CC115LRTKT RF Transmitter FSK IC Equivalent & Substitute Parts

Part Overview

The CC115LRTKT is an RF transmitter integrated circuit manufactured by Texas Instruments, designed for FSK, GFSK, and OOK modulation across ISM and SRD frequency bands (315MHz, 433MHz, 868MHz, 915MHz). The device delivers 12dBm output power with a maximum data rate of 600kbps and operates from 1.8V to 3.6V supply voltage.

The CC115LRTKT carries an Obsolete product status. Identifying equivalent substitute parts is essential for design continuity, procurement planning, and ensuring long-term component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CC115LRTKT is determined by strict equivalence across the following critical parameters:

Frequency coverage must match all bands: 315MHz, 433MHz, 868MHz, and 915MHz. Modulation support must include FSK, GFSK, and OOK protocols. Output power must equal 12dBm. Maximum data rate must be 600kbps or greater. Supply voltage range must encompass 1.8V to 3.6V. Package configuration must be 20-VFQFN Exposed Pad with identical pinout and thermal characteristics. Operating temperature range must span -40°C to 85°C. Transmit current must not exceed 34.2mA. Surface mount data interface and antenna connector requirements must be maintained.

The CC115LRGPT qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications. The primary distinction is packaging format: CC115LRGPT is supplied in Tape & Reel (TR) configuration versus the CC115LRTKT's standard packaging, and product status transition from Obsolete to Active.

Parameter Comparison

Engineering Selection Recommendations

The CC115LRGPT is the direct equivalent substitute for the CC115LRTKT. Both parts share identical electrical specifications, package geometry, and functional capabilities across all supported frequency bands and modulation protocols.

The CC115LRGPT offers the advantage of Active product status, ensuring continued manufacturer support, availability, and compliance with current regulatory standards. The Obsolete status of the CC115LRTKT indicates end-of-life designation, making the transition to CC115LRGPT appropriate for new designs and ongoing production requirements.

Both parts maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level remains constant at MSL 3 (168 Hours), requiring identical handling and storage protocols.

The packaging format difference (Tape & Reel for CC115LRGPT versus standard for CC115LRTKT) affects procurement and assembly logistics but does not impact electrical or mechanical compatibility. Selection between these formats depends on production volume and assembly equipment capabilities.

Frequently Asked Questions (FAQ)

Q: Can CC115LRGPT replace CC115LRTKT in existing designs without PCB modifications?

A: Yes. Both parts use identical 20-VFQFN Exposed Pad packages with matching pinout, footprint, and thermal characteristics. No PCB layout changes are required.

Q: What is the significance of the Obsolete status for CC115LRTKT?

A: Obsolete status indicates the manufacturer has discontinued production and support. The CC115LRGPT, with Active status, represents the current equivalent offering with ongoing availability and manufacturer backing.

Q: Are there differences in compliance certifications between the two parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and regulatory classifications (ECCN 5A991G, HTSUS 8542.39.0001).

Q: Does the Tape & Reel packaging of CC115LRGPT affect electrical performance?

A: No. Packaging format is a procurement and handling specification only. Electrical and functional performance remains identical.

Q: What are the critical parameters that must match for substitution?

A: Frequency range (315MHz, 433MHz, 868MHz, 915MHz), modulation support (FSK, GFSK, OOK), output power (12dBm), data rate (600kbps), supply voltage (1.8V to 3.6V), package type (20-VFQFN), and operating temperature range (-40°C to 85°C) must all be equivalent.

Q: Is the transmit current specification identical between both parts?

A: Yes. Both parts specify 34.2mA transmit current, ensuring equivalent power consumption and thermal management requirements.
