Parameter Comparison

Engineering Selection Recommendations

CMF552K2000GKBF (Original Part): Use this part for applications where ±2% tolerance is acceptable and cost optimization is prioritized. The part is active and maintains full operational specifications across the -55°C to 175°C temperature range.

CMF552K2000FHEK (Substitute): Select this part when tighter tolerance (±1%) and lower temperature coefficient (±50ppm/°C) are required for precision circuit applications. This substitute offers improved stability and is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. Inventory availability is higher at 6028 units.

CMF552K2000FKEK (Substitute): Select this part when ±1% tolerance is required while maintaining the original temperature coefficient specification (±100ppm/°C). This substitute is ROHS3 compliant and REACH unaffected. Inventory availability is 5542 units.

All substitutes maintain identical mechanical fit, electrical power rating, and operating temperature range, ensuring direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can CMF552K2000FHEK or CMF552K2000FKEK be used as direct replacements for CMF552K2000GKBF?

A: Yes. Both substitutes maintain identical resistance value (2.2 kOhms), power rating (0.5W), package type (axial), and physical dimensions (0.090" Dia x 0.240" L). They are electrically and mechanically compatible for direct board-level substitution.

Q: What is the primary difference between the two substitute parts?

A: CMF552K2000FHEK offers both tighter tolerance (±1%) and lower temperature coefficient (±50ppm/°C), providing superior stability. CMF552K2000FKEK offers tighter tolerance (±1%) while maintaining the original temperature coefficient (±100ppm/°C). Selection depends on whether improved temperature stability is required.

Q: Are the substitute parts compliant with current regulatory standards?

A: Yes. Both CMF552K2000FHEK and CMF552K2000FKEK are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.

Q: Will substituting these parts affect circuit performance?

A: The tighter tolerance in both substitutes (±1% versus ±2%) will reduce resistance value variation, potentially improving circuit accuracy. The lower temperature coefficient in CMF552K2000FHEK will reduce resistance drift across temperature extremes. Both effects are beneficial or neutral for most applications.

Q: Are there any package or footprint differences?

A: No. All three parts share identical axial package configuration and physical dimensions (0.090" Dia x 0.240" L / 2.29mm x 6.10mm), ensuring identical PCB footprint and mounting compatibility.

Q: What inventory levels are available for each part?

A: CMF552K2000GKBF has 956 units in stock. CMF552K2000FHEK has 6028 units in stock. CMF552K2000FKEK has 5542 units in stock.
