What the 3.96mm Pitch and 2 Positions Mean for Your Board
The 280615-1: At this pitch, the trace routing between pins is more forgiving than a 2.54mm header, but the mating receptacle must match this exact pitch—no mixing with 0.100" headers. Two positions on a single row means this is a basic power pair or a single signal pair.
Detent Lock and Shrouded Walls for Vibration Resistance
In a 2-position connector, this is the primary mechanical lock—without it, cable pull could unseat the header from its receptacle.
Tin Plating: When It Works and When It Doesn't
Both the mating contact and the solder post are tin-plated. For applications requiring frequent disconnect—say, quarterly field service—tin frets and oxidises, increasing contact resistance over time. Gold plating would be the upgrade for high-cycle duty, but this part stays with tin.
Flame-Rated Housing for Enclosed Equipment
This is a standard requirement for connectors inside equipment enclosures that must pass UL 746C or IEC 60950-1 flame tests.
