No official successor is listed; cross-referencing to a current BergStik header with the same 36 positions, single row, 0.100\" pitch, and gold plating is the recommended path.","metaTitle":"77311-125-36 BergStik Header – Obsolete, 36-Pin","metaDescription":"77311-125-36 BergStik unshrouded header, 36 positions, single row, 0.100\" pitch.
