The 7-146277-2: This is a 22-position, single-row unshrouded breakaway header from the AMPMODU Mod II series. The breakaway construction means the 22-position strip can be snapped to shorter lengths if needed, though this part ships fully populated with all positions loaded.
Contact Rating and Plating
The tin-plated solder tail (100 µinch) is standard for wave-solder wetting and does not limit the mating cycle count.
The base product number is 146277; this specific variant includes the gold mating finish and tin post. No official pin-compatible replacement or cross-reference is listed by the manufacturer — the BOM position should be matched to this exact order code.
