Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLK3101IRCP is determined by the following critical parameters:

Package Compatibility: The substitute must use the 64-HVQFP (10x10) package to ensure mechanical and electrical compatibility with existing PCB layouts and socket configurations.

Voltage Supply Range: The original part operates at 2.5V. Substitute parts must support this voltage level or provide overlapping supply voltage ranges to ensure proper circuit operation.

Operating Temperature Range: The substitute must maintain the -40°C to 85°C operating temperature specification to function within the same environmental conditions.

Interface Protocol: IEEE 802.3 compliance is required for network communication standards compatibility.

Compliance Standards: RoHS3 compliance and MSL rating of 3 (168 Hours) must be maintained to meet manufacturing and environmental requirements.

The TLK2501IRCP qualifies as a substitute based on matching package type (64-HVQFP), overlapping supply voltage range (2.3V ~ 2.7V encompasses 2.5V), identical operating temperature range, and equivalent compliance certifications.
