PS12032 Equivalent & Substitute Parts

Part Overview

The PS12032 is an Intellimod™ series Power Driver Module featuring integrated gate driver and protection circuits for three-phase IGBT applications. This module operates at 1200V with a 5A current rating and is housed in a 28-PowerDIP package measuring 2.717" (69.00mm). The PS12032 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The PS22A72 qualifies as a functional substitute for the PS12032 based on the following critical electrical parameters:

• Voltage Rating: Both modules operate at 1.2 kV
• Current Rating: Both modules are rated for 5 A
• Configuration: Both are three-phase IGBT driver modules
• Isolation Voltage: Both provide 2500VDC isolation
• Mounting Type: Both use through-hole mounting technology
• Manufacturer: Both are manufactured by Powerex Inc.

The primary distinction between these modules is the package form factor. The PS22A72 uses a 42-PowerDip Module (1.404", 35.67mm) compared to the 28-PowerDIP Module (2.717", 69.00mm) of the PS12032. This package difference requires PCB layout modification but does not affect electrical compatibility when pin assignments are properly mapped.

Parameter Comparison

Engineering Selection Recommendations

The PS22A72 is the designated substitute for the obsolete PS12032. Selection of the PS22A72 is supported by:

• Product Status: The PS22A72 maintains active production status, ensuring long-term availability and supply chain continuity
• Electrical Equivalence: Identical voltage, current, isolation, and configuration specifications enable direct functional replacement
• Compliance: The PS22A72 achieves RoHS compliance, meeting modern regulatory requirements that the PS12032 does not satisfy
• Packaging: The 42-PowerDip package represents a more compact form factor, reducing board space requirements

Implementation of the PS22A72 requires PCB layout revision to accommodate the different package dimensions. Pin mapping verification is necessary prior to assembly.

Frequently Asked Questions (FAQ)

Q: Can the PS22A72 directly replace the PS12032 without PCB modification?

A: The PS22A72 provides electrical equivalence but requires PCB layout changes due to different package dimensions. The 42-PowerDip (1.404", 35.67mm) footprint differs from the 28-PowerDIP (2.717", 69.00mm) footprint. Pin assignment verification is mandatory.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching voltage rating (1.2 kV), current rating (5 A), configuration (3 Phase), isolation voltage (2500VDC), and mounting type (Through Hole). The PS22A72 meets all these criteria.

Q: Why is the PS12032 classified as obsolete?

A: The PS12032 is no longer in active production. The PS22A72 represents the current-generation equivalent from Powerex Inc.

Q: Does the PS22A72 offer any advantages over the PS12032?

A: The PS22A72 is RoHS compliant and maintains active production status. The compact 42-PowerDip package reduces board space compared to the 28-PowerDIP package.

Q: Are there any compatibility concerns when switching from PS12032 to PS22A72?

A: Electrical compatibility is confirmed. Physical compatibility requires PCB redesign to accommodate the different package footprint. Datasheet pin configuration must be cross-referenced during design transition.
