SP61

SP61 is a designation used across multiple industries to identify model numbers, parts, or project identifiers. It does not refer to a single, widely recognized object or entity, but to several distinct uses that share the same alphanumeric code.

In technology and electronics, SP61 has appeared as a model number for components such as image sensors, power regulators, or interface chips produced by different manufacturers. In these contexts, the code is usually accompanied by additional digits or letters that specify performance classes, packaging, or generation, making SP61 one element of a larger part number.

Within public transport and rail networks, SP61 has been used as a designation for specific vehicle models or configurations. Examples include buses, trams, or locomotives assigned internal codes by operators. Because the SP prefix can have different meanings (for example, “Special Purpose” or “Standard Passenger”) the exact interpretation depends on the operator, country, and era.

In historical military procurement and industrial catalogs, SP61 has appeared as a project or catalog code. Interpretations vary by country and period, and many records use SP61 alongside other identifiers. As a result, identifying a precise object requires cross-checking the context and source documentation.

In miscellaneous uses, SP61 may appear as a stock-keeping unit, serial code, or inventory label without implying a specific product.

Because SP61 denotes multiple, unrelated items, consult source material for the intended reference.
