Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FAD82R5 are classified based on the following allowed electrical and mechanical parameters:

Direct Substitutes (Same Electrical Specifications):

• Resistance value: 82.5 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial
• Operating temperature range: -55°C ~ 155°C minimum
• Temperature coefficient: ±100ppm/°C or better
• Compliance: ROHS3 Compliant

Upgrade Substitutes (Enhanced Specifications):

• Same resistance and tolerance as above
• Higher power rating (0.5W or greater) for thermal margin
• Improved temperature coefficient (lower absolute value)
• Extended operating temperature range
• Same axial package compatibility
• ROHS3 Compliant

The RNF14FTD82R5 qualifies as a direct substitute with identical electrical specifications but different packaging format (Cut Tape vs. Tape & Box). The CMF5582R500FHEB qualifies as an upgrade substitute with enhanced power rating and temperature coefficient while maintaining electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

RNF14FTD82R5 Selection Criteria: Use RNF14FTD82R5 when Cut Tape packaging format is required for automated assembly processes or when inventory from this packaging variant is preferred. Electrical and thermal performance are identical to RNF14FAD82R5. Both parts maintain Active product status and ROHS3 compliance.

CMF5582R500FHEB Selection Criteria: Use CMF5582R500FHEB when enhanced thermal performance or extended operating temperature range is required. The 0.5W power rating provides additional thermal margin compared to the 0.25W rating of RNF14FAD82R5. The ±50ppm/°C temperature coefficient offers improved stability over the ±100ppm/°C specification. Operating temperature extends to 175°C versus 155°C. All parts maintain Active product status and ROHS3 compliance. Axial package compatibility is maintained across all three parts.

Frequently Asked Questions (FAQ)

Q: Can RNF14FTD82R5 be used as a direct replacement for RNF14FAD82R5? A: Yes. Both parts share identical electrical specifications: 82.5 Ohms ±1%, 0.25W power rating, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The difference is packaging format only (Cut Tape versus Tape & Box). Axial package compatibility is maintained.

Q: What is the advantage of using CMF5582R500FHEB over RNF14FAD82R5? A: CMF5582R500FHEB provides two key enhancements: doubled power rating (0.5W versus 0.25W) for improved thermal margin, and superior temperature coefficient (±50ppm/°C versus ±100ppm/°C) for better frequency stability. Operating temperature range extends to 175°C. Resistance value and tolerance remain identical at 82.5 Ohms ±1%.

Q: Are all three parts compatible with the same PCB footprint? A: Yes. All three parts use axial package configuration with identical lead termination count (2 terminations). Physical dimensions are comparable: RNF14FAD82R5 and RNF14FTD82R5 are 0.093" Dia x 0.250" L, while CMF5582R500FHEB is 0.090" Dia x 0.240" L. These minor dimensional variations do not affect PCB footprint compatibility for standard axial resistor layouts.

Q: Do all substitute parts meet the same compliance requirements? A: Yes. RNF14FAD82R5, RNF14FTD82R5, and CMF5582R500FHEB are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All parts maintain Active product status.

Q: When should packaging format (Tape & Box versus Cut Tape) influence part selection? A: Packaging format selection depends on assembly process requirements. Tape & Box (TB) format is suitable for manual assembly or lower-volume applications. Cut Tape (CT) format is optimized for automated pick-and-place assembly systems. Electrical performance is identical between formats.
