Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F3830CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (383 Ohms), 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 format must be 2512 (6432 Metric) to ensure PCB footprint compatibility. Physical dimensions and termination count (2 terminations) must match or remain within acceptable assembly tolerances.

Regulatory Compliance: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are mandatory for substitution. REACH Unaffected status ensures regulatory alignment.

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

The CRCW2512383RFKEG from Vishay Dale satisfies all substitution criteria while adding automotive AEC-Q200 qualification, providing enhanced reliability for demanding applications.
