Compatibility & Replacements
The RCR07G226JS is manufactured to MIL-R-39008 specifications for established reliability. While direct interchangeability with modern film resistors exists, these carbon composition units preserve the exact electrical and mechanical characteristics of original designs. When upgrading legacy systems, film resistor equivalents such as Vishay Dale RWR or RLR series may be suitable alternatives, though differences in temperature coefficient and noise characteristics should be evaluated for your specific application. For exact replacements in critical systems, Allen-Bradley carbon composition resistors remain the preferred choice. Confirm availability and lead times before specifying replacements in new designs.
