• Power rating of 0.5W (1/2W)
• Metal film composition
• Temperature coefficient of ±50ppm/°C
• Axial package configuration
• ROHS3 compliance
• Flame retardant coating and safety features

The CMF55412R00FHEB from Vishay Dale meets all these core electrical and mechanical requirements, enabling direct substitution in applications where the RNF12FTC412R is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC412R and CMF55412R00FHEB are Active status components with ROHS3 compliance and REACH unaffected designation. The CMF55412R00FHEB provides an extended operating temperature range to 175°C compared to 155°C for the RNF12FTC412R, and includes moisture resistant properties in addition to flame retardant coating. Physical dimensions differ, with the CMF55 series offering a more compact form factor. Selection between these parts should be based on specific application requirements regarding temperature range, physical space constraints, and packaging format needs (Tape & Reel versus Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can the CMF55412R00FHEB directly replace the RNF12FTC412R in all applications?

A: The CMF55412R00FHEB meets all core electrical specifications (412 Ohms ±1%, 0.5W, ±50ppm/°C, metal film composition). Physical dimensions differ, so PCB layout and mechanical clearance must be verified. The extended temperature range of the CMF55 series provides additional operational margin.

Q: What is the difference in packaging between these parts?

A: The RNF12FTC412R is supplied in Tape & Reel (TR) format, while the CMF55412R00FHEB is supplied in Cut Tape (CT) format. This affects handling, storage, and automated assembly processes but does not impact electrical performance.

Q: Are both parts suitable for high-temperature applications?

A: The RNF12FTC412R operates to 155°C, while the CMF55412R00FHEB operates to 175°C. For applications requiring operation above 155°C, the CMF55 series is the appropriate selection.

Q: Do both parts meet environmental compliance requirements?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What additional features does the CMF55412R00FHEB provide?

A: The CMF55412R00FHEB includes moisture resistant properties in addition to flame retardant coating, providing enhanced environmental protection compared to the RNF12FTC412R.
