UNSPSC 32121500: Capacitors

UNSPSC 32121500 Capacitors is a Class code covering electronic components and subassemblies that state and local governments procure for electrical system maintenance, control panel fabrication, and equipment replacement across utility, transit, school, and county operations. Recent solicitations show state and local buyers acquiring capacitors as part of broader electrical equipment and parts contracts rather than as standalone line items; the code captures both discrete capacitor purchases and integrated capacitor components within larger control system assemblies. Gwinnett County, Georgia recently solicited approximately 200 units annually of Aerovox Z74S5232NN capacitors or approved equivalents for the Parks and Recreation Department on an annual contract basis, with quotes due June 12, 2026. Hillsborough County, Florida has issued multiple related electrical component contracts—including ITB-26-00277 for Schneider Electric components valued at $519,787.19 over two years and ITB-26-00393 for pump station control panels valued at $3.66 million over two years—where capacitors appear as integrated subcomponents within larger fabricated assemblies. School districts and transit authorities also participate; Northside Independent School District in San Antonio issued a broad IFB for electronic equipment, parts, repairs, rentals, and services due September 24, 2026, and Trinity Metro in Tarrant County, Texas, established an IDIQ electrical materials contract for facility maintenance across stations and administrative buildings. Issuing bodies mix county governments, municipal utilities, school districts, and transit authorities, with repeat activity from Hillsborough County and activity concentrated in Florida and Texas.

Recent opportunities reflect two procurement patterns: direct capacitor purchases bundled into larger electrical parts contracts, and capacitors embedded in engineered control systems where compatibility and interoperability are critical. The Kissimmee Utility Authority sole-source procurement (SS26054SH, due August 24, 2026) demonstrates the latter—KUA specified SEL 451 and SEL 751 protection relays with integrated capacitor and control components that must interoperate with existing SCADA infrastructure without redesign. Hillsborough County's pump station control panel contract required UL 508A-certified fabrication shops to build cabinets containing capacitors and other components in multiple electrical configurations (480/277 volt and 240/120 volt) for delivery within one month of purchase order, with unit prices ranging from approximately $21,000 to $112,000 depending on specifications. Gwinnett County's straightforward annual capacitor buy (1500W metal halide ballasts paired with capacitors, approximately 200 units annually) represents the simpler end of the spectrum. Geographic concentration appears strongest in Florida (Hillsborough, Kissimmee, Bay County, Tampa, and numerous control panel and electrical infrastructure projects) and Texas (Gwinnett County activity, Northside ISD, Trinity Metro, City of Arlington, City of Fort Worth), with secondary activity in Georgia and Washington state through cooperative purchasing vehicles like Sourcewell.
