Hi Gloria,

If there is vinyl on the pins and you bought from the TI store I would pursue a return https://www.ti.com/support-quality/additional-information/customer-returns.html as while the device itself could be functional the vinyl on the pins could increase current density on the exposed metal increasing the contact resistance - so it could cause a degradation in performance -and cleaning the pins could induce mechanical damage depending on the strength needed to remove the vinyl. Due to those reasons I would purse the link above as this does seem to be either a packaging issue or a mechanical compliance issue so it should be a straight forward process.

Best,
