XDTD-0304-215 is a same-role SMD tactile switch, but pinout and footprint need review.
TS-1185EC-C-D-B is a compact 2-pin SMD SPST-NO tactile switch. Current candidates need footprint and pinout review before use.
Several candidates match 50mA 12V.
Footprint and pinout are not proven.
Passive switch; no firmware impact expected.
Catalog matched, but PDF checks are pending.
No pin-compatible replacement is proven from the provided fields.
Start with XDTD-0304-215 or XDTD-0306-025A, then verify footprint, pinout, and force.
Mechanical fit and pinout are not verified.
