What risks should I check before replacing GAQY212GS?

The main risks are electrical. Ensure the replacement's load voltage and current ratings meet or exceed the original's 60V/0.8A. Also, check on-resistance, as a higher value can increase power loss. Finally, confirm the package and pinout match.

GAQY212GS Alternatives, Datasheet & Cross Reference | SUPSiC

SUPSiC GAQY212GS is a 60V, 0.8A solid state relay in an SOP-4 package. Several likely pin-compatible upgrades with higher current ratings are available from the same manufacturer.

AI replacement insight

Electrical risklow

Multiple upgrades with better current and resistance are available.

Package risklow

All strong candidates are in the same SOP-4 package.

Sourcing risklow

Multiple suitable alternatives exist from the same manufacturer.

Can it be replaced directly?

Yes, GAQY212GSX is a near-identical replacement with a slightly higher current rating (1.0A) and lower on-resistance.

Best replacement path

Upgrade to GAQY212G2S for significantly higher current capacity (1.8A vs 0.8A) and lower on-resistance in the same package.

Main risk

The main check is confirming the pinout from the datasheet, although it is very likely identical for same-family parts from SUPSiC.

Recommended alternatives

A near-identical alternative with higher current (1.0A) and lower on-resistance (0.18Ω) in the same package.
