Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14FTC16R2 is determined by the following critical parameters:

• Resistance value must be 16.2 Ohms
• Tolerance must be ±1% or tighter
• Composition must be metal film
• Temperature coefficient must be ±50ppm/°C or better
• Package must be axial through-hole
• Operating temperature range must encompass the application requirements
• RoHS3 compliance required

Two substitute parts meet these criteria with variations in power rating and physical dimensions. The CMF5016R200FHEB maintains identical power rating (0.25W) with enhanced operating temperature range. The CMF5516R200FHEB provides increased power dissipation capability (0.5W) for applications requiring higher thermal margin.

Parameter Comparison

Engineering Selection Recommendations

CMF5016R200FHEB is the direct functional equivalent to RNF14FTC16R2. Both components share identical electrical specifications (16.2 Ohms, ±1%, 0.25W, ±50ppm/°C) and axial package configuration. The CMF5016R200FHEB provides extended operating temperature range (-55°C to 175°C versus -55°C to 155°C) and adds moisture resistance features while maintaining ROHS3 compliance. Physical dimensions are smaller (1.65mm x 3.81mm), which may require PCB layout verification for mechanical fit.

CMF5516R200FHEB is suitable for applications where increased power dissipation margin is required. The 0.5W rating provides double the power handling capacity of the original specification. Operating temperature range extends to 175°C. Physical dimensions (2.29mm x 6.10mm) remain compatible with standard axial component spacing. This part is recommended when thermal analysis indicates potential stress at the 0.25W rating or when design margins require additional headroom.

Both substitute parts are active products with established supply availability and full compliance certifications matching the original component.

Frequently Asked Questions (FAQ)

Can CMF5016R200FHEB replace RNF14FTC16R2 in all applications?

Yes, CMF5016R200FHEB is electrically and mechanically equivalent. Verify PCB layout accommodates the smaller physical dimensions (1.65mm x 3.81mm versus 2.35mm x 6.35mm). The extended operating temperature range (-55°C to 175°C) provides additional margin beyond the original specification.

When should CMF5516R200FHEB be selected instead of CMF5016R200FHEB?

Select CMF5516R200FHEB when circuit analysis indicates power dissipation approaching or exceeding 0.25W, or when design specifications require thermal margin. The 0.5W rating provides enhanced reliability in high-ambient-temperature environments. Physical dimensions are nearly identical to the original part.

Are there packaging format differences between these parts?

Yes. RNF14FTC16R2 is supplied in Tape & Reel (TR) format. Both substitute parts (CMF5016R200FHEB and CMF5516R200FHEB) are supplied in Cut Tape (CT) format. Verify procurement and assembly processes accommodate the different packaging.

Do all parts meet the same compliance requirements?

All three parts are ROHS3 compliant and REACH unaffected. Both substitute parts add moisture resistance features not specified in the original component, providing additional environmental protection.

What is the impact of the smaller dimensions in CMF5016R200FHEB?

The CMF5016R200FHEB measures 1.65mm diameter x 3.81mm length compared to 2.35mm x 6.35mm for the original. Verify component spacing on the PCB and confirm lead-to-lead distance accommodates the smaller form factor. Electrical performance is identical.
