Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC11R5 are qualified based on the following criteria:

Electrical Equivalence: Resistance value (11.5 Ohms), tolerance (±1%), and temperature coefficient (±50ppm/°C) must be identical.

Mechanical Compatibility: Package type must be axial through-hole configuration with compatible lead terminations (2 terminations).

Composition & Features: Metal film construction with flame retardant coating and safety features must be maintained.

Compliance & Certifications: RoHS3 compliance and REACH unaffected status must be preserved.

Power Rating Consideration: Substitute parts may have equal or higher power ratings, as this does not compromise circuit performance in applications designed for the original 0.25W specification.

Parameter Comparison

Engineering Selection Recommendations

The CMF5511R500FHEB qualifies as a direct substitute for the RNF14FTC11R5 based on electrical and mechanical equivalence. Both parts maintain identical resistance, tolerance, and temperature coefficient specifications. The substitute part offers a higher power rating (0.5W versus 0.25W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C), providing additional thermal margin in applications. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The CMF5511R500FHEB includes moisture-resistant features in addition to flame retardant coating, enhancing environmental protection. Physical dimensions are comparable between both axial packages, supporting direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can the CMF5511R500FHEB replace the RNF14FTC11R5 in existing designs?

A: Yes. Both parts share identical electrical specifications (11.5 Ohms ±1%, ±50ppm/°C temperature coefficient) and axial package configuration. The substitute part's higher power rating and extended temperature range do not create compatibility issues in circuits designed for the original part.

Q: What is the significance of the higher power rating on the substitute part?

A: The CMF5511R500FHEB is rated for 0.5W compared to the RNF14FTC11R5 at 0.25W. This provides additional thermal headroom and does not affect circuit operation. The part will function correctly in applications designed for 0.25W specifications.

Q: Are there packaging differences between these parts?

A: Both parts use axial through-hole packages with 2 terminations. Physical dimensions are comparable (RNF14FTC11R5: 0.093" Dia x 0.250" L; CMF5511R500FHEB: 0.090" Dia x 0.240" L), supporting direct board-level substitution. The main part uses Tape & Reel packaging while the substitute uses Cut Tape packaging.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RNF14FTC11R5 and CMF5511R500FHEB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What additional features does the substitute part provide?

A: The CMF5511R500FHEB includes moisture-resistant properties in addition to flame retardant coating, offering enhanced environmental protection compared to the main part.
