Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMF553M0100GKEA is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Resistance value: 3.01 MOhms (exact match required)
• Power rating: 0.5W minimum (equal or higher acceptable)
• Tolerance: ±2% or better (tighter tolerance acceptable)
• Temperature coefficient: ±100ppm/°C or better (lower coefficient acceptable)
• Operating temperature range: -55°C to 175°C minimum coverage required

Mechanical Compatibility Parameters:

• Package type: Axial (required for through-hole board compatibility)
• Physical dimensions: 0.090" Dia x 0.240" L (2.29mm x 6.10mm) - exact match required
• Composition: Metal Film (required for performance characteristics)

Compliance Parameters:

• RoHS3 Compliant status required
• Active product status preferred for long-term availability

The CMF553M0100FHEB qualifies as a substitute based on matching all electrical, mechanical, and compliance requirements while offering improved tolerance (±1%) and lower temperature coefficient (±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the CMF553M0100GKEA and CMF553M0100FHEB are Active status components manufactured by Vishay Dale with full ROHS3 compliance. The CMF553M0100FHEB offers superior electrical performance through tighter tolerance (±1% versus ±2%) and improved temperature stability (±50ppm/°C versus ±100ppm/°C) while maintaining identical resistance value, power rating, operating temperature range, and physical dimensions. Selection between these parts depends on application requirements for tolerance and temperature coefficient performance. Both components are suitable for direct substitution in through-hole circuit board applications requiring 3.01 MOhms axial resistors.
