Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 2 kOhms
• Power rating: 0.5W (1/2W)
• Package type: Axial through-hole
• Composition: Metal Film
• Number of terminations: 2

Allowable Variation Parameters:

• Tolerance: ±1% or tighter (±0.1% acceptable)
• Temperature coefficient: ±100ppm/°C or better (±50ppm/°C acceptable)
• Operating temperature range: Must encompass or match the -55°C ~ 175°C range
• RoHS and REACH compliance status may differ
• Physical dimensions may vary within axial package constraints
• Packaging format (Bulk vs. Cut Tape) does not affect electrical substitution

Non-Substitutable Parameters:

• Resistance value
• Power rating
• Package configuration (axial only)
• Composition (metal film only)

Engineering Selection Recommendations

CMF552K0000BHEK (Upgrade Option) This part is electrically and mechanically identical to the main part with improved tolerance (±0.1% vs. ±1%) and superior temperature coefficient (±50ppm/°C vs. ±100ppm/°C). It achieves ROHS3 compliance and REACH unaffected status, addressing regulatory requirements. Physical dimensions are identical. Selection is appropriate when tighter tolerance specifications are required or when regulatory compliance is mandatory.

CMF552K0000FHEK (Direct Substitute) This part matches the main part in all critical electrical parameters: 2 kOhms ±1%, 0.5W power rating, and ±100ppm/°C temperature coefficient. It provides improved temperature coefficient (±50ppm/°C) and achieves ROHS3 compliance and REACH unaffected status. Physical dimensions are identical. Selection is appropriate as a direct replacement with enhanced compliance.

CMF552K0000FKEK (Parametric Equivalent) This part is electrically and mechanically equivalent to the main part with identical tolerance (±1%) and temperature coefficient (±100ppm/°C). It achieves ROHS3 compliance and REACH unaffected status. Physical dimensions are identical. Selection is appropriate when compliance upgrades are needed without changing electrical performance.

RNF12FTD2K00 (Cross-Manufacturer Substitute) This Stackpole Electronics part matches the main part in resistance (2 kOhms), tolerance (±1%), power rating (0.5W), and temperature coefficient (±100ppm/°C). It achieves ROHS3 compliance and REACH unaffected status. Physical dimensions differ (0.108" Dia x 0.344" L vs. 0.090" Dia x 0.240" L), requiring PCB layout verification. Operating temperature range is -55°C ~ 155°C, which does not extend to 175°C. Selection is appropriate for supply chain diversification when board space permits the larger footprint and maximum operating temperature of 155°C is acceptable.

Frequently Asked Questions (FAQ)

Q: Can CMF552K0000BHEK replace CMF552K0000FKBF in all applications? A: Yes. CMF552K0000BHEK meets all mandatory electrical parameters and provides improved tolerance and temperature coefficient. It is physically identical and achieves superior compliance status.

Q: What is the primary difference between CMF552K0000FHEK and CMF552K0000FKEK? A: Both parts are direct substitutes with identical electrical specifications. CMF552K0000FHEK has a superior temperature coefficient (±50ppm/°C vs. ±100ppm/°C). Both achieve ROHS3 compliance.

Q: Can RNF12FTD2K00 be used as a direct replacement? A: RNF12FTD2K00 is electrically equivalent but has a larger physical footprint (0.108" Dia x 0.344" L vs. 0.090" Dia x 0.240" L) and a lower maximum operating temperature (155°C vs. 175°C). PCB layout verification is required. Use only if board space permits and the 155°C maximum temperature is acceptable for the application.

Q: Why does CMF552K0000FKBF show RoHS non-compliant status? A: The main part is listed as RoHS non-compliant and REACH affected. All substitute parts listed achieve ROHS3 compliance and REACH unaffected status, providing regulatory advantages.

Q: Are there packaging differences between these parts? A: CMF552K0000FKBF, CMF552K0000BHEK, CMF552K0000FHEK, and CMF552K0000FKEK are supplied in Bulk packaging. RNF12FTD2K00 is supplied in Cut Tape (CT) packaging. Packaging format does not affect electrical performance or substitution eligibility.

Q: What tolerance should I specify for critical circuit applications? A: For applications requiring tighter tolerance control, CMF552K0000BHEK provides ±0.1% tolerance. For standard applications, ±1% tolerance (main part and most substitutes) is acceptable.
