G2R-1-DC24 may serve as a 24V SPDT functional alternative, but coil load and fit need review.
G5V-1-DC24 is a 24V SPDT low-signal PCB relay. Current catalog candidates need FAE review because pinout evidence is missing or key relay parameters differ.
G2R coil power is much higher than target.
Target pin_count and pinout are missing.
No digital firmware interface.
Kept candidate is catalog indexed.
No verified pin-compatible replacement is supported by the provided evidence.
Review G2R-1-DC24 only as a functional 24V SPDT alternative, not as a drop-in.
Pinout and coil-drive load are not verified against the G5V-1-DC24.
