VCNL4100 Equivalent & Substitute Parts

Part Overview

The VCNL4100 is an optical sensor designed for ambient light detection at 550nm wavelength with I2C digital output interface. This component integrates proximity detection capability in a compact 10-SMD surface mount package. The VCNL4100 is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing production and new design implementations. Substitute parts must maintain electrical compatibility, mechanical fit, and output protocol consistency to ensure direct replacement capability.
