Overview
The Allen-Bradley RCR42G106JS is a military-specification 2-watt carbon composition resistor designed for demanding industrial applications. With a nominal resistance of 10Ω and ±5% tolerance, this component delivers the reliability and consistency required in control panel builds, equipment repairs, and retrofit projects. The RCR series designation indicates military-grade performance, making these resistors a preferred choice for long-term circuit stability.

Compatibility & Replacements
The RCR42G106JS is part of Allen-Bradley’s RCR42 series 2-watt carbon composition line. Direct functional equivalents in the same series include other RCR42 part numbers with different resistance values (e.g., RCR42G100JS for 10Ω, RCR42G220JS for 22Ω). For drop-in replacement, verify the exact resistance value and tolerance required by your application. Stackpole, Ohmite, and other legacy manufacturers produced similar MIL-R-39008 compliant 2-watt carbon composition resistors; however, Allen-Bradley original components are recommended for critical industrial applications where documented long-term stability is required.
