Cross-Reference to Peer 1-1871673-2
The closest functional peer is 1-1871673-2, a 4-position, dual-row, shrouded header on a wider 2.50 mm pitch with a detent lock. That part adds board locks and a higher voltage rating (250 VAC/DC) but uses tin-plated mating contacts — a downgrade for high-cycle applications. The 2842112-3 covers a different BOM position: single-row, tighter pitch, gold mating interface, no locking feature.
