TLK1201IRCPR Equivalent & Substitute Parts

Part Overview

The TLK1201IRCPR is a full-duplex IEEE 802.3 transceiver manufactured by Texas Instruments, housed in a 64-HVQFP surface mount package. This component operates within a supply voltage range of 2.3V to 2.7V and supports operating temperatures from -40°C to 85°C. The part is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLK1201IRCPR is determined by strict equivalence across the following critical parameters:

• Protocol compliance: IEEE 802.3 full-duplex transceiver architecture
• Electrical specifications: 2.3V to 2.7V supply voltage range
• Thermal operating range: -40°C to 85°C
• Physical form factor: 64-HVQFP (10x10) surface mount package
• Functional configuration: 1/1 driver/receiver pair
• Environmental compliance: ROHS3 and REACH certifications

The TLK2201BIRCPR meets all these criteria and is designated as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The TLK2201BIRCPR is the direct substitute for the obsolete TLK1201IRCPR. Both components share identical electrical specifications, thermal ratings, package geometry, and environmental compliance certifications. The TLK2201BIRCPR maintains Last Time Buy status, providing a defined procurement window for systems requiring IEEE 802.3 full-duplex transceiver functionality in the 64-HVQFP form factor. Component selection should prioritize the TLK2201BIRCPR for new designs and legacy system support where the TLK1201IRCPR is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the TLK2201BIRCPR directly replace the TLK1201IRCPR in existing designs?

A: Yes. Both components are identical in electrical specifications, supply voltage range (2.3V to 2.7V), operating temperature range (-40°C to 85°C), package type (64-HVQFP), and functional configuration (1/1 full-duplex IEEE 802.3 transceiver). No circuit modifications are required.

Q: What is the difference between the two part numbers?

A: The TLK1201IRCPR is obsolete, while the TLK2201BIRCPR is designated Last Time Buy. Both are manufactured by Texas Instruments and meet identical performance and compliance requirements.

Q: Are there any packaging differences between these parts?

A: No. Both components use the 64-HVQFP (10x10) surface mount package with identical moisture sensitivity levels (MSL 3, 168 hours) and are available in equivalent packaging formats.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both the TLK1201IRCPR and TLK2201BIRCPR are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory requirements.

Q: What is the inventory status for the substitute part?

A: The TLK2201BIRCPR has 7,400 pieces available as new original stock. Given its Last Time Buy status, procurement should be planned accordingly for long-term system support.
