The section 1.2.4 of the SMD datasheet (5962-00517 Rev. G) mentions as descriptive designator GDFP1-F14 or CDFP2-F14 for the outline letter "D". According to MIL-STD-1835D (4 June 2004), neither of the two designator corresponds to the package in the mechanical drawing f_14.pdf downloadable from this page.
Could you please confirm that the package used for this device (we are buying OP484AM/QMLL, DSCC=5962L0051702VDA) is the one reported in the file f_14.pdf?
