PS12038 Equivalent & Substitute Parts

Part Overview

The PS12038 is an Intellimod™ series IGBT power driver module designed for three-phase applications at 1200V and 25A ratings. This component is packaged in a 24-PowerDIP module format with through-hole mounting. The PS12038 is currently 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 PS22A76 qualifies as a substitute for the PS12038 based on the following matching electrical and mechanical parameters:

• Identical voltage rating: 1.2 kV
• Identical current rating: 25 A
• Identical isolation voltage: 2500VDC
• Identical configuration: 3 Phase IGBT
• Identical mounting type: Through Hole
• Identical moisture sensitivity level: 1 (Unlimited)
• Same manufacturer: Powerex Inc.

The primary difference is the package format: PS12038 uses 24-PowerDIP Module (3.032", 77.00mm), while PS22A76 uses 42-PowerDip Module (1.404", 35.67mm). This package change requires PCB layout modification but does not affect electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PS22A76 is the direct electrical equivalent to the PS12038. Selection between these parts depends on specific application constraints:

PS22A76 is preferred when:

• New designs or redesigns are being implemented
• RoHS compliance is required
• Active product support and availability are priorities
• PCB layout modifications are feasible

PS12038 may be retained when:

• Existing PCB layouts cannot be modified
• Legacy system maintenance requires exact form-factor compatibility
• Inventory of PS12038 units remains available

Both parts share identical electrical specifications, isolation voltage, and current handling capacity. The transition from PS12038 to PS22A76 requires only PCB footprint adjustment; no circuit redesign is necessary.

Frequently Asked Questions (FAQ)

Q: Can PS22A76 directly replace PS12038 without circuit modifications?

A: Yes. The PS22A76 is electrically identical to the PS12038 across all functional parameters: voltage rating, current rating, isolation voltage, and three-phase IGBT configuration. Only the PCB footprint requires modification due to the different package format.

Q: What is the primary difference between PS12038 and PS22A76?

A: The package format differs. PS12038 uses a 24-PowerDIP Module measuring 3.032" (77.00mm), while PS22A76 uses a 42-PowerDip Module measuring 1.404" (35.67mm). Both are through-hole mounted packages.

Q: Is PS22A76 RoHS compliant?

A: Yes. PS22A76 is RoHS compliant, whereas PS12038 is RoHS non-compliant. This is a significant advantage for applications subject to RoHS regulations.

Q: What is the product status of each part?

A: PS12038 is classified as obsolete. PS22A76 is active and currently in production. For new designs, PS22A76 is the recommended choice due to its active status and ongoing manufacturer support.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are rated for 1.2 kV, 25 A, three-phase IGBT operation with 2500VDC isolation voltage. Electrical performance is equivalent.

Q: What inventory status should be considered?

A: PS12038 has 10,100 pieces in stock (obsolete inventory). PS22A76 has 1,210 pieces in stock (active production). For long-term availability, PS22A76 is the more reliable choice.
