Compatibility & Replacements
The RC42GF470J is a direct fit for original equipment specifications requiring 47Ω 2W carbon composition resistors with 5% tolerance. When sourcing replacements, confirm that substitute components match the same resistance value, power rating, tolerance, and axial lead configuration. Allen-Bradley carbon composition resistors are sought after for retrofit projects because their hot-molded construction provides superior pulse withstanding and frequency stability compared to some modern film resistor types, making them preferred in legacy and retrofit applications. Related Allen-Bradley resistor series include the RC32 (1W) and RC20 (0.5W) families with comparable lead terminations and tolerance ratings.
