PDF page 2, table row 12. Original manufacturer header DELTA; original cell SI84; 3L dimensions L x W x H (mm): 7.8*7.0*3.5. Unmarked: publisher claims same specification and 3L can replace competitor; directional claim only. Historical 2024 chart; verify current specifications. Series/family selection reference only, not a complete ordering code or drop-in guarantee. Verify inductance, tolerance, dimensions, DCR, current, shielding and current manufacturer datasheets. Bidirectional discovery does not imply symmetric technical interchangeability; no transitive equivalence or series expansion.

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.
