水龙头阀芯同尺寸不同形状的替换件兼容性难以自行判断

来源证据

提问者更换浴室混合水龙头阀芯时，新阀芯尺寸相同但形状与旧件不同，商店口头告知可正常使用，提问者不确定是否应使用该替换件。

I recently replaced the cartridge in a mixer faucet in my bathroom. The new cartridge (Photo B), although it has the same dimensions, does not have the same shape as the old one (Photo A). The store told me that this is not a problem and that I can use it anyway. Should I use it, or should I only use a cartridge with the same shape as the original one?enter image description here
