Hello randy.parlmer, welcome to the DigiKey TechForum.  
You should post a picture of the top marking. If the markings are seperated by a space or a different line, can make all the difference. Some of the marking may be a Date/lot code reference, or factory location. Also, if there is any manufacture symbol, along with the markings.
