INA231: Solder mask difference between the INA231AIYFFT & INA231BIYFDT

Roy Hsu

Part Number: INA231

Hi Team,

My customer is designing with the INA231AIYFFT but they are also co-designing the INA231BIYFDT as a 2nd-source option in case they face shortage in the A part after production.

We wanted to know if these devices can share the same PCB layout as we found a slight difference in solder mask.

INA231AIYFFT:

INA231BIYFDT :

Would the highlighted differences in the two pictures above be an issue if we're using the INA231AIYFFT pattern for both devices on PCB?

Thanks!

Roy
