What this 2mm-pitch breakaway header does for your board
The 5176264-6: The through-hole solder termination with 0.102" (2.60 mm) post length fits standard 1.6 mm PCBs, and the 0.157" (4.00 mm) mating pin length provides solid wipe before the push-pull latch engages.
Mating half and build-to-print BOM
Build-to-print needs both halves; the header body alone is the pin side. For vibration-prone environments, confirm the receptacle has a positive lock.
RoHS compliant per TE Connectivity's compliance declaration.
