What this voltage reference is and where it lands
The MX584KH is a voltage reference device from the * series. It's the kind of part you find holding a stable DC rail for an ADC, a comparator threshold, or a regulator feedback divider — the sort of component a board-level repair tech might swap on site if the output drifts.
RoHS status — a real BOM constraint
This part is RoHS non-compliant. That matters if your BOM requires lead-free assembly or if you're shipping into jurisdictions that enforce RoHS exemptions strictly. For MRO spares or legacy board repairs where the original solder spec was tin-lead, this is actually the right call — you don't want a lead-free part reflowed with SnPb paste. If your design mandates RoHS compliance, you'll need to look at a different voltage reference entirely; there's no RoHS-compliant variant of this exact code.
Sourcing and lifecycle — active, but with a catch
No last-time-buy clock ticking, no EOL notice to chase. The catch is the RoHS non-compliance: some distributors may stock it only in legacy inventory, and lead times could be longer than a fully RoHS-compliant equivalent. We source it to order against an RFQ through independent distribution — availability and current pricing get confirmed at quote time, not on a public listing.
