IXFC12N80P Equivalent & Substitute Parts

Part Overview

The IXFC12N80P is an N-Channel MOSFET rated for 800V drain-to-source voltage with 7A continuous drain current at 25°C. This device is packaged in the ISOPLUS220™ through-hole format and is designed for high-voltage switching applications. The part is currently classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXFC12N80P is based on electrical parameter equivalence within the constraints of the MOSFET category. The primary substitution criteria are:

Electrical Equivalence Requirements:

• Drain-to-source voltage rating (Vdss) must equal or exceed 800V
• Continuous drain current (Id) must equal or exceed 7A at 25°C
• Gate threshold voltage (Vgs(th)) must be compatible with existing drive circuitry
• Maximum gate voltage (Vgs) must be ±30V or greater
• Operating temperature range must encompass -55°C to 150°C

Mechanical Compatibility:

• Through-hole mounting type required
• Package must accommodate existing PCB footprint or allow mechanical adaptation

The IXFP7N80P meets these electrical requirements with identical voltage and current ratings. However, the package differs from the original ISOPLUS220™ format, changing from ISOPLUS220™ to TO-220-3. This substitution is valid for applications where the TO-220-3 package footprint can be accommodated on the PCB or through mechanical adaptation.

Engineering Selection Recommendations

IXFC12N80P (Original Part):

• Product Status: Obsolete
• Availability: 936 pieces in stock
• REACH Status: REACH Unaffected
• Compliance: ECCN EAR99

IXFP7N80P (Substitute Part):

• Product Status: Active
• Availability: 2300 pieces in stock
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Compliance: ECCN EAR99

The IXFP7N80P is the recommended substitute for the obsolete IXFC12N80P. Both devices are manufactured by IXYS and belong to the HiPerFET™ series. The substitute part maintains electrical equivalence across all critical parameters: 800V Vdss, 7A continuous drain current, and compatible gate drive characteristics. The IXFP7N80P offers superior performance characteristics, including lower on-resistance (1.44 mOhm vs. 930 mOhm at different measurement points), reduced gate charge (32 nC vs. 51 nC), and higher power dissipation capability (200W vs. 120W).

The primary design consideration is the package change from ISOPLUS220™ to TO-220-3. Both are through-hole packages; however, the footprint and thermal characteristics differ. PCB layout modifications may be required to accommodate the TO-220-3 package. The TO-220-3 package provides improved thermal performance due to its larger surface area and standardized mounting interface.

Both parts maintain identical operating temperature ranges (-55°C to 150°C) and maximum gate voltage ratings (±30V), ensuring compatibility with existing drive and protection circuitry.

Frequently Asked Questions (FAQ)

Q: Can the IXFP7N80P directly replace the IXFC12N80P without circuit modifications?

A: The IXFP7N80P is electrically equivalent to the IXFC12N80P for all critical switching and conduction parameters. However, PCB layout modifications are required due to the package change from ISOPLUS220™ to TO-220-3. The footprint, mounting hole positions, and thermal interface differ between these packages. Mechanical adaptation or PCB redesign is necessary.

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

A: The parts are electrically equivalent in voltage and current ratings. Differences exist in secondary characteristics: the IXFP7N80P has lower on-resistance (1.44 mOhm vs. 930 mOhm), lower gate charge (32 nC vs. 51 nC), lower input capacitance (1890 pF vs. 2800 pF), and higher power dissipation capability (200W vs. 120W). These differences represent performance improvements in the substitute part.

Q: Are there thermal management implications when switching from ISOPLUS220™ to TO-220-3?

A: The TO-220-3 package provides a larger surface area and standardized mounting interface compared to ISOPLUS220™. The increased power dissipation rating (200W vs. 120W) indicates improved thermal performance. Thermal management design may be simplified with the TO-220-3 package due to its widespread use and standardized heatsink compatibility.

Q: What is the moisture sensitivity level for both parts?

A: Both the IXFC12N80P and IXFP7N80P have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Are both parts compliant with environmental regulations?

A: Both parts have REACH Unaffected status and ECCN EAR99 classification. The IXFP7N80P additionally carries ROHS3 Compliant certification, indicating compliance with Restriction of Hazardous Substances Directive requirements.

Q: What is the availability status of each part?

A: The IXFC12N80P (obsolete) has 936 pieces in stock. The IXFP7N80P (active) has 2300 pieces in stock, providing greater long-term availability and supply chain security.

Q: Can the IXFP7N80P be used in new designs?

A: Yes. The IXFP7N80P is classified as an active product with ROHS3 compliance, making it suitable for new designs. The active product status ensures continued manufacturer support and availability.
