UNSPSC 32101521: Radio frequency RF filters

UNSPSC 32101521 Radio frequency RF filters is a Commodity code that encompasses electrical components for power protection, automation, and control systems in utility and infrastructure settings. State and local governments procuring under this code are acquiring specialized electrical equipment including protection relays, motor control centers, electrical components for SCADA systems, and related switching and automation hardware for water utilities, transit authorities, counties, and municipalities. The issuing bodies include utility authorities, county commissioners' offices, transit agencies, school districts, and municipal water treatment facilities. Work solicited under the code ranges from sole-source replacement of aging protection relay fleets fully integrated with existing SCADA infrastructure to open competitive bidding for standardized electrical components on annual or multi-year blanket purchase agreements.

Recent activity appears concentrated in Florida and Texas. Kissimmee Utility Authority issued solicitation SS26054SH (quotation, due August 24, 2026) for SEL 451 and SEL 751 protection and feeder relays on a sole-source basis, with KUA justifying exclusivity through the technical necessity of maintaining compatibility with existing relay platforms and SCADA protocols. Hillsborough County Board of County Commissioners solicited ITB-26-00393 (bids, due September 29, 2026) for pump station control panels and enclosures valued at $3.66 million over two years, requiring UL 508A certification and weekly fabrication capacity of two to four complete units. Trinity Metro in Tarrant County, Texas posted IFB26T035 (proposals, due August 20, 2026) establishing an IDIQ contract for electrical parts supply across facilities and maintenance shops. The City of Bartow, Florida within the same recent window sought proposals for installation of a new Master Lift Station Motor Control Center. Gwinnett County, Georgia requested competitive quotes for ballasts and capacitors on an annual contract (due June 12, 2026), and Hillsborough County sought bids for ongoing Schneider brand electrical components (ITB-26-00277, due June 18, 2026, estimated $519,787.19 over two years). These opportunities indicate steady demand for both sole-source equipment replacement requiring technical interoperability validation and open competitive procurement of standardized electrical components on volume or annual-requirements contracts.
