Procurement Notes

Verify the specific suffix B02 against the manufacturer's current datasheet to confirm pinout and electrical characteristics. Ensure compatibility with the intended PoE standard (802.3af/at) and channel count requirements for the target design.

Selection Notes

Select this component when designing systems requiring integrated multi-channel PoE control. Consider the thermal performance and package type relative to the board layout. Verify that the input voltage range matches the system's power supply specifications.

Part Context

This part belongs to the SI3452 series of PoE controllers from Skyworks Solutions. It is designed for high-reliability network infrastructure equipment. The GMR suffix typically indicates a reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Check for direct substitutes within the SI3452 family or compatible competitors like Texas Instruments DP83867 series if channel count and protocol support align. Verify pin-to-pin compatibility before substitution.
