Win-source?

[jrs45]

Are they reputable?  They have some parts I need that are out of stock elsewhere, but there are so many scammy suppliers on octopart I'd want to be very cautious.

[mon2]

Yes, they are very reliable. Have used them a number of times including to source from them and drop ship to a medical approved CM in Shenzhen for a PCB assembly for a surgical robot controller. The CM builds for AMD and other key OEMs. Purchased some components that are factory new but surplus, factory sealed with current date codes at a fraction of the prices we have paid in North America. The key reason here was to do a rush build for a client who was pressed for a reduced lead time - often our customers give us zero forecasts but expect miracles on delivery cycles. Win-Source had stock of the referenced goods.

No issues with dealing with Win-Source to date. They are ISO certified. You can, at your option, negotiate the best pricing but found them to be always fair.

I also ended up using them for to fill in part shortages. The prices were marked up quite a bit, but no issue with shipping or payment. 1 week shipping to Canada. Parts were as advertised no issues or defects, shipped in reel.

[Selectech]

Ordered 3 reels of Toshiba fets, they had lots in stock, and pricing was best of any that had stock.  Delivery to Canada was about a week ( via DHL ), all good.

On any of their product listing, there's this entry of: Fake Threat In the Open Market = xx percent.
Are they suggesting theirs could be counterfeit?

They are probably suggesting the ones you find on the "Open Market" could be counterfeit?

[48X24X48X]

Going to give them a try as some parts are just zero stocks everywhere else.

[Howardlong]

Mediocre.

Beware that they play a game where they present competitive pricing, then come back to you with a rubber stamped reply saying that "parts were been found not in good condition by our engineer before the shipment", and then offer you the same part at grossly inflated pricing, and more than the stock they are still advertising.

Example 1, MGA-62563 RF amplifier was inflated from their advertised $1.73 to $3.60 (I eventually pointed out they were still advertising at $3.059, which I got despite my crap haggling skills).

Example 2, TLV320AIC3204 codec was inflated from $1.10 to $2.22, but I told them to stuff it. With all the delays in responses (I'd had to chase them up) I'd already gone somewhere else.

The problem with this isn't just that there would appear to be some systemic misrepresentation of pricing based on my experiences, it's that typically this haggling nonsense adds significant delays.

For Example 1, the devices finally arrived in cut tape inside original Avago sealed packaging. I performed a sample test and they were fine.

The current semiconductor shortages are inevitably pushing BOM prices up. I'm currently able to shoulder those costs, but for those with business models supporting narrower margins that won't be possible, and price increases to retail customers are inevitable.

[jrs45]

They pulled that with me, too. But the final price was still comparable with that from other distributors.

[YurkshireLad]

Wow, just wow. They even send exactly the same email and don't even bother to make it personal or hide what they're doing.

[Howardlong]

Mother ******s just did it again.

I told them they had the choice to either ship at their advertised price (that they're still advertising) or **** right off.

[NorthGuy]

Prices seem bogus at best:

https://www.win-source.net/xilinx-inc.-xc7a35t-1ftg256i.html

This is the same part, except for temperature range. Both "in stock" with 300 pieces (looks like bogus number too - the tray is 90 pieces). Price for C is $179, Price for I is $27.

How can you possibly trust them enough to place an order?

After the stunt they pulled on me earlier this week (rack up the price upon making an inquiry) I won't attempt to deal with them again. Not to mention asking far too much for parts without trustworthy provenance.

TBF, they do deliver kosher parts... but the 100% bait-and-switch is pure bullshit.

[jrs45]

This was my experience as well.  They used the "improperly stored" excuse.  But the final price was comparable to other mainstream distributors, fwiw.

[Centmo]

Dishonest supplier. After ordering parts and paying for them in full, I was notified a week later that the parts had gone up in price 4x, and I would need to pay the higher price. I declined and was refunded. On another order, one month after payment I emailed to ask when the parts would ship and was told that in fact they didn't have the stock so they would have to refund me (minus exchange fee). Finding this suspicious, I requested a quote for the same part from a different email address and was given a price 3x what I paid and was told they have plenty in stock and ready to ship in 2-3 days.

