UNSPSC 32111615: Small signal field effect transistor

UNSPSC 32111615 Small signal field effect transistor is a Commodity code for specialized electrical components that state and local governments source primarily through utility infrastructure upgrades, wastewater and water treatment facility modernization, and facility control system replacements. Recent solicitations show that procurement under this code encompasses not field-effect transistors in isolation but rather integrated electrical protection relays, motor control centers, SCADA components, and related enclosures that require tight interoperability with existing systems. The issuing bodies include municipal utility authorities, county public works and utility departments, and transit authorities; repeat buyers include Hillsborough County (Florida), which has issued multiple ITBs for electrical components and control panels. The work being solicited involves replacement of aging protection and control infrastructure where standardization and compatibility with existing fleet systems drive procurement decisions, often resulting in sole-source awards or brand-specific component sourcing when legacy system lock-in is present.

Recent opportunities span Florida and Texas. Kissimmee Utility Authority solicited SEL 451 and SEL 751 protection and feeder relays (RFQ, response date August 24, 2026) on a sole-source basis, citing the need for full compatibility with existing relay fleet and SCADA infrastructure without redesign. Hillsborough County Board of County Commissioners issued an ITB for pump station control panels and enclosures estimated at $3.66 million over two years (ITB-26-00393, response date September 29, 2026), requiring UL 508A certification and NEC compliance, with unit prices ranging from approximately $21,000 to $112,000 depending on electrical configuration. Hillsborough County also solicited ongoing Schneider brand electrical components for SCADA control panels (ITB-26-00277, estimated $519,787.19 over two years, response date June 18, 2026), restricting responses to authorized Schneider distributors and requiring all line-item submission. The City of Tampa requested quotes for a Zenith ATS solenoid supply and installation (RFQ 26P00389, response date June 19, 2026), and Gwinnett County, Georgia requested ballasts and capacitors on an annual contract (response date June 12, 2026). Geographic concentration is strongest in Florida and Texas, with secondary activity in Georgia.
