Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC267R is determined by strict equivalence across the following parameters:

• Resistance value: 267 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Package configuration: Axial through-hole
• Regulatory compliance: ROHS3 Compliant

The CMF55267R00FHEB from Vishay Dale meets all substitution criteria. Both components share identical electrical specifications and axial package geometry, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC267R and CMF55267R00FHEB are active production components with ROHS3 compliance and REACH unaffected status. The CMF55267R00FHEB provides an extended operating temperature range to 175°C and includes moisture resistant properties in addition to flame retardant coating. Physical dimensions differ between the two parts; the CMF55 variant is smaller in both diameter and length. Selection between these components depends on available board space and thermal environment requirements within the specified operating ranges.

Frequently Asked Questions (FAQ)

Q: Can CMF55267R00FHEB replace RNF12FTC267R in all applications?

A: Yes, provided that the smaller physical dimensions of the CMF55 (0.090" Dia x 0.240" L versus 0.108" Dia x 0.344" L) are compatible with the PCB layout. Electrical specifications are equivalent.

Q: What is the significance of the extended temperature range in the CMF55267R00FHEB?

A: The CMF55 operates to 175°C versus 155°C for the RNF12. This extended range provides additional thermal margin in high-temperature applications, though both components meet the same electrical performance criteria within their respective operating ranges.

Q: Are there packaging format differences between these parts?

A: Yes. The RNF12FTC267R is supplied in Tape & Reel (TR) format, while the CMF55267R00FHEB is supplied in Cut Tape (CT) format. This affects procurement and assembly processes but does not impact component functionality.

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 codes.
