Hello, I developed the board with LPS27HHTWTR. But can purchase only LPS27HHWT. I don't see the difference in the data sheets. What is the difference between the components? are both have the same footprint?

Hi @SPodl.1​ ,

The only existing part number is LPS27HHTW.

The LPS27HHTWTR (i.e. + a final TR) means only that the device has been packed in Tape&Reel, while the LPS27HHWT I'm afraid it doesn't exist (maybe just a typo for LPS22HHTW).

Thank You, Elleon

I've found these two parts in Digikey:

Can You please explain what's the difference between them?

Hi @SPodl.1​ ,

ok now I have understood the point.

There are two different "flavors" of the same pressure sensor:

• LPS27HHW
• LPS27HHTW

The main difference is that in the LPS27HHTW the pressure sensor is equipped with an internal readable temperature sensor whose accuracy is ±1.5 °C. If you do not need this feature, the two devices are equivalent.
