• Feeds a compatible S120 DC-link group at the documented 16 kW power class.
• Provides a rated 27 A DC output in the booksize mechanical system.
• Uses internal air cooling and includes a DRIVE-CLiQ cable.
• Retains IP20 / UL open-type construction for installation inside appropriate equipment.
• Carries a Siemens successor reference that requires documented application review rather than automatic substitution.

• Maintenance of installed SINAMICS S120 systems built around the 6AA4 hardware.
• Spare-part planning for a 16 kW, 27 A Smart Line Module position.
• Brownfield machinery where the original DRIVE-CLiQ topology must be retained.
• Migration studies involving Siemens successor 6SL5130-6UE21-6AC0.
• Controlled replacement work requiring preservation of line-side and DC-link records.

• Siemens marks the article discontinued since 1 October 2024 and in PM490 support.
• The product is no longer available as a current standard article.
• Siemens names 6SL5130-6UE21-6AC0 and directs users to application notes for successor use.
• A migration review must cover dimensions, connections, line components, firmware and system behavior.
• Back up the drive project and complete functional validation after any replacement or migration.

Is 6SL3130-6TE21-6AA4 still a current product?

No. Siemens lists it as discontinued since 1 October 2024 and in the PM490 support phase.

Which successor does Siemens name?

The official product notice points to 6SL5130-6UE21-6AC0 and requires review of the related successor-use notes.

Does the successor constitute a drop-in replacement?

The Siemens notice calls for application guidance, so compatibility must be checked rather than assumed.

What are the original electrical ratings?

The legacy module is rated 16 kW with a 600 V DC, 27 A output from a 380–480 V three-phase input.

What cabinet size did the original module use?

The official data gives 100 × 380 × 270 mm for width, height and depth.

Which records are important for migration?

Retain the full drive project, line-side components, DC-link topology, cabinet layout and connected Motor Module data.
