FSAM50SM60A Equivalent & Substitute Parts

Part Overview

The FSAM50SM60A is an IGBT power driver module manufactured by onsemi, designed for 3-phase inverter applications. This module integrates a 600V, 50A IGBT configuration in a 32-PowerDIP package with 2500Vrms isolation capability. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system redesign, maintenance, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FSAM50SM60A is determined by the following critical parameters:

• Current Rating: 50 A (exact match required)
• Configuration: 3 Phase Inverter (functional requirement)
• Voltage Isolation: 2500Vrms (isolation specification)
• Type: IGBT (semiconductor technology)
• Mounting Type: Through Hole (PCB integration requirement)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part NFAL5065L4B meets these core substitution criteria. While the voltage rating differs (650V vs. 600V), this represents an uprated specification that maintains backward compatibility for 600V applications. The package footprint differs (30-PowerDIP vs. 32-PowerDIP), requiring PCB layout verification before implementation.

Parameter Comparison

Engineering Selection Recommendations

The NFAL5065L4B is the identified substitute for the obsolete FSAM50SM60A based on functional equivalence in current rating, isolation voltage, and 3-phase inverter configuration. Both parts maintain ROHS3 compliance and are manufactured by onsemi.

The NFAL5065L4B carries active product status, ensuring ongoing availability and support. The 650V rating of the substitute provides margin above the 600V specification of the original part, making it suitable for applications designed around the FSAM50SM60A.

Package footprint differences require verification: the NFAL5065L4B uses a 30-PowerDIP module (1.385", 35.17mm) compared to the 32-PowerDIP module (1.370", 34.80mm) of the original. PCB layout and mechanical clearance must be confirmed before design implementation.

Frequently Asked Questions (FAQ)

Q: Can the NFAL5065L4B directly replace the FSAM50SM60A without PCB modifications?

A: The substitute part has identical current and isolation ratings but differs in package dimensions and pin count (30-pin vs. 32-pin). PCB layout verification is required to confirm mechanical fit and electrical connectivity.

Q: Why is the voltage rating higher on the substitute part?

A: The NFAL5065L4B is rated for 650V, which exceeds the 600V specification of the FSAM50SM60A. This uprated specification is compatible with 600V applications and provides additional voltage margin.

Q: Are both parts RoHS compliant?

A: Yes, both the FSAM50SM60A and NFAL5065L4B are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the significance of the product status difference?

A: The FSAM50SM60A is obsolete, meaning it is no longer manufactured or supported. The NFAL5065L4B carries active status, ensuring continued availability, technical support, and supply chain reliability.

Q: Are the isolation voltage specifications identical?

A: Yes, both parts provide 2500Vrms isolation, meeting the isolation requirements of 3-phase inverter applications.
