How come there's often a wide range in prices for the same part at the same online shop? I can understand it when the same basic device is made by different manufacturers, in different packages, temperature range, tolerance, etc. But there still are often huge differences for a product by the same company with no sub-variant. To give just one example, the Indian branch of Farnell (now element14) currently has three listings of the Vishay TSAL6100 IR LED at Rs.2.90, 17 and 22 each. That's about USD 0.064, 0.38 and 0.49 respectively, a ratio of nearly 1 to 8. What am I missing here?
Big price differences at the same source

The Rs2.90 part is p/n 1469618 and that part appears to be obsolete in the UK. Maybe it is non RoHS. So I guess 2.90 is a stock clearance price.
Within the same supplier, it's usually MOQ/packaging (units of 1 reel) or perhaps there is some subtle difference in the parts.. (not RoHS or something else like performance).
That part is around 0.55 for 1 from Digikey or 12 cents in 10K, but Avnet's 10K price is less than 0.07.
To put it another way, for $1218 you can get 10K pieces from DK or
20K from Avnet (and $18 change). Both say they have stock.Best regards, Spehro Pefhany

Farnell/Element14/Newark often does that. It's a good opportunity to stock up if you want. Or maybe it's a combination of a distributor's catalogue and an intelligence test. ;)
