Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IRGP4068DPBF are selected based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Voltage - Collector Emitter Breakdown: 600V (exact match required)
• Current - Collector (Ic) (Max): 96A or higher
• Package / Case: TO-247-3 (mechanical compatibility)
• Mounting Type: Through Hole (board-level compatibility)

Secondary Compatibility Parameters:

• Power - Max: 330W or higher
• Operating Temperature Range: Must include -55°C to 175°C or equivalent
• Gate Charge: Similar range (70-100 nC preferred for switching characteristics)
• Vce(on) characteristics: Comparable conduction losses

The substitute parts listed below meet these criteria within acceptable engineering tolerances. Substitutes are grouped by manufacturer and IGBT technology type (Trench, Trench Field Stop, or PT) to facilitate selection based on application requirements and design constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - Highest Compatibility:

APT54GA60BD30 (Microchip Technology) is the recommended primary substitute. This part matches the IRGP4068DPBF across all critical parameters: 600V voltage rating, 96A collector current, TO-247-3 package, and through-hole mounting. The APT54GA60BD30 is classified as Active product status, ensuring long-term availability and supply chain stability. It carries ROHS3 compliance and maintains the same regulatory certifications (REACH Unaffected, EAR99). The PT IGBT technology provides optimized switching characteristics with lower gate charge (28nC) compared to the original Trench design, resulting in improved switching efficiency.

Secondary Substitutes - Acceptable Alternatives:

IXXH50N60B3D1 (IXYS) provides the highest current rating (120A) and power dissipation (600W) among available substitutes, offering design margin for applications requiring higher transient current handling. This part maintains 600V voltage rating, TO-247-3 package compatibility, and Active product status. The PT IGBT technology and lower gate charge (70nC) support efficient switching operation.

STGW60H65DFB (STMicroelectronics) offers a 650V voltage rating with 80A collector current and Active product status. This part is suitable for applications where slightly elevated voltage margin is beneficial. The Trench Field Stop technology and improved switching energy characteristics (1.09mJ on, 626µJ off) provide enhanced performance in high-frequency switching applications.

IXGH36N60B3 (IXYS) provides 92A collector current with Active product status and GenX3™ series designation. This part is appropriate for applications where current requirements are slightly below 96A. The lower power rating (250W) should be verified against thermal design requirements.

IKW50N60DTPXKSA1 (Infineon) maintains manufacturer continuity as an Infineon product with 600V rating and 80A collector current. However, this part carries Not For New Designs status, limiting its suitability for new applications despite technical compatibility.

NGTB45N60S2WG (onsemi) is not recommended as a primary substitute due to significantly reduced collector current rating (45A), which falls below the original 96A specification and limits application scope.

All recommended substitutes maintain ROHS3 compliance, REACH Unaffected status, and EAR99 classification, ensuring regulatory and export compliance equivalence with the original IRGP4068DPBF.

Frequently Asked Questions (FAQ)

Q1: Why is the IRGP4068DPBF classified as Obsolete, and what does this mean for my application?

A: Obsolete classification indicates that Infineon Technologies has discontinued manufacturing and support for this component. For active applications, substitute parts must be identified to ensure continued system operation and maintenance capability. The substitute parts listed above provide functional equivalence while offering access to active product lines with guaranteed long-term availability.

Q2: Can I use a substitute part with lower collector current rating (e.g., IXGH36N60B3 at 92A instead of 96A)?

A: Substitution with lower current ratings is permissible only if your application's maximum operating current does not exceed the substitute part's rating. The IXGH36N60B3 (92A) operates within 96% of the original specification and is suitable for applications with peak currents at or below 92A. Thermal design verification is required to confirm adequate heat dissipation margin.

Q3: What is the significance of different IGBT types (Trench, Trench Field Stop, PT) among the substitutes?

A: IGBT technology type affects switching characteristics, conduction losses, and gate charge requirements. Trench designs (original IRGP4068DPBF) offer moderate switching speed. Trench Field Stop designs (IKW50N60DTPXKSA1, STGW60H65DFB) provide improved reverse recovery characteristics. PT (Punch-Through) designs (APT54GA60BD30, IXGH36N60B3, IXXH50N60B3D1) offer lower gate charge and faster switching. All types are electrically compatible within the specified voltage and current parameters; selection depends on circuit switching frequency and driver capability.

Q4: Are all substitute parts available in the same TO-247-3 package?

A: Yes. All substitute parts listed are packaged in TO-247-3 (or equivalent TO-247 variants) with through-hole mounting, ensuring mechanical and board-level compatibility with the original IRGP4068DPBF. Supplier device package designations may vary slightly (e.g., TO-247AC, TO-247AD, PG-TO247-3) but represent the same physical form factor.

Q5: Which substitute offers the best long-term availability and supply chain stability?

A: APT54GA60BD30 (Microchip Technology) and STGW60H65DFB (STMicroelectronics) both carry Active product status, indicating ongoing manufacturing and support. These parts are preferred for new designs and long-term applications. IKW50N60DTPXKSA1, while technically compatible, carries "Not For New Designs" status and should be avoided for applications requiring extended product lifecycle support.

Q6: Do I need to modify my circuit design to use a substitute part?

A: No circuit design modifications are required for the recommended substitutes (APT54GA60BD30, IXXH50N60B3D1, STGW60H65DFB, IXGH36N60B3). All parts maintain 600V voltage rating, TO-247-3 package, and standard gate drive interface compatibility. However, differences in gate charge and switching energy may affect driver performance; verification of gate drive current capability is recommended, particularly for high-frequency applications.

Q7: What compliance certifications should I verify when selecting a substitute?

A: All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the original IRGP4068DPBF regulatory profile. EAR99 export classification is consistent across all parts. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for most substitutes, indicating no special storage or handling requirements. Verify these certifications with your procurement documentation to ensure compliance with your application's regulatory requirements.

Q8: Can I use NGTB45N60S2WG as a substitute despite its lower current rating?

A: NGTB45N60S2WG is not recommended as a substitute for the IRGP4068DPBF due to its significantly reduced collector current rating (45A versus 96A). This part is suitable only for applications with maximum operating currents below 45A and represents a substantial design downgrade. Alternative substitutes with higher current ratings should be prioritized.

Q9: How do switching energy differences between substitutes affect my application?

A: Switching energy (on and off) directly impacts power dissipation and thermal design. Lower switching energy reduces heat generation and improves efficiency. APT54GA60BD30 exhibits the lowest total switching energy (534µJ on + 466µJ off = 1000µJ), while IKW50N60DTPXKSA1 shows higher energy (1.53mJ on + 850µJ off = 2.38mJ). For high-frequency switching applications, lower switching energy substitutes (APT54GA60BD30, IXGH36N60B3) are preferred. Thermal analysis should be performed to confirm adequate heat dissipation with your selected substitute.

Q10: What is the operating temperature range consideration when selecting a substitute?

A: The original IRGP4068DPBF operates from -55°C to 175°C (TJ). Most substitutes maintain this range or a subset thereof. APT54GA60BD30 and IXGH36N60B3 operate to 150°C maximum junction temperature, which is acceptable for most industrial applications but may limit performance in extreme high-temperature environments. STGW60H65DFB and IXXH50N60B3D1 maintain the full -55°C to 175°C range, providing maximum thermal margin. Verify your application's operating temperature requirements against the selected substitute's specification.
