TLK1002RGE Equivalent & Substitute Parts

Part Overview

The TLK1002RGE is a 2/2 Gigabit Ethernet transceiver manufactured by Texas Instruments, housed in a 24-VQFN (4x4) surface mount package with exposed pad. This component is classified as obsolete, indicating it has reached end-of-life status and is no longer recommended for new designs. The part operates at a supply voltage of 1.7V to 1.9V and maintains ROHS3 compliance with MSL Level 1 (unlimited moisture sensitivity).

Due to its obsolete status, identifying functionally equivalent substitute parts is essential for maintaining existing systems, supporting legacy product lines, and ensuring design continuity where TLK1002RGE components are no longer available from primary distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLK1002RGE is determined by the following critical parameters:

• Transceiver Type & Protocol: The substitute must function as an Ethernet transceiver to maintain interface compatibility
• Driver/Receiver Configuration: The 2/2 driver/receiver count defines the channel capacity and signal handling capability
• Supply Voltage Range: Operating voltage must align with system power delivery architecture
• Package Type & Mounting: Surface mount compatibility and physical footprint constraints
• Compliance & Certifications: RoHS3 compliance and regulatory status ensure design continuity

The identified substitute part, TLK100PHP, shares the same base product number (TLK100) and manufacturer (Texas Instruments), indicating a product family relationship. However, this substitute exhibits significant parameter variations that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TLK100PHP presents a substitute option within the Texas Instruments TLK100 product family; however, critical parameter differences require careful evaluation:

Voltage Supply Incompatibility: The TLK1002RGE operates at 1.7V–1.9V, while the TLK100PHP requires 3V–3.6V. Direct substitution without voltage regulation modifications is not feasible.

Protocol Downgrade: The TLK1002RGE supports Gigabit Ethernet, whereas the TLK100PHP operates at standard Ethernet speeds. This represents a functional reduction in data rate capability.

Channel Configuration Mismatch: The 2/2 driver/receiver configuration of the TLK1002RGE differs from the 1/1 configuration of the TLK100PHP, affecting multi-channel applications.

Package Footprint Difference: The 24-VQFN (4x4) package differs from the 48-HTQFP (7x7) package, requiring PCB layout redesign.

Product Status: Both parts are classified as obsolete or not recommended for new designs, indicating limited long-term availability.

Substitution of the TLK1002RGE with the TLK100PHP is only viable in applications where voltage regulation can be implemented, Ethernet (non-Gigabit) performance is acceptable, single-channel operation is sufficient, and PCB redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can the TLK100PHP directly replace the TLK1002RGE without modifications?

A: No. The TLK100PHP requires a different supply voltage (3V–3.6V versus 1.7V–1.9V), operates at standard Ethernet rather than Gigabit Ethernet speeds, and uses a different package footprint. Substitution requires voltage regulation design changes and PCB layout modifications.

Q: What is the primary difference in driver/receiver configuration between these parts?

A: The TLK1002RGE provides 2/2 drivers and receivers, supporting dual-channel transceiver operation. The TLK100PHP provides 1/1 drivers and receivers, supporting single-channel operation. Applications requiring multi-channel Ethernet transceiver functionality cannot use the TLK100PHP as a direct substitute.

Q: Are both parts RoHS3 compliant?

A: Yes, both the TLK1002RGE and TLK100PHP are ROHS3 compliant, ensuring regulatory alignment for applications subject to RoHS requirements.

Q: What is the significance of the different Moisture Sensitivity Levels (MSL)?

A: The TLK1002RGE has MSL Level 1 (unlimited moisture sensitivity), allowing indefinite storage without moisture control. The TLK100PHP has MSL Level 3 (168 hours), requiring controlled storage conditions and limiting shelf life to 168 hours after moisture exposure. This affects component handling, storage, and supply chain logistics.

Q: Why is the TLK100PHP classified as "Not For New Designs"?

A: This classification indicates the part is in end-of-life phase and Texas Instruments does not recommend its use in new product development. It may be available for legacy system support but should not be selected for designs entering production.

Q: What are the package considerations for substitution?

A: The TLK1002RGE uses a compact 24-VQFN (4x4) package, while the TLK100PHP uses a larger 48-HTQFP (7x7) package. Substitution requires complete PCB redesign to accommodate the different footprint, pin count, and thermal characteristics.
