IXDF502PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDF502PI 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 features independent dual-channel configuration with inverting and non-inverting input types. The product is currently obsolete, making identification of compatible substitute parts essential for system redesign, legacy system maintenance, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IXDF502PI low-side gate driver are qualified based on the following critical parameters:

Primary Compatibility Criteria:

• Driven configuration: Low-side operation
• Channel type: Independent dual channels
• Package type: 8-DIP through-hole form factor
• Input type: Inverting and non-inverting capability
• Gate type compatibility: IGBT and MOSFET support

Secondary Electrical Criteria:

• Supply voltage range (minimum 4.5V lower bound required)
• Peak output current capability (minimum 2A source/sink)
• Logic voltage thresholds (VIL 0.8V, VIH 3V)
• Operating temperature range (minimum -55°C to 150°C preferred)

Two substitute parts meet these criteria with varying degrees of parameter alignment: the IXDF602PI from IXYS and the TC1428CPA from Microchip Technology.

Parameter Comparison

Engineering Selection Recommendations

IXDF602PI (IXYS Integrated Circuits Division) is the primary substitute for IXDF502PI. This part maintains identical electrical specifications including 2A peak output current, 7.5ns/6.5ns rise/fall times, and -55°C to 150°C operating temperature range. The supply voltage range extends to 35V, providing enhanced headroom. The IXDF602PI is currently in active production status with ROHS3 compliance and REACH unaffected certification. Pinout and package compatibility are confirmed at 8-DIP through-hole form factor. This substitute requires no circuit redesign.

TC1428CPA (Microchip Technology) is a secondary substitute suitable for applications with relaxed performance requirements. While maintaining the same 8-DIP package and low-side configuration, this part has reduced peak output current (1.2A versus 2A), slower switching characteristics (35ns/25ns rise/fall times), and a narrower operating temperature range (0°C to 70°C). The supply voltage range is limited to 4.5V–16V. TC1428CPA is ROHS3 compliant and REACH unaffected. This substitute is appropriate only when application current and temperature requirements fall within its specifications.

Frequently Asked Questions (FAQ)

Q: Can IXDF602PI directly replace IXDF502PI without circuit modification?

A: Yes. The IXDF602PI maintains identical pinout, package configuration (8-DIP), and all critical electrical parameters including peak output current (2A), switching times (7.5ns/6.5ns), and operating temperature range (-55°C to 150°C). No circuit redesign is required.

Q: What are the limitations of TC1428CPA as a substitute?

A: TC1428CPA has three significant limitations: reduced peak output current (1.2A versus 2A), slower switching response (35ns/25ns versus 7.5ns/6.5ns), and narrower operating temperature range (0°C to 70°C versus -55°C to 150°C). Applications requiring high-speed switching, high current drive, or extended temperature operation must use IXDF602PI instead.

Q: Are both substitutes available in the same packaging?

A: Yes. Both IXDF602PI and TC1428CPA use 8-DIP (0.300", 7.62mm) through-hole packages, ensuring mechanical compatibility with existing PCB layouts designed for IXDF502PI.

Q: What compliance certifications apply to the substitute parts?

A: Both IXDF602PI and TC1428CPA are ROHS3 compliant and REACH unaffected. IXDF602PI carries active product status, while TC1428CPA also maintains active status. Both meet current regulatory requirements for new designs.

Q: Which substitute is recommended for new designs?

A: IXDF602PI is the recommended substitute for new designs. It provides full electrical and thermal compatibility with the original IXDF502PI specification, active product status ensuring long-term availability, and superior performance characteristics compared to TC1428CPA.
