Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or alternatives to the 6SL3120-2TE15-0AA4. Always verify electrical and mechanical compatibility before substitution:
- 6SL3120-2TE13-0AA3 – Previous generation double motor module, lower output current (3 A/axis); suitable for lighter loads
- 6SL3120-2TE21-0AA3 – Higher current variant (10 A/axis); drop-in upgrade for higher torque requirements
- 6SL3120-2TE21-8AA3 – Enhanced version with Safety Integrated functions
- 6SL3120-1TE23-0AA3 – Single motor module equivalent for single-axis applications
- 6SL3120-2TE15-0AD0 – Variant with different firmware/hardware revision; confirm compatibility with your CU320-2 or CU310-2 control unit
Note: Cross-referencing requires matching DC bus voltage, output current, DRIVE-CLiQ firmware version, and booksize form factor. Contact Konmask for verified compatibility checks.

Selection Guide
Use the table below to select the correct SINAMICS S120 Double Motor Module for your application:
| Parameter | Consideration |
|---|---|
| Output current per axis | Match to motor rated current × 1.1 safety factor |
| Number of axes | Double module (2 axes) vs. Single module (1 axis) |
| Safety requirements | Standard vs. Safety Integrated (SIL2/PLe) |
| DC bus voltage | Must match line module output (typically 600 V DC) |
| Cooling method | Internal fan (standard) vs. Cold plate (chassis) |
| Firmware version | Must be compatible with your CU firmware version |

Replacement & Compatibility FAQ
Q: Can I replace 6SL3120-2TE15-0AA4 with 6SL3120-2TE21-0AA3?
A: Yes, if your motor requires more than 5 A per axis. The 10 A variant is a direct form-factor replacement but verify firmware compatibility with your control unit.
Q: Is this module compatible with SINAMICS S120 Chassis format?
A: No. The 6SL3120-2TE15-0AA4 is Booksize format only. For Chassis format, refer to the 6SL3121 series.
Q: Can I use a third-party motor with this module?
A: Yes, with proper encoder interface configuration. DRIVE-CLiQ motors are plug-and-play; non-DRIVE-CLiQ motors require a Sensor Module (SMC/SME).
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For new factory orders, lead time is typically 8–14 weeks. Contact us for current availability.
Q: Do you provide a test report?
A: Yes. All refurbished and tested-used units include a functional test report upon request.
