CC1150-RTY1 Equivalent & Substitute Parts

Part Overview

The CC1150-RTY1 is an RF transmitter IC manufactured by Texas Instruments, designed for 2-FSK, ASK, GFSK, MSK, and OOK modulation across multiple frequency bands (300–348 MHz, 400–464 MHz, 800–928 MHz). The device operates at output power levels from -30 dBm to 10 dBm with a maximum data rate of 500 kBaud and is packaged in a 16-VQFN surface mount configuration.

The CC1150-RTY1 is classified as Obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, design continuity, or inventory replenishment where original stock is unavailable or depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CC1150-RTY1 is determined by strict alignment across the following critical parameters:

• Base Product Number: Both parts must share the CC1150 base designation, ensuring core silicon compatibility and pinout alignment.
• Package Type: Both parts must use the 16-VQFN Exposed Pad configuration to ensure PCB footprint compatibility.
• Frequency Coverage: Substitute parts must support the same frequency bands (300–348 MHz, 400–464 MHz, 800–928 MHz).
• Supply Voltage Range: Substitute parts must operate within the 1.8 V to 3.6 V range.
• Operating Temperature Range: Substitute parts must support -40°C to 85°C operation.
• Compliance Standards: Substitute parts must maintain ROHS3 compliance and REACH unaffected status.

The CC1150RGVT meets all substitution criteria and is classified as a direct equivalent within the CC1150 product family.

Parameter Comparison

Engineering Selection Recommendations

The CC1150RGVT is a direct functional equivalent to the CC1150-RTY1 and is suitable for substitution in applications requiring RF transmission across the specified frequency bands with identical electrical and mechanical parameters.

Product Status Advantage: The CC1150RGVT is classified as Active, ensuring continued availability and manufacturing support from Texas Instruments, whereas the CC1150-RTY1 is Obsolete.

Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support.

Output Power Consideration: The CC1150-RTY1 supports a variable output power range (-30 dBm to 10 dBm), while the CC1150RGVT operates at a fixed 10 dBm output. Applications requiring variable power attenuation must implement external power control circuitry when using the CC1150RGVT.

Moisture Sensitivity: The CC1150-RTY1 carries an MSL rating of 1 (Unlimited), while the CC1150RGVT carries an MSL rating of 3 (168 Hours). The CC1150RGVT requires controlled storage and handling conditions to prevent moisture absorption during assembly operations.

Packaging Format: The CC1150RGVT is supplied in Tape & Reel format, suitable for automated assembly processes. The CC1150-RTY1 was supplied in bulk packaging. Verify that your assembly equipment supports tape and reel input.

Frequently Asked Questions (FAQ)

Q: Can the CC1150RGVT be used as a direct drop-in replacement for the CC1150-RTY1?

A: Yes, the CC1150RGVT is a direct functional equivalent. Both parts share identical pinout, package dimensions (16-VQFN 4×4 mm), frequency coverage, supply voltage range, and operating temperature range. PCB footprints are interchangeable without modification.

Q: What is the difference in output power between these parts?

A: The CC1150-RTY1 supports variable output power from -30 dBm to 10 dBm, allowing software-controlled power adjustment. The CC1150RGVT operates at a fixed 10 dBm output. If your application requires power levels below 10 dBm, implement external attenuation or verify that fixed 10 dBm operation meets system requirements.

Q: Why does the CC1150RGVT have a different MSL rating?

A: The CC1150-RTY1 carries MSL 1 (Unlimited moisture sensitivity level), while the CC1150RGVT carries MSL 3 (168 Hours). MSL 3 requires that the component be stored in a controlled humidity environment and used within 168 hours of package opening. Ensure your assembly facility maintains proper moisture control and bake-out procedures before reflow soldering.

Q: Are there any differences in current consumption?

A: Transmitting current is comparable: CC1150-RTY1 draws 28.1 mA, while CC1150RGVT draws 29 mA. This 0.9 mA difference is negligible for most power budget calculations.

Q: What is the significance of the different packaging formats?

A: The CC1150-RTY1 was supplied in bulk packaging, while the CC1150RGVT is supplied in Tape & Reel (TR) format. Tape and reel packaging is standard for automated pick-and-place assembly. Verify that your assembly equipment supports tape and reel input, or request alternative packaging from your supplier if needed.

Q: Is the CC1150RGVT suitable for new designs?

A: Yes. The CC1150RGVT is classified as Active and is the recommended choice for new designs. It maintains full compliance with ROHS3 and REACH standards and benefits from ongoing manufacturing support from Texas Instruments.
