SWT-0.68-377	377 µH	±20%	680 mA	1 Ohm	Unshielded	Toroidal	Iron Powder	Through Hole	-40°C ~ 125°C	Radial, Horizontal (Open)	0.591" L x 0.591" W (15.00mm x 15.00mm)	0.346" (8.80mm)	ROHS3 Compliant	REACH Unaffected

Substitute Part Grouping Explanation

For a substitute part in the fixed inductor category, equivalency is strictly determined by matching inductance (377 µH), current rating (680 mA), DC resistance (1 Ohm), shielding (unshielded), core material (iron powder), mounting (through hole), and package or dimensional compatibility. Only parts that meet these explicit parameters are listed as substitutes.
