Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC23K2 are qualified based on the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Resistance value: 23.2 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Package type: Axial
• Temperature coefficient: ±50ppm/°C
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Power rating: May be equal or higher than 0.25W
• Operating temperature range: May be equal or extended
• Physical dimensions: May vary within axial package constraints
• Packaging format: Cut Tape (CT) or Tape & Reel (TR) acceptable
• Manufacturer: Alternative qualified manufacturers permitted

Two substitute parts meet these criteria: CMF5023K200FHEB (manufacturer-recommended direct equivalent) and CMF5523K200FHEB (upgrade option with higher power rating).

Parameter Comparison

Engineering Selection Recommendations

CMF5023K200FHEB (Manufacturer-Recommended Substitute): This part is the direct electrical equivalent to the RNF14FTC23K2, maintaining identical resistance, tolerance, power rating, and temperature coefficient specifications. Both parts are ROHS3 compliant and active in production. The CMF5023K200FHEB offers an extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and includes moisture-resistant features. Physical dimensions are smaller, which may provide layout advantages in space-constrained applications. This part is suitable for direct replacement in applications where the original specification is maintained.

CMF5523K200FHEB (Upgrade Option): This part provides identical electrical characteristics with a higher power rating of 0.5W (1/2W) compared to the 0.25W rating of the main part. The upgrade is applicable in circuits where thermal margin or power dissipation headroom is beneficial. Extended operating temperature range (-55°C ~ 175°C) and moisture-resistant construction are included. This part is suitable for applications where increased power handling capacity is acceptable or advantageous.

Both substitute parts are manufactured by Vishay Dale, an established supplier with active product status and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can CMF5023K200FHEB be used as a direct replacement for RNF14FTC23K2? A: Yes. Both parts share identical resistance value (23.2 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±50ppm/°C), and composition (metal film). Both are ROHS3 compliant and active products. The CMF5023K200FHEB has a smaller physical footprint and extended temperature range.

Q: What is the difference between CMF5023K200FHEB and CMF5523K200FHEB? A: The primary difference is power rating. CMF5023K200FHEB is rated at 0.25W (1/4W), matching the original part. CMF5523K200FHEB is rated at 0.5W (1/2W), providing higher power dissipation capability. Both maintain identical resistance, tolerance, and temperature coefficient specifications.

Q: Can I use the 0.5W version (CMF5523K200FHEB) in place of the 0.25W version? A: Yes, in applications where the circuit design permits. A higher power rating provides additional thermal margin and is electrically compatible. Physical dimensions differ slightly; verify PCB layout compatibility before substitution.

Q: Are there packaging format differences between these parts? A: Yes. The RNF14FTC23K2 is supplied in Tape & Reel (TR) format. Both substitute parts are supplied in Cut Tape (CT) format. Verify packaging requirements for your procurement and assembly processes.

Q: Do all three parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
