Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FAD2K26 is determined by the following critical parameters:

• Resistance Value: Must be exactly 2.26 kOhms
• Power Rating: Must be 0.25W (1/4W)
• Package Configuration: Must be Axial through-hole
• Physical Dimensions: Must be 0.093" Dia x 0.250" L (2.35mm x 6.35mm)
• Temperature Coefficient: Must be ±100ppm/°C
• Operating Temperature Range: Must be -55°C to 155°C
• Composition: Must be Metal Film
• Features: Must include Flame Retardant Coating and Safety rating

Tolerance and packaging format (Tape & Box vs. Tape & Reel) are permitted to vary. Tighter tolerance specifications (±0.1% vs. ±1%) represent an upgrade path while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both RNF14FAD2K26 and RNF14BTD2K26 maintain Active product status and full ROHS3 compliance. The RNF14BTD2K26 provides improved tolerance specification (±0.1% vs. ±1%) while maintaining identical electrical performance, thermal characteristics, and mechanical form factor. Selection between these parts depends on packaging requirements: Tape & Box format for the main part or Tape & Reel format for the substitute. Both components are suitable for direct substitution in applications where the tighter tolerance of the RNF14BTD2K26 does not create cost or procurement constraints.

Frequently Asked Questions (FAQ)

Q: Can RNF14BTD2K26 replace RNF14FAD2K26 in existing designs?

A: Yes. The RNF14BTD2K26 is electrically and mechanically identical to the RNF14FAD2K26 with the exception of improved tolerance (±0.1% vs. ±1%) and packaging format (Tape & Reel vs. Tape & Box). The tighter tolerance represents an upgrade that maintains full backward compatibility.

Q: What is the difference between Tape & Box and Tape & Reel packaging?

A: Tape & Box (TB) packaging provides resistors on tape with a protective box for manual handling and smaller quantity orders. Tape & Reel (TR) packaging provides resistors on continuous tape wound on a reel, optimized for automated assembly equipment and higher volume production runs.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical axial package dimensions of 0.093" Dia x 0.250" L (2.35mm x 6.35mm), ensuring direct mechanical compatibility in PCB layouts and through-hole applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RNF14FAD2K26 and RNF14BTD2K26 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8533.21.0090).

Q: What is the significance of the tolerance difference?

A: The RNF14BTD2K26 tolerance of ±0.1% provides tighter resistance value control compared to the ±1% tolerance of the RNF14FAD2K26. This upgrade is beneficial in precision analog circuits, measurement equipment, and applications requiring strict component value matching.
