Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTD3R01 is determined by the following critical parameters:

• Resistance value: 3.01 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Power rating may exceed the original specification when all other parameters are maintained. Operating temperature range may be extended beyond the original specification when all other parameters are maintained. Physical dimensions may vary within standard axial package tolerances.

Parameter Comparison

Engineering Selection Recommendations

The CPF13R0100FKEE6 qualifies as a direct substitute for the RNF14FTD3R01 based on matching electrical specifications: identical resistance value (3.01 Ohms), tolerance (±1%), composition (metal film), temperature coefficient (±100ppm/°C), and package configuration (axial). Both components maintain ROHS3 compliance and Active product status.

The substitute part provides enhanced power dissipation capability (1W versus 0.25W) and extended operating temperature range (-65°C ~ 230°C versus -55°C ~ 155°C), which represents a functional upgrade within the same component category. Physical dimensions remain within standard axial package specifications.

Frequently Asked Questions (FAQ)

Q: Can CPF13R0100FKEE6 replace RNF14FTD3R01 in all applications?

A: Yes, when the application circuit design accommodates the substitute part's specifications. The CPF13R0100FKEE6 maintains identical electrical parameters (resistance, tolerance, temperature coefficient) and package type. The higher power rating (1W) and extended temperature range represent functional improvements that do not restrict compatibility.

Q: What are the physical dimension differences?

A: RNF14FTD3R01 dimensions are 0.093" Dia x 0.250" L (2.35mm x 6.35mm). CPF13R0100FKEE6 dimensions are 0.090" Dia x 0.240" L (2.29mm x 6.10mm). Both are standard axial package configurations with minor dimensional variation within normal manufacturing tolerances.

Q: Are both parts RoHS compliant?

A: Yes. Both RNF14FTD3R01 and CPF13R0100FKEE6 are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the difference in packaging format?

A: RNF14FTD3R01 is supplied in Tape & Reel (TR) format. CPF13R0100FKEE6 is supplied in Cut Tape (CT) format. Both formats are standard for through-hole resistor distribution and do not affect component functionality.

Q: Can the substitute part handle higher temperatures?

A: Yes. CPF13R0100FKEE6 operates across -65°C ~ 230°C, compared to RNF14FTD3R01 range of -55°C ~ 155°C. This extended range provides additional design margin for applications requiring operation at elevated temperatures.
