Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC115R are qualified based on the following electrical and mechanical parameters:

• Resistance value: 115 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Package type: Axial through-hole (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (minimum requirement)

The CMF50115R00FHEB from Vishay Dale meets all electrical specifications and compliance requirements. Physical dimensions differ due to manufacturing design variations within the axial package category, but both components are compatible with standard through-hole PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC115R and CMF50115R00FHEB are Active products with full ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement. The CMF50115R00FHEB provides an extended operating temperature range to 175°C and includes moisture-resistant features, offering enhanced environmental performance. Selection between these parts should be based on packaging requirements (Tape & Reel versus Cut Tape format), inventory availability, and specific application temperature demands. Both components are electrically and mechanically interchangeable for standard through-hole PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CMF50115R00FHEB replace RNF14FTC115R in my circuit?

A: Yes. Both components share identical electrical specifications: 115 Ohm resistance, ±1% tolerance, 0.25W power rating, and ±50ppm/°C temperature coefficient. Both are metal film axial resistors with flame retardant coating and meet ROHS3 compliance. Physical dimensions vary slightly, but both fit standard through-hole PCB layouts.

Q: What is the difference in operating temperature range?

A: The RNF14FTC115R operates from -55°C to 155°C, while the CMF50115R00FHEB extends to 175°C. For applications within the -55°C to 155°C range, both parts perform identically. Applications requiring operation above 155°C require the CMF50115R00FHEB.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats are supply and assembly convenience options only. They do not affect component electrical characteristics or performance.

Q: Are both parts RoHS compliant?

A: Yes. Both RNF14FTC115R and CMF50115R00FHEB are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What additional feature does the CMF50115R00FHEB provide?

A: The CMF50115R00FHEB includes moisture-resistant construction in addition to flame retardant coating, providing enhanced protection in humid or moisture-prone environments.
