Lifecycle posture — hot EOL on the order code
The 1FK7042-5AK71-1AG2: The order code is flagged EOL/hot — factory allocation has wound down and the part is no longer shipping on the standard Siemens replenishment cycle. With no official second-source successor on the record from the manufacturer, the realistic supply line for running spares is independent distribution: surplus stock and broker-channel pulls confirmed per RFQ, not a factory delivery date. For an integrator with a live machine, this means the BOM line is a risk-managed spare — purchase against confirmed available quantity rather than a re-order promise, and lock the lead time on the quote rather than at the purchase order.
