Board footprint and circuit count
The 5-535541-4: The single row keeps the board real estate narrow, useful for edge-connector or inline harness layouts where width is tight.
The 2 A per contact rating is a signal-level current; the temperature rise at this load stays well within the UL94 V-0 polyester housing limit.
Peer comparison: 1376775-2
The closest functional alternative is 1376775-2, a 5-position single-row receptacle from the same series. Both use 0.100" pitch, gold mating contacts, and through-hole solder termination. The key difference: 1376775-2 carries a 3 A rating vs 2 A, and its gold plating is only 8 µinch — adequate for moderate cycling but not the 500+ cycle life of the 30 µinch finish on 5-535541-4.
