Orderable Part Number (OPN)

The Orderable Part Number (OPN) is a unique and descriptive product identifier. It improves ordering, product identification and communication.

1: OPN Structure

The OPN salesname can differ from the actual salesname:

  1. It does not contain any special characters such as blanks or dashes
  2. If the salesname exceeds 19 digits after the elimination of special characters it will be adjusted to fit the maximum length of the OPN (24 digits)
  3. Microcontroller products with an SA prefix will not have this prefix in the OPN salesname. Additionally the temperature identifier will be moved to the end of the OPN salesname (Microcontroller products only)

The OPN suffix describes the product in more detail:

  • RoHS status
  • Halogen status
  • Totally lead free status
  • Packing type 
  • Packing size 
  • Moisture protection packing

2nd and 3d digit: Packing type, Moisture Protection Packing and Packing Size

The 2nd digit shows the functional packing type in combination with the moisture protection packing.

The 3rd digit shows the number of devices per functional packing or the number of functional packings (denoted with 1)

Examples for packing type- and size

  1. TLE4250G with OPN TLE4250GNTSA1 and TLE4250GNTMA1. This product comes on two different reel sizes: 180mm and 330mm. One can see from the second digit that the product comes on tape & reel (T). Now the packing size can be determined by the third identifier. This product comes as “S” and “M”. “S” means 180mm, “M” means 330mm. Even if this detail was not known, it becomes obvious on first sight that TLE4250GNTSA1 is smaller than TLE4250GNTMA1.
  2. SAE800G with OPN SAE800GXLLA1. This product comes in Tubes (indicated by the “L” in the 2nd digit ). The third digit of the OPN is also an “L” which indicates that there are between 21 and 40 tubes per box.
  3. SIPC03S2N03L with OPN SIPC03S2N03LX3MA1. This product comes on Tape & Reel bare die (3). The third identifiers (M) indicates that there are between 2001 and 5000 bare dies on the reel.

Although none of the packing size indications gives an exact number of products per packing, it allows you to distinguish between two different products: You can immediately see which product

4th and 5th digit: Designator

The designator increments (e.g. from A1 to A2) whenever a new SP number is set up that does not differ from a previous product in either Salesname or the first three OPN suffix identifiers. Product variants such as different temperature ranges or ROM codes can therefore be recognized by the designator.

Existing identifiers

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: 

  1. RoHS status
  2. Halogen status
  3. Totally lead free status
  4. Packing type 
  5. Packing size 
  6. 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.

4: Frequently asked questions

The OPN is a descriptive ordering code that consists of an adapted Infineon sales type (“ salesname”) and five additional digits describing the product in more detail. Descriptive means that the OPN can be "translated" into exact product attributes.

The order relevant ordering code is the SP number which is not descriptive though because it is simply a number that has no particular meaning. This means that you can´t see which product is behind the SP number (e.g. a discrete or microcontroller). It is also not possible to see differences between SP numbers. Our descriptive ordering code is the salesname. By knowing its nomenclature you can easily determine the product group and the product attributes. However, one Salesname (e.g. the microcontroller SAB C165-LM) can have several SP numbers. There are many reasons why this can happen: Different packing types, green and grey versions, customer specific versions etc. So using the SP number is not convenient because the product behind it is not visible, using the salesname is not sufficient because it can have many ordering codes. The OPN solves both problems by creating an ordering code on the SP level that shows all relevant attributes.

The OPN consists of an adapted salesname plus five additional digits describing the product in more detail.

Because special characters (e.g. commas, dots or dashes) can be disturbing, the OPN will not contain any special characters. That means that the adapted salesname is not equal to the regular salesname. For microcontroller products the adapted salesname will never show the "SA" prefix and the temperature identifier (third digit in the salesname) is moved to the end of the adapted salesname. In very few cases salesnames also had to be adapted slightly in addition to the deletion of special characters due to a maximum length of the OPN of 24 digits.

The OPN shows the RoHS status, the halogen status, the totally lead free status, the functional packing type and size as well as the moisture protection packing. Additionally you can see product variants in the last two digits: Every time a product doesn´t differ in its salesname or the attributes encoded in the OPN (RoHS, Halogen, Packing Type, Moisture Protection Packing and Packing Size), the designator increments.

The first OPN digit encodes RoHS, Halogen and totally lead free status, the second digit shows the combination of packing type and moisture protection packing and the third digit describes the packing size (e.g. 180mm reel or 330mm reel). Every attribute is shown by only one digit (e.g. 180mm = S).

The last two digits identify product variants.

There can be many reasons why a salesname has several ordering codes. To mention just a few examples: Customer specific versions, special test versions, ROM codes, different wafer thicknesses, different temperature ranges, different bonding wires etc. It is simply not possible to cover all of these reasons in a descriptive identifier.

Please refer to this answer if you want to know how to determine differences between designators.

Most of the differences can be found in the Product Change Notification (PCN). If you can´t find the difference between OPNs (their designators) contact your sales person, call us at 00800 951 951 951 or write an email to support@infineon.com.

The OPN is limited to 24 digits.

You can not only see the product and its attributes as you can in the salesname but also information about the RoHS status, the halogen status, the totally lead free status, the functional packing type and size as well as the moisture protection packing. You can also distinguish other product variants based on the designator. 

The descriptive nature of the OPN and its order relevant level makes it easier to communicate: Talking about SP numbers is not convenient as they are simply numbers. Talking about Salesnames is not sufficient because one salesname can have several ordering codes.

Yes, every productive product (except for Engineering Samples) has an OPN.

No. The SP number is a vendors part number. Please talk to your sales contact if you plan to replace the SP# with the OPN.

In general - yes. The salesname can also only be used as a Customer Part Number because it is not unique. That means an order with the Salesname also needs to be translated into an SP number. Additionally it is possible that there are several SP numbers for one salesname which would increase the communication effort to find out the right SP number.

The OPN is shown on the Barcode Packing Label in the 2D barcode and it is shown in the type list of PCNs, PDs and Infonotes. If you use the OPN as your Customer Part Number (You order with a part number different from the SP number) then the OPN is shown on all documents that currently display the CPN: Invoice, Packing List, Order Confirmation, Debit&Credit Notes, Dispatch Note etc.

Not yet in a form readable for the human eye. It is shown in field 50P in the 2D barcode (data matrix code).

No. The datasheet is based on an aggregate level. It is possible that one datasheet is valid for several SP Numbers or several Salesnames. Additionally new OPNs (new SP numbers) are created too frequently to update datasheets.

The OPN is used as a customer part number (customer specific product name). For ordering purposes you tell us the OPN and we link it internally to the corresponding SP number. Now every time you order with the OPN we know the corresponding SP number.

If you would like to switch from your existing identifiers to the OPN, please contact your Infineon sales person.

None of the official product names Salesname, SP number or MA number are replaced. However, several years ago we introduced the proposed customer part number (pCPN) which will be replaced by the OPN.

You can keep ordering with the pCPN because we still maintain the link between your pCPN and the SP number. However, we will not provide you with the pCPN in pricelists or any other document or system anymore.

We strongly recommend to use the OPN for ordering or as your internal identifier instead of the pCPN. If you want to switch to the OPN, please contact your Infineon sales person.

Yes, except for Engineering Samples all Samples have an OPN.

Not necessarily. If a sample for product that comes on a 330mm reel is ordered it does not usually come on the reel itself. 

Additionally it is possible that some sample attributes do not match the OPN attributes (e.g. OPN shows green but sample is grey).

No, Engineering Samples do not have an OPN.

Yes, Kits and Boards are marked with the OPN suffix "TOBO1…9" or “TOBP1…9”.
