Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F8662CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (86.6 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) and number of terminations (2) ensure physical fit and circuit board integration without redesign.

Compliance & Environmental: RoHS3 compliance and MSL 1 rating confirm regulatory alignment and handling requirements.

Composition: Thick film construction maintains electrical performance characteristics consistent with the original design.

The identified substitute CRCW251286K6FKEG from Vishay Dale meets all specified parameters while adding automotive-grade AEC-Q200 qualification, providing enhanced reliability for demanding applications.
