Substitute Part Grouping Explanation

Substitution eligibility for the MBA02040C1802FC100 is determined by strict equivalence across the following parameters:

• Resistance value: 18 kOhms
• Tolerance: ±1%
• Power rating: 0.4W
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Package configuration: Axial leads
• Physical dimensions: 0.063" Dia x 0.142" L (1.60mm x 3.60mm)
• Automotive qualification: AEC-Q200
• Regulatory compliance: ROHS3 Compliant

The identified substitute part maintains complete parametric equivalence across all electrical and mechanical specifications. Substitution is valid only when all parameters match exactly.

Parameter Comparison

Engineering Selection Recommendations

Both the MBA02040C1802FC100 and MBA02040C1802FCT00 are active production components manufactured by Vishay Beyschlag/Draloric/BC Components with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences.

The MBA02040C1802FCT00 offers higher inventory availability at 4104 units compared to 1910 units for the MBA02040C1802FC100. Both components maintain ROHS3 compliance, REACH unaffected status, and automotive AEC-Q200 qualification. Either part is suitable for applications requiring 18 kOhms ±1% 0.4W metal film resistors in axial configuration across the -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can MBA02040C1802FCT00 be used as a direct replacement for MBA02040C1802FC100?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package type, and physical dimensions. Both meet AEC-Q200 automotive qualification and ROHS3 compliance requirements.

Q: Are there differences in reliability or performance between these two part numbers?

A: No. Both components are manufactured by the same supplier using identical specifications. Differences in part numbering reflect packaging or distribution variations only, not performance characteristics.

Q: What determines substitution eligibility for this resistor?

A: Substitution is valid only when all parameters match exactly: 18 kOhms resistance, ±1% tolerance, 0.4W power rating, metal film composition, ±50ppm/°C temperature coefficient, -55°C to 155°C operating range, axial package configuration, 0.063" Dia x 0.142" L dimensions, AEC-Q200 qualification, and ROHS3 compliance.

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

A: No. Resistance value and tolerance are critical electrical parameters. Any deviation from 18 kOhms ±1% constitutes a different component and is not a valid substitute.

Q: Are both parts suitable for automotive applications?

A: Yes. Both MBA02040C1802FC100 and MBA02040C1802FCT00 carry AEC-Q200 automotive qualification and are suitable for automotive circuit applications within the specified operating temperature range.
