Yes. DY-120 is designed as a compatible replacement for TSOP38238, with the same 38kHz carrier frequency, demodulated output, and standard pin configuration. It can be integrated into existing remote control circuits with minimal design modification.
In most designs, DY-120 can directly replace TSOP38238 because it follows the common 3-pin infrared receiver package and signal structure. However, final compatibility should always be verified through system testing under actual operating conditions.
The built-in infrared optical filter suppresses visible light and environmental interference such as sunlight and LED lighting. This helps ensure stable signal reception and reduces false triggering in practical applications.
Yes. DY-120 is manufactured with stable production processes and batch consistency control, making it suitable for long-term supply to electronics manufacturers and OEM projects.
Yes. Samples of DY-120 are available for engineering evaluation and project testing, helping customers verify compatibility and system performance before mass production.
