TLK100PHPR Equivalent & Substitute Parts

Part Overview

The TLK100PHPR is a 1/1 Ethernet transceiver manufactured by Texas Instruments, housed in a 48-HTQFP (7x7) surface mount package. This component is classified as Not For New Designs, indicating it has reached end-of-life status. The part operates within a 3V to 3.6V supply voltage range and supports operating temperatures from -40°C to 85°C. Due to its discontinued design status, identifying functionally compatible alternatives is essential for ongoing system support and new platform development.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLK100PHPR is determined by the following critical parameters:

• Ethernet Protocol Compliance: Both main and substitute parts must support Ethernet functionality
• Voltage Supply Range Compatibility: Supply voltage ranges must overlap or be compatible with system design
• Surface Mount Packaging: All alternatives must use surface mount technology
• RoHS3 Compliance: Environmental and regulatory compliance must be maintained
• Operating Temperature Range: Temperature specifications must support the intended application environment

The DP83822IRHBR qualifies as a substitute based on shared Ethernet interface functionality, Texas Instruments manufacture, surface mount deployment, and equivalent regulatory compliance. However, package form factor and pin configuration differ significantly, requiring circuit board redesign.

Parameter Comparison

Engineering Selection Recommendations

The DP83822IRHBR represents an active product alternative to the discontinued TLK100PHPR. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing environments.

The DP83822IRHBR operates across a wider supply voltage range (1.71V to 3.45V), encompassing the TLK100PHPR specification window of 3V to 3.6V. The substitute part features improved moisture sensitivity classification (MSL 2 versus MSL 3), reducing handling and storage constraints.

Package transition from 48-HTQFP to 32-VQFN requires circuit board layout modification and pin function remapping. This substitution is suitable for new platform development where design flexibility exists. For legacy system maintenance requiring pin-compatible replacement, alternative sources or custom solutions may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the DP83822IRHBR directly replace the TLK100PHPR without board modifications?

A: No. The DP83822IRHBR uses a 32-VQFN package compared to the TLK100PHPR's 48-HTQFP package. Pin count, pinout configuration, and physical footprint differ substantially. Circuit board redesign is required.

Q: Are the supply voltage ranges compatible?

A: The DP83822IRHBR supply range (1.71V to 3.45V) overlaps with the TLK100PHPR range (3V to 3.6V). Systems designed for 3V to 3.45V operation can use either component. Systems requiring operation below 1.71V or above 3.45V require verification against the DP83822IRHBR datasheet.

Q: What is the significance of the Product Status difference?

A: The TLK100PHPR is marked "Not For New Designs," indicating end-of-life status and limited future availability. The DP83822IRHBR is "Active," ensuring continued manufacturing support and long-term supply availability for new development.

Q: How do the moisture sensitivity levels affect handling?

A: The TLK100PHPR (MSL 3) requires reflow within 168 hours of moisture exposure. The DP83822IRHBR (MSL 2) allows one year of storage under controlled conditions, reducing handling complexity and storage costs.

Q: Are both parts suitable for the same temperature range applications?

A: The TLK100PHPR operates from -40°C to 85°C. Operating temperature data for the DP83822IRHBR was not provided in the available specifications. Consult the DP83822IRHBR datasheet to confirm temperature range compatibility with your application requirements.
