Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDI404PI is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Driven Configuration: Low-Side (all substitutes must match)
• Number of Drivers: 2 (all substitutes must match)
• Input Type: Inverting (all substitutes must match)
• Package / Case: 8-DIP (0.300", 7.62mm) (all substitutes must match)
• Mounting Type: Through Hole (all substitutes must match)

Functional Compatibility Parameters:

• Gate Type support (IGBT, N-Channel, P-Channel MOSFET capability)
• Voltage - Supply range (must encompass or match the application requirement)
• Current - Peak Output (source and sink capability)
• Operating Temperature range
• Rise / Fall Time characteristics

All identified substitute parts meet the mandatory compatibility criteria. Functional differences exist in supply voltage ranges, output current ratings, and switching speed characteristics, which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

IXDI604PI is the primary substitute for IXDI404PI. Both parts are manufactured by IXYS Integrated Circuits Division and share identical supply voltage range (4.5V ~ 35V) and peak output current ratings (4A source and sink). The IXDI604PI is active in production status with ROHS3 compliance. The primary difference is the operating temperature range: IXDI604PI operates from -40°C to 125°C (TA), compared to IXDI404PI's -55°C to 150°C (TJ). This substitution is suitable for applications where the narrower temperature range is acceptable.

IXDI602PI is an alternative from IXYS Integrated Circuits Division with identical supply voltage range (4.5V ~ 35V) and operating temperature range (-55°C ~ 150°C TJ). However, peak output current is reduced to 2A (source and sink), making this suitable only for applications with lower current drive requirements. IXDI602PI is active in production with ROHS3 compliance.

IR4426PBF is manufactured by International Rectifier and operates within a narrower supply voltage range (6V ~ 20V). Peak output current is 2.3A (source) and 3.3A (sink), with faster switching characteristics (15ns rise, 10ns fall). This part is suitable for applications operating within the 6V to 20V supply range with moderate current requirements.

MIC4423YN and MIC4423ZN are manufactured by Microchip Technology with supply voltage range of 4.5V ~ 18V and peak output current of 3A (source and sink). Both parts feature slower switching characteristics (28ns rise, 32ns fall) compared to IXDI404PI. MIC4423YN operates from -40°C to 150°C (TJ), while MIC4423ZN operates from 0°C to 150°C (TJ). Both are ROHS3 compliant and active in production.

Selection should prioritize active production status parts (IXDI604PI, IXDI602PI, IR4426PBF, MIC4423YN, MIC4423ZN) over the obsolete IXDI404PI. IXDI604PI provides the closest functional match with identical electrical ratings and IXYS manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can IXDI604PI directly replace IXDI404PI in existing designs?

A: IXDI604PI is functionally compatible as a direct replacement from an electrical and mechanical standpoint. Both parts share identical supply voltage range (4.5V ~ 35V), peak output current ratings (4A source and sink), package type (8-DIP), and mounting configuration. The operating temperature range differs: IXDI404PI operates from -55°C to 150°C (TJ), while IXDI604PI operates from -40°C to 125°C (TA). Verify that your application's temperature requirements fall within IXDI604PI's range before substitution.

Q: What is the difference between IXDI602PI and IXDI604PI?

A: Both parts are manufactured by IXYS Integrated Circuits Division with identical supply voltage range (4.5V ~ 35V) and operating temperature range (-55°C ~ 150°C TJ). The primary difference is peak output current: IXDI604PI provides 4A (source and sink), while IXDI602PI provides 2A (source and sink). IXDI604PI also features faster switching characteristics (9ns rise, 8ns fall) compared to IXDI602PI (7.5ns rise, 6.5ns fall). Select IXDI604PI for applications requiring higher gate drive current; select IXDI602PI for lower current applications.

Q: Why does IR4426PBF have a narrower supply voltage range than IXDI404PI?

A: IR4426PBF is specified for operation from 6V to 20V, compared to IXDI404PI's 4.5V to 35V range. This reflects the design specifications of the International Rectifier part. IR4426PBF is suitable only for applications operating within the 6V to 20V supply voltage window. If your application requires operation below 6V or above 20V, IR4426PBF is not a suitable substitute.

Q: Are MIC4423YN and MIC4423ZN interchangeable?

A: MIC4423YN and MIC4423ZN are electrically identical with the same supply voltage range (4.5V ~ 18V), peak output current (3A source and sink), and switching characteristics (28ns rise, 32ns fall). The difference is operating temperature range: MIC4423YN operates from -40°C to 150°C (TJ), while MIC4423ZN operates from 0°C to 150°C (TJ). Select based on your application's minimum operating temperature requirement.

Q: What does "Low-Side" gate driver configuration mean?

A: A low-side gate driver is designed to drive the low-side switch (typically the lower MOSFET or IGBT in a half-bridge or full-bridge configuration). All substitute parts listed are low-side drivers and are compatible with IXDI404PI's low-side configuration. Do not substitute with high-side or high-side/low-side gate drivers, as these have different functional requirements.

Q: Can I use a substitute part with lower peak output current than IXDI404PI?

A: Substitution with lower peak output current (such as IXDI602PI at 2A or MIC4423 series at 3A) is permissible only if your gate drive circuit design does not require the full 4A output current of IXDI404PI. Verify that the substitute part's output current is sufficient to meet your gate charge and switching speed requirements. Insufficient drive current may result in slower switching transitions and increased power dissipation.

Q: Are all substitute parts RoHS compliant?

A: IXDI604PI, IXDI602PI, MIC4423YN, and MIC4423ZN are ROHS3 compliant. IR4426PBF does not specify RoHS status in the provided data. If RoHS compliance is a requirement for your application, select from the IXYS or Microchip parts.
