Condition Options and Lead Time

Conditions we've observed on the market for 716-031257-739: new – open box. Availability in a specific condition changes week to week.

Lead time depends on where the part is sourced; we confirm it with the quote, and parts already on a partner's shelf ship faster. Every unit is inspected before shipment.

Inspect ceramic edge rings carefully for chips, cracks, and plasma erosion along the inner edge and top surface, as even minor damage can affect process uniformity and risk wafer contamination.
