PDF page 2, table row 8. Original manufacturer header ABC; original cell *SR0403-L; 3L dimensions L x W x H (mm): 4.5*4.0*3.2. Source star: electrical characteristics differ; no general replacement claim. 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.
