CC1150RST RF Transmitter Equivalent & Substitute Parts

Part Overview

The CC1150RST is an RF transmitter IC manufactured by Texas Instruments, designed for 2-FSK, ASK, GFSK, MSK, and OOK modulation across 300MHz to 928MHz frequency bands. The device operates at supply voltages between 1.8V and 3.6V with output power ranging from -30dBm to 10dBm and supports data rates up to 500kBaud. The CC1150RST is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CC1150RST is determined by the following critical parameters:

• Base product number alignment (CC1150 family)
• Identical package and pinout (16-VQFN Exposed Pad, 4x4mm)
• Matching frequency band coverage (300MHz ~ 928MHz)
• Compatible data rate specification (500kBaud maximum)
• Overlapping supply voltage range (1.8V ~ 3.6V)
• Equivalent operating temperature range (-40°C ~ 85°C)
• Compliance certifications (RoHS3, REACH, ECCN, HTSUS)

The CC1150RGVT qualifies as a direct substitute based on these parameters. Both devices share the same base product number, package configuration, frequency bands, data rate capability, supply voltage range, and temperature specifications. Packaging format differences (Tape & Reel for CC1150RGVT versus standard packaging for CC1150RST) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CC1150RGVT is the qualified substitute for the obsolete CC1150RST. Selection is based on the following engineering criteria:

• Both devices maintain identical core specifications across frequency, data rate, supply voltage, and temperature ranges
• Package and pinout compatibility ensures direct PCB layout reuse without redesign
• The CC1150RGVT holds active product status, ensuring long-term availability and manufacturing support
• Both components meet ROHS3 compliance and carry identical REACH and ECCN classifications
• Moisture sensitivity level and handling requirements are equivalent
• Current consumption difference (28.1mA versus 29mA) is within normal manufacturing tolerance
• The CC1150RGVT specifies 10dBm fixed output power, whereas the CC1150RST supports a -30dBm to 10dBm range; applications requiring lower output power levels must evaluate this specification difference

Frequently Asked Questions (FAQ)

Q: Can the CC1150RGVT be used as a direct replacement for CC1150RST in existing designs?

A: Yes. Both devices share identical package geometry (16-VQFN, 4x4mm), pinout, frequency bands, data rate capability, supply voltage range, and operating temperature specifications. PCB layout and schematic modifications are not required.

Q: What is the primary reason for substitution?

A: The CC1150RST is classified as obsolete. The CC1150RGVT is an active product from the same manufacturer and base product family, ensuring continued availability and manufacturing support.

Q: Are there differences in modulation protocol support?

A: The CC1150RST explicitly supports 2-FSK, ASK, GFSK, MSK, and OOK modulation types. The CC1150RGVT is specified as UHF modulation. Both devices operate across identical frequency bands and data rates. Applications requiring specific modulation types should reference detailed datasheets for protocol implementation details.

Q: What is the difference in packaging format?

A: The CC1150RST is supplied in standard packaging, while the CC1150RGVT is supplied in Tape & Reel (TR) format. This affects procurement and handling procedures but does not impact electrical or mechanical compatibility.

Q: Are the current consumption specifications identical?

A: Transmitting current is specified as 28.1mA for CC1150RST and 29mA for CC1150RGVT. This 0.9mA difference is within normal manufacturing tolerance and does not affect system-level power budget calculations for most applications.

Q: What is the output power specification difference?

A: The CC1150RST supports output power from -30dBm to 10dBm, providing variable power control. The CC1150RGVT is specified at 10dBm fixed output. Applications requiring lower output power levels must evaluate whether fixed 10dBm operation meets system requirements.

Q: Are compliance certifications equivalent?

A: Yes. Both devices are ROHS3 compliant, REACH unaffected, and carry identical ECCN (5A991G) and HTSUS (8542.39.0001) classifications. Moisture sensitivity level is 3 (168 Hours) for both components.
