3.00 mm Pitch, 3-Position Single-Row Header — Why That Matters
The 2-1445097-3: This is a 3-position, single-row header on 3.00 mm pitch — the footprint is compact enough for tight board layouts but the pitch keeps routing lanes between pads wide enough for 20-24 AWG wire traces without necking down.
Gold Mating Finish and Locking Ramp — Field Service and Vibration
Current Rating — It Depends on the Wire, Not the Contact
For a given application, the ampacity follows the wire, not the header pin.
RoHS3 compliant per the manufacturer — no restricted substances above threshold levels.
The 1-1871673-2 uses tin mating finish vs the gold on 2-1445097-3 — gold buys higher mating cycle life, tin is adequate for low-cycle connections. If your application calls for frequent disconnect, the gold part is the correct choice.
