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​ ,

    ok now I have understood the point.

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

    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.

    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:
