What This 2.54mm Shrouded Header Is
The 70246-1601: It's an active-production part, ROHS3 compliant, and ships in a Box package — no end-of-life risk on this line.
The 2.54mm pitch sets the board footprint — it's the standard 0.100-inch grid, so it routes cleanly on two-layer boards and mates with standard C-Grid receptacle housings.
