TLK1201RCP Equivalent & Substitute Parts

Part Overview

The TLK1201RCP is a full-duplex IEEE 802.3 transceiver manufactured by Texas Instruments, housed in a 64-HVQFP surface mount package. This component functions as a 1/1 transceiver for network interface applications requiring full-duplex communication compliance with IEEE 802.3 standards. The TLK1201RCP is classified as obsolete, making identification of suitable substitute components essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLK1201RCP is determined by strict alignment of the following critical parameters:

• Protocol compliance: IEEE 802.3 full-duplex transceiver functionality
• Electrical specifications: Supply voltage range 2.3V ~ 2.7V
• Physical form factor: 64-HVQFP (10x10) surface mount package
• Driver/receiver configuration: 1/1 transceiver architecture
• Environmental compliance: RoHS3 and REACH certification status
• Moisture sensitivity: MSL 3 classification

The TLK2201BRCP qualifies as a manufacturer-recommended substitute based on identical protocol, package, electrical supply range, and compliance certifications. Differences in operating temperature range and product status do not preclude substitution when system thermal requirements fall within the substitute's specified operating window.

Parameter Comparison

Engineering Selection Recommendations

The TLK2201BRCP is the manufacturer-recommended substitute for the obsolete TLK1201RCP. Both components maintain identical electrical specifications, package geometry, and compliance certifications. The TLK2201BRCP carries Last Time Buy status, indicating limited availability; procurement should be prioritized if this component is selected for system redesign or legacy support.

The operating temperature range difference (TLK2201BRCP: 0°C ~ 70°C versus TLK1201RCP: -40°C ~ 85°C) requires evaluation against actual system thermal requirements. Applications operating below 0°C or above 70°C cannot use the TLK2201BRCP as a direct substitute. For such applications, alternative solutions must be sourced.

Both components satisfy RoHS3 and REACH compliance requirements, supporting use in regulated markets and applications with environmental compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the TLK2201BRCP directly replace the TLK1201RCP in existing designs?

A: Yes, provided the system operating temperature remains within 0°C to 70°C. The electrical specifications, package footprint, and protocol compliance are identical. PCB layout and signal routing require no modification.

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

A: Operating temperature range. The TLK1201RCP operates from -40°C to 85°C, while the TLK2201BRCP operates from 0°C to 70°C. All other parameters are identical.

Q: Why is the TLK1201RCP classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The TLK2201BRCP represents the current-generation equivalent, though it carries Last Time Buy status, meaning availability is limited.

Q: Are there any package or pinout differences?

A: No. Both components use the 64-HVQFP (10x10) surface mount package with identical pinout and electrical characteristics.

Q: What does Last Time Buy status mean for the TLK2201BRCP?

A: Last Time Buy indicates the manufacturer will accept orders for a limited period before discontinuing the part. Procurement planning should account for this timeline if this component is selected.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are RoHS3 compliant and REACH unaffected, supporting equivalent regulatory compliance in all markets.
