The 1-2314814-0: The tin-plated solder tails (118.1 µinch) keep the board joint reliable through wave solder. Phosphor bronze contact material provides good spring retention; the square contact shape mates with standard 0.64 mm square pin headers.
ROHS3 Compliant — no restricted substances in the plating or polymer.
The 1-2823056-2 is a 12-position, 2.54 mm pitch receptacle with tin-plated contacts (no gold) — that wider pitch changes the board footprint and the tin finish limits mating cycles. If your BOM calls for 10 positions at 2.00 mm with gold, this is the match.
