Lifecycle

Product status believed active within JST XAD series at the time of listing. No public end of life notice observed by Y-IC

Equivalent or alternative models exact drop in replacements depend on the same series footprint shroud and latch geometry. Within JST the XAD family with the same base number B20B-XAD and identical suffix options is the typical like for like option for 20 positions vertical through hole with locking ramp and board guide

Cross family or cross brand parts with similar pitch or pin count may not mate correctly or share the same footprint due to keying shroud and latch differences. For vetted alternates including right angle versions different plating options or other pitch families please contact the Y-IC sales team via our website. We will recommend fully compatible or qualified alternatives based on your mating housing PCB layout current and voltage needs
