UNSPSC 32111500: Diodes

UNSPSC 32111500 Diodes is a Class code covering electrical components and parts that state and local governments procure for utility infrastructure, facility maintenance, transit operations, and water treatment systems. Recent solicitations under this code show purchasing focused on specialized electrical components including protection relays for utility SCADA systems, electrical equipment parts for schools and municipalities, control panel enclosures and motor control centers for wastewater and water systems, ballasts and capacitors for parks departments, and standardized Schneider Electric components for control systems. Issuing bodies span utility authorities, county boards, school districts, cities, and transit agencies. Kissimmee Utility Authority (Florida) issued a sole-source RFQ for SEL 451 and SEL 751 protection relays with response due August 24, 2026; Northside Independent School District (Texas) posted an IFB for electronic equipment parts and repairs due September 24, 2026; Hillsborough County (Florida) solicited pump station control panels and enclosures under ITB-26-00393 due September 29, 2026 with an estimated value of $3.66 million; and Gwinnett County (Georgia) requested quotes for ballasts and capacitors due June 12, 2026.

Recent activity concentrates in Florida (Kissimmee, Hillsborough, Tampa, Bay County) and Texas (Northside ISD in San Antonio, Trinity Metro in Tarrant County, City of Arlington, City of Fort Worth), with secondary activity in Georgia. The geographic spread reflects procurement driven by utility infrastructure upgrades, water system standardization, facility maintenance programs, and transit operations. Representative opportunities show direct replacement of aging equipment requiring exact compatibility (Kissimmee's SEL relays), blanket annual purchases of standardized parts (Northside ISD's electronic equipment contract, Hillsborough's Schneider components ITB valued at $519,787.19 over two years), and specialized fabrication (Hillsborough's control panels at $3.66 million over two years). Sourcing through cooperative purchasing vehicles like Sourcewell also appears, though law enforcement equipment RFP #061626 is outside the diodes code's core scope.
