Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4642CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (46.4 kOhms), tolerance (±1%), and power rating (1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (2512 / 6432 Metric), physical dimensions (0.248" L x 0.126" W), and termination count (2) ensure physical fit and soldering compatibility.

Compliance & Quality: RoHS3 compliance and MSL 1 rating are mandatory for equivalent substitution. Product status must be Active.

Composition: Thick film construction is required to maintain electrical characteristics and reliability performance.

The identified substitute CRCW251246K4FKEG from Vishay Dale meets all specified parameters while adding automotive-grade AEC-Q200 qualification, representing an enhanced equivalent option.
