nVent HOFFMAN AST283R has 1 recorded cross-reference match across 1 manufacturer. Research equivalent, alternate or similar parts using the listed candidates, and check their source notes before selecting a replacement.
nVent HOFFMAN AST283R versus Hammond Manufacturing CST273:
Source enclosure manufacturer printed as Hoffman; resolved specifically to the nVent HOFFMAN enclosure business, distinct from an unresolved filter-source label. Hammond E6 guide, PDF page 12, column 2, printed E6 destination page 309. Source enclosure/accessory: Hoffman AST283R; source panel field: N/A; Hammond destination: CST273. Printed comment: none. Hammond warns that products may differ; Functional Cross specifically allows dimensional or construction differences. The panel field and comment are retained rather than assuming equal supplied contents. Qualified manufacturer-listed enclosure/accessory comparison, not an independently verified drop-in replacement. Verify current drawings and exact revisions, usable internal and external dimensions, mounting-hole positions, panel/cutout shape and dimensions, allowable panel thickness, retention hardware, door swing/hinges/latches, cable-entry/knockout positions, material/finish, gasket, environmental NEMA/IP rating, thermal limits and safety approvals. A changed panel cutout, relocated holes or modified mounting does not meet the same-panel requirement; missing mounting evidence remains unresolved. Confirm included versus separately ordered panels/accessories and current availability. No unprinted size, finish or accessory variants inferred. Reverse lookup does not establish reverse replacement approval. Excluded from second-degree inference.
Find additional research candidates through a shared connecting part. Each result is labeled Second-degree candidate · Unverified and shows both recorded source relationships.
Two recorded crosses do not establish a verified equivalent. Compare current specifications, interfaces, ratings, cable requirements and the same PCB footprint or panel fit before substitution. Candidate counts are separate from direct-cross and part totals.

Looking for an equivalent or alternate to nVent HOFFMAN AST283R? The 1 recorded candidate above links to individual part pages and the evidence behind each relationship.
A recorded cross reference does not establish a drop-in replacement. Compare current datasheets, package or mounting dimensions, pinout, electrical ratings and operating conditions for your application. Similar parts can differ in critical specifications.
Counts describe recorded relationships, not stock, sales, testing or independent qualification. Manufacturer-and-part identities remain separate. Indexing dates do not establish current specifications or availability.
Check current manufacturer documents and electrical, mechanical, environmental and application requirements before selecting a replacement.
