CRCW0805909KFKEAC Equivalent & Substitute Parts
Part Overview
The CRCW0805909KFKEAC is a 909 kOhms ±1% 0.125W chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This thick film resistor is currently in active production status. Substitute parts are necessary when the primary part becomes unavailable due to supply constraints, inventory depletion, or when design requirements call for alternative manufacturing sources with enhanced features such as automotive qualification or moisture resistance.

Substitute Part Grouping Explanation
Substitution eligibility for the CRCW0805909KFKEAC is determined by strict equivalence across the following parameters: resistance value (909 kOhms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All substitute parts listed meet these core electrical and mechanical specifications. Physical dimensions remain consistent across all qualified substitutes within the 0805 package standard. RoHS3 compliance and MSL Level 1 rating are maintained across all alternatives. Substitute parts may include enhanced features such as automotive AEC-Q200 qualification or moisture-resistant construction, which represent functional upgrades rather than deviations from base specifications.
