The RUILON 2R3000T-8 is a 2-electrode, 3000V Gas Discharge Tube (GDT) in an 8x6mm through-hole package for high-voltage surge protection. Alternatives must match the spark-over voltage and package.

AI replacement insight

Electrical riskhigh

Spark-over voltage is a critical parameter that dictates function. Mismatch is high risk.

Package risklow

The 8x6mm through-hole package is common, and several candidates match it.

Can it be replaced directly?

No confirmed direct drop-in replacement exists, but 2R3600T-8 is a very strong functional alternative with the same form factor and current rating.

Best replacement path

The RUILON 2R3600T-8 is the best path, offering a slightly higher voltage rating in the same package from the same manufacturer.

Main risk

The primary risk is mismatching the DC spark-over voltage, which defines the circuit's protection level. A lower voltage can cause false triggering.
