While hunting for a cheap R-R opamp that's readily available here in
India, I came across the MCP6001 and 6002. Unusually for the Indian
market, a few sites offer several variants of both single and dual types.

The first three suffix letters stand for temperature range, package and
packing but some have the four extra letters XBLW. These variants for
both single and dual types cost less than a third of the others (roughly
US$0.20 vs $0.75) but I cannot find what the letters stand for. I looked
at datasheets from various sources including the latest one from
Microchip but couldn't find any reference to this extra suffix.

I assume that the extra letters are not batch or date codes. Chinese
copies maybe??

 
Some numbers specify shipping Q = 1000 to 4000.

It's the letters XBLW I'm concerned about, like MCP6002T-I/SN-XBLW, and
why they cost only a fraction of those without the last four letters in
single quantities

Have you tried purchasing the part? Could be marketing restrictions.
