Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC464R is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 464 Ohms (exact match required)
• Tolerance: ±1% (matching precision grade)
• Power rating: 0.5W minimum (1/2W)
• Temperature coefficient: ±50ppm/°C or better
• Composition: Metal film construction

Mechanical Compatibility Requirements:

• Package: Axial through-hole configuration
• Number of terminations: 2-pin
• Physical form factor: Compatible with standard PCB axial component footprints

Regulatory & Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status
• Flame retardant coating and safety features required

The CMF55464R00FHEB from Vishay Dale meets all substitution criteria while maintaining full electrical and mechanical compatibility with the RNF12FTC464R.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC464R and CMF55464R00FHEB are Active status components meeting ROHS3 and REACH compliance requirements. The CMF55464R00FHEB provides an extended operating temperature range to 175°C compared to 155°C for the RNF12FTC464R, and includes moisture-resistant properties in addition to flame retardant coating. Selection between these parts should be based on application temperature requirements and packaging format availability. The RNF12FTC464R is supplied in Tape & Reel format, while the CMF55464R00FHEB is available in Cut Tape format.

Frequently Asked Questions (FAQ)

Q: Can the CMF55464R00FHEB directly replace the RNF12FTC464R in existing designs?

A: Yes. Both components share identical electrical specifications (464 Ohms ±1%, 0.5W, ±50ppm/°C), metal film composition, and axial package configuration. Both meet ROHS3 compliance and feature flame retardant, safety-grade construction. The CMF55464R00FHEB offers extended temperature range and moisture resistance as additional benefits.

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

A: The RNF12FTC464R measures 0.108" diameter × 0.344" length (2.75mm × 8.75mm). The CMF55464R00FHEB measures 0.090" diameter × 0.240" length (2.29mm × 6.10mm). Both are axial through-hole components compatible with standard PCB footprints, though the Vishay part is more compact.

Q: Are there packaging format differences?

A: Yes. The RNF12FTC464R is supplied in Tape & Reel (TR) format, while the CMF55464R00FHEB is supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and volume needs.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected. Both feature flame retardant coating and safety-grade construction suitable for equivalent applications.

Q: What is the temperature coefficient specification and why does it matter?

A: Both parts specify ±50ppm/°C temperature coefficient, meaning resistance value changes by a maximum of 50 parts per million for each degree Celsius change in operating temperature. This specification ensures stable performance across the operating temperature range and is critical for precision circuit applications.
