Temp sensor BME280 c18 vs j34

This is probably a silly question, on Aliexpress I see 2 differents BME280 sensor that look very similar, however in their title one says c18 and the other on j34. What is the difference? Thank you.

@Freedom1029 it is hard to tell, this is not an official number code of the bme280 sensor itself. Probably just an internal partnumber.

Really an old topic but for those still curious; those codes usually are used for sellers working with agents. I mean, "XXX" seller has 5 agents but only one account (kind-a franchise type) so to track who sold what they use those codes. At least this is what one of ebay sellers told me when out of curiosity I asked one day.
