Lifecycle: obsolete, sourced against an RFQ
ILS1B571S1189 is a Schneider Electric Lexium integrated stepper drive that the manufacturer lists as obsolete, so the channel is independent distribution rather than factory-direct ordering. For a packaging-line OEM running this part on the BOM, that means last-time-buy stock has already closed and any production volume now flows through surplus or broker inventory — quoted per RFQ against available lot quantities, not against a current production schedule.
What the record shows on status
The internal lifecycle field on this order code carries a 'current' label, but the authoritative productStatus entry from the manufacturer marks ILS1B571S1189 as obsolete — the official status is the operative one for procurement decisions and BOM continuity planning.
What the part is, in the line
ILS1B571S1189 sits in the Lexium integrated-drive family from Schneider Electric — a stepper motor / drive combination used where a compact, point-to-point motion axis needs a single integrated package rather than a separate drive and motor pair. That integration is the value on the BOM: one order code covers the motor, the drive electronics, and the feedback loop, which simplifies the panel layout and cuts the wiring between cabinet and machine frame — at the cost of a sealed, non-separable unit when the drive stage fails.
Sourcing posture for an obsolete MPN
Sourcing ILS1B571S1189 runs through independent distribution against an RFQ — availability, current pricing, and any trace / authenticity documentation are confirmed at quote time, with quantities tied to the lots on hand rather than to a rolling production output.
