Parameter Comparison

Engineering Selection Recommendations

CMF5568K100FKBF Selection Criteria:

• Applications requiring standard ±1% tolerance specifications
• Bulk packaging requirements for high-volume assembly operations
• Established designs with validated performance at ±100ppm/°C temperature coefficient

CMF5568K100DHR6 Selection Criteria:

• Applications requiring improved tolerance performance (±0.5%)
• Circuits sensitive to temperature coefficient drift, benefiting from ±50ppm/°C specification
• Automated assembly processes utilizing cut tape packaging format
• Higher inventory availability (1546 units versus 817 units)

Both parts maintain identical RoHS non-compliant status, REACH affected classification, and EAR99 ECCN designation. Selection between these parts depends on tolerance requirements, temperature stability demands, and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CMF5568K100DHR6 replace CMF5568K100FKBF in existing designs?

A: Yes. Both parts share identical resistance, power rating, package type, physical dimensions, and operating temperature range. The substitute offers tighter tolerance (±0.5% versus ±1%) and lower temperature coefficient (±50ppm/°C versus ±100ppm/°C), making it electrically compatible and functionally superior for most applications.

Q: What is the primary difference between these two parts?

A: The main differences are tolerance specification, temperature coefficient, and packaging format. CMF5568K100DHR6 provides improved electrical precision with ±0.5% tolerance and ±50ppm/°C temperature coefficient, while CMF5568K100FKBF offers standard ±1% tolerance with ±100ppm/°C temperature coefficient. Packaging differs between Bulk and Cut Tape formats.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.090" diameter × 0.240" length (2.29mm × 6.10mm) in axial configuration, ensuring identical PCB footprint and mechanical fit.

Q: Does packaging format affect electrical performance?

A: No. Bulk and Cut Tape packaging formats do not affect electrical characteristics. Selection depends on assembly process requirements and handling procedures.

Q: Are both parts currently in stock?

A: Yes. CMF5568K100FKBF has 817 units available, while CMF5568K100DHR6 has 1546 units in inventory.
