| FFF Compatibility | Identical SOT-23-5 package and pinout assignment.Same physical dimensions and package style (SOT-23-5).Matches all key specifications, including 60V max input voltage, 800kHz bandwidth, and -40°C to 125°C temperature range. | Same 5-pin SOT-23 pinout assignment (Pin 1: OUT, Pin 2: GND, Pin 3: VIN+, Pin 4: VIN-, Pin 5: V+).Identical SOT-23-5 package size and mounting footprint.Narrower operating temperature range (-40°C to 85°C vs 125°C) and lower bandwidth (440kHz vs 800kHz). | ||
 AI Summary | INA168NA/250G4 by Texas Instruments: Current Monitor Regulator High-Side SOT-23-5. | This is the direct active replacement for the obsolete INA168NA/250G4. Texas Instruments phased out the 'G4' packaging suffix because standard active part numbers are now fully lead-free and Green. It serves as a perfect, zero-risk drop-in replacement.
| A sibling part within the same product family that shares the exact package and pinout. While it supports the same 60V maximum input voltage, it trades off performance with a lower bandwidth of 440kHz, slightly higher quiescent current (60µA vs 25µA), and a narrower industrial temperature rating.
