Substitute Part Grouping Explanation

Substitution eligibility for the CMF554K7500FKBF is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.75 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W/1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 175°C (exact match required)
• Physical dimensions: 0.090" Dia x 0.240" L (exact match required)

The identified substitute part CMF554K7500FKEK meets all electrical and mechanical specifications. Differences in RoHS compliance status do not affect functional equivalence but may impact application requirements based on regulatory jurisdiction.

Parameter Comparison

Engineering Selection Recommendations

Both CMF554K7500FKBF and CMF554K7500FKEK are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements specific to the application jurisdiction. The CMF554K7500FKEK offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulations. The CMF554K7500FKBF remains available for applications where RoHS compliance is not mandated. Both parts carry REACH Affected status and EAR99 export classification. Inventory availability should be considered in procurement planning, with the main part currently offering higher stock levels.

Frequently Asked Questions (FAQ)

Q: Can CMF554K7500FKEK be used as a direct replacement for CMF554K7500FKBF?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. The primary difference is RoHS compliance status.

Q: What is the significance of the RoHS compliance difference?

A: RoHS3 compliance (CMF554K7500FKEK) is required for products sold in the European Union and certain other jurisdictions. Applications not subject to RoHS regulations can use either part. Verify your application's regulatory requirements before selection.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.090" diameter by 0.240" length (2.29mm x 6.10mm) and use identical axial through-hole package configuration, ensuring mechanical compatibility in PCB layouts.

Q: Do these parts have the same temperature operating range?

A: Yes. Both parts operate across -55°C to 175°C with identical temperature coefficient of ±100ppm/°C, ensuring equivalent performance across thermal conditions.

Q: Which part should I select if inventory is a consideration?

A: CMF554K7500FKBF currently has higher inventory (1055 units) compared to CMF554K7500FKEK (797 units). If regulatory compliance is not a constraint, the main part may offer better availability for immediate procurement.
