Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTD2K26 is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 2.26 kOhms
• Power rating: 0.25W (1/4W)
• Package type: Axial
• Physical dimensions: 0.093" Dia × 0.250" L
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• Compliance: ROHS3 Compliant, REACH Unaffected

Variable Parameters (Allowed to Differ):

• Tolerance specification (±1% or tighter)
• Inventory availability
• Specific product series designation within manufacturer portfolio

The RNF14BTD2K26 qualifies as a substitute part by maintaining all critical parameters while offering improved tolerance specification (±0.1% versus ±1%), representing an upgrade path for applications requiring higher precision without component redesign.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTD2K26 and RNF14BTD2K26 maintain Active product status and full compliance with ROHS3 and REACH requirements, ensuring long-term component availability and regulatory adherence. Selection between these parts depends on circuit tolerance requirements:

The RNF14FTD2K26 (±1% tolerance) is suitable for general-purpose applications where standard tolerance specifications meet design margins. The RNF14BTD2K26 (±0.1% tolerance) provides enhanced precision for circuits requiring tighter resistance value control, such as precision measurement, signal conditioning, or feedback network applications. Both components are mechanically and electrically interchangeable within the same PCB footprint and thermal environment. Higher inventory availability of the RNF14BTD2K26 may support supply chain continuity for high-volume production requirements.
