Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FSB70450F is determined by strict equivalence across the following critical parameters:

• Configuration: 3 Phase Inverter topology
• Current Rating: 4.8 A
• Voltage Rating: 500 V
• Voltage - Isolation: 1500 Vrms
• Package / Case: 27-PowerLQFN Module
• Mounting Type: Surface Mount
• Type: MOSFET

The FSB70450 qualifies as a direct substitute based on identical electrical specifications and package form factor. Both components share the same base product number (FSB704), series designation (Motion SPM® 7), and regulatory compliance profile. The primary distinction is product status and packaging configuration.

Parameter Comparison
