Bourns SinglFuse manufacturer family comparison, PDF page 1, row 30, target group: General Purpose. Page footer: June 2025, e/SF2503. The table lists 459 against Bourns family SF-2410FP-T; these are series, not complete orderable fuse part numbers. No current-rating, voltage, package-count or packaging variants are generated. Source slash-separated competitor family labels remain grouped exactly as printed. Match exact current, AC/DC voltage and interrupt ratings, time-current curve, I²t, inrush/pulse capability, temperature derating, package dimensions and board footprint using current manufacturer datasheets. The automotive-column heading applies only to the indicated Bourns family; it does not transfer AEC-Q200 qualification to the competitor, general-purpose options or every ordering variant. The guide footnote refers to AEC-Q200 Revision E. Family comparison does not establish a drop-in or reverse replacement approval. Excluded from second-degree inference. The source marks this Bourns series as recommended for new designs as of the page date; current lifecycle must still be verified.

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.
459 series comparison
These series references are starting points for comparing product families. Select and verify the complete ordering code.
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.
