Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF601K5000FLEB is determined by the following criteria:

• Identical resistance value: 1.5 kOhms
• Identical tolerance: ±1%
• Identical power rating: 1W
• Identical composition: Metal Film
• Identical package type: Axial
• Identical physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Identical operating temperature range: -55°C to 175°C
• Same base product number: CMF60
• Active product status
• RoHS3 compliance

The CMF601K5000FHEK meets all substitution criteria and is classified as an upgrade variant within the CMF series, differing only in packaging format (Bulk versus Tape & Reel) and temperature coefficient specification.

Parameter Comparison

Engineering Selection Recommendations

Both CMF601K5000FLEB and CMF601K5000FHEK are active Vishay Dale products with ROHS3 compliance. Selection between these parts is based on packaging and supply requirements rather than electrical performance.

The CMF601K5000FLEB is supplied in Tape & Reel format, suitable for automated assembly processes. The CMF601K5000FHEK is supplied in Bulk packaging and offers higher inventory availability (7425 units versus 1109 units). Both parts maintain identical electrical specifications, mechanical compatibility, and environmental ratings.

The CMF601K5000FHEK exhibits a superior temperature coefficient specification (±50ppm/°C versus ±150ppm/°C), providing enhanced stability across the operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CMF601K5000FHEK replace CMF601K5000FLEB in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. The primary difference is packaging format (Bulk versus Tape & Reel) and temperature coefficient. Axial package dimensions and all electrical parameters are identical.

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

A: Tape & Reel packaging is optimized for automated pick-and-place assembly equipment. Bulk packaging is suitable for manual assembly or alternative handling methods. Both formats contain the same component.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant. The CMF601K5000FHEK is REACH Unaffected, while the CMF601K5000FLEB is REACH Affected. Both carry EAR99 export classification.

Q: Does the temperature coefficient difference affect substitution eligibility?

A: The CMF601K5000FHEK temperature coefficient (±50ppm/°C) is superior to the CMF601K5000FLEB (±150ppm/°C). This represents an improvement in thermal stability and does not restrict substitution.

Q: What are the physical dimensions for PCB layout planning?

A: Both parts measure 0.145" diameter by 0.344" length (3.68mm x 8.74mm). Axial package orientation requires linear PCB footprint spacing.
