No, the IVA-81D only directly replaces the IVA-81A and IVA-81C. The IVA-81A/C/D are capable of displaying traffic advisories (TA), resolution advisories (RA), and vertical speed. The IVA-81B only displayed RAs and vertical speed.

The IVA-81D could be used in place of the IVA-81B. However, in most cases, a change would need to be made the original aircraft Type Certificate or Supplemental Type Certificate in addition to the installation being reconfigured to display TAs on the IVA-81D.
