Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF0805FG1M21 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.21 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The RMCF0805FT1M21 qualifies as a direct substitute because it maintains identical electrical and mechanical specifications across all parameters listed above. Both parts belong to the same RMCF series from Stackpole Electronics Inc and are functionally interchangeable in automotive applications.
