Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPC2021 is determined by strict alignment of electrical and mechanical parameters within the GaNFET N-Channel transistor category. The following criteria establish substitution validity:

Electrical Compatibility Requirements:

• Technology: GaNFET (Gallium Nitride) N-Channel FET
• Drain-to-Source Voltage (Vdss): Must equal or exceed 80V
• Continuous Drain Current (Id): Must equal or exceed 90A at 25°C
• Gate Threshold Voltage (Vgs(th)): Must be compatible at specified test conditions
• Gate-Source Voltage Range (Vgs): Must accommodate ±5V to ±6V operation
• Operating Temperature Range: Must span -40°C to 150°C (TJ)

Mechanical and Compliance Requirements:

• Mounting Type: Surface Mount
• Series: eGaN® technology family
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level: Acceptable for production environments

The EPC2302 qualifies as a manufacturer-recommended substitute based on these criteria. While the EPC2302 operates at a higher voltage rating (100V vs. 80V) and delivers increased current capacity (101A vs. 90A), it maintains full backward compatibility with the EPC2021 in applications designed for 80V operation. The EPC2302 exhibits superior on-resistance characteristics (1.8 mOhm vs. 2.5 mOhm) and higher gate charge (23 nC vs. 15 nC), reflecting its enhanced performance envelope.

Parameter Comparison

Engineering Selection Recommendations

The EPC2021 is designated "Not For New Designs," indicating that this part has reached end-of-life status within the manufacturer's product portfolio. For applications currently utilizing the EPC2021, the EPC2302 is the manufacturer-recommended substitute and is classified as "Active" product status, ensuring long-term availability and ongoing technical support.

The EPC2302 provides direct functional replacement with enhanced electrical performance. The higher voltage rating (100V) and increased current capacity (101A) establish a superset of the EPC2021 specifications, ensuring that any circuit designed for 80V/90A operation will function within the EPC2302 operating envelope. The improved on-resistance (1.8 mOhm vs. 2.5 mOhm) reduces power dissipation and thermal stress in equivalent applications.

Both parts maintain identical gate threshold voltage specifications (2.5V @ 14mA), gate-source voltage ranges (±6V, -4V), and operating temperature ranges (-40°C to 150°C TJ), confirming gate drive circuit compatibility. Both components are ROHS3 Compliant and REACH Unaffected, satisfying regulatory requirements for current manufacturing environments.

The EPC2302 carries Moisture Sensitivity Level (MSL) 2 (1 Year) compared to the EPC2021 MSL 1 (Unlimited), requiring standard moisture control procedures during storage and handling consistent with industry practice for surface mount components.

Frequently Asked Questions (FAQ)

Q: Can the EPC2302 directly replace the EPC2021 in existing circuit designs?

A: Yes. The EPC2302 is the manufacturer-recommended substitute and provides full backward compatibility. The higher voltage rating (100V vs. 80V) and increased current capacity (101A vs. 90A) ensure operation within the original design specifications. Gate drive requirements, threshold voltage, and operating temperature ranges are identical between the two parts.

Q: What are the key differences between the EPC2021 and EPC2302?

A: The EPC2302 offers superior electrical performance with lower on-resistance (1.8 mOhm vs. 2.5 mOhm), higher voltage rating (100V vs. 80V), and increased current capacity (101A vs. 90A). The EPC2302 is Active product status, ensuring continued availability, while the EPC2021 is Not For New Designs. Both parts share identical gate threshold voltage, gate-source voltage range, and operating temperature specifications.

Q: Are there package differences between these parts?

A: Yes. The EPC2021 is supplied as a die in Tape & Reel (TR) packaging. The EPC2302 is supplied in 7-QFN (3x5) package format in Cut Tape (CT) and Digi-Reel® packaging. Circuit board layout and assembly processes must accommodate the different package geometries.

Q: What is the significance of the "Not For New Designs" status on the EPC2021?

A: This designation indicates that the EPC2021 has reached end-of-life within the manufacturer's product roadmap. New circuit designs should utilize the EPC2302 or other active-status alternatives. Existing designs using the EPC2021 should transition to the EPC2302 to ensure long-term component availability and manufacturing support.

Q: Are the gate charge specifications compatible between these parts?

A: Both parts share identical gate threshold voltage (2.5V @ 14mA) and gate-source voltage range (+6V, -4V). However, the EPC2302 exhibits higher gate charge (23 nC vs. 15 nC @ 5V), requiring gate drive circuits capable of supplying the increased charge. Existing gate drive designs must be verified for compatibility with the higher gate charge specification.

Q: What moisture handling procedures apply to the EPC2302?

A: The EPC2302 carries Moisture Sensitivity Level (MSL) 2 (1 Year), requiring standard moisture control during storage and handling. Components must be stored in dry conditions and handled according to IPC-A-610 standards for surface mount assembly. The EPC2021 carries MSL 1 (Unlimited), permitting less stringent moisture control.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the EPC2021 and EPC2302 are ROHS3 Compliant and REACH Unaffected, satisfying regulatory requirements for manufacturing in current regulatory environments. Both parts carry identical ECCN (EAR99) and HTSUS (8541.29.0040) classifications.
