Substitute Part Grouping Explanation

Substitution eligibility for the CMF55147R00FKBF is determined by the following critical parameters:

• Resistance value: 147 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (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: 0.090" Dia x 0.240" L (exact match required)
• Series: CMF (exact match required)

The identified substitute part CMF55147R00FHEB meets all critical electrical and mechanical parameters. The primary differences are packaging format (Cut Tape versus Bulk) and compliance certifications (RoHS3 Compliant versus RoHS non-compliant), which do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The CMF55147R00FHEB serves as a direct functional equivalent to the CMF55147R00FKBF for circuit applications requiring 147 Ohm, 1/2W metal film resistors. Selection between these parts should be based on:

Packaging Requirements: The main part is supplied in Bulk packaging, while the substitute is supplied in Cut Tape format. Choose based on assembly process requirements and quantity needs.

Compliance Requirements: The CMF55147R00FHEB holds RoHS3 Compliant and REACH Unaffected certifications, making it suitable for applications with regulatory compliance mandates. The CMF55147R00FKBF is RoHS non-compliant and REACH Affected, appropriate for applications without such restrictions.

Temperature Coefficient: The CMF55147R00FHEB exhibits superior temperature stability at ±50ppm/°C compared to the main part at ±100ppm/°C. This difference is relevant only for applications requiring tighter temperature-dependent tolerance performance.

Both parts maintain identical electrical specifications, physical dimensions, and operating temperature ranges, ensuring mechanical and electrical interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can CMF55147R00FHEB replace CMF55147R00FKBF in existing designs?

A: Yes. Both parts are electrically and mechanically identical in resistance value, tolerance, power rating, composition, package type, and physical dimensions. The substitute can be used without circuit redesign.

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

A: Bulk packaging supplies loose components suitable for manual assembly or small-quantity applications. Cut Tape packaging provides components on continuous tape, optimized for automated pick-and-place assembly equipment. The choice depends on manufacturing process requirements.

Q: Does the temperature coefficient difference affect substitution?

A: The CMF55147R00FHEB has a lower temperature coefficient (±50ppm/°C versus ±100ppm/°C). This represents improved stability and does not prevent substitution. Applications sensitive to temperature-dependent resistance changes may benefit from the substitute part's superior performance.

Q: Are there compliance implications when switching between these parts?

A: Yes. The CMF55147R00FHEB is RoHS3 Compliant and REACH Unaffected, while the CMF55147R00FKBF is RoHS non-compliant and REACH Affected. Applications subject to RoHS or REACH regulations must use the compliant substitute part.

Q: Do both parts have the same physical footprint?

A: Yes. Both parts share identical dimensions of 0.090" Dia x 0.240" L (2.29mm x 6.10mm) and are packaged as axial components, ensuring identical PCB footprint and mounting compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on packaging format preference and regulatory requirements. For applications requiring RoHS3 compliance, the CMF55147R00FHEB is the appropriate choice. For applications without compliance mandates and requiring bulk packaging, the CMF55147R00FKBF is suitable.
