Substitute Part Grouping Explanation

Substitution between CMF50464R00FKEA and CMF50464R00FHEB is based on the following allowed parameters:

• Resistance value: 464 Ohms (identical)
• Tolerance: ±1% (identical)
• Power rating: 0.25W, 1/4W (identical)
• Composition: Metal Film (identical)
• Package type: Axial (identical)
• Operating temperature range: -55°C to 175°C (identical)
• Physical dimensions: 0.065" Dia x 0.150" L (identical)
• Number of terminations: 2 (identical)
• RoHS3 compliance: Both compliant
• ECCN and HTSUS classifications: Identical

The primary difference between these parts is the packaging format: CMF50464R00FKEA is supplied in Tape & Reel (TR) format, while CMF50464R00FHEB is supplied in Cut Tape (CT) format. Both parts share the same base product number (CMF50) and maintain equivalent electrical performance within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both CMF50464R00FKEA and CMF50464R00FHEB are Active status products with full RoHS3 compliance. Selection between these parts should be based on packaging requirements and supply chain considerations:

CMF50464R00FKEA in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required.

CMF50464R00FHEB in Cut Tape format accommodates lower-volume applications, manual assembly processes, or situations where individual component handling is preferred.

The CMF50464R00FHEB variant offers improved temperature coefficient performance (±50ppm/°C versus ±100ppm/°C), which may be advantageous in applications with stringent thermal stability requirements. Both parts maintain identical electrical specifications for resistance value, tolerance, and power rating across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CMF50464R00FHEB replace CMF50464R00FKEA in existing designs?

A: Yes. Both parts share identical electrical specifications (464 Ohms ±1%, 0.25W), composition (metal film), and physical dimensions (0.065" Dia x 0.150" L). The substitution is valid from an electrical and mechanical standpoint. Packaging format differences (Tape & Reel versus Cut Tape) affect only the supply and assembly process, not circuit performance.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place equipment. Cut Tape (CT) packaging provides components in tape strips of specified lengths, typically used for manual assembly or lower-volume production runs.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant. CMF50464R00FKEA is REACH Affected, while CMF50464R00FHEB is REACH Unaffected. Both carry identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Q: Does the temperature coefficient difference affect substitution?

A: The temperature coefficient difference (±100ppm/°C for CMF50464R00FKEA versus ±50ppm/°C for CMF50464R00FHEB) indicates improved thermal stability in the substitute part. This represents a performance enhancement rather than a limitation, making CMF50464R00FHEB suitable for applications with tighter thermal requirements.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 175°C, providing identical thermal operating boundaries for circuit design purposes.
