Is the PRM240-R2 a direct drop-in replacement for my current LT1110 / PRM240 layout?

Answer

Yes, for pluggable U.FL configurations. The PRM240-R2 (Part Number: 453-00418) features the exact same pluggable form factor (4 mm x 39 mm x 25 mm) and pinout as the legacy pluggable LT1110/PRM240 U.FL variants. If your design utilizes an surface-mount (SMD) or integrated trace/chip antenna variant, please contact our engineering team to review pinout and mechanical adaptation options for the pluggable U.FL unit.
