Board Fit: Pitch and Position Count
Current and Contact Reality
Rated 3A per contact at 25°C ambient — this is a signal-level current, not power delivery. Tin-on-tin mating finish (100µin) handles moderate mating cycles; for high-cycle or corrosive environments, consider gold-plated siblings in the same series.
Peer Comparison: Why Not the Others
The closest functional second-source is 1394090-1, but it uses a 0.112" pitch and 6 positions — not pin-compatible. 1-1871673-2 has 4 positions with a board lock, and 953440-3 is a 6-position automotive header with different keying. Neither drops into the same footprint.
