CC1100ERTKT Equivalent & Substitute Parts

Part Overview

The CC1100ERTKT is a radio frequency transceiver IC designed for ISM band applications below 1GHz, specifically supporting 470MHz–510MHz and 950MHz–960MHz frequency ranges. This component operates as a TxRx (transmit/receive) only device with integrated SPI serial interface and supports multiple modulation schemes including 2FSK, ASK, GFSK, MSK, and OOK.

The CC1100ERTKT carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this component.

Substitute Part Grouping Explanation

Substitution eligibility for the CC1100ERTKT is determined by strict alignment across the following critical parameters:

RF transceiver type and functionality (TxRx Only)
ISM band frequency support (470MHz–510MHz, 950MHz–960MHz)
Modulation capability (2FSK, ASK, GFSK, MSK, OOK)
Maximum data rate (500kBaud)
Output power and sensitivity specifications
Serial interface protocol (SPI)
Supply voltage range (1.8V–3.6V)
Package form factor (20-VFQFN Exposed Pad)
Environmental and compliance ratings (RoHS3, MSL 3)

The CC1100ERGPT meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is packaging configuration and product status.

Engineering Selection Recommendations

The CC1100ERGPT is the direct substitute for the CC1100ERTKT. Both components are manufactured by Texas Instruments and share identical electrical, functional, and mechanical specifications. The CC1100ERGPT holds active product status, ensuring ongoing manufacturer support and supply availability.

Selection of the CC1100ERGPT over the obsolete CC1100ERTKT is supported by:

Identical RF performance and modulation capability
Matching package form factor and pin configuration
Equivalent environmental operating range
Full compliance with RoHS3 and REACH regulations
Active product lifecycle status with manufacturer backing

The only operational difference is packaging format: the CC1100ERGPT is supplied in Tape & Reel configuration, which is standard for high-volume manufacturing and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CC1100ERGPT be used as a direct replacement for the CC1100ERTKT in existing designs?

A: Yes. Both parts are electrically and functionally identical. No circuit modifications or firmware changes are required. The pin configuration, electrical characteristics, and RF performance are equivalent.

Q: What is the difference between the CC1100ERTKT and CC1100ERGPT?

A: The primary difference is packaging configuration. The CC1100ERTKT uses standard tube or tray packaging, while the CC1100ERGPT is supplied in Tape & Reel format. Both use the same 20-VFQFN Exposed Pad package. The CC1100ERGPT also maintains active product status.

Q: Why is the CC1100ERTKT listed as obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for this specific part number variant. The CC1100ERGPT represents the current active equivalent.

Q: Are there any compatibility concerns when switching from CC1100ERTKT to CC1100ERGPT?

A: No compatibility concerns exist. Both parts conform to identical specifications for frequency range, modulation schemes, data rate, power output, sensitivity, supply voltage, and operating temperature. PCB layout and component placement remain unchanged.

Q: Does the Tape & Reel packaging of the CC1100ERGPT affect performance?

A: No. Tape & Reel packaging is a distribution format only and does not affect component performance, reliability, or electrical characteristics. It is optimized for automated pick-and-place assembly.

Q: Are both parts RoHS3 and REACH compliant?

A: Yes. Both the CC1100ERTKT and CC1100ERGPT are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the MSL rating, and does it differ between these parts?

A: Both parts carry MSL 3 (168 Hours) rating. This indicates moisture sensitivity level 3, requiring storage in controlled humidity conditions and a maximum floor life of 168 hours after bag opening before soldering.
