Procurement Notes

Verify the specific suffix (UA) against official datasheets to confirm package type and pinout compatibility. Ensure procurement sources provide valid RoHS status documentation as required by project specifications. Cross-reference manufacturer part numbers with distributor listings to confirm authenticity and traceability before finalizing orders.

Selection Notes

Select this component when high-speed isolation is required alongside wide operating temperature ranges. The open collector output suits applications needing external pull-up resistors for voltage level translation. Consider the 16-SMD footprint for PCB layout constraints compared to through-hole alternatives.

Part Context

This device belongs to the Broadcom 81028 series of high-speed optocouplers. The series is designed for demanding industrial and commercial applications requiring fast signal transfer across isolation barriers. The 8102801UA variant specifically addresses needs for compact surface-mount integration with high reliability standards.

Replacement Considerations

Consult official substitution guides for compatible equivalents. Verify that any replacement maintains identical pin configurations, isolation ratings, and speed characteristics to ensure circuit functionality without redesign.
