What This Breakaway Header Does for a Board
The 9-146285-0-04: The breakaway construction means you can snap individual pin sections from a longer strip — handy for prototyping or when you need an odd position count that isn't a standard part number.
If you're counting on 500+ mating cycles, the thicker gold on 9-146285-0-04 is the safer choice.
This is a through-hole solder-terminated header. The 0.090" (2.29mm) post length is short — it's meant for a standard 0.062" PCB with a thin solder fillet. It mates with any AMPMODU Mod II female socket or crimp receptacle that accepts a 0.025" square post.
