Substitute Part Grouping Explanation

Substitution eligibility for the CMF554K7000FHBF 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: ±50ppm/°C
• Operating temperature range: -55°C to 175°C
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Termination count: 2

The CMF554K7000FHEK meets all electrical and mechanical requirements for direct substitution. Differences in RoHS compliance status and REACH classification do not affect functional equivalence but may influence procurement decisions based on regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both CMF554K7000FHBF and CMF554K7000FHEK are functionally equivalent for applications requiring 4.7 kOhms ±1% metal film axial resistors with 0.5W power rating. Selection between these parts should be based on regulatory compliance requirements and supply chain considerations.

The CMF554K7000FHEK offers ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to European Union environmental regulations. The CMF554K7000FHBF remains available for applications where RoHS compliance is not mandated.

Inventory availability differs significantly, with CMF554K7000FHEK offering substantially higher stock levels (21,986 units versus 1,123 units), which may influence lead time and procurement strategy.

Frequently Asked Questions (FAQ)

Q: Can CMF554K7000FHEK be used as a direct replacement for CMF554K7000FHBF?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 4.7 kOhms resistance, ±1% tolerance, 0.5W power rating, metal film composition, axial package, and identical physical dimensions. The primary differences are compliance certifications and inventory levels.

Q: What is the difference in RoHS compliance between these parts?

A: CMF554K7000FHBF is RoHS non-compliant, while CMF554K7000FHEK is ROHS3 compliant. This distinction affects suitability for applications subject to EU environmental directives but does not impact electrical or mechanical performance.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions of 0.090" diameter by 0.240" length (2.29mm x 6.10mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What does REACH Affected versus REACH Unaffected mean?

A: REACH Affected indicates the part may contain substances of concern under EU REACH regulations, while REACH Unaffected indicates compliance with REACH requirements. Selection depends on regulatory obligations applicable to the end application.

Q: Which part should be selected for new designs?

A: Selection should be based on regulatory requirements of the target market and application. For EU-regulated applications, CMF554K7000FHEK is the appropriate choice due to ROHS3 compliance and REACH unaffected status.
