100nF X7R value matches, but 1812 SMD requires PCB redesign.
CT4-0805B104K500F3 is a radial 100nF 50V X7R MLCC. Current candidates need review; none is proven pin-compatible.
Value matches only for kept SMD parts.
SMD is not radial 5.08mm.
Passive capacitor.
PDF checks are pending.
No pin-compatible replacement is supported by the provided evidence.
Search for a radial 5.08mm, 100nF, 50V or higher, X7R, ±10% MLCC.
The kept candidates are SMD parts and need PCB redesign.
