Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC464R are qualified based on the following critical parameters:

• Resistance value: 464 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The identified substitutes maintain these core electrical and mechanical specifications. Variations in power rating, operating temperature range, and physical dimensions are permitted when the application circuit design accommodates such differences. All substitute parts are manufactured by Vishay Dale under the CMF series and maintain Active product status.

Parameter Comparison

Engineering Selection Recommendations

CMF50464R00FHEB (MFR Recommended): This substitute maintains identical power rating (0.25W) and package dimensions to the RNF14FTC464R while providing extended operating temperature range (-55°C ~ 175°C). The CMF50 series includes moisture-resistant construction and is manufactured by Vishay Dale under Active product status with ROHS3 compliance. This part is recommended for direct replacement in applications where the original specification is maintained.

CMF55464R00FHEB (Upgrade): This substitute provides increased power dissipation capability (0.5W versus 0.25W) while maintaining all other critical electrical parameters. The CMF55 series includes moisture-resistant construction and extended operating temperature range. This part is suitable for applications where thermal margin improvement is beneficial and circuit design accommodates the larger physical dimensions.

Both substitute parts maintain ROHS3 compliance, REACH unaffected status, and Active product status, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CMF50464R00FHEB be used as a direct replacement for RNF14FTC464R?

A: Yes. The CMF50464R00FHEB maintains identical resistance (464 Ohms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±50ppm/°C), and package type (axial). Physical dimensions differ slightly, but both are axial through-hole components suitable for standard PCB mounting.

Q: What is the difference between CMF55464R00FHEB and CMF50464R00FHEB?

A: The primary difference is power rating: CMF55464R00FHEB is rated at 0.5W (1/2W) while CMF50464R00FHEB is rated at 0.25W (1/4W). Both maintain identical resistance, tolerance, and temperature coefficient. The CMF55 variant has larger physical dimensions (0.090" Dia x 0.240" L versus 0.065" Dia x 0.150" L).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The RNF14FTC464R and both substitute parts (CMF55464R00FHEB and CMF50464R00FHEB) are ROHS3 compliant and REACH unaffected.

Q: What operating temperature range should be considered for circuit design?

A: The RNF14FTC464R operates from -55°C to 155°C. Both substitute parts extend this range to -55°C to 175°C. Circuit design should use the most restrictive specification applicable to the application.

Q: Do the substitute parts fit the same PCB footprint?

A: All parts use axial through-hole package type. Physical dimensions vary: RNF14FTC464R is 0.093" Dia x 0.250" L, CMF55464R00FHEB is 0.090" Dia x 0.240" L, and CMF50464R00FHEB is 0.065" Dia x 0.150" L. Standard axial component mounting accommodates these variations.
