Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC232R is determined by the following critical parameters: resistance value (232 Ohms), tolerance (±1%), composition (metal film), package type (axial), and compliance certifications (ROHS3). The identified substitute parts maintain these core electrical and mechanical specifications.

CMF55232R00FHEB qualifies as an upgrade substitute with increased power rating (0.5W vs. 0.25W) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C), while preserving all other critical parameters.

CMF50232R00FHEB qualifies as a direct equivalent substitute with identical power rating (0.25W) and extended operating temperature range (-55°C ~ 175°C), maintaining all other electrical specifications.

Both substitute parts are manufactured by Vishay Dale, feature moisture-resistant construction in addition to flame retardant coating, and maintain ROHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Selection between the main part and substitutes depends on application requirements and environmental constraints:

The RNF14FTC232R remains the primary choice for applications with operating temperatures not exceeding 155°C and where the 0.25W power rating is sufficient. All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across industrial and commercial applications.

CMF50232R00FHEB is recommended as a direct equivalent substitute when the RNF14FTC232R is unavailable. This part maintains identical electrical specifications and power rating while providing extended operating temperature capability to 175°C and moisture-resistant construction. Physical dimensions are smaller, which may require PCB layout verification.

CMF55232R00FHEB is recommended when applications require higher power dissipation capability (0.5W vs. 0.25W) or extended temperature operation to 175°C. The increased power rating provides design margin for thermal stress conditions. Physical dimensions are comparable to the main part, minimizing layout impact.

Frequently Asked Questions (FAQ)

Q: Can CMF50232R00FHEB be used as a direct replacement for RNF14FTC232R?

A: Yes. Both parts share identical resistance (232 Ohms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±50ppm/°C), and package type (axial). CMF50232R00FHEB provides extended operating temperature range (-55°C ~ 175°C) and moisture-resistant construction. Physical dimensions differ; verify PCB layout compatibility before substitution.

Q: What is the difference between CMF55232R00FHEB and CMF50232R00FHEB?

A: Both parts are manufactured by Vishay Dale with identical resistance, tolerance, composition, and temperature coefficient. The primary difference is power rating: CMF55232R00FHEB is rated 0.5W (1/2W) while CMF50232R00FHEB is rated 0.25W (1/4W). Both support extended operating temperature to 175°C. Physical dimensions differ between the two parts.

Q: Are all three parts ROHS3 compliant?

A: Yes. RNF14FTC232R, CMF55232R00FHEB, and CMF50232R00FHEB are all ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications.

Q: Does the smaller physical size of CMF50232R00FHEB affect electrical performance?

A: No. Physical size does not affect electrical performance. All three parts maintain identical resistance value, tolerance, temperature coefficient, and composition. Smaller dimensions may require PCB layout verification to ensure proper spacing and thermal management.

Q: Can CMF55232R00FHEB be used in place of RNF14FTC232R in all applications?

A: CMF55232R00FHEB is electrically compatible with RNF14FTC232R for all specifications except power rating (0.5W vs. 0.25W) and operating temperature range (175°C vs. 155°C maximum). The higher power rating provides additional thermal margin. Physical dimensions are comparable. Verify application requirements before substitution.
