UNSPSC 32121901: Surface acoustic wave SAW resonator

Surface acoustic wave frequency control devices

UNSPSC 32121901 Surface acoustic wave SAW resonator (Commodity) covers specialized electronic components and control systems that state and local governments procure for utility infrastructure, municipal facilities, and transit operations. Recent solicitations show the code capturing a broader scope than the nominal commodity name suggests: electrical relay systems for power distribution and protection, control panels and motor control centers for pump stations and lift stations, electrical parts and components for maintenance and emergency repair, and standardized electrical distribution equipment for SCADA and facility infrastructure. Issuing bodies include utility authorities, county governments, municipal transit agencies, school districts, and county commissioners' offices. Kissimmee Utility Authority (Florida) solicited SEL 451 and SEL 751 protection relays for aging electrical system replacement under a sole-source procurement (RFQ SS26054SH, due August 24, 2026). Hillsborough County Board of County Commissioners (Florida) issued a competitive ITB for pump station control panels and enclosures with an estimated two-year value of $3.66 million (ITB2600393, due September 29, 2026), and separately solicited Schneider brand electrical components for SCADA control panels over two years valued at $519,787.19 (ITB2600277, due June 18, 2026). Trinity Metro (Tarrant County, Texas) established an IDIQ contract for electrical materials covering maintenance, repair, renovation, and emergency operations across facilities (IFB26T035, due August 20, 2026). Gwinnett County, Georgia sought annual contracts for ballasts and capacitors for the Parks and Recreation Department (PA028-26, due June 12, 2026).

Geographic activity clusters in Florida (Kissimmee, Hillsborough County, Bay County, Tampa, and the broader Gulf Coast region) and Texas (Tarrant County, Arlington, Fort Worth), with secondary activity in Georgia and multistate cooperative purchasing through Sourcewell. The code shows consistent demand from utilities and county infrastructure departments rather than K-12 schools or smaller municipalities. Representative recent opportunities include Hillsborough County's pump station control panel procurement (estimated $3.66 million, ITB, competitive sealed bids, response due September 29, 2026) and Kissimmee Utility Authority's SEL relay replacement (sole-source quotation, response due August 24, 2026). The opportunities reflect infrastructure maintenance cycles, system standardization requirements, and long-term renewal commitments rather than sporadic or emergency-driven demand.
