In my view, no ac has ever replaced the DC-3.
As the DC-3 was produced by the thousands during the war, it came cheap and handy after the war.
Almost all airlines used it.
Any replacement at the time had to be better, i.e. different (more power, turbos, more load, more comfort,...).
A real replacement of the DC-3 in terms of performances (25 pax, 2-3t payload depending on the range) came later in the shape of the Short SC
-7 Skyvan and the Nord 262. But they were not mass produced and they were not cheap.
All the others, Handley-Page Herald, Vickers Viscount, Fokker F-27/Fairchild-Hiller F-227, Convair 240 to 640, Hawker-Siddeley 748, NAMC YS
-11, Antonov An-24, had at least twice as much passengers as the DC-3
