The 4-103185-0-19: The breakaway construction means the strip can be snapped to the required position count, though this variant ships as a fixed 19-position loaded header. The unshrouded design exposes the pins for direct mating with receptacles or crimp housings, but offers no keying or polarization — alignment depends on the mating connector's shroud.
Plating and Contact Durability
The post finish is 100 µinch tin-lead, which provides a reliable solder joint in through-hole assembly and is compatible with leaded solder processes. For applications near the upper temperature limit, derate the current per the AMPMODU Mod II derating curve in the product drawing.
The base product number is 103185. The -0-19 suffix indicates the 19-position variant in the breakaway header family. No direct pin-compatible replacement is listed by the manufacturer — confirm the BOM position count and mating half before committing.
