What the part is and why it matters now
The 1FK7042-5AF71-1SA2: Lifecycle is flagged EOL/hot, which means the part has entered the wind-down phase of production but is still orderable on a last-time-buy posture — the BOM line stays buildable for the near term, then the channel shifts to surplus and independent stock.
Sourcing posture for a hot/EOL servo
With the part sitting in EOL/hot, the procurement question is no longer fit — it is volume security: how many pieces the last-time-buy window will release, and whether independent stock carries traceable surplus once the factory channel narrows.
