Procurement Notes

Verify component status carefully before integration planning. Official sources indicate the H1187T is obsolete or end-of-life. Confirm availability through authorized distributors or secondary markets if immediate procurement is required. Ensure compatibility with existing PCB layouts due to specific footprint requirements. Check for RoHS compliance details as documentation may vary. Validate lead times and stock levels independently as inventory data fluctuates rapidly for discontinued items.

Selection Notes

Consider alternative components from the same manufacturer family for new designs due to obsolete status. Evaluate physical dimension constraints against current board space requirements. Assess thermal performance within the specified operating temperature range. Verify interface compatibility with target network standards. Review datasheet specifications for electrical parameters to ensure system-level signal integrity meets design goals.
