PS12033 Equivalent & Substitute Parts

Part Overview

The PS12033 is an Intellimod™ series Power Driver Module featuring integrated gate driver and protection circuits for three-phase IGBT applications. This module operates at 1.2 kV with a rated current of 5 A and is housed in a 28-PowerDIP package measuring 2.717" (69.00mm). The PS12033 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

Substitution of the PS12033 is determined by the following critical electrical and mechanical parameters:

• Voltage Rating: 1.2 kV (mandatory match)
• Current Rating: 5 A (mandatory match)
• Configuration: 3 Phase (mandatory match)
• Isolation Voltage: 2500VDC (mandatory match)
• Type: IGBT Power Driver Module (mandatory match)
• Mounting Type: Through Hole (mandatory match)

The PS22A72 qualifies as a substitute based on matching all mandatory electrical parameters. However, the package form factor differs: the PS22A72 uses a 42-PowerDip Module (1.404", 35.67mm) compared to the 28-PowerDIP Module of the PS12033. This package difference requires PCB layout modification and mechanical re-qualification for any substitution application.

Parameter Comparison

Engineering Selection Recommendations

The PS22A72 is electrically equivalent to the PS12033 across all critical parameters: voltage rating, current capacity, isolation voltage, and three-phase IGBT configuration. Both modules feature identical electrical specifications and unlimited moisture sensitivity rating.

The PS22A72 offers two significant advantages: it maintains active product status with ongoing manufacturer support, and it is RoHS compliant, meeting modern environmental and regulatory requirements. The PS12033, being obsolete and RoHS non-compliant, presents long-term supply and regulatory compliance risks.

The primary consideration for substitution is the package form factor change from 28-PowerDIP to 42-PowerDip. This dimensional difference necessitates PCB layout modification and mechanical re-qualification of the assembly.

Frequently Asked Questions (FAQ)

Q: Are the PS12033 and PS22A72 electrically interchangeable?

A: Yes. Both modules share identical electrical specifications: 1.2 kV voltage rating, 5 A current capacity, 2500VDC isolation voltage, and three-phase IGBT configuration. Electrical functionality is equivalent.

Q: What is the primary difference between these modules?

A: The package form factor differs. The PS12033 uses a 28-PowerDIP Module (2.717", 69.00mm), while the PS22A72 uses a 42-PowerDip Module (1.404", 35.67mm). This requires PCB layout modification for substitution.

Q: Can I use PS22A72 as a direct drop-in replacement?

A: No. The different package dimensions require PCB redesign. The pinout and electrical interface may differ, necessitating full mechanical and electrical re-qualification.

Q: Why is the PS12033 listed as obsolete?

A: The PS12033 is no longer in active production. The PS22A72 represents the current-generation equivalent from Powerex Inc.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is mandatory for products sold in regulated markets. The PS22A72's RoHS compliance ensures regulatory acceptance; the PS12033's non-compliance may restrict use in new designs or regulated applications.

Q: Are both modules rated for the same isolation voltage?

A: Yes. Both modules provide 2500VDC isolation voltage, meeting identical safety and performance requirements.
