Till date have worked on more than 100K unique parts and have fair experience, i own few scrubbing tools, Can generate the bom from only given descriptions for new design. I can give you a scrub results for free with this and can provide ROHS/REACH/ROHS-2/MSL/Soldering profiles/Pricing/Mounting/Leads/Packaging and Cross parts (FFF Alternates) for any non rohs and eol parts respectively.
Scrubbing report from my tool shows the parts life cycle stages and any threats involving in obsolescence and supply chain risks. i am interested in this, I can give you more services related to component engineering and RFQ sourcing at very affordable price.
Thank you,
Venky
