Part Number: INA220
Other Parts Discussed in Thread: INA228, INA229, INA237, , INA239, INA238


We are using INA220AIDGSR on our PCB. Unfortunately, this part # has extremely long lead times and are tough to get.

What is a suitable replacement that we can use to replace INA220AIDGSR. We would like to have minimal or no PCB changes. Is there a drop in 
replacement that is readily available?

  • Marie,

    Our new INA22x and INA23x families are also found in VSSOP and are pin for pin to INA220, with the exception that pin 3 is now an ALERT pin. This pin was NC on INA220. These devices are precision digital power monitors, and should be an upgrade to the INA220 in most areas. The products in the family for convenience are INA228, INA229, INA237, INA238, and INA239.
