Yes. Both the EPC2029 and EPC2065 are supplied as surface mount dies, maintaining identical mechanical and thermal interface compatibility.

Q: What is the inventory status of these devices?

A: The EPC2029 has 46,860 pieces in stock as new original inventory. The EPC2065 has 2,000 pieces in stock as new original inventory. For long-term production requirements, the EPC2065 is the recommended choice due to its Active product status.

Q: Do both devices meet the same regulatory compliance standards?

A: Yes. Both the EPC2029 and EPC2065 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
