Product class C means it is manufactured or produced to order, not a shelf-stocked standard. That translates to a quoted lead time rather than instant availability. For a critical spare like an IPD card, keep this on your min/max watch list — if a G130 drive is in your installed base, you want one of these in the storeroom or a confirmed order in the pipeline before the card faults.
Compliance and regulatory notes
Export Control Regulations are AL: N / ECCN: EAR99H, meaning no special licensing hurdles for most destinations. REACH Article 33 duty to inform applies: Lead (CAS-No. 7439-92-1) is present above the 0.1% (w/w) threshold. This matters for end-of-life recycling reporting and for any customer requiring full substance declarations.
