The 1-146257-0 is a 20-position, dual-row breakaway header from the TE AMPMODU Mod II series, unshrouded with push-pull fastening for board-to-board or cable mating.
No pin-compatible successor is listed from the original manufacturer. A board redesign to a current AMPMODU Mod II or other 0.100" pitch header is the functional path forward.
No pin-compatible alternative is documented by TE Connectivity for this Obsolete part.
