How Much Does Lam Research 666-068437-003 Cost in 2026?

Used units of the 666-068437-003 are priced at $270, with no variance between refurbished and as-is conditions due to standardized recalibration protocols. New units from Lam Research retail at $1,250, offering a 78.4% cost saving. Note: This discount applies only if the sensor’s fluoroptic probe has <5 years of operational lifespan remaining; probes degrade nonlinearly after 5 years, requiring premature replacement. Refurbished units include NIST-traceable calibration certificates, while used units may require revalidation.

666-068437-003 Specifications and Compatible Tools

This sensor operates within -20°C to 300°C, with ±0.2°C accuracy and 10ms response time. It draws 5V DC at 150mA and uses a 1kHz modulation frequency to reject RF noise. Compatible tools include:

Lam Centura Etch (models 666-068xxx, 2005–2012)
Lam Producer Etch (models 666-070xxx, 2010–2018)
Lam Symphony Etch (models 666-075xxx, 2008–2015)
Exclusion: Not compatible with Lam 300mm Symphony X (part 666-068437-005 uses a different optical interface).

What to Check Before Buying a Used 666-068437-003 in 2026

Fiber-optic probe integrity: Use 10x magnification to inspect for microcracks; reject if >2 cracks exist per 10cm length.
Signal noise testing: Connect to an oscilloscope; signal noise must stay below 5% of full scale at 1kHz.
Calibration drift: Compare against a NIST-traceable reference; deviation >±0.5°C invalidates accuracy.
Connector wear: Measure pin resistance with a multimeter; >0.1Ω indicates corrosion or arcing risk.
Lifespan assessment: Reject units with >8 years of operational history due to polymer coating delamination risks.

FAQ

Q: Is the 666-068437-003 repairable if the fluoroptic probe fails?
A: No. The probe is hermetically sealed; failure requires full assembly replacement.

Q: Does this sensor work with Applied Materials tools?
A: Only if retrofitted for AMAT’s legacy CentriCore platforms (2007–2010).
