Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC16K2 are qualified based on the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Resistance value: 16.2 kOhms
• Tolerance: ±1%
• Composition: Metal Film
• Temperature Coefficient: ±50ppm/°C
• Package Type: Axial
• RoHS Compliance: ROHS3 Compliant

Allowable Variations:

• Power rating may be equal or higher (0.25W or greater)
• Operating temperature range may be equal or extended
• Physical dimensions may vary within axial package constraints
• Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical compatibility
• Additional features (Moisture Resistant) do not disqualify substitution

The substitute parts CMF5516K200FHEB and CMF5016K200FHEB meet all critical parameters while offering enhanced operating temperature ranges and moisture resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

CMF5016K200FHEB (Manufacturer Recommended): This part provides direct electrical and mechanical equivalence to the RNF14FTC16K2 with identical power rating (0.25W) and package dimensions optimized for the same PCB footprint. The extended operating temperature range (-55°C ~ 175°C) and moisture-resistant coating provide enhanced reliability margins. This part is the preferred substitute when form factor and thermal performance are critical design constraints.

CMF5516K200FHEB (Upgrade Option): This part offers increased power dissipation capability (0.5W vs. 0.25W) while maintaining the same resistance and tolerance specifications. The larger physical envelope accommodates higher power handling. This substitute is suitable for applications where thermal margin improvement is beneficial or where circuit redesign permits the larger form factor. The extended operating temperature range and moisture resistance provide additional environmental protection.

Both substitute parts maintain ROHS3 compliance and are manufactured by Vishay Dale, an established supplier with equivalent quality certifications to the original part.

Frequently Asked Questions (FAQ)

Q: Can CMF5516K200FHEB be used as a direct replacement for RNF14FTC16K2?

A: CMF5516K200FHEB is electrically compatible but has a larger physical envelope (0.090" Dia x 0.240" L vs. 0.093" Dia x 0.250" L). Verify PCB layout clearances before substitution. The higher power rating (0.5W) does not create compatibility issues in circuits designed for 0.25W operation.

Q: What is the difference between the two substitute parts?

A: CMF5016K200FHEB matches the original power rating (0.25W) with smaller dimensions (0.065" Dia x 0.150" L). CMF5516K200FHEB provides double the power rating (0.5W) with intermediate dimensions. Both maintain identical electrical specifications (16.2 kOhms ±1%, ±50ppm/°C).

Q: Are packaging format differences (Tape & Reel vs. Cut Tape) significant?

A: Packaging format affects handling and assembly processes but does not impact electrical or mechanical compatibility. Tape & Reel (TR) is optimized for automated assembly; Cut Tape (CT) is suitable for manual or mixed-volume assembly. Select based on production requirements.

Q: Do the substitute parts have better environmental performance?

A: Both substitute parts extend the operating temperature range to -55°C ~ 175°C (vs. -55°C ~ 155°C) and include moisture-resistant coating. These enhancements provide broader environmental tolerance but are not required for direct functional replacement.

Q: Are all parts RoHS compliant?

A: Yes. RNF14FTC16K2, CMF5516K200FHEB, and CMF5016K200FHEB are all ROHS3 compliant with REACH Unaffected status.
