What This 2-Pin Shunt Does on the Board
The 65474-002 is a closed-top jumper from the Mini-Jump™ series — a one-piece female socket that bridges two adjacent header pins. Tin is fine for occasional reconfiguration in a dry, temperature-controlled environment; if the jumper sees repeated mating cycles or lives near a corrosive atmosphere, the gold-plated variants (65474-001 or 65474-010LF) are a better call.
Tin vs. Gold — Which Mini-Jump Fits Your Duty Cycle
The 65474-002 uses tin contacts, while the 65474-001 and 65474-010LF carry gold or GXT™ plating at 40.0µin and 30.0µin respectively. Gold buys you 500+ mating cycles and corrosion resistance; tin is fine for a jumper that gets set once and stays. If your BOM calls for RoHS compliance, note that 65474-002 is RoHS non-compliant — the -LF suffix variants (65474-002LF, 65474-010LF) are the RoHS-compliant equivalents with the same tin or gold finish.
