Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC16K5 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 16.5 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Temperature Coefficient: ±50ppm/°C

Mechanical Parameters (Must Match):

• Package type: Axial through-hole
• Number of terminations: 2

Allowable Variations:

• Power rating: Equal or greater than 0.25W
• Operating temperature range: Equal or greater than -55°C ~ 155°C
• Features: Flame retardant coating and safety construction required

Compliance Requirements:

• RoHS3 Compliant status maintained
• REACH Unaffected status maintained

Two substitute parts meet these criteria: CMF5516K500FHEB (0.5W upgrade) and CMF5016K500FHEB (direct 0.25W equivalent).

Parameter Comparison

Engineering Selection Recommendations

CMF5016K500FHEB (Direct Equivalent): This part is the manufacturer-recommended substitute. It maintains identical electrical specifications (16.5 kOhms, ±1%, 0.25W, ±50ppm/°C) and package type (Axial). The operating temperature range extends to 175°C, providing enhanced thermal performance. Additional moisture resistance features are included. Physical dimensions are smaller. RoHS3 compliance is confirmed. This part is suitable for direct replacement in applications where the original RNF14FTC16K5 is specified.

CMF5516K500FHEB (Upgrade Substitute): This part provides identical electrical specifications with an increased power rating of 0.5W (1/2W), double the original 0.25W rating. Operating temperature range extends to 175°C. Moisture resistance features are included. Physical dimensions are comparable to the original part. This part is suitable for applications where increased power dissipation capability is beneficial or where thermal margin is required. RoHS3 compliance status is not specified in the provided data.

Both substitute parts maintain REACH Unaffected status and EAR99 ECCN classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can CMF5016K500FHEB be used as a direct replacement for RNF14FTC16K5?

A: Yes. Both parts share identical resistance (16.5 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), and temperature coefficient (±50ppm/°C). The CMF5016K500FHEB is the manufacturer-recommended equivalent. Physical dimensions differ slightly, but both are axial through-hole packages with 2 terminations suitable for standard PCB layouts.

Q: What is the difference between CMF5016K500FHEB and CMF5516K500FHEB?

A: The primary difference is power rating. CMF5016K500FHEB is rated at 0.25W (1/4W), matching the original part. CMF5516K500FHEB is rated at 0.5W (1/2W), providing double the power dissipation capability. Both maintain identical resistance, tolerance, and temperature coefficient values. Physical dimensions are slightly different due to the higher power rating.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: All three parts use axial through-hole packaging with 2 terminations. Physical dimensions vary slightly: RNF14FTC16K5 measures 0.093" Dia x 0.250" L, CMF5016K500FHEB measures 0.065" Dia x 0.150" L, and CMF5516K500FHEB measures 0.090" Dia x 0.240" L. These dimensional differences may affect PCB layout spacing and component density. Verify PCB hole spacing and clearance requirements before substitution.

Q: Do the substitute parts maintain the same compliance certifications?

A: CMF5016K500FHEB is confirmed ROHS3 Compliant and REACH Unaffected. CMF5516K500FHEB compliance status is not specified in the provided data. Both parts maintain EAR99 ECCN classification. Verify specific compliance requirements for your application before final selection.

Q: What is the advantage of the extended operating temperature range in the substitute parts?

A: Both Vishay Dale substitutes operate to 175°C, compared to 155°C for the original RNF14FTC16K5. This extended range provides additional thermal margin in high-temperature applications and may improve long-term reliability in thermally demanding environments.
