Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC80R6 is determined by the following critical parameters: resistance value (80.6 Ohms), tolerance (±1%), composition (metal film), temperature coefficient (±50ppm/°C), and package type (axial). All substitute parts must maintain these core electrical specifications.

The substitute parts are grouped into two categories:

Manufacturer Recommended Substitute (Direct Replacement): CMF5080R600FHEB maintains identical electrical specifications including power rating (0.25W), resistance, tolerance, and temperature coefficient. This part is suitable for direct substitution in existing designs.

Upgrade Substitute (Higher Power Rating): CMF5580R600FHEB provides the same electrical specifications with an increased power rating (0.5W) and extended operating temperature range (-55°C ~ 175°C). This part is suitable when design margins or thermal considerations permit higher power dissipation capability.

Parameter Comparison

Engineering Selection Recommendations

CMF5080R600FHEB is the manufacturer-recommended direct replacement for the RNF14FTC80R6. Both parts maintain identical electrical performance with 0.25W power rating and -55°C to 155°C operating range. The CMF5080R600FHEB adds moisture resistance features while maintaining ROHS3 compliance and Active product status. This substitute is appropriate for applications where the original specification must be preserved without modification.

CMF5580R600FHEB is suitable as an upgrade substitute when circuit design permits higher power dissipation. The 0.5W rating provides additional thermal margin, and the extended operating temperature range (-55°C to 175°C) accommodates more demanding environmental conditions. Both Vishay Dale substitutes are ROHS3 compliant and Active status products, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CMF5080R600FHEB be used as a direct replacement for RNF14FTC80R6?

A: Yes. CMF5080R600FHEB maintains identical resistance (80.6 Ohms), tolerance (±1%), power rating (0.25W), temperature coefficient (±50ppm/°C), and axial package type. The part is electrically and mechanically compatible for direct substitution.

Q: What is the difference between CMF5080R600FHEB and CMF5580R600FHEB?

A: Both parts share identical electrical specifications (80.6 Ohms, ±1%, ±50ppm/°C). The primary differences are power rating (0.25W versus 0.5W) and operating temperature range (-55°C to 155°C versus -55°C to 175°C). CMF5580R600FHEB provides higher power dissipation capability and extended temperature performance.

Q: Are the physical dimensions compatible between the main part and substitutes?

A: All three parts use axial package type. Physical dimensions vary: RNF14FTC80R6 is 0.093" Dia x 0.250" L, CMF5080R600FHEB is 0.065" Dia x 0.150" L, and CMF5580R600FHEB is 0.090" Dia x 0.240" L. Verify PCB layout and mechanical clearances before substitution.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. RNF14FTC80R6, CMF5080R600FHEB, and CMF5580R600FHEB are all ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: When should CMF5580R600FHEB be selected over CMF5080R600FHEB?

A: Select CMF5580R600FHEB when circuit analysis indicates power dissipation approaching or exceeding 0.25W, or when operating temperatures may exceed 155°C. The 0.5W rating and extended temperature range provide additional design margin.
