Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXTY1R4N60P TRL is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• FET Type: N-Channel
• Drain to Source Voltage (Vdss): 600V
• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Operating Temperature Range: -55°C to 150°C (TJ)
• Drive Voltage (Max Rds On): 10V
• Vgs (Max): ±30V

Functional Compatibility Parameters:

• Current - Continuous Drain (Id) @ 25°C: Minimum 1.4A (Tc) or equivalent rating
• Rds On (Max) @ Id, Vgs: Must not exceed 9 Ohm @ 700mA, 10V
• Power Dissipation (Max): Minimum 50W (Tc) or equivalent rating

The substitute parts listed below meet or exceed these criteria within the allowed electrical and mechanical specifications for this MOSFET category.

Parameter Comparison

Engineering Selection Recommendations

FQD1N60CTM (Fairchild Semiconductor)

The FQD1N60CTM is an active product with full manufacturing support. It shares identical voltage rating (600V Vdss), package type (TO-252 DPAK), and operating temperature range (-55°C to 150°C). The continuous drain current is rated at 1A (Tc), which is lower than the main part's 1.4A specification. The Rds On specification of 11.5 Ohm @ 500mA, 10V is slightly higher than the main part. Power dissipation is rated at 28W (Tc), which is lower than the main part's 50W rating. This substitute is suitable for applications where the reduced current and power ratings are acceptable within the circuit design margins.

TSM1NB60CP ROG (Taiwan Semiconductor Corporation)

The TSM1NB60CP ROG is an active product with RoHS3 compliance and REACH unaffected status. It matches the main part in voltage rating (600V Vdss), package type (TO-252 DPAK), and operating temperature range (-55°C to 150°C). The continuous drain current is rated at 1A (Tc), lower than the main part's 1.4A. The Rds On specification of 10 Ohm @ 500mA, 10V is comparable to the main part. Power dissipation is rated at 39W (Tc), which is lower than the main part's 50W rating. This substitute provides closer electrical performance alignment and is available in Tape & Reel packaging with MSL 3 (168 Hours) moisture sensitivity rating.

Both substitute parts are active products with established supply chains, addressing the obsolescence status of the main part. Selection between them depends on specific application requirements regarding current capacity, power dissipation headroom, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the FQD1N60CTM or TSM1NB60CP ROG be used as direct replacements for the IXTY1R4N60P TRL?

A: Both parts share the same voltage rating (600V), package type (TO-252 DPAK), and operating temperature range. However, both substitute parts have lower continuous drain current ratings (1A vs. 1.4A) and lower maximum power dissipation (28W or 39W vs. 50W). Direct substitution is possible only if the application circuit operates within the reduced current and power specifications of the substitute parts.

Q: What are the key differences in on-resistance between these parts?

A: The IXTY1R4N60P TRL has an Rds On of 9 Ohm @ 700mA, 10V. The FQD1N60CTM has 11.5 Ohm @ 500mA, 10V, and the TSM1NB60CP ROG has 10 Ohm @ 500mA, 10V. The TSM1NB60CP ROG provides closer on-resistance performance to the main part.

Q: Are the packages physically identical?

A: Yes. All three parts use the TO-252-3 DPAK (2 Leads + Tab) package, also designated SC-63. They are physically interchangeable at the board level.

Q: What is the significance of the different gate charge specifications?

A: The main part has a gate charge of 5.2 nC @ 10V, while both substitutes have slightly higher values (6.2 nC and 6.1 nC respectively). Higher gate charge results in longer switching times and increased driver power requirements. This difference is minor and typically does not affect circuit functionality in most applications.

Q: Why do the substitute parts have lower power dissipation ratings?

A: The FQD1N60CTM and TSM1NB60CP ROG are rated for lower continuous drain currents (1A vs. 1.4A), which directly impacts their maximum power dissipation capability. Applications requiring the full 50W dissipation of the main part may require thermal management evaluation when using these substitutes.

Q: What is the difference between the packaging formats offered?

A: The IXTY1R4N60P TRL is available in standard packaging. The FQD1N60CTM is available in Bulk packaging. The TSM1NB60CP ROG is available in Tape & Reel (TR) format with MSL 3 (168 Hours) moisture sensitivity. Tape & Reel format is standard for automated assembly processes.

Q: Are there compliance or certification differences between these parts?

A: The TSM1NB60CP ROG carries RoHS3 compliance and REACH unaffected status. The FQD1N60CTM and main part specifications do not explicitly list these certifications in the provided data. Compliance requirements should be verified against specific application standards.
