Substitute Part Grouping Explanation

Substitute parts for the CMF55100K00FKBF are classified based on the following criteria:

Direct Manufacturer Substitute (CMF55100K00FKR6): Identical electrical specifications (100 kOhms, ±1%, 0.5W, ±100ppm/°C, -55°C to 175°C) and physical dimensions. Differs only in packaging format (Cut Tape instead of Bulk), making it suitable for automated assembly environments.

Upgrade Substitute (CMF55100K00DHR6): Maintains core electrical parameters (100 kOhms, 0.5W, -55°C to 175°C) but offers improved tolerance (±0.5% versus ±1%) and lower temperature coefficient (±50ppm/°C versus ±100ppm/°C). Packaging is Cut Tape. This part provides enhanced precision for applications requiring tighter component tolerances.

Parametric Equivalent (CMF55100K00FKEK): Matches all electrical and physical specifications of the main part (100 kOhms, ±1%, 0.5W, ±100ppm/°C, -55°C to 175°C, Axial package). Differs in packaging format (Bulk) and regulatory compliance status (ROHS3 Compliant, REACH Unaffected versus RoHS non-compliant, REACH Affected).

Parameter Comparison

Engineering Selection Recommendations

For Bulk Packaging Requirements: CMF55100K00FKBF and CMF55100K00FKEK are both available in bulk packaging. CMF55100K00FKEK is preferred when ROHS3 compliance and REACH unaffected status are required for end-product certification.

For Automated Assembly (Cut Tape Packaging): CMF55100K00FKR6 provides direct electrical equivalence with bulk-packaged main part but in cut tape format suitable for pick-and-place equipment.

For Enhanced Tolerance and Stability: CMF55100K00DHR6 offers ±0.5% tolerance and ±50ppm/°C temperature coefficient, providing superior precision compared to the ±1% tolerance and ±100ppm/°C of the main part. Selection depends on circuit requirements for component accuracy.

For Regulatory Compliance: CMF55100K00FKEK meets ROHS3 compliance and REACH unaffected requirements, making it suitable for applications subject to EU environmental directives.

Frequently Asked Questions (FAQ)

Q: Can CMF55100K00FKR6 be used as a direct replacement for CMF55100K00FKBF?

A: Yes. Both parts have identical electrical specifications (100 kOhms, ±1%, 0.5W, ±100ppm/°C, -55°C to 175°C) and physical dimensions. The difference is packaging format: CMF55100K00FKR6 is supplied in cut tape while CMF55100K00FKBF is supplied in bulk. Selection depends on assembly process requirements.

Q: What is the advantage of CMF55100K00DHR6 over the main part?

A: CMF55100K00DHR6 provides tighter tolerance (±0.5% versus ±1%) and lower temperature coefficient (±50ppm/°C versus ±100ppm/°C). These specifications result in improved component stability and accuracy over temperature variations and component aging. Use this part when circuit design requires enhanced precision.

Q: Is CMF55100K00FKEK a complete equivalent to CMF55100K00FKBF?

A: CMF55100K00FKEK matches all electrical and physical parameters of CMF55100K00FKBF. The key differences are regulatory compliance (ROHS3 Compliant and REACH Unaffected versus RoHS non-compliant and REACH Affected). Both are supplied in bulk packaging. Selection depends on product certification requirements.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes, provided the circuit design accommodates the specified tolerance and temperature coefficient ranges. All substitute parts maintain the same 100 kOhms resistance value, 0.5W power rating, and -55°C to 175°C operating temperature range. Verify that tighter tolerance specifications (CMF55100K00DHR6) do not conflict with circuit design intent.

Q: What packaging format should be selected for high-volume production?

A: Cut tape packaging (CMF55100K00FKR6 or CMF55100K00DHR6) is standard for automated assembly lines using pick-and-place equipment. Bulk packaging (CMF55100K00FKBF or CMF55100K00FKEK) is suitable for manual assembly or lower-volume applications.
