Murata has placed the LQH31CNR12M03L under a last-time-buy notice — the product status is Last Buy. That means the manufacturer has stopped accepting new orders beyond a final cutoff window; once that window closes, the part is gone from the authorized channel. For a BOM that already carries this 120 nH drum-core inductor, the immediate decision is whether to secure lifetime-buy inventory or qualify a replacement before the last-buy deadline passes. No official successor is listed, so the replacement path is a parametric search — same 1206 footprint, same inductance, similar DCR.
Parametric fit for the 1206 pad
The unshielded design means the magnetic field radiates; keep it away from sensitive traces or other magnetics that could couple noise. Inductance is 120 nH at 1 MHz test frequency, with ±20% tolerance. DC resistance maxes at 112 mOhm, and the current rating is 970 mA — that is the saturation or temperature-rise limit, whichever comes first. Self-resonant frequency is 250 MHz, so it behaves as an inductor well into the VHF band. The ferrite core material gives stable inductance over frequency but saturates harder than an air core at high current; the 970 mA rating already accounts for that.
Sourcing posture for a last-buy part
Because this is a Last Buy status part, it is not available through normal production replenishment. We source it through independent distribution channels — surplus, excess inventory, or last-time-buy allocations — and confirm availability and pricing at quote time against your BOM quantity. If you need a second-source option, the LQH31 series includes other inductance values in the same 1206 package, but the 120 nH value is unique to this order code. A parametric search across the series with the same footprint and similar DCR is the practical next step.
