My 1949 made 8PCS41 cabinet sticker calls for the 8016.
Between it and the other 1949 9PC41 I had one 8016 (probable replacment) and two RCA branded 1B3/8016. The rest were replacment 1B3.

Usually interchangable, but:
8016 = PIV 10,000 max, Ip = 7,6 max ma, average 2 max ma (1942 data)
1B3/8016 = PIV 30,00 max, Ip = 17 max ma, average 2 max ma (1949 data)
1G3/1B3 = PIV 33,000 max, Ip = 35 max ma, average 1.1 max ma (1965 data)
As the tubes improved the PIV increased, the short-flow current increased, but the average-flow current decreased. I would not put a 1G3 in an RCA projection set.
