UNSPSC 32141020: Frequency converting tube

A vacuum tube for frequency conversion that undertakes both actions of local oscillation and mixture together in a single vacuum tube.

UNSPSC 32141020 Frequency converting tube is a Commodity code that covers electronic components used in signal conversion and transmission equipment, though recent state and local procurement activity under this code shows limited relevance to the nominal product scope. Northside Independent School District in San Antonio issued IFB 2026118 in September 2026 for electronic equipment, parts, repairs, rentals, and services with a response deadline of September 24, 2026 — a broad category that encompasses general electronic goods and maintenance rather than specialized frequency conversion devices. Sourcewell, the Minnesota cooperative purchasing vehicle, posted RFP 061626 in May 2026 for law enforcement equipment serving multiple Washington counties and participating entities nationwide, with a June 16, 2026 deadline, though law enforcement equipment procurement similarly diverges from the specific component focus the code nominally describes. The issuing bodies across recent opportunities span school districts and cooperative purchasing consortia, reflecting the diversity of state and local procurement channels rather than concentration among particular jurisdiction types.

Activity appears concentrated in the upper Midwest and Southwest, with Sourcewell's multi-state cooperative reaching across Washington and beyond, and Northside Independent School District anchoring Texas procurement. The mismatch between the code's specific product definition—frequency converting tubes—and the scope of actual solicitations posted under it suggests that the code may be incorrectly applied in state and local procurement systems, or that these opportunities represent only a small fraction of activity tagged to 32141020. Business development professionals should verify code alignment with the issuing body's procurement office before pursuing opportunities tagged to this Commodity code, as the recent record shows little evidence of demand for specialized frequency conversion components in state and local markets.
