Substitute Part Grouping Explanation

Substitution of the USB2502-AEZG with the USB2512-AEZG is based on the following alignment of critical parameters:

• Functional Equivalence: Both devices operate as USB 2.0 Hub Controllers with 2-port configuration
• Package Compatibility: Both use 36-VFQFN Exposed Pad package with 6x6mm footprint, ensuring PCB layout compatibility
• Interface Standard: Both implement USB 2.0 protocol
• Supply Voltage Range: USB2512-AEZG operates within 3V ~ 3.6V, which is a subset of the USB2502-AEZG range (1.62V ~ 3.6V)
• Operating Temperature: Identical range of 0°C ~ 70°C
• Regulatory Compliance: Both maintain ROHS3 compliance and identical MSL rating

The USB2512-AEZG represents an active product with manufacturer support, addressing the obsolescence status of the USB2502-AEZG while maintaining core electrical and mechanical compatibility.

Engineering Selection Recommendations

The USB2512-AEZG is the manufacturer-recommended substitute for the obsolete USB2502-AEZG. Selection criteria are based on the following factors:

• Product Status: The USB2512-AEZG maintains Active status with ongoing manufacturer support, ensuring long-term availability and technical documentation access
• Regulatory Compliance: Both devices maintain ROHS3 compliance and identical moisture sensitivity ratings, satisfying environmental and handling requirements
• Supply Voltage Consideration: Designs operating at supply voltages below 3V require retention of the USB2502-AEZG or redesign to accommodate the USB2512-AEZG minimum voltage requirement
• Current Performance: The USB2512-AEZG demonstrates lower supply current (95mA vs 100mA), providing marginal power efficiency improvement
• Package Compatibility: Identical package footprint and pin configuration enable direct PCB substitution without layout modification

Frequently Asked Questions (FAQ)

Q: Can the USB2512-AEZG directly replace the USB2502-AEZG on existing PCBs?

A: Yes, for designs operating at supply voltages of 3V or higher. Both devices use identical 36-VFQFN Exposed Pad packages with 6x6mm footprint and matching pin configurations. Designs with supply voltages below 3V require circuit modification or retention of the USB2502-AEZG.

Q: What is the primary difference between these two hub controllers?

A: The USB2512-AEZG is the active product successor to the obsolete USB2502-AEZG. The key difference is the minimum supply voltage requirement: USB2512-AEZG requires 3V minimum, while USB2502-AEZG operates from 1.62V. Both maintain identical USB 2.0 2-port hub controller functionality and package specifications.

Q: Are there any firmware or software compatibility concerns?

A: Both devices implement USB 2.0 protocol with identical 2-port hub controller functionality. No firmware or software modifications are required for substitution in designs meeting the voltage requirements.

Q: What is the moisture sensitivity level, and how does it affect handling?

A: Both devices carry MSL 3 rating with 168-hour floor life. Components must be stored in controlled humidity environments and baked according to IPC standards before reflow soldering if floor life is exceeded.

Q: Is the USB2512-AEZG available in the same packaging options?

A: The USB2512-AEZG is supplied in Tray packaging, while the USB2502-AEZG was available in standard packaging. Both use the identical 36-QFN (6x6) physical package format suitable for automated assembly.
