Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF6027K100FKBF is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27.1 kOhms
• Power rating: 1W
• Package type: Axial
• Composition: Metal Film
• Operating temperature range: -55°C to 175°C
• Physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Number of terminations: 2

Allowable Variation Parameters:

• Tolerance: May be tighter (lower value) than ±1%
• Temperature coefficient: May be lower (more stable) than ±100ppm/°C

The CMF6027K100BEBF qualifies as a direct substitute because it maintains all mandatory parameters while providing improved tolerance (±0.1% versus ±1%) and superior temperature coefficient stability (±25ppm/°C versus ±100ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the CMF6027K100FKBF and CMF6027K100BEBF maintain active product status from Vishay Dale with equivalent RoHS non-compliance and REACH affected classifications. Selection between these parts depends on application-specific tolerance and stability requirements:

The CMF6027K100FKBF is suitable for applications where ±1% tolerance and ±100ppm/°C temperature coefficient meet circuit specifications and cost optimization is prioritized.

The CMF6027K100BEBF is appropriate for applications requiring tighter tolerance control (±0.1%) and improved temperature stability (±25ppm/°C), with higher inventory availability (1529 units versus 1069 units).

Both parts share identical mechanical compatibility, thermal operating range, and protective features, ensuring direct substitution without circuit board redesign or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can CMF6027K100BEBF replace CMF6027K100FKBF in existing designs?

A: Yes. Both parts are mechanically and electrically compatible. The CMF6027K100BEBF provides superior tolerance and temperature coefficient performance while maintaining identical physical dimensions, power rating, and operating temperature range.

Q: What is the primary difference between these two resistors?

A: The CMF6027K100BEBF offers tighter tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±100ppm/°C). All other specifications, including resistance value, power rating, package type, and physical dimensions, are identical.

Q: Are there any compliance or certification differences?

A: Both parts share identical RoHS status (non-compliant), REACH status (affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090). No compliance differences exist between the two parts.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both resistors have identical physical dimensions (0.145" Dia x 0.344" L / 3.68mm x 8.74mm) and axial package configuration, ensuring direct mechanical compatibility without PCB modification.

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

A: The CMF6027K100BEBF is the appropriate choice for applications where temperature coefficient stability is critical, as it provides ±25ppm/°C performance compared to ±100ppm/°C for the CMF6027K100FKBF.
