Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTD196R is determined by the following critical parameters:

• Resistance Value: Must be 196 Ohms
• Tolerance: Must be ±1% or tighter
• Composition: Must be Metal Film
• Package Type: Must be Axial through-hole
• Compliance: Must maintain ROHS3 compliance and REACH Unaffected status

The CMF55196R00FHEB from Vishay Dale satisfies all substitution criteria. While this part features a higher power rating (0.5W vs 0.25W), enhanced temperature coefficient (±50ppm/°C vs ±100ppm/°C), and extended operating temperature range (-55°C ~ 175°C vs -55°C ~ 155°C), these represent performance improvements rather than deviations. The axial package geometry remains compatible with existing PCB layouts designed for the RNF14FTD196R.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTD196R and CMF55196R00FHEB maintain Active product status and full regulatory compliance under ROHS3 and REACH standards. Selection between these parts should be based on application-specific requirements:

The RNF14FTD196R is appropriate for applications where the 0.25W power rating is sufficient and the standard temperature coefficient of ±100ppm/°C meets circuit accuracy requirements.

The CMF55196R00FHEB provides enhanced performance margins through increased power dissipation capability (0.5W), improved temperature stability (±50ppm/°C), extended operating temperature range to 175°C, and additional moisture resistance. These characteristics make it suitable for applications requiring higher reliability or operation in elevated temperature environments. The slightly reduced physical dimensions (0.090" diameter vs 0.093") may provide minor PCB layout advantages.

Frequently Asked Questions (FAQ)

Q: Can CMF55196R00FHEB be used as a direct replacement for RNF14FTD196R?

A: Yes. Both parts share identical resistance (196 Ohms) and tolerance (±1%), metal film composition, and axial package configuration. The CMF55196R00FHEB's higher power rating and improved temperature coefficient represent performance enhancements compatible with existing designs.

Q: What are the physical dimension differences?

A: The RNF14FTD196R measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). The CMF55196R00FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both are axial through-hole components with standard lead spacing suitable for conventional PCB layouts.

Q: Are there packaging format differences?

A: The RNF14FTD196R is supplied in Tape & Reel (TR) format, while the CMF55196R00FHEB is supplied in Cut Tape (CT) format. This affects procurement and assembly processes but does not impact component performance or compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RNF14FTD196R and CMF55196R00FHEB are ROHS3 Compliant and REACH Unaffected, meeting current environmental and safety standards.

Q: What is the significance of the temperature coefficient difference?

A: The CMF55196R00FHEB features a temperature coefficient of ±50ppm/°C compared to the RNF14FTD196R's ±100ppm/°C. This means the CMF55196R00FHEB exhibits superior resistance stability across temperature variations, beneficial for precision analog circuits and temperature-sensitive applications.

Q: Can the RNF14FTD196R be used in applications requiring the 0.5W power rating?

A: No. The RNF14FTD196R is rated for 0.25W maximum power dissipation. Applications requiring 0.5W capability must use the CMF55196R00FHEB or equivalent higher-rated component.
