Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC34R0 is determined by the following critical parameters:

• Resistance Value: Must be 34 Ohms
• Tolerance: Must be ±1% or tighter
• Composition: Metal film construction required
• Package Type: Axial through-hole configuration
• Temperature Coefficient: ±50ppm/°C or better
• Compliance: ROHS3 compliant, REACH unaffected

The CMF5534R000FHEB qualifies as a substitute because it maintains identical resistance, tolerance, composition, and package type. The substitute offers enhanced power rating (0.5W versus 0.25W) and extended operating temperature range (-55°C to 175°C versus -55°C to 155°C), providing design flexibility for applications with higher thermal or power dissipation requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC34R0 and CMF5534R000FHEB meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The CMF5534R000FHEB provides additional design margin through higher power dissipation capability (0.5W versus 0.25W) and extended maximum operating temperature (175°C versus 155°C). Selection between these parts depends on application thermal environment and power budget constraints. Both parts maintain identical electrical performance in resistance value, tolerance, and temperature coefficient, ensuring functional equivalence in circuits designed for the RNF14FTC34R0 specifications.

Frequently Asked Questions (FAQ)

Q: Can the CMF5534R000FHEB replace the RNF14FTC34R0 in existing designs?

A: Yes. Both parts share identical resistance (34 Ohms), tolerance (±1%), composition (metal film), and axial package configuration. The substitute offers higher power rating and extended temperature range, making it suitable for applications originally specified for the RNF14FTC34R0.

Q: What is the difference in physical dimensions between these parts?

A: The RNF14FTC34R0 measures 0.093" diameter × 0.250" length (2.35mm × 6.35mm). The CMF5534R000FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both are axial through-hole components with compatible PCB footprints.

Q: Are there packaging format differences?

A: The RNF14FTC34R0 is supplied in Tape & Reel (TR) format, while the CMF5534R000FHEB is supplied in Cut Tape (CT) format. This affects procurement and assembly processes but does not impact electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RNF14FTC34R0 and CMF5534R000FHEB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the temperature coefficient specification for both parts?

A: Both parts have a temperature coefficient of ±50ppm/°C, ensuring equivalent stability across temperature variations in the specified operating ranges.
