Most semiconductor manufacturers offer multiple versions of a device to meet different applications and operating environments. While the underlying silicon may be similar, a major factor in product compatibility is variation in packaging, environmental qualifications, or performance specifications.
Using the right OPN helps companies:
The long development cycles and high quality requirements of semiconductor products make accurate OPN records critical.
The format of an OPN varies by manufacturer, but most contain information identifying:
They each help to identify one version of a component from another, so the right product can be ordered and installed.
While they are sometimes used interchangeably, a Manufacturer Part Number (MPN) and an Orderable Part Number are not always the same.
The MPN may represent the core semiconductor device or product family, while the OPN typically defines the specific configuration available for purchase. For example, a microcontroller might have only one base device designation, but multiple OPNs that specify different package styles, temperature grades, or shipment formats.
Knowing the difference helps procurement teams source the correct component and ensures that engineering requirements will be met.
Small differences between component variants can lead to big problems downstream. Choosing the wrong package type or qualification grade can lead to assembly problems, compliance issues, production delays, or product redesigns.
Organizations Benefit From Effective OPN Management:
As semiconductor supply chains grow more complex, visibility into approved OPNs is more critical than ever for operational efficiency and risk mitigation.
Product manufacturing is based on the Bill of Materials (BOM). The correct OPN is included so that sourcing teams buy the exact component approved by engineering.
When components change, organizations need to assess the impact on quality, performance, compliance, and manufacturing processes. Connecting OPNs to engineering change orders and approved component records enhances traceability and lowers the risk of unauthorized substitution.
Effective OPN management also helps organizations maintain consistency across product revisions and manufacturing locations.
Product lifecycle management (PLM) systems offer a unified environment for managing component data including OPNs, approved manufacturers, supplier information, and lifecycle status.
By managing OPNs within a PLM system, organizations can:
For semiconductor companies, incorporating OPN management into product development processes enhances collaboration among engineering, sourcing, quality, and manufacturing teams.
The manufacturer assigns an Orderable Part Number to each version of a component that is available for purchase. This number describes the package type, performance grade, temperature range, qualification status, and other details.
Manufacturers typically provide multiple versions of the same device in order to meet different applications, packaging requirements, environmental conditions and distribution techniques. Each variation has its own OPN.
Using approved OPNs in a bill of materials (BOM) allows procurement teams to source the exact components selected by engineering, minimizing the chance of ordering the wrong or incompatible parts.
PLM software allows teams to more effectively manage OPNs by consolidating component data, controlling approved parts, managing BOMs and changes, and maintaining traceability throughout the product lifecycle.
