You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
No. The STMicroelectronics L6599D is marked not-recommended-for-new-designs (NRND): it is still supplied for existing production but the manufacturer discourages new sockets. The qualified alternatives here are better long-term choices for a new design.
The closest qualified second sources for the STMicroelectronics L6599D are the L6599ATDTR (STMicroelectronics) and the L6599ADTR (STMicroelectronics), out of 6 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the L6599D are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The L6599D (STMicroelectronics) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
