Difference between Sony USB Type-C (UCB20 17W17 & 16W35)?

[LevsMAN]

Hello

I've just received my Sony UCH-12 Quick Charger and it was supplied with a UCB20 cable but I noticed on the little ribbon that the digits and letter at the end are different (16W35). 

I don't even know what these mean and of course is why I am here but my XA1 Ultra cable that was originally included is 17W17, does it make any difference using these cables it's just something I've seen before on the Micro USB cables...

@LevsMANthose numbers simply indicate when the accessory was made. 16W35 means it was made in the 35th week of 2016.

Thanks for pointing this out man, something I've never thought to ask but did notice on the connector for the phone is slightly different inside. 

Anyhow, thanks once again and now of course enjoying quick charging on the XA1 Ultra. 50 mins to 100% from 50% so it seems it's cut off slightly over an hour compared to the UCH-20 which was originally supplied 👍😉
