Compatibility & Replacements
The RCR20G222JS is a direct replacement for equivalent Allen-Bradley 2.2kΩ 1/2W 5% composition resistors. While carbon composition resistors are no longer manufactured by most suppliers, the RCR20G222JS remains the industry standard for MIL-SPEC compliance in legacy and aerospace systems. For modern designs, metal film or thick-film alternatives may offer improved tolerance and temperature coefficients; however, direct substitution into existing boards requires no PCB modification. Verify mounting and pinout compatibility before installation in safety-critical applications.
