RS-485/RS-422 transceiver — active production, RoHS non-compliant
The MAX3087EPA is an RS-485/RS-422 transceiver from Analog Devices, designed for balanced differential data transmission in industrial and instrumentation links. A critical BOM-fit note: the device is RoHS non-compliant, meaning it contains lead in the solder terminations or internal construction. This is a deliberate choice for applications that require leaded solder processes — high-reliability military, aerospace, or legacy industrial assemblies where tin-whisker risk or reflow-profile compatibility rules out Pb-free. If your assembly line is RoHS-exempt or runs a leaded profile, this part fits. If you need Pb-free compliance, flag the BOM for a RoHS-compliant alternative.
