Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTD41R2 is determined by the following critical parameters:

• Resistance Value: Must be 41.2 Ohms
• Tolerance: Must be ±1% or tighter
• Package Configuration: Must be Axial Through Hole
• Composition: Must be Metal Film
• Compliance: Must maintain ROHS3 and REACH compliance status

The CMF5541R200FHEB qualifies as a substitute based on matching resistance value, tolerance, package type, and composition. This substitute provides enhanced specifications including higher power rating (0.5W vs 0.25W), improved temperature coefficient (±50ppm/°C vs ±100ppm/°C), and extended maximum operating temperature (175°C vs 155°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTD41R2 and CMF5541R200FHEB maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection between these components should be based on application-specific requirements:

The RNF14FTD41R2 is appropriate for standard applications operating within -55°C to 155°C temperature range with power dissipation not exceeding 0.25W.

The CMF5541R200FHEB provides enhanced performance characteristics including doubled power dissipation capability (0.5W), improved temperature stability (±50ppm/°C), extended operating temperature ceiling (175°C), and moisture resistance. This substitute is suitable for applications requiring higher thermal margins, superior frequency stability, or operation in elevated temperature environments.

Both components are axial through-hole metal film resistors with identical resistance values and tolerance specifications, ensuring direct functional compatibility in circuit designs where the enhanced specifications of the substitute do not create adverse effects.

Frequently Asked Questions (FAQ)

Q: Can CMF5541R200FHEB be used as a direct replacement for RNF14FTD41R2?

A: Yes. Both components share identical resistance value (41.2 Ohms), tolerance (±1%), composition (metal film), and axial package configuration. The substitute provides enhanced specifications without compromising compatibility.

Q: What are the physical dimension differences between these parts?

A: RNF14FTD41R2 measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). CMF5541R200FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both dimensions are within typical axial resistor tolerances and do not affect PCB layout compatibility.

Q: Why does the substitute have a lower temperature coefficient?

A: The CMF5541R200FHEB exhibits ±50ppm/°C compared to ±100ppm/°C for the RNF14FTD41R2. This represents improved frequency stability and reduced resistance drift across temperature variations, a characteristic of the Vishay Dale CMF series design.

Q: Are there compliance differences between these parts?

A: No. Both components maintain identical ROHS3 Compliant and REACH Unaffected status. Both are classified under ECCN EAR99 and HTSUS 8533.21.0090.

Q: What is the significance of the higher power rating in the substitute?

A: The CMF5541R200FHEB is rated at 0.5W versus 0.25W for the RNF14FTD41R2. This provides greater thermal headroom and allows operation in applications with higher power dissipation without exceeding component ratings.

Q: Does packaging format differ between these components?

A: The main part is supplied in Tape & Reel (TR) format. The substitute is supplied in Cut Tape (CT) format. Both are standard packaging methods for through-hole axial resistors and do not affect component functionality or circuit performance.
