Key Parameters

Substitute Part Grouping Explanation

The TLK4211EARGTR has been identified with one active equivalent part: TLK4201EARGTR. This substitution is valid based on the following critical parameters that remain constant across both components:

• Identical package specification: 16-VFQFN Exposed Pad (16-VQFN 3x3)
• Matching surface mount mounting type
• Identical supply voltage range: 3V ~ 3.6V
• Same interface protocol: 2-Wire Serial
• Identical application domain: Digital High-Speed Link
• Matching RoHS3 compliance and MSL rating

The primary distinction between these parts is product status: TLK4211EARGTR is obsolete, while TLK4201EARGTR maintains active production status. Both components share the same electrical and mechanical specifications required for direct substitution in digital high-speed link interface applications.

Parameter Comparison

Engineering Selection Recommendations

The TLK4201EARGTR is the direct equivalent for the obsolete TLK4211EARGTR. Selection of the TLK4201EARGTR is supported by:
