Substitute Part Grouping Explanation

Substitution for the PI49FCT3803LE is determined by strict equivalence across the following electrical and mechanical parameters:

• Functional Equivalence: Fanout Buffer (Distribution) IC with 1:7 input-to-output ratio
• Frequency Specification: Maximum operating frequency of 156 MHz
• Signal Compatibility: CMOS/TTL input and output compatibility
• Electrical Characteristics: Supply voltage range 3V ~ 3.6V, operating temperature 0°C ~ 70°C
• Package Compatibility: 16-TSSOP (0.173", 4.40mm Width) surface mount package
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The PI49FCT3803LEX qualifies as a direct substitute based on identical electrical specifications, package form factor, and functional performance parameters.
