Parameter Comparison

Engineering Selection Recommendations

CMF553M0100GNEA Selection Criteria:

• Applications requiring ±2% tolerance specification
• Standard temperature coefficient performance acceptable at ±200ppm/°C
• Tape & Reel packaging format for automated assembly processes
• Active production status with established supply chain

CMF553M0100FHEB Selection Criteria:

• Applications requiring improved tolerance specification at ±1%
• Enhanced temperature stability with ±50ppm/°C coefficient
• Cut Tape packaging format for manual or selective assembly operations
• Active production status with higher inventory availability (1584 units)
• RoHS3 compliance, REACH unaffected status, and EAR99 classification

Both parts maintain identical electrical performance for resistance value and power rating. The substitute part CMF553M0100FHEB provides superior tolerance and temperature coefficient characteristics while maintaining full compatibility with the axial package footprint and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can CMF553M0100FHEB directly replace CMF553M0100GNEA in existing designs?

A: Yes. Both parts share identical resistance value (3.01 MOhms), power rating (0.5W), physical dimensions (0.090" Dia x 0.240" L), and operating temperature range (-55°C to 175°C). The substitute part offers improved tolerance (±1% versus ±2%) and temperature coefficient (±50ppm/°C versus ±200ppm/°C), making it functionally compatible for all applications where the main part is specified.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) packaging provides components on tape segments cut to specific lengths, suitable for lower-volume or manual assembly operations. Both formats contain identical components with no electrical or mechanical differences.

Q: Does the improved tolerance of CMF553M0100FHEB affect circuit performance?

A: The ±1% tolerance of the substitute part is tighter than the ±2% tolerance of the main part. This provides improved resistance accuracy, which benefits applications sensitive to component value variation. The substitute part will not negatively impact circuits designed for the main part's ±2% tolerance specification.

Q: Are there any compliance or certification differences between these parts?

A: CMF553M0100FHEB includes documented RoHS3 compliance, REACH unaffected status, and EAR99 classification. Both parts share identical composition, features (flame retardant coating, moisture resistant, safety), and operating temperature range. Compliance documentation should be verified against specific application requirements.

Q: What is the significance of the temperature coefficient difference?

A: The main part CMF553M0100GNEA has a temperature coefficient of ±200ppm/°C, while the substitute CMF553M0100FHEB has ±50ppm/°C. Lower temperature coefficient indicates better resistance stability across the operating temperature range (-55°C to 175°C). Applications operating across wide temperature ranges benefit from the improved stability of the substitute part.
