第二代CR200J与上一代相比有诸多改进。首先，车体断面改为鼔型，车厢宽度和坐席与CR300和CR400系列相同，由3105 mm加宽至3360 mm，坐席宽度也将大幅度加宽，车辆间距缩短到800mm，风挡改为对波橄榄型双层折棚风挡，提高车体气密性，拖车空调机组原有一车两台的改为一台，车厢高度仍保持4433 mm，是目前国内最“胖”的单层列车，另外，虽然车体宽度增加，但整体重量控制相较于第一代更优。座位数及布局与CR200J第一代保持不变，但坐席宽度有所增加，且乘客使用的充电插座由坐席下部改为与CR300/400系列相同的位置，即二等座插座位于座椅接缝处下方，一等座位于中央扶手。
在安全性和舒适性等方面还有多项改进，拖车控制网络由LON网改为Ethernet以太网，网络控制系统提升互联、互通和互控功能，动力车、拖车、控制车故障报警信息互通，形成统一的列车监测信息网。通讯、重联连接器采用矩形连接器，同时所有连接器插接采用螺栓固定方式，DC600V使用2个矩形连接器，正负极分开。车门由电控气动改为电控电动塞拉门，取消低站台停靠功能，取消站台补偿器。
