Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTD294R and CMF55294R00FHEB are active products with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The substitute part CMF55294R00FHEB provides enhanced performance characteristics including higher power dissipation capability (0.5W versus 0.25W), improved temperature coefficient stability (±50ppm/°C versus ±100ppm/°C), and extended maximum operating temperature (175°C versus 155°C). Both parts maintain identical electrical specifications for resistance value and tolerance, ensuring functional equivalence in circuit applications. Selection between these parts depends on application-specific requirements for power dissipation, thermal stability, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CMF55294R00FHEB replace RNF14FTD294R in all applications?

A: Both parts share identical resistance (294 Ohms), tolerance (±1%), composition (metal film), and package type (axial). The substitute part has higher power rating (0.5W versus 0.25W), lower temperature coefficient (±50ppm/°C versus ±100ppm/°C), and wider operating temperature range (-55°C to 175°C versus -55°C to 155°C). Functional replacement is valid where these enhanced specifications do not create design conflicts.

Q: What are the physical dimension differences?

A: RNF14FTD294R measures 0.093" diameter by 0.250" length (2.35mm x 6.35mm). CMF55294R00FHEB measures 0.090" diameter by 0.240" length (2.29mm x 6.10mm). Both are axial package types with 2 terminations. Dimensional differences are minimal and typically accommodate standard PCB through-hole spacing.

Q: Are both parts RoHS compliant?

A: Both RNF14FTD294R and CMF55294R00FHEB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component use.

Q: What is the difference in packaging format?

A: RNF14FTD294R is supplied in Tape & Reel (TR) format, while CMF55294R00FHEB is supplied in Cut Tape (CT) format. This affects procurement and handling procedures but does not impact electrical or mechanical compatibility.

Q: Which part has better temperature stability?

A: CMF55294R00FHEB has a temperature coefficient of ±50ppm/°C compared to RNF14FTD294R at ±100ppm/°C, providing superior stability across temperature variations. CMF55294R00FHEB also supports a higher maximum operating temperature of 175°C versus 155°C.
