Substitute Part Grouping Explanation

Substitute parts for the CMF55100R00FKBF are identified based on the following allowable parameters:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package type: Axial through-hole (exact match required)
• Composition: Metal Film (exact match required)
• Operating temperature range: -55°C to 175°C (minimum requirement)
• Physical dimensions: 0.090" Dia x 0.240" L (exact match required)
• Features: Flame Retardant Coating, Moisture Resistant, Safety (required)

Substitutes are grouped into two categories:

1. Upgrade Substitute: CMF55100R00DHR6 - Offers improved tolerance (±0.5% vs ±1%) and lower temperature coefficient (±50ppm/°C vs ±100ppm/°C) while maintaining all other core parameters.

2. Parametric Equivalent: CMF55100R00FKEK - Maintains identical electrical and mechanical specifications with differences in packaging format and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

CMF55100R00DHR6 (Upgrade Substitute) is suitable for applications requiring tighter tolerance control and improved temperature stability. The ±0.5% tolerance and ±50ppm/°C temperature coefficient provide enhanced precision compared to the main part. This substitute maintains RoHS non-compliant and REACH Affected status identical to the primary part. Selection of this upgrade is appropriate when circuit design specifications demand reduced resistance drift over temperature and tighter component matching.

CMF55100R00FKEK (Parametric Equivalent) provides direct functional equivalence with identical electrical specifications. This part offers ROHS3 compliance and REACH Unaffected status, making it suitable for applications subject to stricter environmental and regulatory requirements. The parametric equivalence ensures drop-in compatibility for standard applications where the primary part's compliance status is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can CMF55100R00DHR6 be used as a direct replacement for CMF55100R00FKBF?

A: Yes. CMF55100R00DHR6 is electrically and mechanically compatible. The primary differences are improved tolerance (±0.5% vs ±1%) and lower temperature coefficient (±50ppm/°C vs ±100ppm/°C). The packaging format differs (Cut Tape vs Bulk), which affects procurement and handling but not circuit performance.

Q: What is the difference between CMF55100R00FKEK and CMF55100R00FKBF?

A: Both parts are parametric equivalents with identical resistance, tolerance, power rating, and temperature range. The key differences are packaging format (Bulk for both) and compliance certifications. CMF55100R00FKEK is ROHS3 Compliant and REACH Unaffected, while CMF55100R00FKBF is RoHS non-compliant and REACH Affected.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical physical dimensions (0.090" Dia x 0.240" L) and axial package type, ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: Which substitute should I select for a new design?

A: Selection depends on application requirements. For standard applications, CMF55100R00FKEK offers regulatory compliance advantages. For precision circuits requiring tight tolerance and temperature stability, CMF55100R00DHR6 is the appropriate choice.

Q: Do packaging format differences affect circuit performance?

A: No. Packaging format (Bulk vs Cut Tape) affects procurement, storage, and assembly processes but does not impact electrical or mechanical performance in the final circuit.
