Substitute Part Grouping Explanation

Substitution eligibility for the CMF55330R00FKBF is determined by strict equivalence across the following critical parameters:

• Resistance value: 330 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 type: Axial (exact match required)
• Operating temperature range: -55°C to 175°C (exact match required)
• Physical dimensions: 0.090" Dia x 0.240" L (exact match required)
• Termination count: 2 (exact match required)

The CMF55330R00FHBF qualifies as a direct substitute based on full alignment with all critical electrical and mechanical parameters. Secondary performance characteristics such as temperature coefficient may vary within acceptable engineering tolerances without affecting functional interchangeability in standard applications.

Parameter Comparison

Both parts maintain equivalent RoHS non-compliant and REACH Affected status, ensuring consistent regulatory treatment in design documentation and supply chain management.

Frequently Asked Questions (FAQ)

Q: Can CMF55330R00FHBF be used as a direct replacement for CMF55330R00FKBF?

A: Yes. Both parts share identical resistance (330 Ohms), tolerance (±1%), power rating (0.5W), composition (metal film), package type (axial), operating temperature range (-55°C to 175°C), and physical dimensions (0.090" Dia x 0.240" L). They are functionally interchangeable in standard circuit applications.

Q: What is the difference between these two parts?

A: The primary difference is temperature coefficient: CMF55330R00FKBF specifies ±100ppm/°C while CMF55330R00FHBF specifies ±50ppm/°C. The substitute part offers superior temperature stability. Inventory levels also differ, with CMF55330R00FHBF having higher availability.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS non-compliant and REACH Affected status. Regulatory treatment and documentation requirements are equivalent.

Q: Will the axial package dimensions fit the same PCB footprint?

A: Yes. Both parts have identical physical dimensions (0.090" Dia x 0.240" L / 2.29mm x 6.10mm) and axial package configuration, ensuring compatibility with existing through-hole layouts.

Q: Which part should be selected for temperature-sensitive applications?

A: Selection is based on application requirements. CMF55330R00FHBF provides tighter temperature coefficient performance (±50ppm/°C) for applications requiring enhanced stability across the -55°C to 175°C operating range.
