Product Identifiers at Infineon
Currently there are two relevant product levels: Salesname and SP number. The salesname describes the functional attributes of a product (e.g. supply voltage, frequency, memory) and it is also contained in the pCPN that some customers use to order today.
The SP number is the non-descriptive order relevant sub-level number to the salesname. The SP number is a concise relation to the actual part itself specifying the packing type or size, RoHS/Halogen distinctions, customer specific variants and other product variants such as temperature ranges. Because multiple SP numbers can be assigned to one salesname, the OPN is a unique and descriptive identifier with a 1:1 relation to the SP number.
How does the OPN fit into the existing part numbering scheme?
Because the SP number is the order relevant level, the OPN is a descriptive and unique identifier with a 1:1 relation to the SP number. The Salesname does not carry sufficient information for ordering because multiple SP numbers can be assigned to one salesname.
This is possible by combining the salesname and the following additional attributes:
- RoHS status
- Halogen status
- Totally lead free status
- Packing type
- Packing size
- Moisture protection packing
Because these are the main, but not the only reasons for many SP numbers under one salesname it is also possible to depict any other reason (e.g. test versions, micro codes) in the designator.
The OPN will replace the proposed Customer Part Number (pCPN) which could be used as a customer part number.
