Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF14FTC16R9 are qualified based on the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Resistance value: 16.9 Ohms
• 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 or Cut Tape) may differ
• Additional features (Moisture Resistant) are permissible

Two substitute parts meet these criteria: CMF5516R900FHEB (0.5W upgrade) and CMF5016R900FHEB (direct 0.25W equivalent).

Parameter Comparison

Engineering Selection Recommendations

CMF5016R900FHEB is the direct equivalent substitute for the RNF14FTC16R9. Both components share identical electrical specifications (16.9 Ohms, ±1%, 0.25W, ±50ppm/°C) and maintain ROHS3 compliance. The CMF5016R900FHEB provides extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) and includes moisture resistant construction. This part is available in Tape & Reel packaging matching the original specification.

CMF5516R900FHEB serves as an upgrade substitute with doubled power rating (0.5W versus 0.25W). This part is suitable for applications where thermal margin or power dissipation headroom is required. The CMF5516R900FHEB maintains all other electrical parameters and compliance certifications. Physical dimensions are slightly reduced (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L), and packaging is provided in Cut Tape format.

Both substitute parts are manufactured by Vishay Dale, an established supplier with Active product status and confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CMF5016R900FHEB directly replace RNF14FTC16R9 in existing designs?

A: Yes. The CMF5016R900FHEB matches all critical electrical parameters (resistance, tolerance, power rating, temperature coefficient) and maintains identical package type (Axial). Both components are ROHS3 compliant and rated for the same operating temperature minimum (-55°C). The CMF5016R900FHEB extends the maximum operating temperature to 175°C.

Q: What is the primary difference between CMF5516R900FHEB and CMF5016R900FHEB?

A: The CMF5516R900FHEB has a 0.5W power rating compared to the 0.25W rating of CMF5016R900FHEB. All other electrical specifications remain identical. The higher power rating provides increased thermal capacity for applications with higher power dissipation requirements.

Q: Are there packaging format differences between the substitutes?

A: Yes. The RNF14FTC16R9 and CMF5016R900FHEB are supplied in Tape & Reel (TR) format. The CMF5516R900FHEB is supplied in Cut Tape (CT) format. Both formats are standard for through-hole axial resistors and do not affect electrical performance or board-level compatibility.

Q: Do the substitute parts have additional features compared to the original?

A: Both Vishay Dale substitutes include Moisture Resistant construction in addition to the Flame Retardant Coating and Safety features present in the RNF14FTC16R9. Moisture resistance provides enhanced reliability in humid environments without affecting electrical specifications.

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

A: All three parts use Axial package construction and are mechanically compatible for through-hole mounting. Minor dimensional variations exist: RNF14FTC16R9 is 0.093" Dia x 0.250" L, CMF5516R900FHEB is 0.090" Dia x 0.240" L, and CMF5016R900FHEB is 0.065" Dia x 0.150" L. These variations fall within standard axial resistor tolerances and do not affect PCB layout or mounting compatibility.
