Engineering Selection Recommendations

For Direct Replacement (Identical Tolerance): CMF601M0000FHEK and CMF601M0000FKEK maintain the ±1% tolerance specification of the original part. CMF601M0000FHEK offers improved temperature coefficient stability (±50ppm/°C vs ±150ppm/°C). Both are active production parts with ROHS3 compliance.

For Upgraded Tolerance Performance: CMF601M0000BEEK and CMF601M0000BHEA provide ±0.1% tolerance, delivering tighter resistance accuracy. CMF601M0000BEEK offers the lowest temperature coefficient (±25ppm/°C) and is available in bulk packaging. CMF601M0000BHEA is supplied in cut tape format for automated assembly.

For Packaging Flexibility: CMF601M0000FKEB provides ±1% tolerance in cut tape packaging with high inventory availability (12208 pcs), suitable for high-volume automated production environments.

All substitute parts are active production items with ROHS3 compliance and identical mechanical compatibility with the original CMF601M0000FLEK.

Frequently Asked Questions (FAQ)

Q: Can CMF601M0000BEEK replace CMF601M0000FLEK in all applications? A: Yes. CMF601M0000BEEK is electrically and mechanically compatible. It provides superior tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±150ppm/°C), making it suitable for applications requiring higher precision.

Q: What is the difference between Bulk and Cut Tape (CT) packaging? A: Bulk packaging is suitable for manual assembly and small-volume applications. Cut Tape (CT) packaging is designed for automated pick-and-place assembly systems in high-volume production.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance status, ensuring compatibility with environmental and regulatory requirements.

Q: Can I use CMF601M0000FKEB as a direct substitute? A: Yes. CMF601M0000FKEB matches the ±1% tolerance and 1W power rating of the original part. The primary difference is cut tape packaging and a temperature coefficient of ±100ppm/°C instead of ±150ppm/°C.

Q: Which substitute offers the best temperature stability? A: CMF601M0000BEEK provides the lowest temperature coefficient at ±25ppm/°C, followed by CMF601M0000BHEA at ±50ppm/°C. Both feature ±0.1% tolerance for enhanced precision.

Q: Are physical dimensions identical across all substitute parts? A: Yes. All substitute parts maintain the same axial package dimensions of 0.145" Dia x 0.344" L (3.68mm x 8.74mm) and are mechanically interchangeable.
