TLK110PTR Equivalent & Substitute Parts

Part Overview

The TLK110PTR is a full-duplex transceiver IC manufactured by Texas Instruments, designed for MII and RMII Ethernet interface applications. The device is packaged in a 48-LQFP (7x7mm) surface mount configuration and operates across a 3V to 3.6V supply voltage range with an operating temperature span of -40°C to 85°C.

The TLK110PTR carries a "Not For New Designs" product status designation. This status indicates that Texas Instruments has discontinued active development and support for this component line. Organizations requiring equivalent functionality for new designs or ongoing production must identify suitable substitute components that maintain electrical and mechanical compatibility while offering active product support and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLK110PTR is determined by the following critical parameters:

Protocol Compatibility: The substitute component must support both MII and RMII interface protocols to maintain functional equivalence in Ethernet transceiver applications.

Duplex Configuration: Full-duplex operation is required to match the bidirectional communication capability of the original part.

Driver/Receiver Configuration: The 1/1 driver/receiver ratio must be preserved in the substitute component.

Supply Voltage Range: The substitute must operate within or encompass the 3V to 3.6V supply voltage specification of the TLK110PTR.

Operating Temperature Range: The substitute must support the -40°C to 85°C operating temperature range.

Surface Mount Packaging: The substitute must utilize surface mount technology to maintain PCB assembly compatibility.

Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory alignment with the original component.

The DP83822IRHBR meets these substitution criteria through equivalent protocol support, matching duplex and driver/receiver specifications, compatible supply voltage range, and identical compliance certifications. The package format differs (32-VQFN versus 48-LQFP), requiring PCB layout redesign but maintaining functional and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DP83822IRHBR is designated as an active product by Texas Instruments, ensuring ongoing manufacturing support, availability, and technical documentation updates. This status directly addresses the obsolescence concern associated with the TLK110PTR's "Not For New Designs" classification.

Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new product designs and manufacturing operations.

The DP83822IRHBR supply voltage range (1.71V to 3.45V) encompasses the TLK110PTR specification (3V to 3.6V), providing voltage compatibility within the original operating window.

The package transition from 48-LQFP to 32-VQFN represents a reduction in pin count and footprint size. This change necessitates PCB schematic and layout modifications but does not compromise electrical functionality when proper signal routing and decoupling practices are implemented according to the DP83822IRHBR datasheet.

Frequently Asked Questions (FAQ)

Q: Can the DP83822IRHBR directly replace the TLK110PTR without PCB modifications?

A: No. The DP83822IRHBR uses a 32-pin VQFN package compared to the TLK110PTR's 48-pin LQFP package. Pin assignments differ, requiring schematic redesign and PCB layout changes. However, the functional interface protocols (MII, RMII) and electrical specifications remain compatible.

Q: What is the significance of the "Not For New Designs" status on the TLK110PTR?

A: This designation indicates that Texas Instruments has ended active development and support for the TLK110PTR product line. New designs should utilize active products such as the DP83822IRHBR to ensure long-term availability, technical support, and manufacturing continuity.

Q: Are the supply voltage ranges compatible between these two parts?

A: Yes. The DP83822IRHBR operates from 1.71V to 3.45V, which encompasses the TLK110PTR's 3V to 3.6V operating range. Designs operating within the original 3V to 3.6V window will function with the substitute component.

Q: What is the impact of the different Moisture Sensitivity Levels?

A: The TLK110PTR has MSL 1 (unlimited shelf life), while the DP83822IRHBR has MSL 2 (1-year shelf life). The DP83822IRHBR requires more stringent moisture control during storage and handling. Proper storage in dry conditions and appropriate baking procedures before reflow soldering are necessary to prevent moisture-induced failures.

Q: Do both parts support the same Ethernet interface protocols?

A: Yes. Both the TLK110PTR and DP83822IRHBR support MII and RMII protocols with full-duplex operation and 1/1 driver/receiver configuration, ensuring functional compatibility in Ethernet transceiver applications.
