Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC113R is determined by the following critical parameters:

• Resistance Value: Must be 113 Ohms
• Tolerance: Must be ±1% or tighter
• Composition: Metal film construction required
• Package: Axial through-hole configuration
• Temperature Coefficient: ±50ppm/°C or better
• Compliance: ROHS3 Compliant, REACH Unaffected

The CMF55113R00FHEB from Vishay Dale meets all substitution criteria. While this part features a higher power rating (0.5W vs 0.25W), it maintains identical electrical specifications for resistance, tolerance, and temperature coefficient. The increased power dissipation capability provides design margin without compromising circuit function. Both parts share identical axial package geometry compatibility and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC113R and CMF55113R00FHEB maintain Active product status with full ROHS3 compliance and REACH Unaffected classification, ensuring regulatory alignment for current and future applications. The CMF55113R00FHEB provides extended operating temperature capability to 175°C and includes moisture-resistant features, offering enhanced environmental protection. Selection between these parts depends on application power dissipation requirements and thermal environment specifications. The substitute part's higher power rating accommodates designs with greater current flow or elevated ambient temperatures without performance degradation.

Frequently Asked Questions (FAQ)

Can the CMF55113R00FHEB replace the RNF14FTC113R in existing designs?

Yes. Both parts share identical resistance (113 Ohms), tolerance (±1%), temperature coefficient (±50ppm/°C), and axial package configuration. The substitute's higher power rating (0.5W vs 0.25W) provides additional thermal margin without affecting electrical performance.

What are the physical dimension differences?

The RNF14FTC113R measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). The CMF55113R00FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both dimensions are compatible with standard axial component PCB layouts and through-hole spacing.

Are there compliance differences between these parts?

No. Both parts are ROHS3 Compliant and REACH Unaffected. The CMF55113R00FHEB adds moisture-resistant features, providing additional environmental protection without changing regulatory status.

What is the temperature range difference?

The RNF14FTC113R operates from -55°C to 155°C. The CMF55113R00FHEB extends the upper limit to 175°C, allowing use in higher-temperature applications while maintaining the same lower temperature specification.

Does packaging format affect substitution?

The main part is supplied in Tape & Reel (TR) format with 807 units in stock. The substitute is supplied in Cut Tape (CT) format with 1825 units available. Packaging format does not affect component performance or PCB compatibility; selection depends on procurement and assembly process requirements.
