CC115LRTKR RF Transmitter FSK IC - Equivalent & Substitute Parts

Part Overview

The CC115LRTKR 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). This component operates at 12dBm output power with a maximum data rate of 600kbps and is housed in a 20-VFQFN surface mount package with exposed pad.

The CC115LRTKR carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this RF transmission architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CC115LRTKR is determined by strict alignment across the following critical parameters:

• Base Product Architecture: Both parts must share the CC115 base product number, ensuring identical silicon and functional design
• Frequency Support: Identical frequency band coverage (315MHz, 433MHz, 868MHz, 915MHz)
• Modulation Capability: Support for FSK, GFSK, and OOK modulation protocols
• Electrical Performance: Matching output power (12dBm), data rate (600kbps), transmit current (34.2mA), and supply voltage range (1.8V to 3.6V)
• Package Specification: Identical 20-VFQFN Exposed Pad package with 20-QFN (4x4) footprint
• Environmental Ratings: Matching operating temperature range (-40°C to 85°C) and MSL classification (3, 168 Hours)
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The CC115LRGPR meets all substitution criteria as a direct equivalent part, differing only in product status (Active vs. Obsolete) and packaging format (Cut Tape & Digi-Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The CC115LRGPR is a direct functional equivalent to the CC115LRTKR with complete electrical and mechanical compatibility. Selection between these parts should be based on the following factors:

Product Status Consideration: The CC115LRTKR is classified as obsolete, while the CC115LRGPR maintains active product status. For new designs, ongoing production, or long-term supply chain planning, the CC115LRGPR is the appropriate selection to ensure continued manufacturer support and availability.

Compliance and Certification: Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications in regulated markets and industries.

Packaging and Logistics: The CC115LRGPR is available in Cut Tape and Digi-Reel packaging formats, which may align with specific procurement, inventory management, or automated assembly workflows. The main part (CC115LRTKR) uses standard packaging. Packaging format selection should be coordinated with supply chain and manufacturing processes.

Functional Interchangeability: All electrical parameters, frequency support, modulation capabilities, and environmental ratings are identical. PCB layout, schematic integration, and firmware compatibility require no modification when transitioning from CC115LRTKR to CC115LRGPR.

Frequently Asked Questions (FAQ)

Q: Can CC115LRGPR be used as a direct replacement for CC115LRTKR in existing designs?

A: Yes. The CC115LRGPR is electrically and mechanically identical to the CC115LRTKR. No schematic changes, PCB modifications, or firmware updates are required. Both parts share the same 20-VFQFN package footprint, pin configuration, and electrical specifications.

Q: Why does the CC115LRTKR show obsolete status while CC115LRGPR is active?

A: Product status reflects Texas Instruments' manufacturing and support lifecycle. The CC115LRTKR has reached end-of-life status. The CC115LRGPR represents the active equivalent, ensuring continued availability, manufacturer support, and supply chain reliability for this RF transmitter architecture.

Q: Are there differences in frequency band support between these parts?

A: No. Both CC115LRTKR and CC115LRGPR support identical frequency bands: 315MHz, 433MHz, 868MHz, and 915MHz. Modulation types (FSK, GFSK, OOK) and data rate specifications (600kbps maximum) are also identical.

Q: What is the significance of the packaging format difference (Cut Tape & Digi-Reel vs. standard)?

A: Packaging format affects procurement, inventory handling, and automated assembly processes. Cut Tape and Digi-Reel formats are optimized for high-volume automated pick-and-place assembly. Standard packaging may be used for lower-volume or manual assembly workflows. Functional performance is identical regardless of packaging format.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both CC115LRTKR and CC115LRGPR are ROHS3 compliant, REACH unaffected, and rated for -40°C to 85°C operating temperature with MSL 3 (168 Hours) moisture sensitivity classification. All regulatory and environmental specifications are identical.

Q: Is the 34.2mA transmit current specification identical for both parts?

A: Yes. Current consumption during transmission is 34.2mA for both parts under identical operating conditions. Supply voltage range (1.8V to 3.6V) and output power (12dBm) are also identical.
