IRFSL4227PBF N-Channel MOSFET 200V 62A TO-262 Equivalent & Substitute Parts

Part Overview

The IRFSL4227PBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 200V drain-to-source voltage and 62A continuous drain current in a Through Hole TO-262 package. This device is classified as Obsolete product status. Due to obsolescence and limited availability, identifying equivalent substitute parts with compatible electrical and mechanical specifications is necessary for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRFSL4227PBF is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) must equal or exceed 200V
• Continuous Drain Current (Id) must equal or exceed 62A at 25°C
• On-State Resistance (Rds On) must not exceed the original specification to maintain thermal performance
• Gate Threshold Voltage (Vgs(th)) must be compatible with existing drive circuitry
• Gate Charge (Qg) affects switching speed and driver requirements
• Power Dissipation capability must support thermal design requirements

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (required)
• Package: TO-262-3 Long Leads, I2PAK, or TO-262AA (pin-compatible)

The substitute part IPI200N25N3GAKSA1 meets these criteria with enhanced voltage rating (250V) and improved on-state resistance characteristics while maintaining package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The IPI200N25N3GAKSA1 is a direct substitute for the IRFSL4227PBF based on the following engineering factors:

1. Electrical Performance: The substitute exceeds minimum requirements with 250V Vdss (vs. 200V required), 64A Id (vs. 62A required), and superior on-state resistance of 20 mOhm (vs. 26 mOhm). Lower gate charge (86 nC vs. 98 nC) reduces driver stress.

2. Package Compatibility: Both devices use TO-262-3 Long Leads packaging with identical pin configuration, enabling direct PCB footprint compatibility without layout modifications.

3. Thermal Design: The substitute provides adequate power dissipation at 300W, sufficient for applications designed around the original 330W specification when thermal management is properly implemented.

4. Compliance: Both parts maintain identical REACH Unaffected status, EAR99 ECCN classification, and MSL 1 rating, ensuring regulatory and supply chain compatibility.

5. Temperature Range: The substitute extends the lower operating limit to -55°C, providing enhanced cold-temperature performance compared to the original -40°C specification.

Design Considerations:

Gate voltage compatibility requires attention: the substitute has Vgs(th) of 4V (vs. 5V) and maximum Vgs of ±20V (vs. ±30V). Existing gate drive circuits must operate within ±20V limits. Input capacitance increases from 4600 pF to 7100 pF, which may require gate driver current adjustment for optimal switching performance.

Frequently Asked Questions (FAQ)

Q: Can the IPI200N25N3GAKSA1 directly replace the IRFSL4227PBF without PCB modifications?

A: Yes. Both devices use the TO-262-3 package with identical pin configuration and lead spacing. No PCB layout changes are required for mechanical installation.

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

A: The substitute offers higher voltage rating (250V vs. 200V), improved on-state resistance (20 mOhm vs. 26 mOhm), lower gate charge (86 nC vs. 98 nC), and extended low-temperature operation (-55°C vs. -40°C). Maximum gate voltage is reduced from ±30V to ±20V.

Q: Does the lower maximum gate voltage (±20V vs. ±30V) affect compatibility?

A: This parameter affects gate drive circuit design. If the original circuit applies gate voltages exceeding ±20V, the substitute cannot be used without gate drive circuit modification. Standard gate drive circuits operating within ±15V are compatible with both parts.

Q: How does the increased input capacitance (7100 pF vs. 4600 pF) impact circuit performance?

A: Higher input capacitance increases gate charge requirements during switching transitions. Gate driver current capability must be verified to ensure adequate charging/discharging speed. This may require gate resistor adjustment or driver upgrade in high-frequency switching applications.

Q: Are both parts subject to the same regulatory requirements?

A: Yes. Both maintain REACH Unaffected status, EAR99 ECCN classification, and MSL 1 moisture sensitivity rating. No additional compliance documentation is required for substitution.

Q: What is the inventory status for the substitute part?

A: The IPI200N25N3GAKSA1 has 631 pieces in stock as new original inventory. Both the original IRFSL4227PBF (7617 pieces) and substitute are currently available.

Q: Can the substitute handle the same power dissipation as the original?

A: The substitute is rated for 300W (Tc) versus the original 330W (Tc). For applications requiring the full 330W dissipation capability, thermal management design must be reviewed. The improved on-state resistance (20 mOhm vs. 26 mOhm) partially compensates for the lower power rating through reduced conduction losses.
