Change of Part Name. Because of the new type IC TC4013BP production, the IC manufacture has changed the name of old type IC TC4013BP to TC4Q13BAP. Old type IC TC4013BP and IC TC4013BAP are interchangeable. Since old type TC4013BP and new type TC4013BP function differently, IC itself can not be substituted. However, this change should not affect the operation of AX80 even when a new TC4013BP is installed. The new type IC can be identified by its Lot Number, added to its Lot Number.
