Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC562R are identified based on the following critical parameters that determine functional equivalence:

Core Electrical Parameters (Must Match):

• Resistance value: 562 Ohms
• Tolerance: ±1%
• Composition: Metal Film
• Temperature Coefficient: ±50ppm/°C

Mechanical Compatibility:

• Package Type: Axial through-hole configuration

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected status

Two substitute parts meet these criteria with the following distinctions:

CMF50562R00FHEB - Manufacturer Recommended substitute with identical power rating (0.25W) and extended operating temperature range (-55°C ~ 175°C). Identical electrical performance with enhanced thermal capability.

CMF55562R00FHEB - Upgrade substitute with increased power rating (0.5W) and extended operating temperature range (-55°C ~ 175°C). Provides higher power dissipation capability while maintaining identical resistance and tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

CMF50562R00FHEB is the manufacturer-recommended direct substitute. It maintains identical electrical specifications and power rating while providing extended operating temperature capability to 175°C. Both parts are Active status and ROHS3 compliant. The CMF50 series adds moisture resistance features and is available in higher inventory quantities.

CMF55562R00FHEB serves as an upgrade option when higher power dissipation is required in the circuit design. The 0.5W rating provides additional thermal margin compared to the original 0.25W specification. This part maintains all electrical parameters and compliance certifications while offering enhanced reliability in power-dissipation-sensitive applications.

Both substitute parts are suitable for direct replacement in applications where the RNF14FTC562R is specified, provided circuit design parameters do not require the specific lower operating temperature limit of the original part.

Frequently Asked Questions (FAQ)

Q: Can CMF50562R00FHEB be used as a direct replacement for RNF14FTC562R?

A: Yes. Both parts share identical resistance (562 Ohms), tolerance (±1%), power rating (0.25W), temperature coefficient (±50ppm/°C), and axial package configuration. The CMF50 extends the operating temperature range to 175°C and adds moisture resistance. Both are ROHS3 compliant and Active status.

Q: What is the difference between CMF50562R00FHEB and CMF55562R00FHEB?

A: The primary difference is power rating. CMF50 is rated at 0.25W (matching the original part), while CMF55 is rated at 0.5W. Both maintain identical resistance, tolerance, and temperature coefficient. The CMF55 provides higher power dissipation capability for applications requiring additional thermal margin.

Q: Are there packaging differences between these parts?

A: Yes. The RNF14FTC562R is supplied in Tape & Reel (TR) packaging, while both Vishay Dale substitutes (CMF50 and CMF55) are supplied in Cut Tape (CT) packaging. Both are axial through-hole components with compatible mechanical dimensions for circuit board assembly.

Q: Do all parts meet the same compliance requirements?

A: Yes. RNF14FTC562R, CMF50562R00FHEB, and CMF55562R00FHEB are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which substitute should I select for a new design?

A: Selection depends on circuit requirements. Use CMF50562R00FHEB for direct electrical equivalence with extended temperature capability. Use CMF55562R00FHEB if the application requires higher power dissipation or additional thermal margin beyond the 0.25W specification.
