Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF55165R00FKBF is determined by the following critical parameters:

• Electrical Parameters: Resistance value (165 Ohms), tolerance (±1%), and power rating (0.5W) must remain identical
• Physical Parameters: Package type (Axial), dimensions (0.090" Dia x 0.240" L), and termination count (2) must match
• Material Composition: Metal film construction with flame retardant coating and moisture resistance
• Operating Range: Temperature coefficient and operating temperature range (-55°C to 175°C) must be maintained or improved
• Packaging Format: Bulk and Cut Tape (CT) packaging formats are interchangeable for component-level selection

The identified substitute CMF55165R00FHEB maintains all critical electrical and mechanical parameters while offering improved temperature coefficient performance and enhanced compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both CMF55165R00FKBF and CMF55165R00FHEB are Active products from Vishay Dale's CMF series and are electrically and mechanically interchangeable at the component level. Selection between these parts should be based on the following criteria:

CMF55165R00FKBF is suitable for applications where bulk packaging is preferred and RoHS/REACH compliance is not a design requirement.

CMF55165R00FHEB is the preferred selection for designs requiring ROHS3 compliance and REACH unaffected status. This substitute also provides improved temperature coefficient performance (±50ppm/°C versus ±100ppm/°C), which may benefit applications with stringent thermal stability requirements. Cut Tape packaging is appropriate for automated assembly processes and component-level procurement workflows.

Frequently Asked Questions (FAQ)

Q: Are CMF55165R00FKBF and CMF55165R00FHEB electrically identical?

A: Yes. Both parts have identical resistance (165 Ohms), tolerance (±1%), power rating (0.5W), composition (metal film), and operating temperature range (-55°C to 175°C). The substitute offers improved temperature coefficient performance.

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

A: Bulk packaging is suitable for manual assembly and stock management. Cut Tape (CT) packaging is designed for automated pick-and-place assembly equipment and component-level procurement. Both formats contain the same component.

Q: Can CMF55165R00FHEB replace CMF55165R00FKBF in existing designs?

A: Yes. The substitute maintains all critical electrical and mechanical parameters, including resistance, tolerance, power rating, dimensions, and operating temperature range. Physical board layout and footprint compatibility are identical.

Q: Why does CMF55165R00FHEB have a lower temperature coefficient?

A: The substitute part (±50ppm/°C) exhibits superior temperature stability compared to the main part (±100ppm/°C). This represents an improvement in performance characteristics and does not affect substitution compatibility.

Q: What compliance differences exist between these parts?

A: CMF55165R00FKBF is RoHS non-compliant and REACH Affected. CMF55165R00FHEB is ROHS3 Compliant and REACH Unaffected. Selection depends on regulatory requirements for the end application.
