Compatible Replacement & Equivalent Models
The following models are commonly evaluated as functional replacements or equivalents for the 6GK1105-2AE00. Always verify electrical, mechanical, and firmware compatibility before substitution.
- SIEMENS 6GK1105-2AB00 – OSM TP22 EEC (extended temperature variant, −40 °C to +70 °C); direct functional equivalent for harsh environments
- SIEMENS 6GK1105-2AD00 – OSM TP22 with different fiber port configuration; verify port mapping before replacement
- SIEMENS 6GK1105-3AB00 – OSM ITP62 (6 TP + 2 fiber); suitable when more TP ports are required
- SIEMENS 6GK1108-0AA00 – ESM TP80 (8-port TP switch); suitable for pure copper topologies without fiber requirement
- SIEMENS 6GK5208-0BA10-2AA3 – SCALANCE X208 (managed, 8-port); recommended upgrade path for new installations requiring SNMP/web management
- SIEMENS 6GK5216-0BA00-2AA3 – SCALANCE X216; suitable for larger port-count requirements
Note: OSM/ESM series modules are legacy products. SCALANCE X-series is the recommended successor platform for new designs.

- OSM/ESM Ring Topology – Supports up to 50 nodes per optical ring segment
Selection Guide
Use the following criteria to determine whether the 6GK1105-2AE00 is the right choice or to identify a suitable alternative:
- Fiber required? → Yes: OSM series (6GK1105-2AE00 or equivalent). No: ESM TP series or SCALANCE X208
- Extended temperature needed (below 0 °C)? → Select 6GK1105-2AB00 (EEC variant) or SCALANCE XC-200 series
- Management & SNMP required? → Upgrade to SCALANCE X208 (6GK5208-0BA10-2AA3) or higher
- More than 2 TP ports needed? → Consider OSM ITP62 (6GK1105-3AB00) or SCALANCE X216
- Replacing a failed unit in existing ring? → Use 6GK1105-2AE00 for direct drop-in replacement; no network reconfiguration needed
- New installation / greenfield? → Evaluate SCALANCE X-200 or X-300 series for future-proof managed switching
- Budget-constrained spare? → Verified OEM-grade 6GK1105-2AE00 from authorized distributors is the safest option

Replacement & Compatibility FAQ
Q: Can I replace a 6GK1105-2AE00 with a SCALANCE X208 without reconfiguring the ring?
A: No. SCALANCE X-series uses a different ring redundancy protocol (MRP vs. OSM proprietary ring). A full network reconfiguration is required. Recommended only for planned upgrades, not emergency replacements.
Q: Is the 6GK1105-2AE00 still in production?
A: This model is a legacy/discontinued product. SIEMENS recommends SCALANCE X-series as the successor. However, OEM-grade spare units remain available through authorized distributors including Konmask.com.
Q: What fiber cable is required?
A: Multimode fiber, 62.5/125 µm, with BFOC/2.5 (ST-type) connectors. Maximum segment length is 3 km at 10 Mbps and 2 km at 100 Mbps.
Q: Can this module be used with PROFINET?
A: The OSM TP22 operates at the Ethernet layer and is transparent to PROFINET traffic. It does not natively support PROFINET diagnostics or topology detection. For full PROFINET integration, use SCALANCE X-series with PROFINET support.
Q: What is the lead time for this part?
A: Typical lead time is 3–10 business days depending on stock availability. Contact us for real-time inventory status.
Q: Do you provide a certificate of conformity?
A: Yes. A certificate of conformity and inspection report can be provided upon request at no additional charge.
