Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC698R is determined by strict adherence to the following electrical and mechanical parameters:

Core Substitution Criteria:

• Resistance value: 698 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Package Type: Axial (exact match required)
• RoHS Status: ROHS3 Compliant (minimum requirement)

Allowable Variations:

• Power Rating: May be equal to or greater than 0.25W
• Operating Temperature Range: May extend beyond -55°C ~ 155°C
• Physical Dimensions: May vary within axial package constraints
• Packaging Format: Cut Tape (CT) acceptable as alternative to Tape & Reel (TR)
• Manufacturer: Alternative qualified manufacturers permitted

The identified substitute parts CMF55698R00FHEB and CMF50698R00FHEB satisfy all core criteria while offering enhanced thermal performance and moisture resistance features.

Parameter Comparison

Engineering Selection Recommendations

CMF50698R00FHEB (MFR Recommended): This substitute maintains identical power rating (0.25W) and physical form factor to the RNF14FTC698R while providing extended operating temperature range (-55°C ~ 175°C) and moisture resistance. All electrical parameters remain equivalent. This part is designated as manufacturer recommended and represents the closest functional equivalent with enhanced environmental protection.

CMF55698R00FHEB (Upgrade): This substitute doubles the power rating to 0.5W (1/2W), providing increased thermal margin for applications subject to higher dissipation or thermal stress. Operating temperature range extends to 175°C. Selection of this upgrade is appropriate when circuit design permits the larger physical footprint or when enhanced thermal performance is required. All core electrical specifications remain identical to the main part.

Both substitute parts maintain ROHS3 compliance, Active product status, and are manufactured by Vishay Dale, an established qualified supplier. Selection between substitutes depends on application thermal requirements and available board space.

Frequently Asked Questions (FAQ)

Q: Can CMF55698R00FHEB be used as a direct replacement for RNF14FTC698R?

A: Yes. The CMF55698R00FHEB maintains all core electrical parameters (698 Ohms, ±1%, ±50ppm/°C, metal film composition). The increased power rating (0.5W vs 0.25W) and extended temperature range represent performance enhancements. Physical dimensions differ slightly; verify PCB layout accommodates the 0.090" diameter vs 0.093" diameter specification.

Q: What is the difference between CMF55698R00FHEB and CMF50698R00FHEB?

A: Both parts share identical electrical specifications. CMF55698R00FHEB is rated at 0.5W (1/2W) with dimensions 0.090" Dia x 0.240" L. CMF50698R00FHEB is rated at 0.25W (1/4W) with dimensions 0.065" Dia x 0.150" L. CMF50698R00FHEB provides closer dimensional matching to the original part and is designated as manufacturer recommended.

Q: Are packaging format differences (Tape & Reel vs Cut Tape) significant for substitution?

A: Packaging format affects handling and assembly processes but does not impact electrical or mechanical compatibility. Tape & Reel (TR) is optimized for automated assembly; Cut Tape (CT) is suitable for manual or lower-volume assembly. Verify your assembly process requirements before selecting based on packaging format.

Q: Do substitute parts maintain the same temperature coefficient?

A: Yes. Both CMF55698R00FHEB and CMF50698R00FHEB maintain ±50ppm/°C temperature coefficient, identical to RNF14FTC698R. This ensures equivalent frequency stability and thermal drift characteristics across the operating temperature range.

Q: What additional features do the Vishay Dale substitutes provide?

A: Both Vishay Dale substitutes add moisture resistance to the flame retardant coating and safety features present in the original part. This enhancement is beneficial for applications exposed to humidity or condensation without introducing incompatibility.
