Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC196R is determined by the following critical parameters:

• Resistance value: 196 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)

The identified substitute parts maintain these core electrical specifications. Variations in power rating (0.5W vs. 0.25W), operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C), physical dimensions, and packaging format (Cut Tape vs. Tape & Reel) are permitted within the substitution framework, provided the application circuit design accommodates these differences.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original component.

CMF50196R00FHEB is the manufacturer-recommended substitute, offering identical power rating (0.25W) and package type (Axial) to the RNF14FTC196R. This part provides direct functional equivalence with extended operating temperature range (-55°C ~ 175°C) and moisture-resistant construction. REACH status is listed as Affected for this part number.

CMF55196R00FHEB provides an upgrade path with increased power dissipation capability (0.5W vs. 0.25W) while maintaining all other critical electrical parameters. This option accommodates applications requiring higher thermal margin or increased power handling. REACH status is listed as Unaffected for this part number.

Both Vishay Dale alternatives feature moisture-resistant construction, providing enhanced environmental protection compared to the original Stackpole component.

Frequently Asked Questions (FAQ)

Q: Can CMF55196R00FHEB replace RNF14FTC196R in any application?

A: CMF55196R00FHEB maintains identical resistance (196 Ohms), tolerance (±1%), composition (Metal Film), and temperature coefficient (±50ppm/°C). The increased power rating (0.5W vs. 0.25W) and extended operating temperature range (-55°C ~ 175°C) make it suitable for applications where the original 0.25W rating is adequate. Physical dimensions differ slightly; verify PCB layout compatibility.

Q: What is the difference between CMF55196R00FHEB and CMF50196R00FHEB?

A: Both parts share identical electrical specifications (196 Ohms ±1%, ±50ppm/°C, Metal Film). CMF55196R00FHEB is rated at 0.5W (1/2W) with dimensions 0.090" Dia x 0.240" L, while CMF50196R00FHEB is rated at 0.25W (1/4W) with dimensions 0.065" Dia x 0.150" L. Select based on circuit power dissipation requirements and available PCB space.

Q: Are packaging format differences significant?

A: The main part is supplied in Tape & Reel (TR) format, while both substitutes are supplied in Cut Tape (CT) format. This affects procurement and assembly processes but does not impact electrical or mechanical performance of the component itself.

Q: Do the substitute parts maintain the same safety and flame retardant properties?

A: Both CMF55196R00FHEB and CMF50196R00FHEB include flame retardant coating and safety construction. Additionally, both feature moisture-resistant construction, providing enhanced environmental protection beyond the original RNF14FTC196R specification.

Q: What is the significance of REACH status differences?

A: CMF50196R00FHEB is listed as REACH Affected, while CMF55196R00FHEB is listed as REACH Unaffected. Verify compliance requirements for your specific application and regulatory jurisdiction before final component selection.
