Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF55210R00FKBF is determined by the following critical parameters:

• Resistance value: 210 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)
• Series: CMF (exact match required)

The identified substitute part CMF55210R00FHEB meets all mandatory electrical and mechanical parameters. The primary difference is packaging format (Cut Tape versus Bulk) and temperature coefficient specification (±50ppm/°C versus ±100ppm/°C), with improved RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both CMF55210R00FKBF and CMF55210R00FHEB are Active status components suitable for 210 Ohm, 1/2W axial resistor applications. Selection between these parts should be based on:

Packaging requirements: The main part is supplied in Bulk packaging, while the substitute is supplied in Cut Tape format. Choose based on assembly process and procurement workflow.

Compliance requirements: CMF55210R00FHEB provides ROHS3 compliance, whereas CMF55210R00FKBF is RoHS non-compliant. Applications subject to RoHS3 regulatory requirements must use CMF55210R00FHEB.

Temperature coefficient: CMF55210R00FHEB offers improved temperature stability at ±50ppm/°C compared to ±100ppm/°C for the main part. Applications requiring tighter temperature coefficient performance should specify CMF55210R00FHEB.

Both parts share identical electrical specifications (210 Ohms ±1%, 0.5W), physical dimensions, and operating temperature range (-55°C to 175°C), ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CMF55210R00FHEB be used as a direct replacement for CMF55210R00FKBF?

A: Yes. Both parts are electrically and mechanically identical in resistance value (210 Ohms ±1%), power rating (0.5W), composition (metal film), package type (axial), and physical dimensions (0.090" Dia x 0.240" L). The substitute part offers improved RoHS3 compliance and tighter temperature coefficient specification.

Q: What is the difference in packaging between these two parts?

A: CMF55210R00FKBF is supplied in Bulk packaging, while CMF55210R00FHEB is supplied in Cut Tape (CT) format. Bulk packaging is typically used for large-volume orders, while Cut Tape is standard for automated assembly processes. Select based on your procurement and manufacturing requirements.

Q: Does the temperature coefficient difference affect circuit performance?

A: The temperature coefficient difference (±100ppm/°C versus ±50ppm/°C) affects resistor stability across temperature variations. CMF55210R00FHEB provides superior temperature stability. For applications operating across the full -55°C to 175°C range with tight tolerance requirements, CMF55210R00FHEB is the preferred choice.

Q: Are there any compliance differences between these parts?

A: CMF55210R00FHEB is ROHS3 compliant, while CMF55210R00FKBF is RoHS non-compliant. Applications subject to RoHS3 regulations must use CMF55210R00FHEB. Both parts are REACH Affected and classified as EAR99.

Q: Can I use these parts interchangeably in my circuit design?

A: Yes, provided your application does not have specific compliance or temperature coefficient requirements. Both parts maintain identical electrical performance (210 Ohms ±1%, 0.5W) and physical form factor (axial, 0.090" Dia x 0.240" L), ensuring functional compatibility in circuit applications.
