Substitute Part Grouping Explanation

Substitution eligibility for the CMF554K7000FKBF is determined by strict equivalence across the following parameters:

• Resistance value: 4.7 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 175°C
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Features: Flame Retardant Coating, Moisture Resistant, Safety

The CMF554K7000FKEK meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both CMF554K7000FKBF and CMF554K7000FKEK are electrically and mechanically identical across all functional parameters. The primary distinction lies in regulatory compliance status:

The CMF554K7000FKEK provides ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to European Union environmental regulations. The CMF554K7000FKBF remains RoHS non-compliant and REACH affected, appropriate for applications without such regulatory constraints.

Selection between these parts should be based on the specific compliance requirements of the end application and regional market regulations.

Frequently Asked Questions (FAQ)

Q: Are CMF554K7000FKBF and CMF554K7000FKEK electrically interchangeable?

A: Yes. Both parts are identical in resistance value (4.7 kOhms), tolerance (±1%), power rating (0.5W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 175°C). They are direct functional equivalents.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts share identical physical dimensions (0.090" Dia x 0.240" L) and axial package configuration, allowing direct substitution in existing PCB layouts without design modification.

Q: What is the difference between the two part numbers?

A: The parts differ in regulatory compliance. CMF554K7000FKEK is ROHS3 compliant and REACH unaffected, while CMF554K7000FKBF is RoHS non-compliant and REACH affected. All electrical and mechanical specifications are identical.

Q: Which part should I specify for new designs?

A: Selection depends on application requirements. For applications requiring EU environmental compliance, specify CMF554K7000FKEK. For applications without such requirements, either part is acceptable based on availability.

Q: Are there inventory differences between these parts?

A: Yes. CMF554K7000FKBF has 1006 pieces in stock, while CMF554K7000FKEK has 12166 pieces in stock. Availability may influence sourcing decisions.
