Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CC1111F32RSPG3 is determined by strict equivalence across the following critical parameters:

RF Functional Equivalence: The substitute must support identical frequency bands (300MHz–348MHz, 391MHz–464MHz, 782MHz–928MHz) and modulation schemes (2FSK, ASK, GFSK, MSK, OOK).

Electrical Specifications: Supply voltage range (3V–3.6V), output power (10dBm), receiver sensitivity (-112dBm), and data rate capability (500kBaud maximum) must match exactly.

Memory and Interface Configuration: The substitute must provide 32kB Flash and 4kB SRAM, with identical serial interface support (I2S, USART, USB) and GPIO count (19 pins).

Physical and Environmental Compatibility: Package type (36-VFQFN Exposed Pad), mounting method (Surface Mount), operating temperature range (0°C–85°C), and moisture sensitivity level (MSL 3) must be identical.

Compliance Requirements: RoHS3 compliance and REACH unaffected status must be maintained.

The CC1111F32RSP meets all these criteria and is identified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The CC1111F32RSP is a direct functional and electrical equivalent to the CC1111F32RSPG3. Both devices are manufactured by Texas Instruments and share identical RF, electrical, memory, and interface specifications. The primary distinction is product status: the CC1111F32RSPG3 is Obsolete, while the CC1111F32RSP maintains Active status, ensuring continued availability and manufacturer support.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support. The packaging difference (Tube versus Tray) reflects distribution format only and does not affect electrical or functional performance.

For applications currently using CC1111F32RSPG3, direct substitution with CC1111F32RSP is supported without circuit modification or firmware revision.

Frequently Asked Questions (FAQ)

Q: Can CC1111F32RSP replace CC1111F32RSPG3 in existing designs?

A: Yes. Both parts are electrically and functionally identical across all RF, electrical, memory, interface, and environmental specifications. Direct substitution is supported without design changes.

Q: What is the difference between CC1111F32RSPG3 and CC1111F32RSP?

A: The devices are functionally equivalent. The primary differences are product status (Obsolete versus Active) and packaging format (Tube versus Tray). The "G3" suffix in CC1111F32RSPG3 indicates the tube packaging variant.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status. Environmental ratings, including MSL 3 (168 Hours), are identical.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format (Tube or Tray) is a distribution and handling consideration only. Electrical specifications, performance characteristics, and functional capabilities remain unchanged.

Q: Is CC1111F32RSP suitable for new product designs?

A: Yes. The Active product status of CC1111F32RSP ensures manufacturer support, continued availability, and compliance with current regulatory standards, making it the appropriate choice for new designs.

Q: What are the key parameters that determine substitution eligibility?

A: Frequency band support, modulation capability, data rate, output power, receiver sensitivity, memory configuration, serial interfaces, GPIO count, supply voltage, current consumption, operating temperature range, package type, and compliance certifications must all match exactly.
