The 348993011: The listed packaging is Box, which typically means a bulk tray or loose-pieces format — hand-load on the line or pick-and-place with a tube feeder if the tray nests.
The alternate MPN 34899-3011 is the same product under a different order-code format; it carries the same Box packaging and active lifecycle, so it's a direct cross-reference if your BOM uses that variant.
