How Much Does Lam Research 839-440462-306 Cost in 2026?

Used units for 2026 are priced between $1,200–$2,800, depending on condition and provenance. Refurbished variants, with full OEM recalibration, range from $1,800–$3,200. These figures represent 30–40% savings versus new pricing (which exceeds $4,500 as of 2024). Critical caveat: parts from systems decommissioned before 2018 often show >15% erosion in electrode thickness, requiring laser reprofiling or rejection. Always verify service history for plasma exposure hours—components with >50k cumulative hours demand discounted rates due to dielectric degradation risks.
