1FK7042 in the 1FK7 series, flagged end-of-life
The 1FK70422AF711PG1-Z+J29: Lifecycle reads EOL hot — the part is in its last production window and new-build inventory is moving through surplus and broker channels rather than the standard factory spool. Spec carry-through (shaft, encoder, brake options) is the priority now, since the factory is not replenishing the live order book the way it would for an active series.
Sourcing posture for a last-build servo
With EOL hot, the practical move is to quote to order against an RFQ: confirm availability, lot size, and factory-traceable condition before committing a BOM line. Pricing and lead time are established at quote time from the independent channel carrying remaining stock and decommissioned builds. Pin-compatibility for this MPN is a 1FK7-frame question only — no second source from another manufacturer exists, and any successor stays inside Siemens' own 1FK7 successor designations. Buyers chasing a drop-in replacement should match frame size, shaft, encoder, and brake options rather than chasing a close-rated substitute from a different series.
