Yes. According to Honeywell Installation Bulletin 502, the PS-578 has the same dimensions, mounting holes, and same connectors as the KFS-578A. Both controls have the same tuning functions however the PS-578 adds the ability to enter the 8 digit aircraft Flight ID. The design of each control differs as well as the internal circuitry. Some capabilities of the KFS-578 requiring part number differences were consolidated into single part numbers in the PS-578. The wiring is identical and no change in plug configuration or system wiring is required.
