MT6825GT-STD is a same-vendor lower-performance angle encoder candidate.
MT6835GT-STD is a 21-bit AMR magnetic angle encoder. No pin-compatible replacement is confirmed from the provided evidence.
Resolution, speed, and accuracy may drop.
Cross-vendor options use different packages.
SPI registers and output setup need checks.
Kept candidates are catalog matched.
No confirmed pin-compatible replacement is available.
Check MT6825GT-STD first only if lower resolution and speed are acceptable.
Pinout and firmware compatibility are not verified.
