Substitute Part Grouping Explanation

Substitution eligibility for the CMF601K5000FHEB is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.5 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 175°C
• Package configuration: Axial
• Physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant

The identified substitute part CMF601K5000FHEK meets all electrical and mechanical specifications. The primary difference is packaging format: the main part is supplied in tape and reel (TR) configuration, while the substitute is supplied in bulk packaging. Both parts share identical electrical characteristics, physical dimensions, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both CMF601K5000FHEB and CMF601K5000FHEK are active production parts with identical electrical specifications and ROHS3 compliance. Selection between these parts should be based on packaging requirements and inventory availability.

The CMF601K5000FHEB in tape and reel packaging is suitable for automated assembly processes requiring continuous component feeding. The CMF601K5000FHEK in bulk packaging is appropriate for manual assembly, kit builds, or applications where tape and reel format is not required. Both parts maintain equivalent performance across all operating conditions within the specified temperature range of -55°C to 175°C.

Frequently Asked Questions (FAQ)

Q: Can CMF601K5000FHEK be used as a direct replacement for CMF601K5000FHEB?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: tape and reel versus bulk. Substitution is valid for any application where the component packaging method does not impose constraints.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical resistance value (1.5 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 175°C).

Q: What is the significance of the packaging difference?

A: Tape and reel packaging (FHEB) is designed for automated pick-and-place assembly equipment. Bulk packaging (FHEK) is supplied without tape or reel and is typically used for manual assembly or component kits. The electrical and physical characteristics of the resistor itself are unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both CMF601K5000FHEB and CMF601K5000FHEK are ROHS3 compliant.

Q: Which part should I select if inventory is a concern?

A: CMF601K5000FHEK has higher current inventory (7425 units) compared to CMF601K5000FHEB (619 units). If packaging format permits, the bulk variant offers greater availability.
