TLK2211RCP Equivalent & Substitute Parts

Part Overview

The TLK2211RCP is an IEEE 802.3 transceiver manufactured by Texas Instruments, housed in a 64-HVQFP (10x10) surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The part operates within a 3V to 3.6V supply voltage range and maintains functionality across the -40°C to 85°C temperature spectrum.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLK2211RCP is determined by the following critical parameters:

• IEEE 802.3 protocol compliance
• 64-HVQFP (10x10) package compatibility
• Surface mount mounting type
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance and MSL rating consistency

The TLK2201BIRCP qualifies as a manufacturer-recommended substitute based on identical package specifications, protocol support, temperature range, and regulatory compliance. While the supply voltage range differs (2.3V to 2.7V versus 3V to 3.6V), this represents a distinct electrical characteristic that must be evaluated within the context of the target application's power supply architecture.

Parameter Comparison

Engineering Selection Recommendations

The TLK2201BIRCP is designated as the manufacturer-recommended substitute for the obsolete TLK2211RCP. Both components maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental consistency. The TLK2201BIRCP carries a Last Time Buy status, indicating limited future availability; procurement planning should account for this constraint.

The primary differentiation between these parts is the supply voltage range. The TLK2211RCP operates at 3V to 3.6V, while the TLK2201BIRCP operates at 2.3V to 2.7V. This voltage differential must be evaluated against the specific power supply architecture of the target application to determine compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TLK2201BIRCP directly replace the TLK2211RCP in existing designs?

A: Physical and functional compatibility is established through identical package specifications (64-HVQFP 10x10), protocol support (IEEE 802.3), and operating temperature range (-40°C to 85°C). However, the supply voltage range difference (2.3V–2.7V versus 3V–3.6V) requires verification against the application's power supply design.

Q: What is the significance of the Last Time Buy status for the TLK2201BIRCP?

A: Last Time Buy indicates that Texas Instruments has announced end-of-life for this component. Existing inventory may be available, but future procurement will not be possible. Long-term design strategies should account for this limitation.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components are ROHS3 compliant with identical MSL ratings (3, 168 Hours) and REACH unaffected status. No regulatory differentiation exists between the two parts.

Q: What package considerations apply to substitution?

A: Both the TLK2211RCP and TLK2201BIRCP use the 64-HVQFP (10x10) surface mount package. PCB layout, thermal management, and assembly processes remain unchanged during substitution.
