How Much Does 716-203945-001 Cost in 2026?

Used prices for 716-203945-001 in 2026 range from $12,500 to $18,000, depending on RF-hour count and condition. Refurbished units command $2,000–$3,500 more, reflecting full factory rework. This represents 50–70% savings vs. new OEM list prices, which hover around $25,000–$35,000. Units with >40,000 RF-hours are prioritized for 2026 buyers, as lower-hour parts may lack wear resistance. Note that 2026 pricing reflects a stable market, with no major supply chain disruptions affecting availability. Buyers should verify exact RF-hour metrics and confirm whether the unit includes original calibration certificates, as these factors directly impact 2026 value.

716-203945-001 Specifications and Compatible Tools

The 716-203945-001 is a bipolar alumina electrostatic chuck (ESC) rated for 300mm wafer handling. Key specs include 1,200V DC voltage, 10A RMS current, and 150W power output. It operates at 200kHz frequency and supports flow rates up to 150 SCCM. Compatible with Lam 2300 Flex E (model 2300-1000, 2018–2021) and Lam 2300 Kiyo E (model 2300-2000, 2020–2023). Avoid using with 716-203945-002, as its higher voltage rating (1,500V) may cause overcurrent faults. Always verify tool firmware versions—2026 compatibility requires firmware V2.1.2 or later.

What to Check Before Buying a Used 716-203945-001 in 2026

Confirm RF-hour count is >40,000 using the tool’s maintenance log. Units below this threshold may lack 2026 wear resistance.
Test insulation resistance with a megohmmeter: minimum 100 MΩ at 500V DC. Lower readings indicate potential arcing risks.
Inspect for surface cracks under 5x magnification; reject any with visible damage.
Use a thermal imaging camera to check for hotspots exceeding 50°C during 2026 load tests.
Verify the chuck’s lifecycle year (2015–2020) to ensure it meets 2026 serviceability standards.

FAQ

Q: Is 716-203945-001 better than 716-203945-002 for 2026 applications?
A: No. The 716-203945-001 is rated for 1,200V DC, while 716-203945-002 operates at 1,500V. The latter is unsuitable for 2026 Flex E tools due to overcurrent risks.

Q: Can 716-203945-001 be used with Lam 2300 Kiyo E in 2026?
A: Yes, but only if firmware is updated to V2.1.2. Older versions (pre-2023) may cause compatibility errors.

Q: How does 716-203945-001 compare to OEM parts in 2026?
A: It offers 50–70% cost savings over new OEM units, with identical performance metrics. However, 2026 warranty terms differ—used parts lack manufacturer guarantees.

Q: What’s the lead time for sourcing 716-203945-001 in 2026?
A: 2–4 weeks after sourcing confirmation, as per 2026 supplier lead times. Expedited shipping may add $1,000–$2,000.
