Mr. Han, a longtime Samsung executive, has overseen the company's consumer electronics business since 2021.
Han Chung-hee, co-chief executive of Samsung Electronics and a nearly four-decade veteran of the South Korean consumer technology giant, died on Tuesday.
Mr Khan, 63, suffered a sudden heart attack, a company spokesman said.
Mr Han shared the CEO role with the head of Samsung's semiconductor business since 2022, and was also a board member. He ran Samsung's consumer electronics business since 2021, adding the digital instrumentation operation to his brief a year later. He previously oversaw the group that makes visual displays for a wide range of Samsung electronics devices.
Mr. Han graduated from Inha University in Incheon, South Korea, with a degree in electrical engineering. He joined Samsung in 1988, shortly after the death of its founder Lee Byung-chul, during a pivotal period in the company's history.
Mr. Lee's son and successor relentlessly pushed Samsung to overcome the technological changes of the 1990s and 2000s to become a leader in the flat-panel display and mobile phone markets.
Samsung is the largest and most successful of the conglomerates known as chaebols that have transformed South Korea's economy into a global export engine. Samsung Electronics is a significant exports. Samsung is one of the most popular brands in the global smartphone market, where it competes with Apple and Xiaomi. It is also the world's largest maker of memory chips, used in everything from electric cars and smartwatches to cutting-edge artificial intelligence servers.
Mr Khan is survived by his wife and three children, the company said.
The company added that there are no plans yet regarding who will succeed him at Samsung.
