Compatibility & Replacements
The RCR07G560JS is a direct replacement for other Allen-Bradley RCR07 series 56-ohm resistors with equivalent specifications. It is compatible with any circuit calling for a 0.25W, 56-ohm, 5% carbon composition resistor with through-hole axial leads. When specifying replacements, verify tolerance and power rating requirements; this unit’s 5% tolerance and 1/4W rating make it suitable for general-purpose industrial circuits. NOS (new, old stock) units may require a brief oven treatment at 80°C to remove atmospheric moisture and achieve stated tolerance specs.
