Overview
Equivalent
The VS1838B is an IR receiver module. Equivalent alternatives include:
- TSOP38238 (similar specs, 38kHz)
- VS1838 (earlier version)
- TL1838 (compatible)
- IRM-3638 (same function)
- HS0038B (common replacement)
These are pin-compatible and operate at 38kHz. Check datasheets for minor variations in sensitivity or voltage range.
