What this line item actually is
The 6SL5166-2NB00-0AA0 from Siemens is the SINAMICS S220 power connector with push-in termination, specified for the SLM 16/24 kW booksize design — it is the line-side connector accessory that mates to the Smart Line Module, not a standalone drive. Lifecycle is active on the manufacturer record, so a procurement order placed today is being pulled from current production rather than the surplus channel; production status is referenced under current on the ordering data. It carries product class C — built to order, non-returnable, non-reusable — which is the normal posture for a configured accessory but means any quantity committed on the BOM cannot be returned for credit if the panel design changes.
Compliance and declaration pack
RoHS compliance is declared since 27-05-22, and the part falls under export control classification AL: N / ECCN: EAR99H — the declaration pack a quality or compliance buyer will request should carry these two lines without further escalation. REACH Art. 33 duty-to-inform applies in the standard Siemens form (Reach Information on file), which is the expected entry on a European-jurisdiction declaration of conformity for this accessory class.
Ordering posture for the BOM
Quantity unit is 1 piece with packaging quantity 1, consistent with a single connector per S220 booksize SLM rather than a bulk line — order quantities track the SLM count on the bill of materials, not a volume discount ladder. Group code R220 and product group X0HX are the internal ordering identifiers the procurement system uses to route the line inside the Siemens catalog — they confirm the part sits in the SINAMICS S220 accessories block and not the V90/V20 spare-parts bucket.
Category fit and panel-side use
Servo drive accessories of this class are typically specified once with the SLM and re-ordered only as field-replacement spares; a panel builder normally buys one or two extras per build to cover cabinet rework without holding inventory against an active BOM line.
