Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMF55200R00FKBF39 are identified through strict parametric matching across the following criteria:

• Electrical Parameters: Resistance value (200 Ohms), tolerance (±1%), and power rating (0.5W) must be identical
• Composition & Construction: Metal film composition with equivalent thermal and electrical characteristics
• Mechanical Compatibility: Axial package format with matching physical dimensions (0.090" Dia × 0.240" L)
• Environmental Specifications: Temperature coefficient (±100ppm/°C) and operating range (-55°C to 175°C) must align
• Termination Configuration: Two-terminal axial lead configuration for direct PCB mounting compatibility

The CMF55 series base product number ensures consistency within the Vishay Dale product family. Substitutes maintain identical functional performance while potentially differing in compliance certifications and packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

Both the CMF55200R00FKBF39 and CMF55200R00FKEK are functionally equivalent 200 Ohm metal film resistors with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

CMF55200R00FKBF39 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material sourcing is permissible.

CMF55200R00FKEK is the appropriate selection for designs requiring ROHS3 compliance and REACH-unaffected component sourcing. This variant provides enhanced regulatory alignment for markets with strict environmental standards.

Both parts maintain Active product status and are available in production quantities. The choice between them does not affect circuit performance, thermal characteristics, or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can CMF55200R00FKEK be used as a direct replacement for CMF55200R00FKBF39?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (200 Ohms), tolerance (±1%), power rating (0.5W), temperature coefficient (±100ppm/°C), and axial package dimensions. The primary difference is regulatory compliance status.

Q: What is the difference between these two part numbers?

A: The CMF55200R00FKEK variant is ROHS3 compliant and REACH unaffected, while the CMF55200R00FKBF39 is RoHS non-compliant and REACH affected. All electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions of 0.090" diameter × 0.240" length (2.29mm × 6.10mm), ensuring identical PCB footprint and mounting compatibility.

Q: Which part should I specify for new designs?

A: Selection depends on your regulatory requirements. For designs requiring environmental compliance certifications, specify CMF55200R00FKEK. For applications without compliance constraints, either part is functionally equivalent.

Q: Is inventory availability a factor in substitution?

A: Both parts are in active production with available inventory. CMF55200R00FKEK currently has higher stock levels (1568 Pcs vs. 938 Pcs), which may influence lead time considerations.
