Substitute Part Grouping Explanation

Substitution of the CY74FCT163CTSOCT is determined by strict equivalence across the following critical parameters:

• Logic Type: Binary Counter
• Number of Elements: 1
• Number of Bits per Element: 4
• Direction: Up
• Reset Type: Synchronous
• Trigger Type: Positive Edge
• Voltage - Supply: 4.75 V ~ 5.25 V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

The substitute part CY74FCT163CTSOC matches all functional and electrical parameters required for direct substitution. The primary distinction between the main part and its substitute is product status and packaging format, not electrical or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CY74FCT163CTSOC is the direct substitute for the obsolete CY74FCT163CTSOCT. Both parts are manufactured by Texas Instruments and share identical electrical, functional, and mechanical specifications. The substitute part maintains active product status, ensuring ongoing availability and supply chain support.
