ERF-2030 is a 25* watt transistor - therefore it is not just a
replacement but also an UPGRADE to the old Mitsubishi
ERF-2030 is a mechanical drop-in replacement for the 2SC1969,
2SC2166 and 2SC2312.
ERF-2030 has been designed as a TO-220 package with the same
pinout configuration as the 2SC1969, 2SC2166 and 2SC2312 and
requires NO mechanical modifications for most
ERF-2030 is NOT an electrical drop-in replacement for the
2SC1969, 2SC2166 and 2SC2312 because some circuit modification is
required for replacement.
*EKL Components rates the ERF-2030 at 25 watts PEP. This is a
CONSERVATIVE rating! In lab tests and real world modifications, a
single ERF-2030 has produced as much as 40 watts PEP. All results
will vary and are solely determined by the circuit surrounding the
