Key Parameters

Substitute Part Grouping Explanation

Substitution for the RNF14FTC698K is determined by the following criteria:

• Resistance value: 698 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)
• Power Rating: Equal to or greater than 0.25W
• Operating Temperature Range: Must encompass or exceed -55°C ~ 155°C
• Compliance: ROHS3 compliant (maintained)

The CMF55698K00FHEB from Vishay Dale meets all substitution criteria with a higher power rating (0.5W) and extended upper operating temperature limit (175°C), providing enhanced thermal performance while maintaining all critical electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The CMF55698K00FHEB is a direct substitute for the RNF14FTC698K based on Active product status and ROHS3 compliance maintained across both components. The substitute part provides increased power dissipation capability (0.5W versus 0.25W) and extended maximum operating temperature (175°C versus 155°C), making it suitable for applications requiring higher thermal margins. Both components maintain identical electrical specifications: 698 kOhms resistance, ±1% tolerance, ±50ppm/°C temperature coefficient, and metal film composition. Physical dimensions are comparable within standard axial resistor tolerances. Component selection should be based on application thermal requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can the CMF55698K00FHEB replace the RNF14FTC698K in all applications?

A: Yes, the CMF55698K00FHEB meets all electrical and mechanical substitution criteria. The higher power rating (0.5W) and extended operating temperature range (-55°C ~ 175°C) provide equal or superior performance in all standard circuit applications.

Q: Are there physical compatibility concerns between these axial resistors?

A: Both components use standard axial through-hole packaging. The CMF55698K00FHEB has slightly smaller dimensions (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L), which presents no compatibility issues for PCB mounting or spacing.

Q: Do both parts meet the same compliance standards?

A: Yes, both the RNF14FTC698K and CMF55698K00FHEB are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99.

Q: What is the significance of the ±50ppm/°C temperature coefficient?

A: The temperature coefficient indicates resistance value change per degree Celsius. Both parts maintain identical ±50ppm/°C specifications, ensuring equivalent frequency stability and temperature-dependent performance in precision circuits.

Q: Are packaging formats interchangeable?

A: The RNF14FTC698K is supplied in Tape & Reel (TR) format, while the CMF55698K00FHEB is supplied in Cut Tape (CT) format. Both are standard through-hole axial resistor packaging suitable for automated assembly equipment.
