Substitute Part Grouping Explanation

Substitution of CMF55154K00FKBF is permissible with CMF55154K00FHEB based on the following criteria:

Matching Parameters (Substitution Basis):

• Resistance value: 154 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Package type: Axial
• Operating temperature range: -55°C to 175°C
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Features: Flame Retardant Coating, Moisture Resistant, Safety
• Series: CMF55
• Manufacturer: Vishay Dale

Allowed Variation:

• Packaging format: Bulk (CMF55154K00FKBF) vs. Cut Tape (CMF55154K00FHEB)
• Temperature coefficient: ±100ppm/°C vs. ±50ppm/°C
• RoHS compliance status: Non-compliant vs. ROHS3 Compliant
• REACH status: Affected vs. Unaffected

Parameter Comparison

Engineering Selection Recommendations

CMF55154K00FKBF is suitable for applications where bulk packaging is preferred and RoHS non-compliance is acceptable. The ±100ppm/°C temperature coefficient is appropriate for general-purpose applications with standard thermal stability requirements.

CMF55154K00FHEB is the preferred substitute when RoHS3 compliance and REACH compliance are mandatory requirements. The improved temperature coefficient of ±50ppm/°C provides superior thermal stability. Cut Tape packaging is standard for automated assembly processes. Both parts maintain identical electrical performance and physical compatibility.

Selection between these parts depends on regulatory compliance requirements and packaging format needs for your assembly process.

Frequently Asked Questions (FAQ)

Q: Are CMF55154K00FKBF and CMF55154K00FHEB electrically interchangeable?

A: Yes. Both parts have identical resistance (154 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), and operating temperature range (-55°C to 175°C). The temperature coefficient difference (±100ppm/°C vs. ±50ppm/°C) does not prevent substitution in standard applications.

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

A: CMF55154K00FKBF is supplied in Bulk packaging, while CMF55154K00FHEB is supplied in Cut Tape (CT) format. Cut Tape packaging is optimized for automated pick-and-place assembly, whereas Bulk packaging is suitable for manual assembly or reel-based processes.

Q: Does the temperature coefficient difference affect component selection?

A: The CMF55154K00FHEB has a tighter temperature coefficient (±50ppm/°C) compared to CMF55154K00FKBF (±100ppm/°C). This provides better stability across temperature variations. Selection depends on your application's thermal stability requirements.

Q: What are the compliance differences?

A: CMF55154K00FHEB is ROHS3 compliant and REACH unaffected, making it suitable for regulated markets. CMF55154K00FKBF is RoHS non-compliant and REACH affected. Compliance requirements determine which part is appropriate for your application.

Q: Can I use CMF55154K00FHEB as a direct replacement for CMF55154K00FKBF?

A: Yes, provided your assembly process accommodates Cut Tape packaging and your application meets or does not require RoHS3 compliance. Physical dimensions and electrical specifications are identical.
