Overview
The Allen-Bradley RCR42GF470J is a 47Ω, 2-watt carbon composition resistor with ±5% tolerance. This military-grade fixed resistor (RCR series) combines proven Allen-Bradley quality with robust construction suitable for industrial controls, test equipment, and precision electronic circuits. The axial-lead format and carbon composite resistive element provide excellent reliability and minimal noise performance.
Key Features
- Military-grade RCR series designation for superior screening and quality assurance
- Hot-molded carbon composite resistive element with embedded axial leads
- Oxygen-free copper leads for corrosion resistance and long service life
- Non-magnetic and non-inductive construction—ideal for sensitive analog circuits
- Stable performance across industrial temperature range (0–70°C ambient)
- ±5% resistance tolerance for precision circuit design

Compatibility & Replacements
The Allen-Bradley RCR42GF470J is part of the wider RCR carbon composition family. Modern alternatives include thin-film metal-oxide and metal-film resistors, though for legacy equipment or noise-critical circuits, original Allen-Bradley carbon composition resistors are often preferred. Always verify circuit requirements and tolerance bands before substituting. This New Old Stock (NOS) part is ideal for maintaining original specifications in vintage industrial controls and audio equipment.
