Substitute Part Grouping Explanation
Substitution eligibility for the CY74FCT16823ATPACT is determined by strict alignment of the following critical parameters:
Functional equivalence requires identical configuration: dual 9-bit D-type flip-flop architecture with positive edge triggering, tri-state non-inverted outputs, and master reset functionality.
Package compatibility mandates the 56-TFSOP (0.240", 6.10mm Width) surface mount form factor to ensure direct board-level replacement without layout modifications.
Electrical operating range must encompass or match the original specification: -40°C to 85°C operating temperature range.
Compliance certifications must maintain ROHS3 compliance status and REACH unaffected designation to satisfy regulatory requirements.
The SN74ALVCH16823DGGR meets all substitution criteria through identical functional architecture, matching package specification, compatible operating temperature range, and equivalent compliance certifications.
