SSF-LXH4RAYD LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The SSF-LXH4RAYD is an active LED Circuit Board Indicator manufactured by Lumex Opto/Components Inc. This component is a single yellow diffused LED with a 3mm T-1 form factor, designed for through-hole right-angle mounting on printed circuit boards. The part operates at 2.1V with a 20mA forward current and delivers 30 millicandela luminous intensity at a 60-degree viewing angle.

Substitute parts are identified when electrical characteristics, mechanical dimensions, and mounting configurations remain identical across the component family, ensuring direct functional equivalence without circuit redesign or board layout modification.
