393C

393C is not a single, universal item but a designation used across various catalogs and part-number schemes to identify a product, component, or edition. Its meaning depends on the context and the issuing organization, so a given code can refer to different things in different industries.

In electronics and electrical components, 393C can appear as a model or variant code within a family of devices such as sensors, amplifiers, or semiconductors. The exact specifications—such as voltage, current, package type, or tolerance—are defined by the manufacturer in the datasheet, so the same code may map to different parts from different suppliers.

In automotive and mechanical applications, 393C may designate a sensor, actuator, connector, or housing. As with electronics, the precise item depends on the supplier’s catalog, and correct identification typically requires cross-referencing the full part number with the vehicle or equipment fitment and the supplier’s documentation.

In aviation and aerospace, alphanumeric codes like 393C can appear in parts manuals or service catalogs to identify spare parts or service kits. The code usually corresponds to a registered part number in the aircraft’s maintenance documentation, and verification involves matching the code to the correct aircraft model and revision.

Identification and verification best practices include consulting the full part number printed by the supplier, checking the appropriate datasheet or parts catalog, and considering the industry and manufacturer context. If ambiguity remains, contacting the supplier or requesting a cross-reference can help confirm the exact item designated by 393C.
