Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF55215R00FKBF is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Resistance value: 215 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film

Mechanical Parameters (Must Match):

• Package type: Axial
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm)
• Number of terminations: 2

Environmental Parameters (Must Match):

• Operating temperature range: -55°C to 175°C
• Features: Flame retardant coating, moisture resistant

Variable Parameters (Allowed to Differ):

• Packaging format (Bulk vs. Cut Tape)
• Temperature coefficient
• RoHS compliance status
• REACH compliance status

The CMF55215R00FHEB qualifies as a direct substitute based on matching all critical electrical, mechanical, and environmental parameters. Differences in packaging format and compliance certifications do not affect functional interchangeability in circuit applications.

Engineering Selection Recommendations

CMF55215R00FKBF (Bulk Packaging): Select this part number when bulk packaging format is required for manufacturing processes or inventory management. This configuration is suitable for high-volume assembly operations where tape-and-reel handling is not necessary.

CMF55215R00FHEB (Cut Tape Packaging): Select this part number when Cut Tape packaging format is required for automated pick-and-place assembly or when ROHS3 compliance is mandated by design specifications or customer requirements. This variant also provides improved temperature coefficient performance (±50ppm/°C vs. ±100ppm/°C), which may be beneficial for applications requiring tighter thermal stability.

Both part numbers are manufactured by Vishay Dale and maintain Active product status. Selection between these substitutes should be based on packaging requirements, compliance certifications needed for the end application, and thermal stability specifications.

Frequently Asked Questions (FAQ)

Q: Can CMF55215R00FHEB replace CMF55215R00FKBF in existing circuit designs?

A: Yes. Both parts are electrically and mechanically identical in all critical parameters: 215 Ohm resistance, ±1% tolerance, 0.5W power rating, metal film composition, axial package, and identical physical dimensions. The substitute is functionally interchangeable for circuit operation.

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

A: Bulk packaging supplies loose components in quantity, suitable for manual assembly or high-volume bin storage. Cut Tape packaging supplies components on continuous tape in individual pockets, optimized for automated assembly equipment and component feeders.

Q: Does the temperature coefficient difference affect substitution compatibility?

A: The CMF55215R00FHEB features a tighter temperature coefficient (±50ppm/°C) compared to the CMF55215R00FKBF (±100ppm/°C). This represents improved thermal stability and does not prevent substitution; it may provide enhanced performance in temperature-sensitive applications.

Q: Are there compliance differences between these part numbers?

A: Yes. The CMF55215R00FHEB is ROHS3 compliant and REACH unaffected, while the CMF55215R00FKBF is RoHS non-compliant and REACH affected. If your application or customer requirements mandate RoHS3 compliance, the CMF55215R00FHEB is the appropriate selection.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes, provided your assembly process supports the packaging format of the selected part number. Both components have identical footprints and lead configurations, allowing direct substitution at the board level.
