    Hi Cheongmei,

    We are transitioning OPA2227 op amp's molding compound from MSL3 to MSL2, which it will benefit from users' perspective and longer open air storage time. That is the reasons that you are seeing both MSL3 and MSL2 ratings in our inventory and material specification. MSL2 is the latest and revised moisture sensitivity rating for the future of the part. 

    Once the remaining MSL3 inventory is depleted, MSL2 will be the standard and material content information will be updated then. 

    You have to check the shipping box labeling in the MSL ratings at the moment. You are still able to get MSL3 OPA2227U part from TI E-store. 

    The following application note about Power Module MSL Ratings and Reflow Ratings may be interest to you.

    If you have other questions, please let me know. 

    Best,

    Raymond
