Product details

What the code points to

The 1FK7042-5AF71-1TA5 is the Siemens 1FK7 compact synchronous servo motor in the brushless AC servomotor class used on SINAMICS and SIMOTION drive lines — the short stack length and the -1TA5 shaft / connector suffix position it inside the 1FK7 family as a low-inertia compact variant.

Lifecycle status and what it means for the BOM

For a contract build that started on this code, the practical sourcing path is independent stock and broker channels: each BOM line is confirmed against current lot availability at quote time, and any deviation from the customer's AVL requires a written change request before substitution can ship.

Frequently asked questions

Where can I buy 1FK7042-5AF71-1TA5 and how do I get a price?

Sourced to order through independent distribution: each request is quoted against current lot availability at the time of the RFQ, with no standing inventory claim and no factory-direct channel.

Will 1FK7042-5AF71-1TA5 drop into a panel that was specified around 1FK7042-5AF71-1DB0 without rewiring?

No — the -1DB0 peer weighs 5.54 kg versus the -1TA5 at 4.54 kg, a 1 kg delta in the same frame that signals a different winding or feedback option rather than a true second-source, so the drive parameter set and the connector / encoder wiring should be re-verified before any swap.
