Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC200R is determined by the following critical parameters:

• Electrical Specifications: Resistance value (200 Ohms), tolerance (±1%), and power rating (0.5W) must be identical
• Composition & Construction: Metal film composition with flame retardant coating required
• Package Configuration: Axial through-hole package mandatory
• Temperature Performance: Temperature coefficient (±50ppm/°C) and operating range compatibility
• Compliance: RoHS3 compliance and REACH unaffected status required

The CMF55200R00FHEB from Vishay Dale meets all substitution criteria, providing equivalent electrical performance with compatible mechanical and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC200R and CMF55200R00FHEB are Active status components with full RoHS3 compliance and REACH unaffected designation, meeting regulatory requirements for industrial and commercial applications. The CMF55200R00FHEB provides an extended operating temperature range to 175°C compared to 155°C for the RNF12FTC200R, with additional moisture resistance features. Selection between these parts should be based on availability, packaging format preference (Tape & Reel versus Cut Tape), and specific thermal environment requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the CMF55200R00FHEB be used as a direct replacement for the RNF12FTC200R?

A: Yes. Both components share identical electrical specifications (200 Ohms, ±1%, 0.5W), metal film composition, axial package configuration, and temperature coefficient. Mechanical dimensions differ slightly, but both are standard axial through-hole packages suitable for PCB mounting.

Q: What is the difference in physical dimensions between these parts?

A: The RNF12FTC200R measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm). The CMF55200R00FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). The Vishay Dale part is more compact and may be advantageous in space-constrained layouts.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance differentiation exists between these components.

Q: What packaging formats are available?

A: The RNF12FTC200R is supplied in Tape & Reel (TR) format. The CMF55200R00FHEB is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and volume considerations.

Q: Does the extended temperature range of the CMF55200R00FHEB affect substitution suitability?

A: The extended range (-55°C to 175°C versus -55°C to 155°C) represents a capability advantage with no substitution limitation. Applications operating within the RNF12FTC200R range are fully compatible with the CMF55200R00FHEB.
