Substitute Part Grouping Explanation

Substitute parts for the RC1005F1433CS are classified based on strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Resistance value: 143 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Package / Case: 0402 (1005 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature Coefficient: ±100ppm/°C (exact match required)
Operating Temperature Range: -55°C ~ 155°C (exact match required)
Number of Terminations: 2 (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Consideration:

Power Rating: 0.063W (1/16W) is the baseline specification. Parts rated at 0.1W (1/10W) or higher are acceptable upgrades as they provide equal or greater power dissipation capability within the same package footprint.

All identified substitute parts meet these criteria and are classified as Direct, Upgrade, or Similar based on their exact parameter alignment with the main part.
