### Fields

#### `concrete` · [`Boolean!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/boolean.md) non-null scalar

Indicates whether this part variant is a concrete (fully specified) part.

#### `description` · [`String!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/string.md) non-null scalar

Descriptive text explaining the part variant.

#### `deviceFamily` · [`String!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/string.md) non-null scalar

Stable family key (e.g. "RA", "RAFW", "RX"), derived from the backing device's platform. Matches DmDeviceFamily.key and deviceFamilyKey. Empty when the platform is unknown (e.g. a non-concrete grouping node with no device).

#### `display` · [`String!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/string.md) non-null scalar

Formatted display string for the part variant.

#### `friendlyPartialMpn` · [`String!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/string.md) non-null scalar

Human-friendly display of the partial MPN.

#### `level` · [`Int!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/int.md) non-null scalar

Hierarchy level of the part within the family.

#### `manufacturer` · [`String!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/string.md) non-null scalar

Manufacturer or vendor associated with the part.

#### `mcuPartDetails` · [`DmMcuPartNumberModel`](https://altiumdeveloper.github.io/platform-api-docs/reference/renesas-preview/types/objects/dm-mcu-part-number-model.md) object

MCU part number details parsed into structured properties.

#### `partialMpn` · [`String!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/string.md) non-null scalar

Partial manufacturer part number pattern identifying a family subset.

#### `vendor` · [`String!`](https://altiumdeveloper.github.io/platform-api-docs/reference/common/types/scalars/string.md) non-null scalar

Silicon vendor, e.g. "Renesas", derived from the backing device's platform. Empty when the platform is unknown.

#### Deprecated

#### `raPartDetails` · [`DmRaPartNumberModel`](https://altiumdeveloper.github.io/platform-api-docs/reference/renesas-preview/types/objects/dm-ra-part-number-model.md) **DEPRECATED** object
