Overview
The Allen-Bradley RC32GF241J is a fixed carbon composition resistor designed for industrial control circuits, legacy equipment, and applications requiring dependable fixed resistance. Rated at 240 ohms with ±5% tolerance and 1-watt power dissipation, this resistor combines proven durability with the pulse-withstanding capability characteristic of hot-molded construction. Allen-Bradley carbon composition resistors remain preferred in retrofit and maintenance applications where original component specifications must be matched.
Key Features
- Resistance Value: 240 ohms nominal
- Power Rating: 1 watt at 50% rated wattage
- Tolerance: ±5% per industrial classification
- Construction: Hot-molded carbon composition with embedded leads
- Temperature Range: Rated to 70°C ambient
- Oxygen-Free Copper Leads: Corrosion-resistant termination for extended reliability
Technical Specifications
The RC32 series designation identifies this component as a 1-watt fixed resistor within Allen-Bradley’s industrial carbon composition lineup. Part number decoding: RC=resistor type, 32=1-watt series, GF=240 ohm value (first two digits × 0.1), 241=base code, J=5% tolerance. Operating temperature range to 70°C ensures stable resistance in cabinet and enclosure environments. The hot-molded construction minimizes lead separation and provides superior mechanical robustness compared to rolled-carbon designs.
Typical Applications
- PLC input/output protection circuits and signal conditioning
- Drive and motor control bias networks
- Instrumentation and measurement equipment
- Legacy industrial panel retrofit and maintenance
- Circuit board rework where original component values must be maintained
- Gate drive and logic level termination resistors
Compatibility & Replacements
The RC32GF241J is part of Allen-Bradley’s long-established carbon composition resistor portfolio. While modern thin-film and metal-oxide alternatives offer lower noise and tighter tolerances, this component remains standard for systems designed around 5% tolerance and hot-molded carbon reliability. Equivalent 240Ω ±5% 1W modern replacements exist from Vishay (Dale RN series), Stackpole, or Ohmite, though compatibility verification with the original equipment manufacturer is recommended. NOS (New Old Stock) units like this are in limited supply; most North American production ceased in the 1990s.
