Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F6191CS is determined by the following critical parameters:

Electrical Specifications: Resistance value (6.19 kOhms), tolerance (±1%), and power rating (0.05W) must be identical. These parameters ensure functional equivalence in the circuit.

Package Compatibility: The 0201 (0603 Metric) package designation and physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) must match exactly to ensure mechanical fit on printed circuit boards and compatibility with automated assembly equipment.

Composition & Construction: Thick film construction is the specified technology for this component category.

Compliance & Environmental: ROHS3 compliance and MSL 1 rating are mandatory for equivalent substitution in regulated applications.

Temperature Performance: Operating temperature range must support the application's thermal requirements. The original part specifies -55°C to 125°C; substitute parts with extended upper temperature limits remain compatible.
