AT2401C is a 2.4 GHz QFN-16 RF front-end module. Similar FEMs exist, but none is proven pin-compatible from the catalog data.

AI replacement insight

Electrical riskhigh

PA, LNA, NF, and supply must match.

Package riskmedium

Some QFN-16 options are 4x4 or 2x2.

Firmware riskmedium

Control pins and timing may differ.

Sourcing riskmedium

One candidate is discontinued.

Can it be replaced directly?

No direct pin-compatible replacement is proven.

Best replacement path

Start with 8TR8201 for package form, then verify pinout and RF tables.

Main risk

Unverified pinout and PA/LNA performance.
