Part Number: TCA9555

Asking on behalf of customer.

The TCA9555RTWR is out of stock; can the TCA9555RGER be used as a drop in replacement without modifying the PCB?

It appears the PCB patterns are very very similar.

Thanks!

Hey Steve,

There shouldn't be any issues with the two packages being used interchangeably. The only significant difference between the two is the height and the thermal information between these two packages.
