Board Fit and Signal Duty
The 5-104363-1: Two positions, single row, all loaded — this is a minimal signal interconnect for a single-ended pair or a low-power sensor line.
Peer Comparison: 1394090-1
The closest functional sibling is 1394090-1: same AMPMODU MTE family, shrouded 4-wall, latch holder, but 6 positions, 0.112" (2.85mm) pitch, and tin-on-tin contacts throughout — no gold on the mating face. If the BOM calls for 2 positions at 2.54mm pitch with gold mating, 5-104363-1 is the match.
