STF26N60M2 Equivalent & Substitute Parts

Part Overview

The STF26N60M2 is an N-Channel 600V 20A MOSFET manufactured by STMicroelectronics in the MDmesh™ series. This device is packaged in TO-220FP through-hole configuration and is rated for 30W power dissipation at case temperature. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary device becomes unavailable, when design requirements demand alternative electrical characteristics, or when supply chain optimization requires component standardization across manufacturing facilities.

Substitute Part Grouping Explanation

Substitution eligibility for the STF26N60M2 is determined by the following critical parameters:

Mandatory Matching Criteria:

Drain to Source Voltage (Vdss): 600V minimum
Continuous Drain Current (Id): 20A or greater at 25°C
Gate-Source Voltage Rating (Vgs): ±20V or greater
Mounting Type: Through Hole
Package Family: TO-220 variants (TO-220F, TO-220FP, TO-220FM, TO-220SIS)
Operating Temperature Range: -55°C to 150°C minimum
RoHS3 Compliance: Required

Flexible Parameters (Allow Variation):

Rds On (Max): May vary within application thermal limits
Power Dissipation: May exceed 30W specification
Gate Charge (Qg): May vary without affecting substitution validity
Input Capacitance (Ciss): May vary without affecting substitution validity
Product Status: Active or Not For New Designs both acceptable for equivalent substitution

The three substitute parts listed below satisfy all mandatory matching criteria and are therefore electrically and mechanically compatible with the STF26N60M2 in standard switching applications.

Engineering Selection Recommendations

AOTF190A60L (Alpha & Omega Semiconductor Inc.)

This substitute provides electrical equivalence with 600V Vdss and 20A continuous drain current rating. The device is RoHS3 compliant and operates across the full -55°C to 150°C temperature range. The TO-220F package is mechanically compatible with standard TO-220 footprints. However, this part carries "Not For New Designs" status, restricting its use to legacy system maintenance and field replacement scenarios only. Long-term availability cannot be assured.

R6022YNXC7G (Rohm Semiconductor)

This substitute meets the 600V Vdss requirement and operates across the required temperature range. The TO-220FM package is mechanically compatible with TO-220 footprints. The continuous drain current rating of 13A is lower than the STF26N60M2 specification of 20A, making this device suitable only for applications where actual current demand does not exceed 13A. RoHS3 compliance status is not specified in available documentation. This part is suitable for applications with reduced current requirements.

TK16A60W5,S4VX (Toshiba Semiconductor and Storage)

This substitute provides 600V Vdss rating with 15.8A continuous drain current and is RoHS3 compliant. The TO-220SIS package is mechanically compatible with standard TO-220 mounting. The continuous drain current rating of 15.8A is lower than the STF26N60M2 specification of 20A, making this device suitable only for applications where actual current demand does not exceed 15.8A. Product status is Active, supporting long-term availability. This part is suitable for applications with reduced current requirements.

Frequently Asked Questions (FAQ)

Q: Can AOTF190A60L be used as a direct replacement for STF26N60M2 in new designs?

A: No. AOTF190A60L carries "Not For New Designs" status and is restricted to legacy system maintenance and field replacement only. For new designs, select TK16A60W5,S4VX or R6022YNXC7G if current requirements permit, or source additional STF26N60M2 inventory.

Q: Why do R6022YNXC7G and TK16A60W5,S4VX have lower current ratings than STF26N60M2?

A: These devices are rated for 13A and 15.8A continuous drain current respectively, compared to 20A for the STF26N60M2. These lower ratings reflect different semiconductor die designs and thermal characteristics. Substitution is valid only when actual circuit current demand does not exceed the substitute device rating.

Q: Are all substitute parts compatible with the same PCB footprint?

A: All substitute parts use TO-220 package variants (TO-220F, TO-220FM, TO-220SIS) and are mechanically compatible with standard TO-220 through-hole footprints. Pin configuration and lead spacing are identical across all variants listed.

Q: What is the significance of the different Rds On values between parts?

A: Rds On (on-state resistance) varies between devices due to different semiconductor technologies and die designs. Lower Rds On values result in reduced power dissipation during conduction. The STF26N60M2 and R6022YNXC7G both specify 165 mOhm maximum, while AOTF190A60L and TK16A60W5,S4VX specify 190 mOhm. This difference affects thermal performance in high-current applications.

Q: Can these substitutes be used interchangeably in high-temperature applications?

A: All listed substitutes support the full -55°C to 150°C operating temperature range. However, actual thermal performance depends on power dissipation, which varies between devices. Verify that the substitute device power dissipation rating exceeds the calculated application power loss at maximum operating temperature.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are RoHS3 compliant and REACH unaffected. ECCN classification is EAR99 for all devices. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.

Q: Is gate voltage compatibility a concern when substituting these parts?

A: Gate voltage ratings differ slightly between substitutes. STF26N60M2 specifies ±25V maximum, while AOTF190A60L specifies ±20V, and both R6022YNXC7G and TK16A60W5,S4VX specify ±30V. Verify that the gate drive circuit voltage does not exceed the substitute device rating. All devices are compatible with standard 10V gate drive signals.
