Overview
The Allen-Bradley RCR42G200JS is a 20Ω 2W carbon composition resistor with ±5% tolerance, designed to military specifications for demanding industrial and electronic applications. RCR42G200JS resistors deliver the legendary reliability and stability Allen-Bradley is known for, making them a trusted choice for controls engineers, maintenance technicians, and system integrators working with legacy and modern equipment.
Key Features
- MIL-SPEC Grade-S Rated: Military type designation starting with RCR indicates the highest grade of Allen-Bradley resistors, ensuring superior performance and traceability.
- Oxygen-Free Copper Leads: Leads are oxygen-free copper for robust soldering and long-term reliability without oxidation.
- Hot-Molded Carbon Construction: Hot-moulded carbon resistors consist of a solid cylindrical carbon resistive element with leads embedded at each end, making them rugged and highly reliable with non-magnetic and non-inductive characteristics.
- High Pulse Withstanding Capability: Allen Bradley Carbon Composition Resistors are highly recognized for pulse withstanding and power dissipation in transient-heavy circuits.
- Made in USA: Made in USA with strict quality control standards.
- Low Inductance & High-Frequency Stability: Ideal for RF, audio, and precision measurement circuits where noise performance matters.

Compatibility & Replacements
The RCR42G200JS is a legacy part still sought after for its MIL-SPEC reliability and sonic qualities in analog circuits. While direct modern equivalents exist (such as metal film or wirewound 20Ω 2W resistors), engineers often specify the original Allen-Bradley carbon composition type for historical accuracy, low-noise performance, and established circuit performance. Stock this part for immediate dispatch to repair technicians and system integrators requiring authentic replacement components. Minimum order quantities apply; verify current inventory before ordering.
