Substitute Part Grouping Explanation

Substitution between CMF55133R00FKBF and CMF55133R00FHEB is based on the following allowed parameters:

• Resistance value: 133 Ohms (identical)
• Tolerance: ±1% (identical)
• Power rating: 0.5W / 1/2W (identical)
• Composition: Metal Film (identical)
• Package type: Axial (identical)
• Operating temperature range: -55°C to 175°C (identical)
• Physical dimensions: 0.090" Dia x 0.240" L (identical)
• Number of terminations: 2 (identical)
• Features: Flame Retardant Coating, Moisture Resistant, Safety (identical)

The primary differences between these parts are packaging format (Bulk versus Cut Tape) and compliance certifications, which do not affect electrical or mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both CMF55133R00FKBF and CMF55133R00FHEB are electrically and mechanically equivalent for circuit applications requiring a 133 Ohm, 1/2W metal film axial resistor. Selection between these parts should be based on:

• Packaging requirements: CMF55133R00FKBF is supplied in Bulk format; CMF55133R00FHEB is supplied in Cut Tape format
• Compliance mandates: CMF55133R00FHEB meets ROHS3 compliance and is REACH Unaffected, while CMF55133R00FKBF is RoHS non-compliant and REACH Affected
• Temperature coefficient precision: CMF55133R00FHEB offers ±50ppm/°C versus ±100ppm/°C for CMF55133R00FKBF
• Inventory availability: CMF55133R00FHEB has higher stock levels (2415 pieces versus 710 pieces)

Frequently Asked Questions (FAQ)

Q: Are CMF55133R00FKBF and CMF55133R00FHEB electrically interchangeable?

A: Yes. Both parts share identical resistance (133 Ohms), tolerance (±1%), power rating (0.5W), composition (Metal Film), operating temperature range (-55°C to 175°C), and physical dimensions (0.090" Dia x 0.240" L). They are electrically and mechanically 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 adhesive tape in carrier strips. Cut Tape format is typically used for automated assembly processes, while Bulk format is used for manual assembly or kit applications.

Q: Does the temperature coefficient difference affect substitution?

A: The temperature coefficient difference (±100ppm/°C versus ±50ppm/°C) does not prevent substitution. CMF55133R00FHEB offers tighter temperature stability, but both parts operate within the same temperature range and maintain the specified tolerance across the operating window.

Q: Which part should I select for RoHS-compliant applications?

A: CMF55133R00FHEB is ROHS3 Compliant and REACH Unaffected. CMF55133R00FKBF is RoHS non-compliant and REACH Affected. For applications requiring RoHS compliance, CMF55133R00FHEB is the appropriate selection.

Q: Can I use these parts interchangeably in existing designs?

A: Yes, provided your application does not have specific packaging format requirements or compliance mandates. Both parts are functionally equivalent and will perform identically in circuit operation.
