Substitute Part Grouping Explanation
Substitution eligibility for the RCS2012F1650CS is determined by strict alignment of the following parameters:
Critical Matching Parameters:
- Resistance value: 165 Ohms
- Tolerance: ±1%
- Power rating: 0.125W (1/8W)
- Package: 0805 (2012 Metric)
- Composition: Thick Film
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C ~ 155°C
- RoHS compliance: ROHS3 Compliant
- Moisture sensitivity level: 1 (Unlimited)
All identified substitute parts meet these criteria. Variations in physical height dimensions and specific feature sets (such as automotive AEC-Q200 certification or anti-sulfur coating) do not disqualify substitution when all electrical and mechanical core parameters align.
