Board-Layout Fit: Pitch, Count, and Footprint
The 54201-G0803ALF: Single-row, 3 positions loaded — the board keeps a narrow 7.62mm-wide keep-out zone plus the solder pad length. The unshrouded design leaves the mating interface exposed, which keeps the z-height low.
Contact Finish and Mating Duty
In a test-bench or programming fixture where the connector sees hundreds of insertions, that plating holds contact resistance stable well past 500 cycles. The solder post gets a 100.0µin tin finish — adequate for reflow wetting; the gold-on-tin interface at the board joint is avoided because the post is tin-only.
Peer Comparison: Position Count and Plating Options
For a production run with fewer than 100 mating cycles, the thinner gold saves cost; for a field-service connector, the 30µin version is the safer call.
