	18	+Each outline gives body length and width, height, standoff, terminal length and width, and the thermal pad's size. The model uses the middle of each range; DNX0008A gives its height as 0.5 maximum only. The terminal thickness is the outline's reference value.

19	20	The thermal pad is the TI outline's. A footprint whose name gives a different pad size, such as `DFN-8-1EP_4x4mm_P0.8mm_EP2.5x3.6mm` against DRM0008A's 2.45 x 3.38 mm, isn't this part even when the body and pitch match.
	21	+
	22	+A footprint name's pad counts as the outline's when each side is within 0.05 mm, since pad labels are rounded. Matched within that: `DFN-8-1EP_3x3mm_P0.5mm_EP1.66x2.38mm` to DNX0008A (1.65 x 2.38 mm).
