Is there a pin-compatible replacement for 126RV0139?

While no replacement has been pre-verified as pin-to-pin compatible, parts like Lelon VZH101M1HTR-0810 have nearly identical package dimensions (8mm diameter) and are likely compatible. A land pattern check is required.

What risks should I check before replacing 126RV0139?

Before replacing, verify the candidate's package dimensions (diameter and height) and land pattern match your PCB layout. Also, confirm secondary parameters like ripple current and endurance meet or exceed your application's requirements.
