Listed lifecycle status is EOL — meaning the factory has retired the order code and the only fresh supply runs through independent distribution, with lot-specific availability confirmed against an RFQ. ## Why the 4.08 kg figure matters before you commit Mounting and shaft details are not in the listing — the encoder resolver/absolute interface, brake option and connector orientation must be confirmed against the nameplate on the motor in the cabinet before a replacement is commissioned, because two 1FK7 variants with the same frame length can carry different feedback modules and are not drop-in for one another. ## Sourcing posture for an EOL Siemens servo With the part marked EOL, expect no factory-direct replenishment — every quoted unit comes from independent surplus or refurb stock, and each lot carries its own trace history, age and storage record, so the procurement-side decision is whether the encoder alignment, insulation resistance and bearing health on the offered unit still match a service window you can sign off on.","metaTitle":"Siemens 1FK7042-5AF71-1AA0 Servo Motor, 4.08 kg, EOL","metaDescription":"Siemens 1FK7042-5AF71-1AA0 — 1FK7 compact synchronous servo motor, 4.08 kg, listed EOL.
