Replacement & Compatibility FAQ
Q: Can the 6GK5646-2GS00-2AC2 replace an older SCALANCE X-200 switch?
A: In most cases yes — the XC-200 series is backward-compatible with X-200 at the port and PROFINET level, but verify MRP ring configuration and firmware version in TIA Portal before swapping.
Q: Is a third-party SFP module compatible?
A: Siemens recommends its own SFP modules; however, standard 1000BASE-SX/LX SFPs from reputable vendors typically work. Konmask can supply matched SFP pairs on request.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 2–6 weeks depending on Siemens production schedule.
Q: Do you provide a warranty?
A: Yes — 12-month warranty against manufacturing defects. DOA (Dead on Arrival) units are replaced at no charge.
Q: Can I get a datasheet or GSDML file?
A: Yes, contact us and we will provide the official Siemens datasheet and GSDML file for TIA Portal integration.
