Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF12FTC698R is determined by the following critical parameters:

Resistance value must be 698 Ohms with ±1% tolerance to ensure circuit performance specifications are maintained. Power rating must be 0.5W minimum to support thermal requirements. Composition must be metal film to preserve frequency response and stability characteristics. Package configuration must be axial through-hole to ensure mechanical compatibility with PCB layouts and assembly processes. Temperature coefficient of ±50ppm/°C establishes the thermal stability requirement. Operating temperature range must support the application's minimum requirement of -55°C to 155°C. RoHS3 compliance and REACH unaffected status are mandatory for regulatory alignment.

The CMF55698R00FHEB from Vishay Dale meets all substitution criteria while offering extended operating temperature range to 175°C and moisture-resistant construction as additional features.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC698R and CMF55698R00FHEB are Active status components with full ROHS3 compliance and REACH unaffected certification, qualifying them for equivalent circuit applications. Selection between these parts should be based on packaging format availability and physical space constraints. The Stackpole RNF12FTC698R is supplied in Tape & Reel format suitable for high-volume automated assembly. The Vishay Dale CMF55698R00FHEB is supplied in Cut Tape format and features a smaller physical profile (0.090" diameter vs. 0.108" diameter) with extended operating temperature capability to 175°C, providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can CMF55698R00FHEB replace RNF12FTC698R in all applications?

A: Yes, provided the physical dimensions are compatible with the PCB layout. The CMF55698R00FHEB has a smaller diameter (0.090" vs. 0.108") and shorter length (0.240" vs. 0.344"), which may require PCB pad spacing verification. All electrical parameters, tolerance, power rating, and temperature coefficient are identical.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is optimized for high-volume automated pick-and-place assembly operations. Cut Tape packaging is supplied as individual components on carrier tape, suitable for lower-volume or manual assembly processes. Both formats contain the same component.

Q: Does the extended temperature range of CMF55698R00FHEB affect circuit performance?

A: The extended operating range to 175°C does not affect performance within the standard operating range of -55°C to 155°C. The temperature coefficient remains ±50ppm/°C for both parts, ensuring equivalent frequency stability and drift characteristics.

Q: Are moisture-resistant features of CMF55698R00FHEB required for substitution?

A: Moisture resistance is an additional feature of the CMF55698R00FHEB and is not required for substitution compatibility. Both parts are suitable for standard industrial environments. Moisture resistance provides enhanced reliability in high-humidity applications.

Q: What compliance certifications apply to both parts?

A: Both RNF12FTC698R and CMF55698R00FHEB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in EU and global markets.
