The 5-103635-1: It is RoHS compliant and ships in tube packaging.
The 1394090-1 is a 6-position right-angle header in the same AMPMODU MTE family but uses a 0.112" (2.85mm) pitch and tin mating finish — wider pitch and lower cycle life. The 1376366-8 is an 8-position header with 0.087" (2.20mm) pitch and 5 A rating, but it lacks the 4-wall shroud and keying slot of the 5-103635-1. For a 2-position, 0.100" pitch, gold-plated, shrouded header, the 5-103635-1 is the direct BOM match — no alternate drops in without a board layout change.
