The 0022288053: The breakaway design means you can snap the strip to exactly 5 positions — or any length from 1 to 40 — reducing inventory complexity across multiple BOM lines. Gold plating on the mating face (15.0µin) ensures reliable signal contact over repeated mating cycles, while the tin-plated posts (100.0µin) solder cleanly into plated through-holes.
The pitch is 0.100" (2.54mm) — standard for prototyping and dense signal routing.
No, it is unshrouded — the male pins are exposed for mating with a receptacle housing.
It mates with a KK254 series crimp receptacle housing (e.g., Molex 50-57-9405 or similar 5-position housing) using the matching crimp terminals.
