Key Parameters

Substitute Part Grouping Explanation

Substitute parts for CMF552K2000JLEK are qualified based on the following criteria:

Primary Matching Parameters:

• Resistance value: 2.2 kOhms (exact match required)
• Package configuration: Axial through-hole
• Composition: Metal film
• Tolerance: ±5% or better (tighter tolerance acceptable)
• Power rating: Equal to or greater than 0.5W
• Operating temperature range: Minimum -55°C ~ 175°C or equivalent coverage

Acceptable Variations:

• Tolerance may be tighter (±1%) than the original specification
• Power rating may exceed 0.5W (1W acceptable)
• Temperature coefficient may differ within metal film resistor standards
• Physical dimensions may vary slightly within axial package specifications

Parameter Comparison

Engineering Selection Recommendations

CMF552K2000FHEK (Vishay Dale): Direct upgrade within the same manufacturer series. Tighter tolerance (±1%) and lower temperature coefficient (±50ppm/°C) provide improved stability. REACH Unaffected status offers regulatory advantage. Identical power rating and operating temperature range. Recommended for applications requiring enhanced precision.

CMF552K2000FKEK (Vishay Dale): Direct upgrade within the same manufacturer series. Tighter tolerance (±1%) with moderate temperature coefficient (±100ppm/°C). REACH Unaffected status. Identical power rating and operating temperature range. Suitable for general-purpose applications requiring improved tolerance performance.

FMP100JR-52-2K2 (YAGEO): Cross-manufacturer substitute with higher power rating (1W vs. 0.5W). Maintains ±5% tolerance and ROHS3 compliance. Operating temperature range extends to -55°C ~ 155°C (5°C lower maximum). REACH Unaffected status. Applicable where increased power dissipation capability is beneficial or where YAGEO sourcing is preferred.

Frequently Asked Questions (FAQ)

Q: Can CMF552K2000FHEK replace CMF552K2000JLEK in all applications? A: Yes. CMF552K2000FHEK maintains identical resistance, power rating, package configuration, and operating temperature range. The tighter tolerance (±1% vs. ±5%) and improved temperature coefficient represent performance enhancements compatible with all applications designed for the original part.

Q: What is the difference between the two Vishay Dale upgrades? A: CMF552K2000FHEK features ±50ppm/°C temperature coefficient, while CMF552K2000FKEK features ±100ppm/°C. Both offer ±1% tolerance. Selection depends on thermal stability requirements of the specific application.

Q: Is FMP100JR-52-2K2 suitable for 0.5W applications? A: Yes. The 1W power rating of FMP100JR-52-2K2 exceeds the 0.5W requirement, providing additional thermal margin. The component is electrically and mechanically compatible. The maximum operating temperature is 155°C versus 175°C for the original part.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance. CMF552K2000FHEK and CMF552K2000FKEK are REACH Unaffected, while the original CMF552K2000JLEK is REACH Affected.

Q: Do physical dimensions differ between substitute parts? A: Axial package dimensions are consistent across Vishay Dale parts (0.090" Dia x 0.240" L). FMP100JR-52-2K2 has slightly larger dimensions (0.094" Dia x 0.248" L) due to higher power rating, but remains compatible with standard axial component footprints.
