AI Summary	SMNR4020-68UH by Shun Xiang Nuo: 620mA 68uH ±20% 600mA 1.38Ω SMD,4x4mm Fixed Inductors .	Würth Elektronik's WE-LQC series 74404042680 is a resin-shielded SMT power inductor in the identical 4020 footprint. It offers lower DC resistance (0.84 Ω max) for improved efficiency, though its rated current is 0.54 A compared to the original's 0.62 A. Direct drop-in footprint and dimensions (4.0 mm x 4.0 mm x 2.0 mm) Lower maximum DCR (0.84 Ω vs 0.95 Ω) reduces resistive power loss Slightly lower rated current (0.54 A vs 0.62 A max)	TDK's VLS4020CX-680M-H is an automotive-grade magnetic shielded power inductor in an identical 4.0 mm x 4.0 mm x 2.0 mm SMT package. It provides comparable saturation current handling (0.65 A max) but features a higher maximum DCR (1.36 Ω). Direct drop-in footprint and dimensions (4.0 mm x 4.0 mm x 2.0 mm) Automotive grade (AEC-Q200 qualified) with high thermal reliability Higher saturation current capability (0.65 A Isat max / 0.72 A typ) Higher maximum DC resistance (1.36 Ω vs 0.95 Ω)

You searched one part. Parter watches your whole BOM.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
