Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC14K7 are qualified based on the following critical parameters:

• Resistance value: 14.7 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)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Substitute parts may vary in power rating and operating temperature range within acceptable engineering limits. The CMF5514K700FHEB offers increased power dissipation capability (0.5W vs. 0.25W), while the CMF5014K700FHEB maintains identical power rating with enhanced moisture resistance. Both substitutes maintain the core electrical and mechanical specifications required for direct replacement in applications where the RNF14FTC14K7 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compliance with ROHS3 and REACH requirements, matching the environmental and regulatory status of the RNF14FTC14K7. The CMF5514K700FHEB provides enhanced thermal performance with a 0.5W power rating and extended operating temperature range to 175°C, suitable for applications requiring higher power dissipation or elevated temperature operation. The CMF5014K700FHEB maintains identical electrical and power specifications while offering moisture-resistant construction and improved dimensional consistency. Selection between substitutes depends on application thermal requirements and environmental exposure conditions. All three parts are active production components with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the CMF5514K700FHEB replace the RNF14FTC14K7 in all applications?

A: The CMF5514K700FHEB is electrically and mechanically compatible with the RNF14FTC14K7 for direct substitution. The increased power rating (0.5W vs. 0.25W) and extended temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C) provide additional operational margin. Physical dimensions differ slightly (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L), which may require verification in space-constrained PCB layouts.

Q: What is the difference between the two Vishay Dale substitutes?

A: The CMF5514K700FHEB is rated at 0.5W (1/2W) with extended temperature capability to 175°C. The CMF5014K700FHEB maintains the 0.25W (1/4W) rating with smaller physical dimensions (0.065" Dia x 0.150" L). Both feature moisture-resistant construction and identical electrical specifications. Selection depends on thermal dissipation requirements and available PCB space.

Q: Are packaging format differences significant for procurement?

A: The RNF14FTC14K7 is supplied in Tape & Reel (TR) format, while both Vishay Dale substitutes are supplied in Cut Tape (CT) format. This affects bulk ordering and automated assembly processes but does not impact component functionality or electrical performance.

Q: Do all parts meet the same compliance standards?

A: Yes. The RNF14FTC14K7, CMF5514K700FHEB, and CMF5014K700FHEB are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
