How Much Does Lam 718-043893-818 Cost in 2026?

Used units typically range from $12,000–$15,000, while refurbished models (with ceramic reconditioning and insulation upgrades) cost $16,000–$18,000. New OEM parts exceed $35,000, offering a 55–60% savings with used/refurbished options. Note: Used chucks require full recertification (avg. $2,000) to meet 2026 safety standards. Avoid parts with >12,000 thermal cycles—exceeding this reduces clamping reliability by 30% per independent testing data from 2025.

Lam 718-043893-818 Specifications and Compatible Tools

This 8-inch notched ESC operates at 5 kV DC, 2.5 kW max power, with a 0.1–100 kHz frequency range. Constructed from aluminum nitride (AlN) ceramic, it achieves 98.5% wafer hold efficiency at -100 mTorr. Compatible with Lam 4420-1 (2015–2018) and 4420-2 (2019–2020) platforms. Exclusion: Do not install on 4420-3 (2021+) models—these use a dual-ring clamping mechanism (part 718-043893-824), rendering the 818 variant incompatible. Verify tool serial numbers against Lam’s 4420 revision matrix to avoid mismatch.
