Key Parameters

Substitute Part Grouping Explanation

Substitution for the RNF14BTC200R is determined by strict equivalence in the following electrical parameters: resistance value (200 Ohms), tolerance grade (±0.1%), composition (metal film), and temperature coefficient (±50ppm/°C). The substitute part CMF55200R00BHEB maintains all these core electrical specifications. Mechanical compatibility is confirmed through axial package type equivalence. Power rating may be equal or higher without affecting substitution validity, as a higher-rated component can safely operate in applications designed for lower power dissipation. Operating temperature range may be extended without compromising substitution. Both parts maintain identical RoHS3 compliance and REACH Unaffected status, ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

The CMF55200R00BHEB qualifies as a direct substitute for the RNF14BTC200R based on electrical parameter equivalence and regulatory compliance alignment. Both parts are Active in product status and maintain identical RoHS3 and REACH compliance certifications. 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 design margin without introducing incompatibility. Axial package equivalence and mechanically compatible dimensions support direct board-level substitution. Selection between these parts depends on application-specific requirements for power dissipation and thermal environment rather than electrical or regulatory constraints.

Frequently Asked Questions (FAQ)

Q: Can CMF55200R00BHEB replace RNF14BTC200R in all applications? A: Yes, provided the application does not require the specific physical dimensions or packaging format of the original part. Both components share identical electrical specifications (200 Ohms, ±0.1%, metal film, ±50ppm/°C) and regulatory compliance. The substitute's higher power rating and extended temperature range do not create incompatibility.

Q: What is the significance of the higher power rating on the substitute part? A: The CMF55200R00BHEB is rated for 0.5W compared to the RNF14BTC200R's 0.25W. This means the substitute can safely dissipate more power without exceeding its thermal limits. In applications where the original 0.25W part operates within its power budget, the 0.5W substitute will operate at lower internal temperatures, potentially improving reliability and lifespan.

Q: Are there dimensional differences that affect PCB layout? A: The substitute part (0.090" Dia x 0.240" L) is slightly smaller than the main part (0.093" Dia x 0.250" L). Both maintain axial package compatibility. The smaller dimensions of the substitute may provide minor layout advantages but do not prevent direct substitution on existing PCB designs.

Q: Do both parts meet the same regulatory requirements? A: Yes. Both RNF14BTC200R and CMF55200R00BHEB are ROHS3 Compliant and REACH Unaffected, ensuring equivalent regulatory status for applications requiring these certifications.

Q: What is the difference in operating temperature ranges? A: The RNF14BTC200R operates from -55°C to 155°C, while the CMF55200R00BHEB operates from -55°C to 175°C. The substitute's extended upper temperature limit provides additional thermal margin for high-temperature applications without affecting performance in standard operating conditions.
