The Qualcomm QCA8337-AL3C-R is a Gigabit Ethernet switch IC with advanced features such as integrated PHYs (Physical Layer transceivers) for Ethernet connectivity, designed for consumer and networking applications. It typically supports 7 ports (5 gigabit ports and 2 gigabit uplinks), Power over Ethernet (PoE) support, and various advanced switching capabilities, such as VLAN, QoS, and IGMP snooping.

If you're looking for equivalent ICs to the QCA8337-AL3C-R, you’ll want to look for other Gigabit Ethernet switches with similar features, particularly ones with integrated PHYs and support for PoE (if necessary) and features such as VLAN and QoS.

Here are some equivalent ICs from other chip manufacturers:

1. Broadcom

• Broadcom BCM53125: This is a 5-port Gigabit Ethernet switch with integrated PHYs. It supports advanced features like VLAN, QoS, IGMP Snooping, and Energy Efficient Ethernet (EEE). It is widely used in home routers and enterprise Networking Equipment.

• Broadcom BCM53114: A 7-port Gigabit Ethernet switch that includes integrated PHYs for low cost and easy integration. It supports PoE, VLANs, QoS, and IGMP snooping.

  
  

2. Marvell

• Marvell 88E6350: A Gigabit Ethernet switch with 5 ports (integrated PHYs) that support PoE, VLANs, and QoS. It's used in small-to-mid-sized networking products and is known for its power efficiency and performance.

• Marvell 88E6172: A 7-port Gigabit Ethernet switch with integrated PHYs, and support for PoE, VLAN, QoS, and other advanced features. It's ideal for small office and home gateway applications.

  
  

3. Realtek

• Realtek RTL8380: A Gigabit Ethernet switch IC with up to 9 ports, integrated PHYs, and support for VLAN, QoS, and PoE. Realtek’s switches are commonly used in consumer networking equipment such as routers, switches, and gateways.

• Realtek RTL8309: A 5-port Gigabit Ethernet switch with integrated PHYs that supports VLANs, QoS, and Energy Efficient Ethernet. This chip is suitable for a variety of applications in home and small office routers.

  
  

4. Microchip / LAN9512

• Microchip KSZ9031: A Gigabit Ethernet switch IC with integrated PHYs. This chip supports VLANs, QoS, and PoE features. It is commonly used in small-to-medium networking systems, including home routers and access points.

• Microchip KSZ8863: A 3-port Gigabit Ethernet switch with integrated PHYs, providing VLAN, QoS, and PoE support. This is a good solution for smaller systems where fewer Ethernet ports are required but with high performance and low power.

  
  

5. Intel

• Intel I210: While primarily a PHY for Gigabit Ethernet, this is often used in conjunction with an external switch to build custom solutions. Intel also offers networking solutions with integrated switching capabilities.

• Intel I350: A more advanced Gigabit Ethernet controller that supports VLAN, QoS, and other advanced features, typically used in server or higher-end network equipment.

  
  

6. Texas Instruments

• TI DP83867: A Gigabit Ethernet PHY that supports Energy Efficient Ethernet, PoE, and VLANs. While not a complete switch like the QCA8337, it can be used in a design alongside an external switch IC to build custom Gigabit Ethernet solutions.

  
  

7. Broadcom / Netgear

• Netgear GS108: While this is not an IC but rather a switching solution (a retail Ethernet switch), it often uses Broadcom switch chips and could be indicative of similar technology used in consumer devices that may be powered by the Broadcom or Realtek solutions.

  
  

Key Features to Match When Choosing an Equivalent:

• Port Count: Ensure the switch has the same or similar number of ports. The QCA8337 has 7 ports in total (5 Gigabit Ethernet ports and 2 uplink ports).

• Integrated PHYs: The Qualcomm QCA8337 includes integrated Gigabit Ethernet PHYs. Ensure the replacement IC also integrates the PHYs, as this reduces design complexity and saves space.

• Power over Ethernet (PoE): If you need PoE support (for powering IP cameras, phones, etc.), look for a switch with integrated PoE capabilities.

• Advanced Features: Make sure the chip supports features like VLAN, QoS, IGMP snooping, Rate Limiting, and Energy Efficient Ethernet (EEE) if needed for your application.

• Performance and Latency: Pay attention to the performance and switching latency, especially if you’re working on high-performance networking applications.

  
  

Each of the alternatives listed above should provide similar or equivalent functionality to the Qualcomm QCA8337-AL3C-R in terms of Gigabit Ethernet switching, integrated PHY support, and advanced features like PoE, VLAN, and QoS. Depending on your specific application requirements (such as port count, PoE support, and feature set), any of these options could serve as an appropriate replacement.
