I have a similar query regarding authenticity of a BMP280 part. Our AOI picked up this marking discrepancy on a recent batch of parts purchased and we are unable to find any reference to "Y" as a valid part identifier for the BMP280 or any other Bosch sensor in a similar package. (Refer images below comparing suspect batch vs expected part). Left, "YP" marking, Right, "KZ" marking The part passes our functional test (i.e. basic sanity reading of temperature and pressure). Can you provide any indication of whether the "Y" is valid for a BMP280 and, if not, whether this corresponds to any other Bosch part marking? Thank you in advance for your assistance. John
