<p>I ran into the same thing, four.above.five.  I poured through the datasheets and couldn't find the difference between the part number in the sheet and the part numbers your ordered.  I'm 99.99% sure these part numbers are just fine.  I build a lot of devices and manufacturers have a tendency to discontinue part numbers and replace them with new numbers, forcing me to look for equivalent parts.  That might be the case here.