In addition to the ordering issues, a colleague of mine discovered that they has used a fake humidity card in an old order. The bag had been sitting open for months and none of the humidity levels had triggered.

Very dishonest business, steer clear.

[Howardlong]

Same old sh!t

Dear Howard,
 
Sincerely thanks for your order online.

We are sorry to inform you that the price of the  parts you ordered has to be adjusted due to market fluctuations.

To avoid your supply chain disruptions, the refund request of payment has been submitted. It might take 3-5 business days for the payment to refund but I will get back to you ASAP.
 
Please also kindly confirm the following updated details for your reference if you are interested.
 
Part Number                             Order Pirce   Updated Price   Quantity   Total difference of the Amount
TLV320AIC3204IRHBR                  $2.509             $3.28            400pcs          $308.4

As the risk warning displayed on the order page, under the special circumstances of recent electronic components, we are also troubled by the shortage of components and the chaos of the market.
 
We are very unwilling to increase the price if there is no threat on the markets. Regarding to the price changes, we always try our best to negotiate with our supplier, strive for the lowest price to minimize the procurement costs and ensure the safety and stability of customer supply chains.
 
We would always suggest our customers hold the order first and pay close attention to price changes in the near future, if the components are not urgent for production or circulation.
 
Please allow us to send you an order invoice of the difference amount if you could accept the updates.
Or
Please be patient for the full refund if the price exceeds your purchase budget.
 
Further discussion please feel free to contact me. Thank you.

Best Regards,

Win-source needs a flying roundhouse kick for their gouging methods.

Have to ask - why would you NOT buy directly from the TI webstore ? They have the parts currently in stock..grab them before Win-source does...

I already did: at the time I placed the order with Win-Source, there was zero availability.

[Feynman]

We occasionally order parts from them.

The price is high of course, but that is the market. I'm a capitalist at heart and high prices are the only real solution in the long term when supply is low and demand is high. And after an order the price might change a little (low one digit percentage). The parts appear to be genuine and are properly packaged (ESD, moisture). Due to CoViD restrictions it might take a while for the shipment to leave and the support is not too responsive (but will respond eventually most of the time). Apart from that, we can't complain.

You can give them a chance in emergency situations, I guess. But don't expect the parts to arrive in a couple of days or the price being constant to the cent.
Don't rely on anything, basically. And get the ok from your customer to buy parts from unauthorized vendors like Win-Source.

There are vendors out there that are 100% scam. I don't think Win-Source falls into this category.

[jrs45]

Thanks.  Since the original post I've done several orders with Win-Source, holding my nose at the prices sometimes (but I haven't bought anything too egregious).  The most important issue is whether they are selling good parts that are what they claim they are.  So far, all the parts have been exactly what we ordered, and in good condition as far as we can tell.

[Howardlong]

But don't expect the parts to arrive in a couple of days or the price being constant to the cent.

"to the cent"

But it's not just a cent or two, is it?

I am a capitalist too. That doesn't mean it's acceptable EVERY TIME to advertise at one price, take your money, and then turn around a few days later and say, oh, we didn't mean $2 we meant $3... or $10. In most western jurisdictions that is an illegal practice, and for good reason. It has nothing to do with capitalism.

Guys, just don't use Win-source!

We recently had no choice but to go grey-market for a thermocouple amplifier IC after AD pushed their lead times back further. I dealt with Worldway electronics who, despite still having a painful price, were open to some negotiation and did not play any games like Win-source who regularly do.

MAX6675/MAX31855/MAX31856? These are notoriously known for fake parts.

AD8495. I'm aware of the risk but the customer demanded no interruption to supply of the finished product and was willing to pay the price and risk. We qualified the parts as much as possible prior to use.
