TSOP4838 Pinout Equivalent

1：Overview of the TSOP4838：

TSOP4838 is a particularly practical component, specifically designed for receiving infrared signals. Whether it’s a TV, air conditioner, or a toy car remote control, as long as the infrared signal operates at 38kHz (the most common frequency for remotes), it can accurately capture it. It includes an infrared filter that automatically blocks interference from sunlight and ambient light, ensuring accurate signal recognition even under strong lighting conditions. The official range is said to be up to 45 meters, though actual performance may vary depending on the environment. However, it is more than sufficient for everyday household use or small-scale control.

3：Alternative model recommendation

XL-IRM0038Q：XL-IRM0038Q is a ‘signal little ear’ designed specifically for infrared remote control. In simple terms, it’s the core module that allows ordinary devices to understand remote control commands! It functions similarly to the TSOP4838 we discussed earlier but can be considered an ‘upgraded version’—for example, it has a longer reception range (up to 15-18 meters according to the manufacturer), stronger interference resistance, and some models even come with iron casing shielding to filter out environmental light interference from sources like sunlight and LED lights.

The IRM-H638T/TR2：The IRM-H638T/TR2 from Everlight is a ‘mini signal translator’ designed to convert infrared commands from remote controls into electrical signals that circuits can understand. Similar to the TSOP4838 and XL-IRM0038Q we discussed earlier, it excels at capturing signals in complex environments, such as strong kitchen lighting, Wi-Fi router interference, or even motor noise in factories. It automatically filters out 90% of the noise, retaining only the 38kHz remote control commands.

IRM-3638T：IRM-3638T is like a highly resistant ‘signal bodyguard,’ especially suitable for stable operation in environments with strong light, Wi-Fi interference, or industrial noise, such as LED lights in the kitchen, motor noise in factories, or even outdoor sunlight. It can automatically filter out 90% of the noise and retain only the 38kHz remote control commands.

XS-PT02H07-600：XS-PT02H07-600 is an industrial-grade infrared receiver module with core functions similar to those of previously mentioned TSOP4838 and IRM-H638T/TR2, but it may feature unique designs in terms of interference resistance, packaging, and application scenarios.
