Substitute Part Grouping Explanation

Substitute parts for the FS75R12KT4BPSA2 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

IGBT Type: Trench Field Stop
Configuration: Three Phase Inverter
Voltage - Collector Emitter Breakdown (Max): 1200 V
Current - Collector (Ic) (Max): 75 A
Power - Max: 20 mW
Vce(on) (Max) @ Vge, Ic: 2.15 V @ 15 V, 75 A
Current - Collector Cutoff (Max): 1 mA
Input Capacitance (Cies) @ Vce: 4.3 nF @ 25 V
Operating Temperature Range: -40°C ~ 150°C (TJ)
Mounting Type: Chassis Mount
Package / Case: Module
Supplier Device Package: AG-ECONO2B
Series: EconoPACK™ 2
Manufacturer: Infineon Technologies

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations in electrical performance, thermal characteristics, or mechanical form factor are permitted for substitution classification.
