The Russian component retailer website lists these parts as potential replacements with similar electrical parameters. Always check pin configuration and schematics before soldering:
The STK411-210E does not include onboard DC-offset speaker protection. Designers should always include an external protection circuit utilizing a relay and a dedicated protection IC (such as the UPC1237). This prevents catastrophic DC voltage from reaching and burning out the connected speakers if the hybrid IC suffers an internal short circuit.

Uses IMST substrates for superior heat dissipation, reducing the risk of thermal runaway. Stk411-210e Datasheet
is a dual-channel (stereo) thick-film hybrid audio power amplifier IC engineered for high-fidelity audio equipment. Packaged in a compact, , this component combines Sanyo's proprietary insulated metal substrate technology (IMST) to integrate passive and active components onto a single high-efficiency thermal substrate. This technical analysis breaks down the STK411-210E datasheet, covering pins, operating specifications, and application designs. Technical Specifications
Class-H technology allows the device to switch between low and high voltage rails. This reduces power dissipation during low output periods and improves overall thermal efficiency.
