Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC562R is determined by the following critical parameters:

• Electrical Equivalence: Resistance value (562 Ohms), tolerance (±1%), and power rating (0.5W) must be identical
• Composition: Metal film construction required for thermal stability and precision
• Temperature Coefficient: ±50ppm/°C specification must be maintained
• Package Configuration: Axial through-hole package mandatory for mechanical compatibility
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required
• Environmental Features: Flame retardant coating and safety designation must be present

The CMF55562R00FHEB from Vishay Dale meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC562R and CMF55562R00FHEB are Active status components with full ROHS3 compliance and REACH unaffected designation. The CMF55562R00FHEB provides an extended operating temperature range to 175°C (versus 155°C for the RNF12FTC562R) and includes moisture resistant features in addition to flame retardant coating. All core electrical parameters—resistance, tolerance, power rating, temperature coefficient, and composition—are identical between both parts. Selection between these components should be based on application-specific requirements regarding maximum operating temperature and packaging format (Tape & Reel versus Cut Tape availability).

Frequently Asked Questions (FAQ)

Q: Can CMF55562R00FHEB replace RNF12FTC562R in all applications?

A: Yes, provided the application does not require the specific packaging format of the original part. The CMF55562R00FHEB is supplied in Cut Tape (CT) format while the RNF12FTC562R is supplied in Tape & Reel (TR) format. Electrical and mechanical specifications are equivalent.

Q: What is the significance of the extended temperature range in the CMF55562R00FHEB?

A: The CMF55562R00FHEB operates to 175°C maximum, compared to 155°C for the RNF12FTC562R. This provides additional thermal margin for applications operating at elevated temperatures. Both components maintain the same ±50ppm/°C temperature coefficient.

Q: Are there dimensional differences between these axial packages?

A: Yes. The RNF12FTC562R measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm). The CMF55562R00FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both are axial configuration, but the CMF55562R00FHEB is physically smaller. Verify PCB layout compatibility before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0090.

Q: What additional feature does the CMF55562R00FHEB provide?

A: The CMF55562R00FHEB includes moisture resistant properties in addition to flame retardant coating, providing enhanced environmental protection compared to the RNF12FTC562R.
