Distributors are so thick nowadays

If I am placing an order for say 200k resistors, 50k (10 reels) each of 4 values, the disti should be able to find the P/Ns.

Normally, nowadays, in fact right now, it is Yageo, but in a few months' time it might be another name. If you get the wrong P/N, or last year's favourite P/N, you could pay 10x more.

These distis will not help you even if you wanted to buy 1 million resistors.

It was not uncommon for customers to have the AVL or "Approved Vendor List" of second and third source parts that was given to the assembly house and carefully crafted with the help of a distributor. However, to get a real customer service, the volumes were horrendously high and the BOM was closed with a single distributor. The high volume off quotes could be followed by a call from the FAE to inquire about the design you were running that requires such high part count - the customers that didn't want to share this information got a corresponding service and pricing; the ones that opened the door got much better service.

BTW, I don't disagree with your assertive that the distributor should be able to find the P/Ns but, with the shrinking market on the distribution business, their personnel are probably stretched thin.

That's not relevant without another parameter - $
In your case, less than <$1K in total for whole order.

10 reels each of 4 values is 40 reels , at 5 to 6% areel .. that's 240$ .. and you wonder why they don;t respond. picking up the phone and listening to you just ate their profit margin .

You are all missing the point that this is an RFQ not an order. The liability element comes when you get the quotation back and check what parts have been offered against your specification; if you accept the RFQ as the basis for an order you are signing off that part XYZ-RQ-12-89-X is an acceptable supply for "10k resistor 0805 1%" then you, as customer, accept liability for that choice.

Not quite. On a few occasions I have sent a preliminary BOM to Supplychain/Procurement/Purchasing for RFQ to get pricing on the build.
Because parts can have long lead-times, I find out later that the Manufacturing manager ordered all the parts on the BOM :palm: even though the product has not finished approvals and is months away from production. I'd signed-off on nothing.
He's trying to cover his (procurement) ass and be ready to manufacture ASAP. Engineering does not control Purchasing.

Another company I worked for, when the product was ready for production, Supplychain had ordered nothing  :=\ and there were parts with many months lead-times on the BOM and they were caught with their pants down. Even worse, some parts such as RF modem modules, manufacturers demand your draw-down quantities and dates well in advance, along with a signed commitment to order that.

I wish it was straightforward to get an RFQ but I find the politics around it are incredible because it involves a few departments and none of them are very competent.
