Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC5K36 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Substitution Criteria:

• Resistance value: 5.36 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Package Type: Axial (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Allowable Variations:

• Power Rating: May be equal or higher than 0.25W
• Operating Temperature Range: May be equal or wider than -55°C ~ 155°C
• Physical Dimensions: May vary within axial package constraints
• Packaging Format: May differ (Tape & Reel vs. Cut Tape)
• Manufacturer: Different manufacturers acceptable if all electrical parameters match

The two identified substitutes meet all primary criteria while offering enhanced specifications in power rating and/or operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical compatibility with the RNF14FTC5K36 across all critical parameters. Selection between alternatives depends on application-specific requirements:

CMF555K3600FHEB (Upgrade Option): This substitute provides enhanced power dissipation capability at 0.5W (1/2W) and extended operating temperature range to 175°C. The Vishay Dale CMF series includes moisture-resistant construction, offering improved environmental protection. Physical dimensions are comparable to the main part. This option is suitable for applications requiring higher thermal headroom or extended temperature operation.

CMF505K3600FHEB (MFR Recommended Option): This substitute maintains the identical 0.25W power rating and provides the same electrical performance as the main part. The Vishay Dale CMF series construction includes moisture-resistant features and extended operating temperature range to 175°C. Physical dimensions are reduced compared to the main part. This option provides direct functional equivalence with enhanced environmental protection and wider temperature capability.

Both substitutes are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the main part. All three components are currently in active production status with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CMF555K3600FHEB be used as a direct replacement for RNF14FTC5K36?

A: Yes. The CMF555K3600FHEB maintains identical electrical specifications (5.36 kOhms, ±1%, ±50ppm/°C, metal film composition) and axial package type. The higher power rating (0.5W vs. 0.25W) and extended temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C) represent enhanced capabilities that do not compromise compatibility. Physical dimensions are similar, allowing use in equivalent PCB layouts.

Q: Can CMF505K3600FHEB be used as a direct replacement for RNF14FTC5K36?

A: Yes. The CMF505K3600FHEB provides identical electrical specifications and power rating (0.25W) to the main part. All critical parameters match exactly. The reduced physical dimensions (0.065" Dia x 0.150" L vs. 0.093" Dia x 0.250" L) may require PCB layout verification to confirm adequate spacing and component clearance.

Q: What are the key differences between the two substitute options?

A: CMF555K3600FHEB offers higher power dissipation (0.5W) and is suitable for applications with greater thermal demands. CMF505K3600FHEB matches the original power rating (0.25W) exactly and features smaller physical dimensions. Both provide extended operating temperature range and moisture-resistant construction compared to the main part.

Q: Are there any packaging format differences between these parts?

A: The main part RNF14FTC5K36 is supplied in Tape & Reel (TR) format. CMF555K3600FHEB and CMF505K3600FHEB are supplied in Cut Tape (CT) format. Both packaging formats are standard for through-hole axial resistors and do not affect component functionality or PCB assembly compatibility.

Q: Do all three parts meet the same regulatory compliance standards?

A: Yes. RNF14FTC5K36, CMF555K3600FHEB, and CMF505K3600FHEB are all ROHS3 compliant and REACH unaffected. All three components meet equivalent regulatory requirements for industrial and commercial applications.
