NOTES:

• RoHS compliant products. (G = RoHS Compliant)

• Vendor specific part numbers are used to provide memory components source control. The place holder for this is shown as lower case “x” in the part numbers above and is to be

replaced with the respective vendors code. Consult factory for qualified sourcing options. (M = Micron, S = Samsung & consult factory for others)

• Consult factory for availability of industrial temperature (-40°C to 85°C) option

• In an effort to support our customer’s traceability and control requirements (which enables them to quickly identify component speed grades used on modules in the field); WEDC

has created a “26A” module part number option. The W3EG2128M72AFSR26AAD3xG product part number meets all the requirements of the W3EG2128M72AFSR265AD3xG

product however it is built using 400Mhz rated components. We recommend therefore that customers include both the “26A” and “265” final part numbers on their AVL in order to

support flexibility of sourcing and to allow for the best module sourcing lead times. For those customers who wish to allow both sourcing options but only would like to include one

product part number on their AVL, WEDC can accommodate. Please consult factory for more details.
