Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF601K0000FLEB is determined by the following criteria:

Electrical Compatibility: All substitute parts maintain the same 1 kOhms resistance value and 1W power rating. Tolerance variations (±1% to ±0.1%) represent improved precision grades and are electrically compatible. Temperature coefficient differences (±50ppm/°C to ±150ppm/°C) fall within acceptable ranges for standard applications.

Mechanical Compatibility: All substitute parts share identical physical dimensions (0.145" Dia x 0.344" L) and axial package configuration, ensuring direct board-level compatibility.

Environmental Specifications: All parts maintain the same operating temperature range (-55°C ~ 175°C), flame retardant coating, and moisture-resistant properties.

Packaging Format: Substitutes are available in three packaging options: Tape & Reel (TR), Cut Tape (CT), and Bulk. Packaging selection depends on assembly process requirements rather than electrical performance.

Parameter Comparison

Engineering Selection Recommendations

CMF601K0000BHEB (±0.1% Tolerance): This substitute provides improved tolerance specification with ±0.1% accuracy and reduced temperature coefficient (±50ppm/°C). Selection is appropriate for applications requiring tighter resistance tolerances. Available in Cut Tape packaging with 1727 units in stock. REACH status differs from the main part (Unaffected vs. Affected).

CMF601K0000FHEK (±50ppm/°C Temperature Coefficient): This substitute maintains ±1% tolerance matching the main part while offering improved temperature stability (±50ppm/°C vs. ±150ppm/°C). Available in Bulk packaging with the highest inventory level (6789 units). REACH status is Unaffected.

CMF601K0000FKEB (±100ppm/°C Temperature Coefficient): This substitute provides intermediate temperature coefficient performance (±100ppm/°C) with ±1% tolerance. Available in Cut Tape packaging with 4899 units in stock. REACH status is Unaffected.

All substitutes maintain ROHS3 compliance and identical physical dimensions, supporting direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can CMF601K0000BHEB replace CMF601K0000FLEB in any application?

A: CMF601K0000BHEB is electrically compatible as a direct substitute. The ±0.1% tolerance represents improved precision compared to the ±1% specification of the main part. Physical dimensions and power rating are identical. Packaging differs (Cut Tape vs. Tape & Reel), which may affect assembly process compatibility.

Q: What is the difference between the temperature coefficient values?

A: Temperature coefficient indicates resistance value change per degree Celsius. CMF601K0000FLEB has ±150ppm/°C, while CMF601K0000BHEB and CMF601K0000FHEK have ±50ppm/°C. Lower values indicate better stability across temperature variations. Selection depends on application temperature range and acceptable resistance drift.

Q: Are all substitutes available in the same packaging format?

A: No. CMF601K0000FLEB is supplied in Tape & Reel (TR) format. Substitutes are available in Cut Tape (CT) or Bulk packaging. Packaging selection should align with assembly equipment and production volume requirements.

Q: Do all parts meet the same compliance standards?

A: All parts are ROHS3 compliant. REACH status varies: CMF601K0000FLEB is REACH Affected, while all three substitutes are REACH Unaffected. Compliance requirements should be verified against specific application regulations.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, all parts share identical physical dimensions (0.145" Dia x 0.344" L) and axial configuration. Board-level compatibility is maintained. Packaging format differences do not affect installed component performance.
