Parameter Comparison

Engineering Selection Recommendations

Both the RNF12FTC36K5 and CMF5536K500FHEB maintain Active product status and full ROHS3 compliance with REACH Unaffected designation, confirming regulatory suitability for current applications. The CMF5536K500FHEB offers an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and includes moisture-resistant features in addition to flame retardant coating. Physical dimensions differ between the two parts, with the CMF5536K500FHEB featuring a smaller profile (0.090" Dia x 0.240" L versus 0.108" Dia x 0.344" L). Selection between these parts should account for PCB layout constraints and thermal environment requirements. The CMF5536K500FHEB provides higher inventory availability at 2722 units compared to 876 units for the RNF12FTC36K5.

Frequently Asked Questions (FAQ)

Q: Can the CMF5536K500FHEB directly replace the RNF12FTC36K5 in existing designs?

A: Yes. Both parts share identical electrical specifications (36.5 kOhms ±1%, 0.5W, ±50ppm/°C) and axial through-hole package configuration. The smaller physical dimensions of the CMF5536K500FHEB may provide layout advantages in space-constrained applications.

Q: What is the significance of the different physical dimensions?

A: The CMF5536K500FHEB is physically smaller (0.090" Dia x 0.240" L) compared to the RNF12FTC36K5 (0.108" Dia x 0.344" L). Both fit standard axial through-hole footprints, but the smaller profile may reduce PCB real estate requirements and improve thermal dissipation in dense layouts.

Q: Are there differences in operating temperature ranges?

A: The CMF5536K500FHEB operates across -55°C ~ 175°C, providing a 20°C higher upper limit than the RNF12FTC36K5 (-55°C ~ 155°C). For applications operating near the upper temperature boundary, the CMF5536K500FHEB offers extended thermal margin.

Q: What packaging formats are available?

A: The RNF12FTC36K5 is supplied in Tape & Reel (TR) format, while the CMF5536K500FHEB is available in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and volume considerations.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the RNF12FTC36K5 and CMF5536K500FHEB are ROHS3 Compliant and REACH Unaffected, confirming compliance with current environmental and safety regulations.

Q: What additional features does the CMF5536K500FHEB provide?

A: The CMF5536K500FHEB includes moisture-resistant properties in addition to flame retardant coating, offering enhanced protection in humid or moisture-prone environments compared to the RNF12FTC36K5.
