How to identify part numbers
Many items have multiple part numbers. The part you receive might seem to be a different part because of the part number, but it is usually the same part. We carefully review all part numbers so we can ship the correct parts to you.
If a replacement part is sent to you, we clearly state on your order that we sent a replacement part. If for any reason a replacement part is unsatisfactory to you, we will give you a 100% refund, but you must notify us within 10 days of receiving the order.
Examples:
1) IBM parts usually have 2, 3 or 4 part numbers printed on the unit. They have a number with a prefix of FRU (Field Replacement Unit), ASM number, APN number (Art Part Number), CRU (Consumer replacement unit), and they sometimes have a MPN number (Marketing Part Number)
2) Usually manufacturers use part numbers to identify certain characteristics such as country of origin, country of destination, revision, marketing purpose, OEM manufacturer, etc. For example Compaq has 14 part numbers for unit 222114-001 Li-Ion Battery Pack (222114-001, 116314-001, 388644-B21, 138184-001, etc)
3) All laptop manufacturers use OEM parts (i.e., parts that have been manufactured by a company that specializes in that item). Therefore, these parts will usually have 2 or 3 part numbers. For example, the Toshiba COLOR LCD DISPLAY part number K000833610 has been manufactured by Sharp with the part number LQ141X1LH82. Depending on supply and demand we will ship the product that it is available.
In the picture you can see a perfect example of a single part with multiple Part Numbers, in this case this hard drive has three "Branded" Part Numbers and the OEM Part Number. This hard drive can be shipped for any order where any of these part numbers is requested.
