Key Parameters

Substitute Part Grouping Explanation

Substitution of the RNF14CTD200R is based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 200 Ohms (exact match required)
• Package type: Axial through-hole (mechanical compatibility)
• Composition: Metal film (performance class equivalence)
• Compliance: ROHS3 and REACH status alignment

Allowable Parameter Variations:

• Tolerance: May be equal or tighter (±0.25% or better)
• Power rating: May be equal or higher (0.25W or greater)
• Temperature coefficient: May be equal or lower in absolute value
• Operating temperature range: May be equal or extended
• Physical dimensions: Minor variations acceptable within axial package constraints

The CMF55200R00BHEB qualifies as a substitute because it maintains the 200 Ohm resistance value, axial package configuration, metal film composition, and compliance certifications while offering improved tolerance (±0.1%), higher power rating (0.5W), and lower temperature coefficient (±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14CTD200R and CMF55200R00BHEB are active production components with full ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications.

The RNF14CTD200R is the primary selection when the specified 0.25W power rating and ±0.25% tolerance are design requirements and when Stackpole Electronics Inc sourcing is preferred.

The CMF55200R00BHEB serves as a substitute when higher performance margins are acceptable or required. The improved tolerance (±0.1%), increased power rating (0.5W), lower temperature coefficient (±50ppm/°C), extended operating temperature range (-55°C ~ 175°C), and moisture resistant feature provide enhanced reliability in demanding environments. The slightly smaller physical dimensions (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L) remain compatible with standard axial component PCB layouts.

Both parts are metal film axial resistors with flame retardant coating and safety features, ensuring functional equivalence in circuit applications where the 200 Ohm resistance value is specified.

Frequently Asked Questions (FAQ)

Q: Can CMF55200R00BHEB directly replace RNF14CTD200R in all applications?

A: Yes, for applications where the circuit design specifies 200 Ohm resistance with axial package configuration. The CMF55200R00BHEB offers equal or superior electrical performance across all critical parameters. Physical dimensions are slightly smaller but remain compatible with standard through-hole PCB layouts designed for axial resistors.

Q: What are the key differences between these two parts?

A: The primary differences are tolerance (±0.1% versus ±0.25%), power rating (0.5W versus 0.25W), temperature coefficient (±50ppm/°C versus ±100ppm/°C), and operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). The CMF55200R00BHEB also includes moisture resistant features. Both maintain identical 200 Ohm resistance and axial package type.

Q: Are there packaging format differences?

A: Yes. The RNF14CTD200R is supplied in Tape & Reel (TR) format, while the CMF55200R00BHEB is supplied in Cut Tape (CT) format. This affects handling and assembly processes but does not impact component functionality.

Q: Do both parts meet compliance requirements?

A: Yes. Both the RNF14CTD200R and CMF55200R00BHEB are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for controlled substance restrictions.

Q: Which part should be selected for high-precision applications?

A: The CMF55200R00BHEB is the appropriate selection for high-precision applications due to its tighter tolerance of ±0.1% compared to the RNF14CTD200R tolerance of ±0.25%.

Q: Are there thermal performance differences?

A: Yes. The CMF55200R00BHEB has a lower temperature coefficient (±50ppm/°C) and extended operating temperature range (-55°C ~ 175°C) compared to the RNF14CTD200R (±100ppm/°C, -55°C ~ 155°C). This provides better stability across temperature variations.
