Engineering Selection Recommendations

CSD18535KCS (Texas Instruments NexFET™)

The CSD18535KCS is the primary substitute for the IRL60B216. This device maintains the 60V voltage rating and exceeds the current specification with 200A continuous drain current. The Rds On value of 2.0 mOhm at 100A, 10V is marginally higher than the IRL60B216 (1.9 mOhm), representing a 5% increase in on-state resistance. The CSD18535KCS features significantly lower gate charge (81 nC versus 258 nC) and reduced input capacitance (6620 pF versus 15570 pF), resulting in faster switching characteristics and reduced gate drive requirements. Power dissipation is rated at 300W, which is lower than the IRL60B216 (375W). The device is in active production status with ROHS3 compliance and REACH unaffected designation. TO-220-3 packaging is mechanically compatible with TO-220AB footprints.

STP220N6F7 (STMicroelectronics STripFET™ F7)

The STP220N6F7 is a secondary substitute option suitable for applications where the 120A continuous drain current specification is sufficient. This device maintains the 60V voltage rating and TO-220 packaging. The Rds On value of 2.0 mOhm is measured at 60A, 10V, which differs from the reference measurement point. Gate threshold voltage is specified at 4.0V, which is higher than the IRL60B216 (2.4V), indicating different gate drive characteristics. Gate charge and input capacitance are comparable to the CSD18535KCS. Power dissipation is rated at 237W. The device is in active production status with ROHS3 compliance and REACH unaffected designation. This substitute is appropriate for lower-current applications or where thermal management is less demanding.

Selection Basis:

Both substitute parts satisfy the mandatory electrical and mechanical compatibility criteria: 60V Vdss, N-Channel MOSFET technology, through-hole mounting, -55°C to 175°C operating temperature range, ROHS3 compliance, and REACH unaffected status. The CSD18535KCS is recommended as the primary substitute due to current rating alignment and active product status. The STP220N6F7 is suitable for current-limited applications. Both devices are in active production, ensuring long-term availability compared to the obsolete IRL60B216.

Frequently Asked Questions (FAQ)

Q: Can the CSD18535KCS directly replace the IRL60B216 in existing designs?

A: The CSD18535KCS is electrically compatible with the IRL60B216 across the primary parameters: 60V Vdss, N-Channel MOSFET, through-hole TO-220-3 packaging, and -55°C to 175°C operating temperature. The 200A current rating exceeds the 195A requirement. The Rds On increase of 5% (1.9 mOhm to 2.0 mOhm) is within typical design margins. Gate charge reduction improves switching performance. Mechanical compatibility with TO-220AB footprints is confirmed. Thermal design review is recommended due to the 75W reduction in power dissipation rating.

Q: What are the key differences between CSD18535KCS and STP220N6F7?

A: The CSD18535KCS provides 200A continuous drain current, matching the IRL60B216 current class. The STP220N6F7 provides 120A, suitable for lower-current applications. Gate threshold voltage differs: CSD18535KCS at 2.4V matches the IRL60B216, while STP220N6F7 is specified at 4.0V, requiring different gate drive voltage levels. Gate charge is lower in both substitutes compared to the IRL60B216, improving switching speed. Power dissipation ratings are 300W (CSD18535KCS) and 237W (STP220N6F7) versus 375W (IRL60B216).

Q: Are the TO-220-3 and TO-220AB packages mechanically interchangeable?

A: TO-220-3 and TO-220AB are mechanically compatible for through-hole PCB mounting. Both use three leads with identical pin spacing and hole diameter specifications. The primary difference is in the mounting tab design and thermal interface characteristics. PCB layout modifications are not required for package substitution.

Q: What compliance certifications apply to the substitute parts?

A: Both CSD18535KCS and STP220N6F7 are ROHS3 compliant and REACH unaffected. These certifications match the IRL60B216 compliance status, ensuring regulatory compatibility in applications subject to RoHS and REACH requirements.

Q: How does the gate charge difference affect circuit design?

A: The IRL60B216 specifies 258 nC gate charge at 4.5V. The CSD18535KCS specifies 81 nC at 10V, and STP220N6F7 specifies 100 nC at 10V. Lower gate charge reduces the energy required to switch the device and decreases gate drive circuit stress. Gate driver selection should be reviewed to confirm adequate current sourcing capability, though the lower charge requirement typically reduces design constraints.

Q: What is the impact of reduced input capacitance on circuit performance?

A: The IRL60B216 specifies 15570 pF input capacitance at 25V. The CSD18535KCS specifies 6620 pF at 30V, and STP220N6F7 specifies 6400 pF at 25V. Reduced input capacitance decreases the RC time constant in gate drive circuits, enabling faster switching transitions and reducing switching losses. This improvement is particularly beneficial in high-frequency switching applications.

Q: Is the 75W reduction in power dissipation rating a concern?

A: The IRL60B216 is rated for 375W power dissipation, while the CSD18535KCS is rated for 300W. This difference reflects different thermal measurement conditions and device design. Actual power dissipation in the application depends on Rds On, current, and duty cycle. The 5% increase in Rds On (1.9 to 2.0 mOhm) results in proportionally higher conduction losses. Thermal analysis of the specific application is required to confirm adequate heat dissipation with the substitute device.

Q: Why is the IRL60B216 classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, technology advancement, and production economics. The IRL60B216 has been superseded by newer MOSFET designs with improved performance characteristics, such as lower gate charge and reduced input capacitance. The substitute parts CSD18535KCS and STP220N6F7 represent current-generation alternatives with enhanced switching efficiency.

Q: Can both substitute parts be used interchangeably in the same application?

A: The CSD18535KCS and STP220N6F7 are not interchangeable due to different current ratings (200A versus 120A) and gate threshold voltages (2.4V versus 4.0V). Selection depends on the application's current requirements and gate drive voltage levels. The CSD18535KCS is recommended for applications requiring 195A+ current handling. The STP220N6F7 is suitable for applications with lower current demands.
