Key Parameters

Substitute Part Grouping Explanation

Substitution for the RNF14FTC61R9 is determined by the following critical parameters: resistance value (61.9 Ohms), tolerance (±1%), composition (metal film), and package type (axial). The substitute parts identified maintain these core electrical specifications while offering variations in power rating and operating temperature range.

The CMF5061R900FHEB serves as a manufacturer-recommended direct substitute, maintaining identical resistance, tolerance, power rating, and package configuration while providing enhanced moisture resistance and an extended operating temperature range to 175°C.

The CMF5561R900FHEB functions as an upgrade substitute with doubled power capacity (0.5W versus 0.25W), suitable for applications requiring higher thermal dissipation capability while preserving all other electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The CMF5061R900FHEB is the manufacturer-recommended substitute, offering identical electrical performance to the RNF14FTC61R9 with enhanced moisture resistance and extended operating temperature capability to 175°C. Both parts maintain ROHS3 compliance and ±1% tolerance specifications. This substitute is appropriate for direct replacement in applications where the original part is unavailable.

The CMF5561R900FHEB provides a higher power rating option (0.5W versus 0.25W) while maintaining all other electrical parameters. Selection of this upgrade substitute is appropriate only when circuit design permits the use of a higher power-rated component and when the application benefits from increased thermal dissipation capability.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Can CMF5061R900FHEB replace RNF14FTC61R9 in all applications?

Yes. The CMF5061R900FHEB maintains identical resistance (61.9 Ohms), tolerance (±1%), power rating (0.25W), and axial package configuration. The extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and enhanced moisture resistance provide equivalent or superior performance in standard applications.

When should CMF5561R900FHEB be used instead of CMF5061R900FHEB?

The CMF5561R900FHEB should be selected only when the application circuit design permits use of a 0.5W power-rated component. The doubled power capacity provides increased thermal margin in high-dissipation applications. All other electrical parameters remain identical.

Are there packaging format differences between these parts?

Yes. The RNF14FTC61R9 is supplied in Tape & Reel (TR) format, while both Vishay Dale substitutes (CMF5061R900FHEB and CMF5561R900FHEB) are supplied in Cut Tape (CT) format. This affects handling and assembly processes but does not impact electrical performance.

Do all parts meet the same regulatory compliance standards?

All three parts are ROHS3 compliant and REACH unaffected. Compliance certifications are equivalent across the RNF14FTC61R9 and both substitute options.

What is the temperature coefficient specification for these resistors?

All three parts maintain a temperature coefficient of ±50ppm/°C, ensuring consistent resistance stability across the operating temperature range.
