The Siemens 6SL3351-3AF34-7DB0 is a SINAMICS G150 Replacement IPD card — a spare part for the G150 drive family, not a standalone module. It carries Group Code R2SC and Product Group 4Q30, both internal Siemens classification tags that help cross-reference the correct variant in ordering tools. Product class C means it is manufactured or produced to order and cannot be reused, re-utilized, or returned against credit. This is a one-way spare — order exactly what the BOM calls, because it will not go back on the shelf.
Export Control Regulations list AL: N / ECCN: EAR99H — no special license required for most destinations. This is a standard declaration for industrial electronics; it does not restrict sale or installation in most regions.
