How Much Does 853-011802-001 Cost in 2026?

Used units range from $12,000–$15,000, while refurbished versions cost $18,000–$22,000. New OEM parts exceed $45,000, offering ~60–70% savings with used/refurbished options. Note: Used parts with ceramic layer thickness below 0.8mm (measured via laser profilometry) must be rejected due to plasma instability risks. Refurbished units include recalibrated RF matching networks and replaced cooling channels. Availability is limited to pre-2015 production batches; post-2015 variants use a different electrode geometry (853-011802-002).

853-011802-001 Specifications and Compatible Tools

Key specs: 1,600W RF power handling, 13.56MHz frequency, 2.5kV max voltage, and -5°C to 150°C operating temp range. Compatible with Lam 2300 Versys models P1–P5 (2008–2015 production). Exclusion: 2300 Versys MXE (Rev. C) systems using part 853-011802-002—installing this part will cause RF arcing due to mismatched impedance profiles. Verify tool’s RF bias generator model (LAM-3200B or LAM-3200C) before purchase.

What to Check Before Buying a Used 853-011802-001 in 2026

Ceramic layer thickness: Use a laser profilometer; reject if <0.8mm.
RF connector resistance: Measure with a multimeter; >0.1Ω indicates degraded contacts.
Cooling channel blockage: Pressure-test at 10psi for 5 minutes; >10% flow loss invalidates part.
Surface cracks: Inspect under UV light; any cracks >0.2mm require replacement.
Service history: Reject parts not replaced in the last 5 years (per Lam’s 7-year lifecycle policy).

FAQ

Q: Is used 853-011802-001 reliable for high-volume production?
A: Yes, if ceramic thickness and cooling channels meet thresholds. Refurbished units are recommended for 24/7 operations.

Q: Does 853-011802-001 fit 2300 Versys MXE tools?
A: No. MXE variants require 853-011802-002.

Q: How to test electrode uniformity?
A: Use a plasma uniformity scanner (e.g., LAM-UPS-300) at 1,000W; deviation >±8% requires recalibration.

Q: Used vs. refurbished: which is better?
A: Refurbished includes new cooling channels and recalibration. Used parts require in-house testing.
