Key Parameters

Substitute Part Grouping Explanation

Substitution for the 41F39R is based strictly on the following electrical and mechanical parameters:

• Resistance value: 39 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.126" Dia x 0.437" L (3.20mm x 11.10mm)
• Termination count: 2

The substitute part 41F39RE meets these core specifications and is manufactured by the same supplier (Ohmite), ensuring functional equivalence within the defined parameter set.

Parameter Comparison
