IXDN504PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDN504PI is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT and MOSFET gates in power management applications. This 8-DIP through-hole component operates across a 4.5V to 30V supply range with dual independent channels and non-inverting input configuration. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXDN504PI is determined by the following critical parameters:

• Driven Configuration: Must be low-side
• Channel Type: Must be independent
• Number of Drivers: Must be 2
• Input Type: Must be non-inverting
• Package / Case: Must be 8-DIP (0.300", 7.62mm) through-hole
• Gate Type Compatibility: Must support IGBT and/or N-Channel MOSFET
• Voltage - Supply Range: Must encompass or overlap the 4.5V ~ 30V requirement
• Current - Peak Output: Must meet or exceed 4A source and 4A sink capability
• Operating Temperature Range: Must support -55°C ~ 150°C or equivalent thermal envelope

Three substitute parts meet these criteria: IXDN604PI, IXDN602PI, and IR4427PBF. Each maintains the core functional architecture while offering variations in electrical performance and product status.

Parameter Comparison

Engineering Selection Recommendations

IXDN604PI is the primary substitute for IXDN504PI. Both parts are manufactured by IXYS with identical electrical performance (4A source/sink current, 9ns/8ns rise/fall times) and package configuration. IXDN604PI is currently in active production status with ROHS3 compliance and REACH unaffected certification. The supply voltage range extends to 35V, providing enhanced headroom. Operating temperature range is -40°C to 125°C (TA), which is narrower than the original -55°C to 150°C (TJ) specification; this difference must be evaluated against application requirements.

IXDN602PI serves as an alternative when lower output current is acceptable. This IXYS part maintains the full -55°C to 150°C operating range and extends supply voltage to 35V. Peak output current is reduced to 2A source/sink, and rise/fall times are faster (7.5ns/6.5ns). ROHS3 compliance and REACH unaffected status are confirmed. Selection of this part requires verification that 2A output current is sufficient for the gate drive application.

IR4427PBF is a cross-manufacturer substitute from International Rectifier. This part maintains the 8-DIP package and non-inverting low-side configuration but operates within a narrower 6V to 20V supply range. Peak output current is 2.3A source and 3.3A sink, below the original 4A specification. Rise/fall times are slower at 15ns/10ns. This part is suitable only for applications where the reduced current capability and narrower voltage range do not present constraints.

Frequently Asked Questions (FAQ)

Q: Can IXDN602PI replace IXDN504PI in all applications?

A: IXDN602PI is functionally compatible in package, configuration, and gate type support. However, peak output current is reduced from 4A to 2A. Substitution is valid only if the gate drive circuit requires 2A or less. Verify gate capacitance and switching frequency requirements against the reduced current specification.

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

A: Both are IXYS low-side gate drivers in 8-DIP packages with identical supply voltage range (4.5V ~ 35V) and operating temperature support. IXDN604PI provides 4A peak output current matching the original IXDN504PI, while IXDN602PI provides 2A. IXDN602PI offers faster switching times (7.5ns/6.5ns vs. 9ns/8ns). Select IXDN604PI for direct performance equivalence or IXDN602PI if reduced current and faster switching are acceptable.

Q: Is IR4427PBF suitable as a substitute?

A: IR4427PBF maintains the 8-DIP through-hole package and non-inverting low-side configuration. However, it operates within a 6V to 20V supply range (narrower than IXDN504PI's 4.5V ~ 30V) and provides reduced peak output current (2.3A source, 3.3A sink vs. 4A). This part is suitable only for applications where both the narrower voltage range and reduced current capability are acceptable.

Q: Does operating temperature range affect substitution?

A: IXDN504PI specifies -55°C to 150°C (TJ). IXDN604PI operates -40°C to 125°C (TA), a narrower range. IXDN602PI and IR4427PBF support -55°C to 150°C and -40°C to 150°C respectively. Verify application temperature requirements before selection. If the system requires operation below -40°C or above 125°C, IXDN604PI is not suitable.

Q: Are all substitute parts RoHS and REACH compliant?

A: IXDN604PI and IXDN602PI are confirmed ROHS3 compliant with REACH unaffected status. IR4427PBF compliance status is not specified in the provided data. Verify compliance requirements with your procurement and regulatory teams before final selection.

Q: Can these parts be used interchangeably on the same PCB?

A: All substitute parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pin configuration for low-side gate driver function. Physical interchangeability on the PCB is confirmed. Electrical interchangeability depends on circuit requirements for supply voltage range, output current, and operating temperature.
