UNSPSC 32111600: Transistors

UNSPSC 32111600 Transistors is a Class code that spans electrical and electronic components used in protection, automation, control, and power distribution systems for utility, municipal, and transit infrastructure. State and local governments procure under this code primarily specialized industrial relays, control components, and associated electronic parts for electrical system modernization, replacement, and emergency repair—not consumer electronics or discrete semiconductor transistors. Recent solicitations show utilities and special districts sourcing protection relays, motor control centers, electrical components, ballasts, capacitors, and solenoid assemblies for SCADA integration, pump station automation, lift station systems, and facility power management. Issuing bodies include utility authorities, county commissioners, independent school districts, municipal water and transit authorities, and parks departments. The code captures both blanket standing supply contracts and single-unit emergency replacements, with vendors often required to hold manufacturer authorization, UL certification, or specific product-line credentials rather than general electrical supply capability.

Recent activity concentrates in Florida and Texas, with secondary representation in Georgia and Washington state. Kissimmee Utility Authority issued a sole-source quotation for SEL 451 and SEL 751 protection relays in September 2026 (RFQ SS26054SH, due August 24, 2026); Hillsborough County Board of County Commissioners posted a competitive ITB in September 2026 for pump station control panels and enclosures with a $3.66 million two-year estimated value and a requirement for UL 508A certification (ITB-26-00393, due September 29, 2026); Northside Independent School District issued an IFB for electronic equipment, parts, repairs, and services in September 2026 (IFB2026118, due September 24, 2026); and Hillsborough County issued an earlier ITB in June 2026 for Schneider brand electrical components with a $519,787.19 estimated value over two years (ITB-26-00277). Additional opportunities include Gwinnett County Parks seeking ballasts and capacitors in June 2026, the City of Tampa requesting a solenoid supply and installation in June 2026, and Trinity Metro establishing an IDIQ electrical parts contract in August 2026. Geographic activity shows Hillsborough County and the greater Tampa Bay area as repeat solicitors.
