2 A per contact, tin finish, signal-duty only
The 1-2314915-4: Tin is a cost-effective finish for applications with low mating-cycle counts — typically under 50 cycles — and non-corrosive environments. The solder post length is 0.083" (2.11 mm) — enough for a standard through-hole board thickness but short enough to avoid bottom-side clearance issues.
14 vs 16 positions: when to move up
The closest sibling is 1-2314915-6, which is identical in every dimension and finish except it carries 16 positions instead of 14. If the BOM calls for 16 circuits, the 14-position part won't fit — the extra two positions are physically missing. Gold handles 500+ cycles versus the tin's ~50-cycle limit, at a higher per-unit cost.
