What happened?All previously valid URLs seem to 404, like this one:https://www.digikey.com.au/en/products/detail/mornsun-america-llc/B1212S-1WR3/13968708Now the manufacturer is not even listed on the distributor's sites. Does not seem country specific, and the Mornsun product pages still look intact:https://www.mornsun-power.com/index/sitesearch/partlink/keyword/B1212S-1WR3.htmlEerie...

content: Strange. What I have used of their little ones have been really good value and worked well.I have recently been buying some larger 10-20W DC-DC and AC-DC convertors from this seller and they have an actual website. Mainly used as Pi power supplies but I have hammered them on a DC load to test them as well.There smaller 2W ones are I suspect Mornsun clones or badged but worth looking at too.https://www.aliexpress.com/store/345286/pages/all-items.html?productGroupId=40000000582067&spm=a2g0o.detail.0.0.2398rfcvrfcvwK&storeId=345286&sortType=bestmatch_sort&shop_sortType=bestmatch_sort

content: May 1, 2024 round ofUS sanctionshas Mornsun on the list for "... support{ing} Russia's military-industrial base".It's a supply chain disruption. What pisses me off is companies are now scooping up stock of the other companies making the same products like CUI, RECOM etc. and there is no stock and their parts are now on allocation.I have to wonder what the point is- as these modules are made in China anyway. If it's from Mornsun or RECOM, the dollars flow to China regardless.So the sanction does what exactly?

We have to understand what happens POOF when sanctions take out a component you are using, have designed in and can no longer source, oh and the alternate part's price has doubled. I'm not sure if there was any forewarning.I find the irony is that these components are manufactured in China, entirely. Mornsun they are a Chinese company but several others - COO is China so at best the sanctions causes a back-channel to take up the slack. In other words I don't see the sanctions accomplishing anything other than Mornsun losing some sales.

Not much you can do other than use more generic parts with multiple sourcing options, or buy years of stock ahead of time and avoid the US market.In this case, Canada does not have the same sanctions as USA, so Canadians can buy from LCSC. But, make sure you don't sell the product to USA:https://www.tradecommissioner.gc.ca/guides/us-export_eu/141452.aspx?lang=eng#us43https://www.lcsc.com/product-detail/Power-Modules_MORNSUN-Guangzhou-S-T-B0505S-1WR3_C131038.html

content: Quote from: mikeselectricstuff on May 07, 2024, 09:54:10 amMight be that the stock is on consignment - Mornsun would get paid only once it is sold. This is common for lower volume items in retail, and it removes the risk Digi-Key has of stocking a SKU that doesn't shift too much. But it will mean that the stock hasn't been purchased yet, it's only in Digi-Key's inventory, and therefore can't be sold on as Mornsun would be due to be paid.

content: Irrespective of the political situation, single-sourcing is always risky.Power supplies are usually not that much of a problem to replace, even if it's always inconvenient. At least, compared to more specific devices. Imagine having picked a specific chinese MCU for some product, and the vendor suddenly gets banned. Fun stuff.

content: Quote from: SiliconWizard on May 09, 2024, 08:48:32 pmIt makes me wonder though how this would work out for products you have assembled in Asia where they won't be affected by blacklisted companies to source components. You can't do a full supply chain trace on everything as many components themselves are assembled from various other components. This is not limited to power supply modules but consider RGB leds with an integrated controller for example.

At least I haven't seen authorities (yet) asking companies to declare the whole BOM of every product they sell, just in case. Imagine that. Although, I may be surprised by the creativity of bureaucracy. Question: if you import an assembled board, are you considered importing every single part it's made of? Ditto for an end product? (I might need some aspirin after I get answers.)

This would include freezing their assets (potentially including items stocked at distributers) and prohibiting US-based individuals and companies from doing business with them. Importing goods containing their products into the US shouldn't be illegal per se but might be depending on the specific circumstances.

Hopefully another non-US stockist takes over distribution.If you have a product that contains Mornsun components and you export to US, are you in the clear? EO14024 seems to only affect a listed person's ability to do business with any US person.

But if it was already sold to a distributor, it is no longer the property of the embargoed company. So it really depends on whether the distributor purchased and paid for goods (i.e. distributor has full ownership) or whether they have the goods on consignment (manufacturer has ownership).

content: Quote from: 5U4GB on May 12, 2024, 12:53:42 pmUS companies are legally required to at least make an effort to prevent their exports from ending up in hands they aren't supposed to, and they will keep a paper trail to demonstrate compliance with those requirements. Hence the threads you occasionally see here complaining about Digikey or Mouser requiring additional paperwork from, or even denying sales outright to people in other countries. So it's a lot easier for them to at least make the argument that they did their best, and they have plenty of properly-completed forms to prove it. I doubt that Mornsun is in the same position.Quote from: tooki on May 17, 2024, 04:24:35 pmIANAL either, but this is my interpretation as well. The target is the assets of the sanctioned entity, not their products. One of the hints here is that the sanctions are administered by the Office of Foreign Asset Control, not the Department of Commerce (which administers general commercial import/export controls) or Department of State (which administers import/export controls for 'munitions', which really means anything with military implications).One of our overseas suppliers recently started using Mornsun PSUs in an assembly they produce for us. We'll ask them to use a different supplier going forward to be on the safe side, but it's not clear to me if that's even necessary, since they're no longer Mornsun's "property" once they get to us. I've asked a federal contact who's helped us navigate export controls in the past for guidance, will hopefully hear back on Monday.As an aside for anyone in the US who's having trouble navigating export requirements: get in touch with your localUS Commercial Serviceoffice, they have teams of people who are paid to help you deal with those things, and if they don't know the answer they can connect you to the people who do.

content: Unfortunately this ban caused a headache for a project with a client. I am helping them with a design that is essentially a "one off" (or more like 15....) for a piece of specific to a manufacturing process.We used a Mornsun HO1-P1251H-1B (5v to 1500v supply). It was was a simple solution for a specific problem (need a low-power, but controllable 0-1500v for a manufacturing process). The QTY was so low it didn't make sense to design the circuit from scratch, especially when the Mornsun option was only about $35USD and worked well. We got notice of the ban right before ordering the PCBs. Not huge impact long term but one of those annoying things as I was about 15 minutes away from order 30 of the power supplies to keep on the shelf for the lifetime of the project.Luckily I had 5 of the supplies that were purchased for evaluation. We decided to moved for with the design as is and just use the footprint as the "formfactor" for something else we will design/drop in.Or maybe I can find someone that has excess inventory. Right before the ban, Digikey had several thousand in stock. So, I know they are sitting on a shelf not to far away......Just a weird situation. I feel that there must be more going on behind the scenes. (more than just having parts in Russian Military equipment).
