What This Header Needs to Fit
The 1456819-3 is a pin header from TE Connectivity AMP Connectors, shipped in Bulk — loose pieces, not tape-and-reel, so plan for manual or tube-fed placement on the line. Base product number 1456819 ties this to a family of headers — use it to locate mating receptacles, crimp terminals, and housing accessories that share the same footprint.
