I am looking to replace the TAC card on the Sprint Protege Phone system.

Does anyone know where I can find one?

Wouldn't find the card I am looking for.

Do you know if the CSB board always come with the daughter card?

No.

The MAT CODE for a CSB is 436550. And the MAT code for the TAC card is 436368.

The two parts generally are not sold as one product.

If you use the Material Code number...hopefully you cannot go wrong.

You can try https://www.kingtechnologies.com for parts.

They might have the parts...but they are a bit shy on tech support.
