BLM15AG601SH1D is a same-size ferrite but needs current and DCR review.
BLM15PX471SN1D is a 470Ω, 1A 0402 Murata ferrite bead. No direct replacement is proven from the reviewed candidates.
current, DCR, and impedance differ
kept parts are 0402
passive ferrite bead
lifecycle data is incomplete
Direct replacement for BLM15PX471SN1D should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Check Murata BLM15PX same-series parts first; reviewed AG/AX parts need derating review.
Most candidates miss the 1A current, 470Ω impedance, or 0.20Ω DCR target.
