Substitute Part Grouping Explanation

Substitute parts for the CMF55110K00FKBF are classified based on electrical and mechanical compatibility within the CMF series. Substitution eligibility is determined by the following parameters:

Primary Compatibility Criteria:

• Resistance value: 110 kOhms (exact match required)
• Power rating: 0.5W (1/2W) (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.090" Dia x 0.240" L (exact match required)
• Composition: Metal Film (exact match required)
• Operating temperature range: -55°C to 175°C (exact match required)

Secondary Variation Parameters:

• Tolerance: ±1% or tighter (±0.5%)
• Temperature coefficient: ±100ppm/°C or lower (±50ppm/°C)
• Packaging format: Bulk or Tape & Reel
• RoHS compliance status

Two substitute parts meet these criteria: CMF55110K00FKEK (parametric equivalent with improved RoHS compliance) and CMF55110K00DHR6 (upgrade with tighter tolerance and lower temperature coefficient).

Parameter Comparison

Engineering Selection Recommendations

CMF55110K00FKEK Selection Criteria: CMF55110K00FKEK is a parametric equivalent suitable for applications where RoHS3 compliance is required. This part maintains identical electrical specifications (110 kOhms ±1%, 0.5W, ±100ppm/°C) and physical dimensions as the main part. The primary distinction is ROHS3 compliance status, making it appropriate for procurement into regulated supply chains or end-use applications subject to RoHS directives. Bulk packaging format matches the main part specification.

CMF55110K00DHR6 Selection Criteria: CMF55110K00DHR6 is an upgrade substitute offering improved tolerance (±0.5% versus ±1%) and lower temperature coefficient (±50ppm/°C versus ±100ppm/°C). This part is suitable for applications requiring enhanced accuracy and stability across the operating temperature range. The Tape & Reel packaging format differs from the main part's bulk format, affecting procurement and handling procedures. This substitute is appropriate when tighter tolerance specifications are mandated by circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can CMF55110K00FKEK be used as a direct replacement for CMF55110K00FKBF?

A: Yes. CMF55110K00FKEK is a parametric equivalent with identical electrical and mechanical specifications. The primary difference is RoHS3 compliance status. Direct substitution is supported for applications where RoHS compliance is required or preferred.

Q: What is the difference between CMF55110K00DHR6 and the main part?

A: CMF55110K00DHR6 provides tighter tolerance (±0.5% versus ±1%) and lower temperature coefficient (±50ppm/°C versus ±100ppm/°C). Both parts share identical resistance value, power rating, package type, and physical dimensions. The upgrade is suitable for precision applications requiring enhanced accuracy.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Bulk versus Tape & Reel) does not affect electrical or mechanical performance. The difference is operational: Bulk packaging is used for manual assembly or small-quantity applications, while Tape & Reel format is used for automated assembly processes.

Q: Are all substitute parts rated for the same temperature range?

A: Yes. All listed parts operate across the identical temperature range of -55°C to 175°C. Temperature coefficient values differ, affecting stability within this range.

Q: Can CMF55110K00DHR6 be used in applications designed for ±1% tolerance?

A: Yes. CMF55110K00DHR6 with ±0.5% tolerance exceeds the ±1% specification, providing superior accuracy. Tighter tolerance is backward-compatible with applications designed for looser tolerance specifications.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient indicates resistance value drift per degree Celsius change. CMF55110K00DHR6 at ±50ppm/°C exhibits half the drift rate of the main part at ±100ppm/°C, resulting in improved stability across temperature variations.
