IXFR48N60Q3 Equivalent & Substitute Parts

Part Overview

The IXFR48N60Q3 is an N-Channel 600V 32A MOSFET manufactured by IXYS in the HiPerFET™ Q3 Class series. This device is packaged in ISOPLUS247™ (TO-247-3) through-hole configuration and is rated for 500W maximum power dissipation. The part is currently Active in product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary device becomes unavailable, when design flexibility is required across manufacturing sources, or when alternative electrical characteristics within acceptable parameters can optimize cost or performance for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXFR48N60Q3 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Drain to Source Voltage (Vdss): 600V
• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Mounting Type: Through Hole
• Package / Case: TO-247-3 compatible

Acceptable Variation Criteria:

• Current - Continuous Drain (Id): Minimum 22A (substitute must support application current requirements)
• Rds On (Max): Up to 170mOhm (within acceptable on-resistance range)
• Power Dissipation (Max): Minimum 227W (substitute must handle thermal load)
• Operating Temperature Range: -55°C to 150°C (must match or exceed)

The three substitute parts listed (FCH165N60E, FCH170N60, R6024KNZ1C9) meet all mandatory matching criteria and fall within acceptable variation ranges for continuous drain current and on-resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

IXFR48N60Q3 (Primary Part)

• Active product status with full manufacturing support
• Highest continuous drain current rating (32A) among the group
• Lowest on-resistance (154 mOhm) providing superior thermal efficiency
• Highest power dissipation capability (500W)
• Full RoHS3 compliance and REACH unaffected status
• Recommended for new designs requiring maximum performance and reliability

FCH170N60 (Preferred Substitute)

• Active product status with ongoing manufacturing availability
• Meets all mandatory electrical and mechanical parameters
• Suitable for applications where 22A continuous drain current is sufficient
• Comparable on-resistance (170 mOhm) within acceptable range
• Identical operating temperature range and through-hole TO-247-3 packaging
• Recommended as primary substitute when IXFR48N60Q3 availability is constrained

FCH165N60E (Secondary Substitute)

• Not For New Designs status indicates limited future availability
• Meets mandatory electrical and mechanical parameters
• 23A continuous drain current rating acceptable for moderate-current applications
• Comparable on-resistance (165 mOhm) to FCH170N60
• Full RoHS3 compliance maintained
• Suitable for legacy design updates or temporary supply solutions only

R6024KNZ1C9 (Tertiary Substitute)

• Obsolete product status with no manufacturing support
• 24A continuous drain current rating within acceptable range
• Comparable on-resistance (165 mOhm)
• Lower power dissipation (245W) than primary part
• Full RoHS3 compliance and REACH unaffected status
• Not recommended for new designs; use only for legacy system maintenance where no alternatives exist

Frequently Asked Questions (FAQ)

Q: Can FCH170N60 directly replace IXFR48N60Q3 in existing designs?

A: FCH170N60 is electrically and mechanically compatible as a substitute. Both devices share identical 600V Vdss rating, N-Channel configuration, TO-247-3 packaging, and -55°C to 150°C operating temperature range. However, the lower continuous drain current rating (22A versus 32A) and reduced power dissipation (227W versus 500W) must be evaluated against application requirements. Thermal analysis is necessary to confirm adequate heat dissipation in the target circuit.

Q: What is the primary difference between IXFR48N60Q3 and the substitute parts?

A: The IXFR48N60Q3 provides superior current handling (32A) and power dissipation (500W) compared to all substitutes. FCH170N60 and FCH165N60E are rated for 22-23A continuous drain current with 227W power dissipation. R6024KNZ1C9 offers 24A at 245W. These differences reflect design trade-offs between performance capability and cost. Selection depends on whether the application requires the full 32A capability or can operate within lower current ratings.

Q: Are all substitute parts RoHS3 compliant?

A: IXFR48N60Q3, FCH165N60E, and R6024KNZ1C9 are explicitly RoHS3 compliant. FCH170N60 RoHS3 compliance status is not specified in the provided data. Compliance verification with the component supplier is required before use in applications with RoHS3 mandates.

Q: Why is R6024KNZ1C9 listed as obsolete?

A: R6024KNZ1C9 carries an Obsolete product status, indicating Rohm Semiconductor has discontinued manufacturing and support. This part should not be selected for new designs. Use is limited to legacy system maintenance where existing inventory exists and no active alternatives are available.

Q: Can I use FCH165N60E for new product development?

A: FCH165N60E carries a Not For New Designs status from onsemi, indicating the manufacturer does not recommend this part for new applications. While electrically functional, future availability cannot be guaranteed. FCH170N60 is the preferred onsemi alternative for new designs, as it maintains Active product status.

Q: What is the significance of on-resistance (Rds On) differences between parts?

A: On-resistance directly affects power dissipation and thermal performance. IXFR48N60Q3 has 154 mOhm, while substitutes range from 165-170 mOhm. Higher on-resistance generates more heat at the same current level. In high-current applications, this difference becomes significant. Thermal modeling is required to confirm that substitute parts with higher on-resistance remain within acceptable junction temperature limits.

Q: Are all parts available in the same packaging format?

A: All parts use TO-247-3 through-hole packaging, ensuring mechanical and thermal interface compatibility. IXFR48N60Q3 is supplied in Tube packaging, FCH170N60 in Bulk, FCH165N60E in Tube, and R6024KNZ1C9 in Tube. Packaging format does not affect electrical performance or board-level compatibility.
