TLK1201ARCPR Equivalent & Substitute Parts

Part Overview

The TLK1201ARCPR is a full-duplex IEEE 802.3 transceiver manufactured by Texas Instruments, housed in a 64-HVQFP surface mount package. This component is classified as obsolete, necessitating identification of suitable substitute parts for ongoing design requirements and production continuity. The obsolete status requires engineers to evaluate available alternatives that maintain functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLK1201ARCPR is determined by the following critical parameters:

Functional Equivalence: Protocol (IEEE 802.3), transceiver configuration (1/1 full-duplex), and package type (64-HVQFP 10x10) must remain identical.

Electrical Compatibility: Supply voltage range (2.3V ~ 2.7V) and operating temperature range must be maintained or exceeded by the substitute part.

Physical Compatibility: Surface mount mounting type and 64-PowerVFQFP package footprint ensure PCB-level interchangeability.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be preserved.

The TLK2201BRCPR meets these substitution criteria as a direct functional equivalent from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The TLK2201BRCPR is the manufacturer-recommended substitute for the obsolete TLK1201ARCPR. Both components maintain identical electrical specifications, package geometry, and regulatory compliance status. The TLK2201BRCPR carries a Last Time Buy status, indicating limited availability; procurement planning should account for this lifecycle stage.

The operating temperature range of the TLK2201BRCPR (0°C ~ 70°C) is narrower than the TLK1201ARCPR (-40°C ~ 85°C). Applications requiring extended temperature operation below 0°C or above 70°C must evaluate this constraint against system requirements.

Both parts are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the TLK2201BRCPR directly replace the TLK1201ARCPR on existing PCBs?

A: Yes. Both components use identical 64-HVQFP (10x10) package geometry and surface mount footprint, enabling direct PCB-level substitution without layout modifications.

Q: What is the primary difference between these two parts?

A: The TLK2201BRCPR has a narrower operating temperature range (0°C ~ 70°C) compared to the TLK1201ARCPR (-40°C ~ 85°C). All other electrical and functional parameters are identical.

Q: Why is the TLK1201ARCPR obsolete?

A: The TLK1201ARCPR has reached end-of-life status. The TLK2201BRCPR represents the current-generation equivalent from Texas Instruments.

Q: Is the TLK2201BRCPR available for new designs?

A: The TLK2201BRCPR carries Last Time Buy status, indicating limited production availability. New design qualification should prioritize this component while inventory exists, or evaluate alternative solutions from the manufacturer's current product portfolio.

Q: Are there packaging differences between these parts?

A: No. Both components are supplied in 64-HVQFP (10x10) surface mount packages with identical moisture sensitivity levels (MSL 3, 168 hours).

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the TLK1201ARCPR and TLK2201BRCPR are ROHS3 compliant and REACH unaffected.
