Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLK2701IRCPR is determined by strict alignment of the following critical parameters:

• Package Compatibility: Both parts must use the 64-HVQFP (10x10) surface mount package to ensure PCB footprint and assembly compatibility.
• Voltage Supply Range: Both parts operate within 2.3V ~ 2.7V, ensuring direct power supply compatibility without circuit modification.
• Operating Temperature Range: Both parts support -40°C ~ 85°C, maintaining thermal performance across equivalent environmental conditions.
• Mounting Type: Surface mount technology remains consistent, preserving assembly process compatibility.
• Compliance Standards: Both parts maintain ROHS3 compliance and equivalent MSL ratings, ensuring regulatory and reliability alignment.

The TLK2501IRCPR qualifies as a substitute based on these parameters. While the TLK2501IRCPR operates at higher data rates (2.5Gbps) and includes serializer/deserializer functionality, these enhanced capabilities do not preclude substitution in applications designed for the TLK2701IRCPR, provided the interface protocol and electrical characteristics remain compatible within the defined parameter set.
