CC1101RTK Equivalent & Substitute Parts

Part Overview

The CC1101RTK is a radio frequency transceiver IC designed for ISM band applications below 1GHz, manufactured by Texas Instruments. This device operates across multiple frequency bands (300MHz–348MHz, 387MHz–464MHz, 779MHz–928MHz) and supports multiple modulation schemes including 2FSK, 4FSK, ASK, GFSK, MSK, and OOK. The CC1101RTK is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

The CC1101RGP qualifies as a direct substitute for the CC1101RTK based on identical electrical and mechanical specifications. Both parts share the same base product number (CC1101), RF transceiver architecture, frequency coverage, modulation support, and physical package format (20-VFQFN Exposed Pad). The primary distinction is product status: CC1101RTK is obsolete while CC1101RGP is active, and packaging format differs (CC1101RTK in standard packaging versus CC1101RGP in tube packaging).

Substitution is valid when the following parameters match:

• RF Family/Standard: General ISM < 1GHz
• Frequency Range: 300MHz–348MHz, 387MHz–464MHz, 779MHz–928MHz
• Modulation Schemes: 2FSK, 4FSK, ASK, GFSK, MSK, OOK
• Data Rate: 600kbps maximum
• Power Output: 12dBm
• Sensitivity: -116dBm
• Supply Voltage: 1.8V–3.6V
• Serial Interface: SPI
• Package Type: 20-VFQFN Exposed Pad
• Operating Temperature Range: -40°C to 85°C

Engineering Selection Recommendations

The CC1101RGP is the appropriate selection for new designs and ongoing production requiring CC1101RTK functionality. The CC1101RGP maintains active product status with Texas Instruments, ensuring continued availability and technical support. Both parts satisfy ROHS3 compliance and REACH requirements, with identical electrical performance and thermal operating range. The packaging difference (tube versus standard) does not affect electrical compatibility or PCB integration. Selection of CC1101RGP eliminates obsolescence risk associated with the CC1101RTK.

Frequently Asked Questions (FAQ)

Q: Can CC1101RGP directly replace CC1101RTK in existing designs? A: Yes. Both parts are electrically and mechanically identical, with matching frequency coverage, modulation support, power output, sensitivity, supply voltage requirements, and SPI interface. PCB layout and firmware remain unchanged.

Q: What is the primary reason to transition from CC1101RTK to CC1101RGP? A: The CC1101RTK is classified as obsolete. The CC1101RGP is the active equivalent, ensuring long-term availability and manufacturer support.

Q: Does packaging format affect circuit performance? A: No. The packaging difference (tube for CC1101RGP versus standard for CC1101RTK) is a logistics consideration only. The 20-VFQFN Exposed Pad package format and electrical specifications are identical.

Q: Are there compliance differences between these parts? A: No. Both parts are ROHS3 compliant and REACH unaffected, with identical MSL ratings of 3 (168 Hours).

Q: What frequency bands does CC1101RGP support? A: CC1101RGP operates across 300MHz–348MHz, 387MHz–464MHz, and 779MHz–928MHz, covering standard ISM band allocations below 1GHz.

Q: Is firmware or software modification required when switching to CC1101RGP? A: No. The SPI interface, register architecture, and command set are identical between both parts.
