Substitute Part Grouping Explanation

Substitution eligibility for the CMF55412R00FHEK is determined by strict equivalence across the following parameters:

• Resistance value: 412 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 175°C
• Package type: Axial
• Physical dimensions: 0.090" Dia × 0.240" L
• Number of terminations: 2
• Features: Flame Retardant Coating, Moisture Resistant, Safety
• RoHS3 compliance

The identified substitute part CMF55412R00FHEB matches all electrical and mechanical parameters. The only difference is packaging format: the main part is supplied in Bulk packaging, while the substitute is supplied in Cut Tape (CT) packaging. Both parts share the same base product number (CMF55) and maintain identical performance characteristics across all specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both CMF55412R00FHEK and CMF55412R00FHEB are Active products with full RoHS3 compliance and identical electrical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

The CMF55412R00FHEK in Bulk packaging is suitable for high-volume manufacturing environments and applications requiring large quantity procurement. The CMF55412R00FHEB in Cut Tape (CT) packaging accommodates automated pick-and-place assembly processes and lower-volume production runs. Both parts satisfy identical performance criteria across all specified operating conditions and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can CMF55412R00FHEB be used as a direct replacement for CMF55412R00FHEK?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Bulk versus Cut Tape (CT). Substitution is valid for any application where the CMF55412R00FHEK is specified, provided the receiving equipment can accommodate the alternate packaging format.

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

A: Bulk packaging supplies components in loose form, typically for manual assembly or high-volume reel processing. Cut Tape (CT) packaging provides components on continuous tape, optimized for automated assembly equipment. Both formats contain the same component with identical specifications.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status and REACH compliance documentation. They share the same ECCN (EAR99) and HTSUS classification (8533.21.0090).

Q: What determines substitution eligibility for this resistor?

A: Substitution is valid when the following parameters match: resistance value (412 Ohms), tolerance (±1%), power rating (0.5W), composition (Metal Film), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 175°C), package type (Axial), physical dimensions (0.090" Dia × 0.240" L), and feature set (Flame Retardant Coating, Moisture Resistant, Safety).

Q: Can I substitute with a different resistance value or tolerance?

A: No. Substitution is restricted to parts with identical electrical specifications. Different resistance values or tolerances constitute a different component and require separate design validation.
