Overview
The Allen-Bradley RCR07G335JS is a military-spec carbon composition resistor featuring a 3.3 megohm (3.3MΩ) resistance value, 1/4 watt (0.25W) power rating, and ±5% tolerance. Built to MIL-R-39008 specifications, this component is part of Allen-Bradley’s RCR07G series of established-reliability resistors. The axial lead termination and rugged hot-molded carbon construction make it suitable for industrial control systems, test equipment, and legacy circuit board repairs where original component authenticity and performance are critical.

Compatibility & Replacements
Allen-Bradley carbon composition resistors of this military grade are difficult to replace with modern alternatives while maintaining circuit behavior. Direct substitution with film or wirewound resistors is not recommended without circuit analysis, as carbon composition resistors exhibit unique frequency response and pulse-handling characteristics. For restoration work, the original Allen-Bradley RCR07G335JS is the preferred choice. Distributors and cross-reference guides (such as Vishay Dale) provide film resistor equivalents for applications where design flexibility exists, but for sensitive circuits, original components ensure authentic performance restoration.
