Sourcing and compliance at a glance
The 54201-S0803LF: Supplied in bulk.
Peer comparison: 15 vs 30 µinch gold
The 54201-G0803LF shares the same 3-position, 2.54 mm pitch, SMT, and unshrouded form factor, but carries 30.0 µinch (0.76 µm) gold on the mating surface — double the thickness of the -S0803LF. For a harness that sees quarterly field-service reconnects, the thicker gold extends the reliable mating-cycle window; for a one-time board-to-board jumper inside a sealed enclosure, the 15 µinch finish is sufficient.
