Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF5518R200FKBF is determined by the following critical parameters:

• Resistance value: 18.2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 175°C (exact match required)
• Physical dimensions: 0.090" Dia × 0.240" L (exact match required)

The CMF5518R200FHEB qualifies as a direct substitute based on identical electrical specifications and mechanical form factor. Differences exist only in packaging format (Cut Tape versus Bulk) and product compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CMF5518R200FHEB serves as a direct electrical and mechanical substitute for the CMF5518R200FKBF. Selection between these parts should be based on the following criteria:

CMF5518R200FKBF is appropriate for applications where bulk packaging is required and RoHS/REACH compliance is not a design constraint.

CMF5518R200FHEB is appropriate for applications requiring ROHS3 compliance and REACH unaffected status. This variant offers improved temperature coefficient performance (±50ppm/°C versus ±100ppm/°C), providing enhanced stability in temperature-sensitive applications. Cut Tape packaging supports automated assembly processes and reduces component waste.

Both parts maintain identical electrical performance in standard operating conditions within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can CMF5518R200FHEB replace CMF5518R200FKBF in existing designs?

A: Yes. Both parts are electrically and mechanically identical with respect to resistance value, tolerance, power rating, composition, and physical dimensions. The substitute accommodates different packaging requirements and compliance specifications.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies loose components suitable for manual assembly or bin storage. Cut Tape packaging provides components on continuous tape, optimized for automated pick-and-place assembly equipment and component counting.

Q: Does the temperature coefficient difference affect circuit performance?

A: The CMF5518R200FHEB exhibits a lower temperature coefficient (±50ppm/°C) compared to the main part (±100ppm/°C). This results in improved resistance stability across the operating temperature range of -55°C to 175°C. Selection depends on circuit tolerance requirements.

Q: Are there compliance differences between these parts?

A: Yes. The CMF5518R200FHEB is ROHS3 compliant and REACH unaffected, while the CMF5518R200FKBF is RoHS non-compliant and REACH affected. Applications subject to environmental regulations should specify the compliant variant.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. Bulk packaging requires manual placement; Cut Tape packaging integrates with automated assembly systems. Electrical performance is equivalent in both cases.
