This is our chip, which I have marked TCR #N1637

Looking at the chipguide I see this chip...marked TCR #V2553

Is it the same chip (I think they're probably the same color)? I'm using a 2012 TCR and it doesn't even have V2553 as an option (though it does have V2554)....is that an updated number? Or a typo on the chipguide? Or a figment of my imagination? I like to think that my chips aren't cataloged because of questions like this... (Though it's more likely that they aren't cataloged because I'm easily distracted from my "tasks"! lol! )

Thanks!
