Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC115K is determined by the following critical parameters:

• Resistance value: 115 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant (minimum requirement)

The CMF55115K00FHEB from Vishay Dale meets all electrical specifications and mechanical compatibility criteria. While this substitute features a higher power rating (0.5W vs 0.25W) and extended operating temperature range (-55°C ~ 175°C vs -55°C ~ 155°C), these represent performance enhancements that do not compromise compatibility in applications designed for the RNF14FTC115K.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC115K and CMF55115K00FHEB maintain Active product status and full ROHS3 compliance. The CMF55115K00FHEB is suitable for direct substitution based on matching electrical parameters (resistance, tolerance, temperature coefficient) and identical axial package configuration. The higher power rating and extended temperature range of the substitute provide additional design margin without introducing incompatibility. Both components carry REACH Unaffected status and identical ECCN/HTSUS classifications, ensuring regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can CMF55115K00FHEB replace RNF14FTC115K in existing designs?

A: Yes. Both components share identical resistance (115 kOhms), tolerance (±1%), composition (metal film), temperature coefficient (±50ppm/°C), and axial package configuration. The substitute's higher power rating (0.5W vs 0.25W) and extended operating temperature range (-55°C ~ 175°C) do not create compatibility issues.

Q: What is the difference in physical dimensions?

A: RNF14FTC115K measures 0.093" Dia x 0.250" L (2.35mm x 6.35mm). CMF55115K00FHEB measures 0.090" Dia x 0.240" L (2.29mm x 6.10mm). Both are axial through-hole components with minimal dimensional variation suitable for standard PCB layouts.

Q: Are there packaging differences?

A: RNF14FTC115K is supplied in Tape & Reel (TR) packaging. CMF55115K00FHEB is supplied in Cut Tape (CT) packaging. Both formats are standard for through-hole resistor distribution and do not affect component performance or installation.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 Compliant, REACH Unaffected, and classified under identical ECCN (EAR99) and HTSUS (8533.21.0090) codes.

Q: What is the temperature coefficient significance?

A: Both parts maintain ±50ppm/°C temperature coefficient, ensuring equivalent resistance stability across temperature variations. This parameter is critical for precision applications and is identical between the main part and substitute.
