Plating, Compliance, and Lifecycle
This plating grade supports moderate mating cycle duty — typically 50–100 cycles — but is RoHS non-compliant per the current directive.
Comparing to a Sibling: 1394090-1
The closest functional alternative in the same series is 1394090-1: a 6-position, right-angle, shrouded header with a 0.112" (2.85mm) pitch and tin plating. The 103639-2 has a tighter 0.100" pitch and fewer positions — 3 vs 6 — so the board footprint and circuit count differ. The 1394090-1 uses tin-only plating (39.4µin) versus the 103639-2's tin-lead, which may affect RoHS compliance and mating cycle life.
