Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC365R is determined by the following core parameters: resistance value (365 Ohms), tolerance (±1%), composition (metal film), and package type (axial). All identified substitutes maintain these electrical specifications.

Two substitute categories are defined:

MFR Recommended Substitute (Direct Replacement): CMF50365R00FHEB maintains identical power rating (0.25W), resistance, tolerance, and temperature coefficient. This substitute is functionally equivalent with enhanced moisture resistance and extended operating temperature range (-55°C ~ 175°C).

Upgrade Substitute (Higher Power Rating): CMF55365R00FHEB provides increased power dissipation capability (0.5W) while maintaining all other core electrical parameters. This substitute accommodates applications requiring higher thermal headroom.

Parameter Comparison

Engineering Selection Recommendations

CMF50365R00FHEB Selection: This MFR recommended substitute is the primary choice for direct replacement applications. It maintains identical electrical performance and power rating while providing enhanced moisture resistance and extended operating temperature capability to 175°C. All parts are Active status and ROHS3 compliant. This substitute is suitable for applications where the original part is unavailable or where extended temperature operation is beneficial.

CMF55365R00FHEB Selection: This upgrade substitute is appropriate for applications where thermal margin is a design consideration. The increased 0.5W power rating provides additional dissipation capacity while maintaining all other electrical specifications. Physical dimensions are slightly larger; PCB layout verification is necessary prior to implementation. This substitute is suitable for high-reliability applications or environments with elevated ambient temperatures.

Frequently Asked Questions (FAQ)

Q: Can CMF50365R00FHEB be used as a direct replacement for RNF14FTC365R?

A: Yes. CMF50365R00FHEB maintains identical resistance (365 Ohms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±50ppm/°C). The extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and enhanced moisture resistance provide additional performance margin. Packaging format differs (Cut Tape versus Tape & Reel); assembly process compatibility should be confirmed.

Q: What is the primary difference between the two substitute options?

A: CMF50365R00FHEB provides direct electrical equivalence with enhanced environmental protection. CMF55365R00FHEB increases power dissipation capability from 0.25W to 0.5W, suitable for applications requiring higher thermal headroom. Both maintain identical resistance and tolerance specifications.

Q: Are physical dimensions compatible between the main part and substitutes?

A: All three parts use axial package configuration. RNF14FTC365R dimensions are 0.093" Dia x 0.250" L. CMF50365R00FHEB dimensions are 0.065" Dia x 0.150" L (smaller). CMF55365R00FHEB dimensions are 0.090" Dia x 0.240" L (similar to main part). PCB layout and mechanical clearance should be verified for each substitute selection.

Q: Do all parts meet current compliance requirements?

A: Yes. RNF14FTC365R, CMF50365R00FHEB, and CMF55365R00FHEB are all ROHS3 compliant and REACH unaffected. All parts are Active status.
