Key Parameters

Substitute Part Grouping Explanation

The Ohmite 41F22RE qualifies as an equivalent substitute for the 41J22RE based on the following critical parameters:

• Resistance Value: Both parts are 22 Ohms
• Power Rating: Both are rated at 1W
• Composition: Both are wirewound construction
• Package Type: Both use axial through-hole packaging
• Physical Dimensions: Identical at 0.126" Dia × 0.437" L (3.20mm × 11.10mm)
• Temperature Coefficient: Both maintain ±20ppm/°C stability
• Terminations: Both have 2 terminations
• Compliance: Both are RoHS compliant

The primary difference is tolerance specification: the 41F22RE offers ±1% tolerance compared to the 41J22RE's ±5% tolerance, making it suitable for applications requiring tighter resistance accuracy while maintaining all other electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 41J22RE and 41F22RE are active products from Ohmite's Ohmicone® 40 series and maintain full RoHS compliance. The 41J22RE with ±5% tolerance is suitable for general-purpose applications where standard resistance accuracy is acceptable. The 41F22RE with ±1% tolerance is appropriate for precision circuits requiring tighter resistance specifications. Both parts share identical electrical performance characteristics, physical dimensions, and thermal properties, ensuring direct mechanical and electrical interchangeability in axial through-hole PCB layouts. Selection between these parts depends solely on the tolerance requirement of the specific application circuit.
