FSAM20SH60A Equivalent & Substitute Parts

Part Overview

The FSAM20SH60A is a Smart Power Module (SPM) IGBT driver designed for 3-phase applications with 600V voltage rating and 20A current capacity. This module is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design considerations. The through-hole 32-PowerDIP package configuration requires careful evaluation of substitute options to ensure mechanical and electrical compatibility in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FSAM20SH60A is determined by the following critical parameters:

• Electrical Specifications: Type (IGBT), Configuration (3 Phase), Current Rating (20 A), Voltage Rating (600 V), and Isolation Voltage (2500Vrms) must remain constant
• Mechanical Compatibility: Mounting Type (Through Hole) and Package dimensions must accommodate existing PCB layouts
• Manufacturer Continuity: onsemi as the original manufacturer ensures design consistency and technical support

The FSBB20CH60C qualifies as a substitute based on matching electrical specifications across all critical parameters. However, the package transition from 32-PowerDIP to 27-PowerDIP represents a mechanical change that requires PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

For Existing System Support: The FSBB20CH60C provides electrical equivalence to the FSAM20SH60A with identical current, voltage, and isolation specifications. Both components are classified as discontinued products (Obsolete and Not For New Designs respectively), indicating limited future availability. PCB layout modification is required due to package size reduction from 32-PowerDIP to 27-PowerDIP.

For New Designs: Neither component is recommended for new product development. The FSAM20SH60A is Obsolete, and the FSBB20CH60C is designated Not For New Designs. Current onsemi Motion SPM® product lines should be evaluated for new applications requiring 3-phase IGBT drivers at 600V/20A specifications.

Compliance Considerations: Both parts maintain REACH Unaffected status and equivalent isolation voltage ratings (2500Vrms), supporting use in applications with stringent regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can FSBB20CH60C directly replace FSAM20SH60A without PCB modifications?

A: No. While electrical specifications are identical, the package dimensions differ significantly. The FSBB20CH60C uses a 27-PowerDIP module (1.205", 30.60mm) compared to the 32-PowerDIP module (1.370", 34.80mm) of the FSAM20SH60A. PCB layout changes are required.

Q: Are the isolation voltage ratings equivalent between these parts?

A: Yes. Both components provide 2500Vrms isolation voltage, meeting identical isolation requirements.

Q: What is the difference between Motion SPM® 2 and Motion SPM® 3 series?

A: The FSAM20SH60A belongs to Motion SPM® 2 series, while FSBB20CH60C is part of Motion SPM® 3 series. Both are onsemi product lines for 3-phase IGBT power modules. The series designation reflects design generation differences, but electrical specifications for these specific models remain equivalent.

Q: Why are both parts classified as discontinued?

A: The FSAM20SH60A is Obsolete, indicating end-of-life status. The FSBB20CH60C is marked Not For New Designs, indicating it is available but not recommended for new product development. This reflects onsemi's product lifecycle management for this power module category.

Q: What are the key parameters that must match for substitution?

A: Critical matching parameters are: IGBT type, 3-phase configuration, 20A current rating, 600V voltage rating, 2500Vrms isolation voltage, and through-hole mounting type. Package dimensions and series generation are secondary considerations that may require design modifications.
