1517C

1517C is a designation used in multiple industries to identify a specific variant within a product line. There is no single, universal definition for 1517C; the exact meaning depends on the company, product category, and cataloging system.

In electronics and hardware, 1517C has appeared as model numbers for sensors, boards, and modules. The trailing letter C commonly signals a revision or variant, such as a particular pinout, enclosure, or firmware baseline.

In automotive and industrial equipment, 1517C is used as a part number for assemblies, control modules, or kit components, with the suffix indicating a revision or configuration. The designation is typically found in supplier catalogs and procurement documents rather than in consumer-facing product pages.

In software and data management, 1517C can function as a build tag or version identifier within non-standardized labeling schemes, often internal to a vendor or project. Such usage is less common and not part of formal software versioning conventions.

Etymology and interpretation: The digits 15 and 17 may reference series, production year, or internal numbering, while the C indicates a revision or subclass. Because the code is not standardized, the exact specification of 1517C requires consulting the issuing organization’s documentation or catalog.
