Big price differences at the same source

    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?
     
  2. 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.
     
  3. 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.
