Board Fit and Footprint Decisions
How This Header Compares to Siblings
The closest functional alternative in the AMPMODU family is 1-1871673-2 — a 4-position, 2-row, shrouded header with a 2.50 mm pitch, detent lock, and tin mating finish. The 2842112-2 trades the higher pin count and locking feature for a smaller footprint, gold contacts, and a lower per-contact current ceiling (2 A vs wire-gauge-dependent current). If your board has room for a 2.50 mm pitch and you need vibration-resistant latching, the 1-1871673-2 is the candidate; if you need 2.00 mm density and gold cycle life, 2842112-2 is the fit.
