Substitute Part Grouping Explanation

Substitution eligibility for the CMF604R7500FLEK is determined by the following critical parameters:

  • Resistance value: 4.75 Ohms (exact match required)
  • Tolerance: ±1% (exact match required)
  • Power rating: 1W (exact match required)
  • Composition: Metal Film (exact match required)
  • Package type: Axial (exact match required)
  • Operating temperature range: -55°C to 175°C (exact match required)
  • Physical dimensions: 0.145" Dia x 0.344" L (exact match required)
  • Regulatory compliance: ROHS3 Compliant (exact match required)

The identified substitute part CMF604R7500FKEB meets all critical electrical and mechanical parameters. The primary difference is packaging format: the main part is supplied in bulk packaging, while the substitute is supplied in cut tape (CT) format. Both parts are manufactured by Vishay Dale within the CMF series and maintain identical component specifications.

Engineering Selection Recommendations

Both CMF604R7500FLEK and CMF604R7500FKEB are active production components manufactured by Vishay Dale with identical electrical specifications and physical dimensions. Selection between these parts should be based on packaging requirements:

  • CMF604R7500FLEK: Bulk packaging format suitable for high-volume manufacturing or inventory consolidation
  • CMF604R7500FKEB: Cut tape packaging format suitable for automated assembly processes and component-level inventory management

Both parts maintain ROHS3 compliance and EAR99 export classification. The temperature coefficient difference (±150ppm/°C versus ±100ppm/°C) reflects manufacturing variance within the CMF series but does not affect functional equivalence for standard applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are CMF604R7500FLEK and CMF604R7500FKEB electrically identical?

A: Yes. Both parts have identical resistance value (4.75 Ohms), tolerance (±1%), power rating (1W), composition (metal film), and operating temperature range (-55°C to 175°C). The parts are functionally equivalent for circuit applications.

Q: What is the primary difference between these two parts?

A: The primary difference is packaging format. CMF604R7500FLEK is supplied in bulk packaging, while CMF604R7500FKEB is supplied in cut tape (CT) format. Physical component dimensions are identical.

Q: Can CMF604R7500FKEB replace CMF604R7500FLEK in existing designs?

A: Yes. The cut tape packaged CMF604R7500FKEB is a direct substitute for the bulk packaged CMF604R7500FLEK. No circuit modifications or design changes are required.

Q: Are both parts RoHS compliant?

A: Yes. Both CMF604R7500FLEK and CMF604R7500FKEB are ROHS3 compliant.

Q: What is the temperature coefficient difference between these parts?

A: CMF604R7500FLEK has a temperature coefficient of ±150ppm/°C, while CMF604R7500FKEB has ±100ppm/°C. Both operate within the same temperature range (-55°C to 175°C) and maintain specified tolerance across this range.

Q: Which part should be selected for automated assembly?

A: CMF604R7500FKEB in cut tape format is optimized for automated pick-and-place assembly processes. CMF604R7500FLEK in bulk format is suitable for manual assembly or bulk component handling.
