Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF551K0200FKBF is determined by the following critical parameters:

• Resistance value: 1.02 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: Axial through-hole (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 CMF551K0200FHEB meets all critical electrical and mechanical parameters. Differences exist only in packaging format (Cut Tape versus Bulk), temperature coefficient specification, and regulatory compliance status. These differences do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CMF551K0200FKBF and CMF551K0200FHEB are functionally equivalent for circuit applications requiring a 1.02 kOhms ±1% metal film resistor at 0.5W power rating in axial package configuration.

Selection between these parts should be based on:

• Packaging requirements: CMF551K0200FKBF is supplied in Bulk format; CMF551K0200FHEB is supplied in Cut Tape (CT) format
• Regulatory compliance: CMF551K0200FHEB is ROHS3 Compliant and REACH Unaffected, while CMF551K0200FKBF is RoHS non-compliant and REACH Affected
• Temperature coefficient: CMF551K0200FHEB offers improved temperature stability at ±50ppm/°C compared to ±100ppm/°C for the main part
• Inventory availability: Selection may depend on current stock levels and supply chain requirements

Frequently Asked Questions (FAQ)

Q: Can CMF551K0200FHEB be used as a direct replacement for CMF551K0200FKBF?

A: Yes. Both parts are identical in electrical specifications (1.02 kOhms ±1%, 0.5W, metal film composition) and mechanical dimensions (0.090" Dia x 0.240" L axial package). They are functionally interchangeable in circuit applications.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies loose components, while Cut Tape (CT) packaging provides components on continuous tape suitable for automated assembly equipment. The electrical and mechanical properties of the resistor are identical; packaging format affects only handling and assembly processes.

Q: Does the temperature coefficient difference affect substitution?

A: The temperature coefficient difference (±100ppm/°C versus ±50ppm/°C) does not prevent substitution. CMF551K0200FHEB provides superior temperature stability. Substitution is valid unless the application specifically requires the ±100ppm/°C characteristic of the main part.

Q: Are there compliance implications when substituting these parts?

A: Yes. CMF551K0200FHEB is ROHS3 Compliant and REACH Unaffected, while CMF551K0200FKBF is RoHS non-compliant and REACH Affected. Applications subject to RoHS or REACH regulations should use CMF551K0200FHEB.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 175°C. The improved temperature coefficient of CMF551K0200FHEB may provide better performance stability across this range.
