End-of-order Wi-Fi 6 Universal (UTP) high-density indoor access point - three radios with the option of dual 5 GHz operation, 4x4 MU-MIMO, ten external RP-SMA antennas, a 2.5 Gigabit Ethernet uplink plus a second Gigabit port for PoE diversity, and 802.3at PoE. The Universal family runs FortiGuard UTP services at the edge and is managed by any FortiGate or by FortiLAN Cloud. New hardware is no longer available from stock; existing fleets stay supported and renewable through 2030. For new deployments the direct successor is the Wi-Fi 7 FortiAP 443K.
The FortiAP U433F is a high-density Wi-Fi 6 (802.11ax) Universal access point built for demanding indoor spaces - large offices, lecture halls, conference centres and busy retail - with ten external RP-SMA antennas for flexible coverage shaping. It is the external-antenna sibling of the internal-antenna U431F. Its tri-radio design runs two 4x4 client radios that can operate as 2.4 GHz + 5 GHz + 5 GHz for extra capacity, or as dual 5 GHz with a dedicated scanning radio for always-on security, and an integrated BLE radio handles beacons and locationing. As part of the Universal (UTP) family it can run FortiGuard Universal Threat Protection services at the AP itself, and is managed by any FortiGate or by FortiLAN Cloud - with no separate per-AP management license. The U433F reached end of order on 23 October 2025 and is no longer available from stock; Fortinet continues support, firmware and FortiCare renewals through 2030, so existing fleets stay protected. For new rollouts the direct replacement is the Wi-Fi 7 FortiAP 443K, which keeps the same 4x4 external-antenna indoor form factor and adds the 6 GHz band, 4096-QAM and dual 10 GbE uplinks. Modern FortiAP F- and K-series natively support UTP, so the Universal distinction is no longer needed on current hardware.
The U433F is legacy – here is how to renew what you own or move to its current-generation successor.

Download the full datasheetHow the FortiAP U433F lines up against its current-generation replacements.
The FortiAP U433F is end-of-order. Its direct successor, the FortiAP 443K, keeps the same form factor on a newer Wi-Fi generation.
Mounts and power for the FortiAP U433F.
The FortiAP U433F reached end of order on 23 October 2025 and is classified as legacy. New hardware is no longer available from stock, but Fortinet continues firmware, security updates and FortiCare support through 23 October 2030, so existing deployments remain fully protected and renewable.
The direct successor is the Wi-Fi 7 FortiAP 443K, which keeps the same 4×4 external-antenna indoor form factor and adds the 6 GHz band, 4096-QAM and dual 10 GbE uplinks. The internal-antenna equivalent is the U431F, and the non-Universal 433F is a close match.
Universal access points such as the U433F could run FortiGuard Universal Threat Protection services directly at the AP. Modern FortiAP F- and K-series support UTP natively, so the separate Universal line was retired – the current Wi-Fi 7 FortiAP 443K covers the same role.
It is a tri-radio Wi-Fi 6 (802.11ax) AP with 4×4 MU-MIMO on both client radios, reaching 4804 Mbps per 5 GHz radio – about 9.9 Gbps aggregate with dual 5 GHz operation – and up to 512 clients per serving radio.
Existing FortiAP U433F units remain supported and renewable through 23 October 2030. FortiCare renewals for this model are currently out of stock online – contact us for a quote and we will source them. We are an authorized Fortinet Select Partner.
