Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC36R5 are qualified based on the following criteria:

• Identical resistance value: 36.5 Ohms
• Matching tolerance: ±1%
• Equivalent or superior power rating: 0.25W minimum
• Identical composition: Metal Film
• Matching temperature coefficient: ±50ppm/°C
• Compatible package type: Axial through-hole
• Equivalent or superior operating temperature range
• Matching safety and flame retardant features
• ROHS3 compliance maintained

The CMF5536R500FHEB qualifies as a substitute due to matching electrical specifications and enhanced power rating (0.5W vs 0.25W), providing additional thermal margin while maintaining all critical electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the RNF14FTC36R5 and CMF5536R500FHEB maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The CMF5536R500FHEB provides enhanced thermal performance through its 0.5W power rating and extended operating temperature range to 175°C, while maintaining identical electrical specifications. Physical dimensions are comparable, with the substitute part slightly smaller in diameter and length. Both parts are active products with established supply chains. Selection between these parts should be based on application thermal requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can CMF5536R500FHEB directly replace RNF14FTC36R5 in existing designs?

A: Yes. Both parts share identical resistance (36.5 Ohms), tolerance (±1%), temperature coefficient (±50ppm/°C), and axial package configuration. The substitute part's higher power rating (0.5W vs 0.25W) and extended temperature range provide additional design margin without affecting electrical performance.

Q: What are the physical compatibility considerations?

A: The CMF5536R500FHEB is slightly smaller (0.090" Dia x 0.240" L) compared to the RNF14FTC36R5 (0.093" Dia x 0.250" L). Both are axial through-hole components with 2 terminations, suitable for standard PCB layouts. The dimensional difference is negligible for most applications.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution in regulated applications.

Q: What is the significance of the moisture resistant feature in the substitute part?

A: The CMF5536R500FHEB includes moisture resistant construction in addition to flame retardant coating. This provides enhanced environmental protection in humid or moisture-prone applications, though both parts maintain equivalent safety ratings.

Q: How do the operating temperature ranges differ?

A: The RNF14FTC36R5 operates from -55°C to 155°C, while the CMF5536R500FHEB extends to 175°C. The substitute part accommodates higher temperature environments while maintaining the same temperature coefficient specification.
