Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXDN402PI is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Driven Configuration: Low-Side
• Channel Type: Independent dual-channel
• Input Type: Non-Inverting
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Gate Type: Support for IGBT and/or N-Channel MOSFET

Electrical Parameter Ranges for Substitution:

• Voltage - Supply: Must encompass or overlap with 4.5V ~ 35V operating range
• Logic Voltage - VIL, VIH: Must be compatible with 0.8V, 3V thresholds
• Current - Peak Output: Must meet or exceed 2A source and 2A sink requirements
• Operating Temperature: Must support -55°C ~ 150°C range or equivalent industrial specification

All substitute parts listed below meet these mandatory criteria and are classified as active products, ensuring long-term availability and design support.

Parameter Comparison

Engineering Selection Recommendations

IXDN602PI is the primary recommended substitute for IXDN402PI replacement. This part maintains identical electrical specifications including supply voltage range (4.5V ~ 35V), logic thresholds (0.8V, 3V), and output current ratings (2A source/sink). The IXDN602PI is manufactured by IXYS Integrated Circuits Division and carries active product status with ROHS3 compliance certification. Rise and fall times are marginally improved (7.5ns/6.5ns versus 8ns/8ns), and the part supports the same gate types including IGBT and MOSFET configurations. Inventory availability is substantial at 30,050 units.

IXDN604PI serves as an alternative for applications requiring higher output current capability. This part provides 4A source and sink current, double the IXDN402PI specification, while maintaining the same supply voltage range and logic thresholds. The IXDN604PI is ROHS3 compliant and active. Operating temperature range is -40°C to 125°C (TA), which is narrower than the IXDN402PI specification. This part is suitable for designs with higher gate drive current demands.

IR4427PBF is available as a substitute when supply voltage requirements are limited to 6V ~ 20V. This International Rectifier part provides 2.3A source and 3.3A sink current, exceeding IXDN402PI specifications. Logic thresholds are 0.8V and 2.7V, which are compatible with standard logic levels. Operating temperature range extends to -40°C ~ 150°C. This part is suitable for lower voltage applications within the specified range.

MIC4427YN is available as a substitute for applications with supply voltage limited to 4.5V ~ 18V. This Microchip Technology part provides 1.5A source and sink current, which is below the IXDN402PI specification. Logic thresholds are 0.8V and 2.4V. Rise and fall times are slower at 20ns and 29ns respectively. This part is ROHS3 compliant and active. Selection of this part requires verification that lower output current and slower switching times are acceptable for the target application.

Frequently Asked Questions (FAQ)

Q: Can IXDN602PI directly replace IXDN402PI without circuit modifications?

A: Yes. The IXDN602PI maintains identical electrical specifications for supply voltage (4.5V ~ 35V), logic thresholds (0.8V, 3V), output current (2A/2A), and package format (8-DIP through-hole). Pin-to-pin compatibility is maintained. No circuit modifications are required.

Q: What is the key difference between IXDN602PI and IXDN604PI?

A: The primary difference is output current capability. IXDN602PI provides 2A source and sink current, matching the IXDN402PI specification. IXDN604PI provides 4A source and sink current, suitable for applications requiring higher gate drive current. Both maintain identical supply voltage range and logic thresholds. Operating temperature range differs: IXDN602PI supports -55°C ~ 150°C (TJ), while IXDN604PI supports -40°C ~ 125°C (TA).

Q: Why is MIC4427YN listed as a substitute if it has lower output current?

A: MIC4427YN is listed as a substitute because it meets the mandatory compatibility criteria: low-side configuration, independent dual-channel, non-inverting input, 8-DIP package, and through-hole mounting. However, the 1.5A output current specification is below the IXDN402PI requirement of 2A. Selection of this part requires application-specific verification that lower output current is acceptable.

Q: Is the IR4427PBF suitable for all IXDN402PI applications?

A: IR4427PBF is suitable only for applications where the supply voltage requirement is within the 6V ~ 20V range. The IXDN402PI supports 4.5V ~ 35V, which is broader. If the application requires operation below 6V or above 20V, IR4427PBF is not suitable. For applications within the 6V ~ 20V range, IR4427PBF provides compatible functionality with higher output current capability.

Q: Are all substitute parts RoHS compliant?

A: IXDN602PI, IXDN604PI, and MIC4427YN are ROHS3 compliant. IR4427PBF RoHS status is not specified in the provided data. For applications requiring RoHS compliance certification, IXYS or Microchip parts are recommended.

Q: What is the impact of different rise and fall times on circuit performance?

A: Rise and fall times affect gate switching speed and electromagnetic emissions. IXDN602PI provides faster switching (7.5ns/6.5ns) compared to IXDN402PI (8ns/8ns). IXDN604PI provides comparable switching speed (9ns/8ns). IR4427PBF and MIC4427YN have slower switching times (15ns/10ns and 20ns/29ns respectively). For high-frequency switching applications, faster rise and fall times reduce switching losses and EMI. Application-specific circuit analysis is required to determine acceptable switching speed limits.

Q: Can substitute parts be used interchangeably in existing PCB designs?

A: Yes, all substitute parts use the same 8-DIP (0.300", 7.62mm) through-hole package format. PCB footprints and pin assignments are compatible. Direct component substitution on existing PCBs is possible without layout modifications. Verify that the selected substitute part's electrical specifications meet application requirements before implementation.
