Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC475R is determined by strict equivalence across the following parameters:

• Resistance value: 475 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification (exact match required)

The CMF55475R00FHEB from Vishay Dale meets all substitution criteria. This part maintains identical electrical specifications while offering enhanced moisture resistance and extended operating temperature range to 175°C.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC475R and CMF55475R00FHEB maintain Active product status and full ROHS3 compliance with EAR99 classification. Selection between these parts should be based on:

Stackpole RNF12FTC475R: Primary selection when Tape & Reel packaging is required for automated assembly processes or when the larger physical envelope (2.75mm diameter) is specified in board layout.

Vishay Dale CMF55475R00FHEB: Suitable alternative when Cut Tape packaging is acceptable, when compact form factor (2.29mm diameter) is preferred, or when extended operating temperature capability to 175°C is required. The addition of moisture resistance provides enhanced environmental protection.

Both parts satisfy identical electrical and regulatory requirements for direct substitution in 475 Ohm ±1% 0.5W metal film resistor applications.

Frequently Asked Questions (FAQ)

Q: Can CMF55475R00FHEB replace RNF12FTC475R in existing designs?

A: Yes. Both parts are electrically equivalent with identical resistance, tolerance, power rating, and temperature coefficient. Physical dimensions differ slightly; verify board layout accommodates the CMF55 envelope (2.29mm diameter vs. 2.75mm diameter).

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

A: RNF12FTC475R is supplied in Tape & Reel format suitable for pick-and-place assembly. CMF55475R00FHEB is supplied in Cut Tape format. Packaging selection depends on assembly process requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both RNF12FTC475R and CMF55475R00FHEB are ROHS3 Compliant and REACH Unaffected.

Q: What is the temperature operating range difference?

A: RNF12FTC475R operates from -55°C to 155°C. CMF55475R00FHEB extends to -55°C to 175°C. Both ranges cover standard industrial applications; the Vishay part provides additional thermal margin.

Q: Does the moisture resistance feature of CMF55475R00FHEB affect compatibility?

A: No. Moisture resistance is an additional feature that does not impact electrical performance or substitution compatibility. It provides enhanced reliability in humid environments.
