Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF601K5000FKBF is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.5 kOhms
• Power rating: 1W
• Package type: Axial
• Physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Operating temperature range: -55°C to 175°C
• Composition: Metal Film
• Manufacturer: Vishay Dale
• Series: CMF

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±1% or better)
• Temperature coefficient: May be equal or lower (±100ppm/°C or better)

The CMF601K5000BEBF qualifies as a direct substitute based on identical resistance, power rating, package configuration, and operating temperature range. The substitute provides improved tolerance (±0.1% versus ±1%) and superior temperature coefficient (±25ppm/°C versus ±100ppm/°C), making it suitable for applications with stricter accuracy requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CMF601K5000FKBF and CMF601K5000BEBF maintain active product status with current manufacturing support. Selection between these components depends on application-specific tolerance and stability requirements:

CMF601K5000FKBF Selection Criteria:

• Applications where ±1% tolerance meets circuit specifications
• Standard industrial applications with moderate accuracy requirements
• Cost-optimized designs where tighter tolerance is not required

CMF601K5000BEBF Selection Criteria:

• Precision applications requiring ±0.1% tolerance
• Circuits sensitive to resistance drift across temperature variations
• Applications where superior temperature coefficient (±25ppm/°C) provides performance advantage
• Higher inventory availability (1214 units versus 761 units)

Both components share identical physical dimensions, power rating, operating temperature range, and protective features, ensuring direct mechanical and thermal compatibility. RoHS non-compliance status is consistent across both parts.

Frequently Asked Questions (FAQ)

Q: Can CMF601K5000BEBF replace CMF601K5000FKBF in existing designs?

A: Yes. The substitute maintains identical resistance value, power rating, package configuration, and physical dimensions. The improved tolerance and temperature coefficient of the substitute provide equal or superior performance in all applications where the original part functions.

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