Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F4643CS are classified based on strict electrical and mechanical parameter matching. All identified substitutes maintain the following core specifications: 464 kOhms resistance value, ±1% tolerance, 0402 (1005 Metric) package dimensions, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating temperature range. Substitution categories are defined as follows:

Direct Substitutes share identical electrical ratings (0.063W power), mechanical dimensions, and packaging format with the main part. These parts are pin-compatible and functionally equivalent for direct board-level replacement.

Upgrade Substitutes provide higher power rating (0.1W versus 0.063W) while maintaining all other electrical and mechanical parameters. These parts offer enhanced thermal performance and are suitable for applications requiring additional power dissipation margin.

Similar Substitutes include automotive-grade AEC-Q200 qualified parts or enhanced moisture resistance features while maintaining core electrical specifications and package compatibility. These parts are suitable for applications with automotive or enhanced reliability requirements.

All substitute parts comply with ROHS3 standards, maintain MSL 1 rating, and operate within the specified temperature range.
