Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F4422CS is determined by the following critical parameters:

Electrical Specifications: Resistance value of 44.2 kOhms with ±1% tolerance is the primary electrical requirement. Power rating of 0.05W (1/20W) must be maintained or exceeded.

Mechanical Compatibility: Package designation 0201 (0603 Metric) with physical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm) ensures PCB layout compatibility.

Environmental & Compliance: RoHS3 compliance, MSL 1 rating, and REACH unaffected status are mandatory for equivalent substitution in regulated applications.

Composition & Construction: Thick film construction maintains performance characteristics across the specified operating temperature range.

The identified substitute CRCW020144K2FKED from Vishay Dale meets all critical parameters while offering extended operating temperature range (-55°C ~ 155°C) and improved temperature coefficient (±100ppm/°C versus ±250ppm/°C).
