Substitute Part Grouping Explanation

Substitution of the CMF5510R000FKBF39 is determined by strict equivalence across the following parameters:

• Resistance value: 10 Ohms
• Tolerance: ±1%
• Power rating: 0.5W
• Composition: Metal Film
• Package: Axial through-hole
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 175°C
• Physical dimensions: 0.090" Dia x 0.240" L
• Features: Flame retardant coating, moisture resistant

The CMF5510R000FKEK meets all these electrical and mechanical parameters and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products from Vishay Dale with identical electrical and mechanical specifications. The primary distinction lies in compliance certifications. The CMF5510R000FKEK offers ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to European regulatory requirements. The CMF5510R000FKBF39 is RoHS non-compliant and REACH affected. Selection between these parts should be based on the regulatory environment and compliance requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can CMF5510R000FKEK replace CMF5510R000FKBF39 in existing designs?
