WX52F62003 Equivalent & Substitute Parts

Part Overview

The WX52F62003 is a CLOCK SAW OSCILLATOR manufactured by Diodes Incorporated, part of the SaRonix-eCera™ WX series. This XO (Standard) oscillator operates in a SEAM5032 package and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity and procurement planning. The substitute part NX5021E0156.250000 provides an active alternative from the same manufacturer's SaRonix-eCera™ NX series.
