Substitute Part Grouping Explanation

Substitute parts for the CMF601K0000FKBF are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Resistance value: 1 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 175°C
• Physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Terminations: 2
• Features: Flame Retardant Coating, Moisture Resistant, Safety

The CMF601K0000FKEK meets all these criteria and is classified as a parametric equivalent. Both parts share the same base product number (CMF60) and series designation (CMF), confirming functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both CMF601K0000FKBF and CMF601K0000FKEK are electrically and mechanically identical. The primary distinction is RoHS compliance status: CMF601K0000FKBF is RoHS non-compliant, while CMF601K0000FKEK is ROHS3 compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. For applications subject to RoHS3 regulations, CMF601K0000FKEK is the appropriate choice. Both parts maintain identical electrical performance, temperature characteristics, and physical form factor, ensuring direct substitution without circuit redesign or board layout modification.
