FQP6N60C_F080 Equivalent & Substitute Parts

Part Overview

The FQP6N60C_F080 is an N-Channel MOSFET rated for 600V drain-to-source voltage with 5.5A continuous drain current and 125W power dissipation in a Through Hole TO-220-3 package. This device is part of the QFET® series from onsemi and is classified as Obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary for design continuity, procurement alternatives, and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FQP6N60C_F080 is determined by the following critical parameters:

Primary Substitution Criteria:

• Drain to Source Voltage (Vdss): 600V minimum
• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Package / Case: TO-220-3 or compatible TO-220 footprint
• Mounting Type: Through Hole

Secondary Compatibility Factors:

• Current - Continuous Drain (Id): Equal to or greater than 5.5A
• Rds On (Max): Equal to or less than 2Ohm at specified conditions
• Power Dissipation (Max): Equal to or greater than 125W
• Operating Temperature Range: Minimum -55°C to 150°C

The substitute parts listed below meet the primary criteria. Parts with lower current ratings or power dissipation may be used in applications where the full 5.5A rating is not required, provided all voltage and thermal specifications are verified for the specific application.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

The FQP6N60C from Fairchild Semiconductor is a parametric equivalent to the FQP6N60C_F080. Both devices share identical electrical specifications including 5.5A continuous drain current, 2Ohm Rds On, and 125W power dissipation. The Fairchild part is currently Active and available in higher inventory quantities (15,326 pcs), making it the preferred choice for direct substitution in new procurement or design updates.

Similar Alternatives (Reduced Current Rating):

The AOT4N60 from Alpha & Omega Semiconductor Inc. and STP4NK60Z from STMicroelectronics are similar alternatives with reduced current ratings (4A vs. 5.5A) and lower power dissipation. The AOT4N60 is classified as Not For New Designs. The STP4NK60Z is currently Active with the highest inventory availability (45,200 pcs) and features SuperMESH™ technology with lower power dissipation (70W). These parts are suitable for applications where the full 5.5A rating is not required.

Selection should prioritize Active status parts for new designs. The FQP6N60C (Fairchild) provides the closest electrical match. The STP4NK60Z offers the best long-term availability and active support status, with the trade-off of reduced power dissipation capability.

Frequently Asked Questions (FAQ)

Q: Can the FQP6N60C from Fairchild Semiconductor directly replace the FQP6N60C_F080 from onsemi?

A: Yes. Both parts are parametric equivalents with identical Vdss (600V), Id (5.5A), Rds On (2Ohm), and power dissipation (125W) specifications. Both use the TO-220-3 package and share the same QFET® series designation. The Fairchild part is currently Active and available in higher quantities.

Q: Why do the AOT4N60 and STP4NK60Z have lower current ratings than the original part?

A: The AOT4N60 and STP4NK60Z are rated for 4A continuous drain current compared to 5.5A for the FQP6N60C_F080. These parts are classified as similar alternatives rather than direct equivalents. They maintain the same 600V Vdss rating and comparable Rds On characteristics but with reduced power dissipation capability (104W and 70W respectively). Selection depends on the actual current requirements of the application.

Q: Are all substitute parts compatible with the TO-220-3 footprint?

A: All listed substitute parts use TO-220-3 or compatible TO-220 package designations and are Through Hole mounted. They are mechanically and electrically compatible with the same PCB footprint and thermal management approach as the original FQP6N60C_F080.

Q: What is the difference between the FQP6N60C_F080 and FQP6N60C part numbers?

A: The FQP6N60C_F080 is the full part number designation from onsemi, where "_F080" represents the specific manufacturing code or date code variant. The FQP6N60C from Fairchild Semiconductor is the base part number without the manufacturing suffix. Both devices share identical electrical and mechanical specifications.

Q: Should I use the STP4NK60Z for new designs if the FQP6N60C is available?

A: For new designs, prioritize Active status parts. The FQP6N60C (Fairchild) is Active and provides full parametric equivalence to the original part. The STP4NK60Z is also Active but with reduced current and power ratings. Use the STP4NK60Z only if application requirements do not exceed 4A continuous current and 70W power dissipation.

Q: What is the product status significance for component selection?

A: Product status indicates manufacturer support and availability. Active parts receive ongoing support and are recommended for new designs. Obsolete parts are no longer manufactured and may have limited availability. Not For New Designs parts are still available but not recommended for new applications. For the FQP6N60C_F080 (Obsolete), the Active FQP6N60C (Fairchild) or STP4NK60Z (STMicroelectronics) are preferred for long-term design continuity.
