Because the part is flagged EOL/HOT, the practical build decision is no longer 'order the current catalogue' — it is 'confirm the last-time-buy window, then quote quantity and lead time before the BOM is frozen'. ## Lifecycle read: the rating that drives the BOM decision For the line-down case, the realistic posture is: pull a quote with the quantity, confirm whether the order lands on factory stock or independent-channel stock, and freeze the lead time before specs that depend on this exact shaft-and-encoder suffix drift. ## Where it sits in the panel and on the machine Mounting is a standard 1FK7 flange — the motor bolts to the gearbox or machine face, the power and feedback cables exit axially or radially depending on the connector option, and the resolver/encoder plugs into the SINAMICS drive's feedback port with the matching Siemens pre-fabricated cable. ## Sibling parts: same frame, different options Use of those peers as a second-source depends on matching the feedback type, holding-brake option, shaft geometry and connector orientation from the option-code suffix, not just the frame — confirm the suffix breakdown against the BOM position before substituting.","metaTitle":"Siemens 1FK7042-5AK71-1UH5 Servo Motor, 5.44 kg","metaDescription":"Siemens 1FK7 compact synchronous servo, 1FK7042-5AK71-1UH5, 5.44 kg.
